+
+ * __bb_exit_func.c: New file, from David Mosberger-Tang.
+
+ Thu Feb 9 16:56:07 1995 David Mosberger-Tang <davidm@piston.cs.arizona.edu>
+
+ * All *.c: More cleanup towards GNU format.
+
+ * gmon_out.h (struct gmon_hist_hdr, struct gmon_cg_arc_record):
+ replaced sizeof (bfd_vma) by size (char*) because Ken tells me
+ that bfd_vma is only guaranteed to be at least as big as a pointer.
+
+ (GMON_Record_tag): added explicit enumeration values to ensure
+ compatibility across compilers.
+
+ * gmon_io.c (get_vma, put_vma): replaced sizeof(bfd_vma) by
+ sizeof(char*).
+
+Tue Feb 7 17:24:12 1995 Ken Raeburn <raeburn@cujo.cygnus.com>
+
+ * All *.c and *.h files: Ran "indent -gnu". Cleaned up a couple
+ of constructs GNU indent couldn't handle. Block comments not yet
+ rewritten in GNU format.
+
+ * gprof.c (VERSION): Changed to 2.6, to get in sync for next
+ binutils release.
+
+Sun Feb 5 16:19:46 1995 David Mosberger-Tang <davidm@piston.cs.arizona.edu>
+
+ * symtab.c (symtab_finalize): ensure globals symbols really
+ are favored over static ones---even if their name looks less
+ preferable; this is important for HP-UX; for example, there
+ is a static label Ltext_something that aliases the global
+ symbol _start
+
+ * hist.c (hist_print): auto-scaling is now in effect for FSF-style
+ output only; also, auto-scaling is now performed based on
+ per-call, rather than total execution time, which is what it was
+ meant to be.
+
+ * gprof.h (File_Format): new type.
+
+ * gprof.c (VERSION): upped to 2.7---seems to be completely out of
+ sync with Cygnus version numbers though...
+
+ (long_options): renamed --gmon-info to --file-info, --width added,
+ renamed --old-file-format to --file-format
+ (main): dito; also added support to read prof files, but as
+ mon_out_read() is not implemented, it's #ifdef'd out for now
+
+ (usage): update to reflect new options.
+
+ * gmon_io.c: replaced "old_file_format" by more general
+ "file_format" option
+
+ * gmon.h (struct raw_phdr): fixed declaration for OSF/1.
+
+ * core.c (core_sym_class): added back check for __gnu_compiled and
+ ___gnu_compiled for the benefit of systems without
+ bfd_find_nearest_line() support
+
+ (get_src_info): now the libbfd is fixed, invoke bfd_find_nearest_line()
+ with section-relative addresses
+
+ (core_create_function_syms): get_src_info() calls are currently
+ enabled for OSF/1 only. It appears to work allright for SunOS
+ 4.1.x as well, but on SPARCs it gets painfully slow with the
+ current implementation of aout_32_find_nearest_line();
+ unfortunately, this means that static functions will not have their
+ filename printed in the call-graph function index; line-level
+ profiling should still work, but requires some patience
+
+ * cg_print.c (cg_print_index): sanitised printing of index when
+ using FSF-style output; in particular, output width is now controlled
+ via option --width and the function tries hard to keep columns
+ aligned even in the presence of (occasional) long names
+
+ * NOTES: a first shot at updating the documentation.
+
+Wed Feb 1 19:07:44 1995 David Mosberger-Tang <davidm@piston.cs.arizona.edu>
+
+ * core.c (core_create_function_syms): fixed computation of min_vma
+ and max_vma.
+
+ * *.c: removed rcsid.
+
+Tue Jan 31 16:18:18 1995 Ken Raeburn <raeburn@cujo.cygnus.com>
+
+ * Lots of changes from David Mosberger-Tang:
+
+ Tue Oct 25 19:20:14 1994 David Mosberger-Tang <davidm@piston.cs.arizona.edu>
+
+ * gprof.c (main): put parentheses around & within &&.
+
+ * basic_blocks.c (bb_read_rec): print warning message (once) when
+ ignoring basic-block execution counts.
+
+ * source.c (source_file_lookup_name): corrected second argument to
+ strcmp().
+
+ * hist.c (print_header): merged Fri Oct 21 18:58:02 1994 change by
+ Ken Raeburn <raeburn@cujo.cygnus.com> from binutils-2.5.1.
+
+ * gmon_io.c (gmon_out_read): the output stule STYLE_GMON_INFO is now
+ supported both for old and new (versioned) gmon.out files. Old
+ files are identified as version 0.
+
+ * gmon.h (struct raw_arc): count field is now sizeof(long) bytes
+ long (instead of 4) because that is what OSF/1 v3.0 uses.
+
+ * core.c: minor fixes and debugging info changes.
+
+ Sun Sep 11 18:47:47 1994 David Mosberger-Tang (davidm@piston.cs.arizona.edu)
+
+ * core.c (core_init): if .text cannot be found, try $CODE$ (the
+ name of the text-section under HP-UX).
+
+ * hist.c (hist_assign_samples): fixed off-by-one bug: highpc
+ points one past the last sampling bin, so hist_scale should be
+ computed as "hist_scale /= hist_num_bins", not "hist_scale /=
+ hist_num_bins - 1".
+
+ * gmon_io.c, hist.c, hist.h: renamed hist_num_samples to
+ hist_num_bins.
+
+ * configure.in: added alpha-*-*) for per-target config.
+
+ * alpha.c, alpha.h: created.
+
+ * gprof.c (default_excluded_list): <locore>, <hicore> added.
+
+ * core.c (core_create_function_syms, core_create_line_syms):
+ explicitly keep two sentinels "<locore>" and "<hicore>" that catch
+ all addresses outside the text-space. Thus, sym_lookup(&symtab,
+ addr) continues to guarantee not to return 0 on any address. It
+ also avoids incorrectly crediting the first/last symbol in the
+ text-space.
+
+ * core.c (core_create_line_syms): always create function symbols
+ first, then merge in line symbols; this is so that if parts of the
+ program were compiled without -g, function-level symbols are
+ available still.
+
+ * utils.c (print_name_only): support for print_path added.
+
+ * symtab.c (cmp_addr): also use is_func flag in comparison.
+ (symtab_finalize): return immediately when table empty; now
+ more careful about getting rid of the right duplicate symbol.
+
+ * sparc.c (find_call): many fixes---this function was rather
+ botched in binutils-2.4 already; it should work again.
+
+ * source.c (source_file_lookup_path): PATH is now strdup'ed (it is
+ not good to rely on get_src_info() to return distinct string
+ pointers).
+
+ * search_list.c (search_list_append): added cast for xmalloc().
+
+ * hist.c: added explicit initialization to some of the global
+ variables; fixed SItab (scales were off by a factor of 10).
+
+ * hist.h: include of bfd.h added.
+
+ * gprof.c, gprof.h (print_path): added.
+
+ * gprof.h (MAX): fixed.
+
+ * gmon_out.h: renamed gmon_time_hist_hdr to gmon_hist_hdr.
+
+ * gmon_io.c: added some casts to (long) so we can always print as %lx
+
+ * core.c (core_get_text_space): fixed to make it work.
+
+ * cg_print.c (cg_print_index): added support for print_path option.
+
+ * cg_dfn.h (cg_dfn): wrap prototype in PARAMS().
+
+ * call_graph.c, gmon_io.c, hist.c: avoid taking address of array
+ as some compilers complain (e.g., DEC's OSF/1 compiler)
+
+ * basic_blocks.c, gmon_io.c, hist.c, source.c, sym_ids.c,
+ symtab.c: calls to memset() had 2nd and 3rd args reversed.
+
+ Sat Sep 10 21:53:13 1994 David Mosberger-Tang (davidm@piston.cs.arizona.edu)
+
+ * gprof.c: added "_mcount" to default_excluded_list.
+ (main): if output_style==0 and there is either a histogram or a
+ call-graph, always generate flat and call-graph, no matter what
+ line_granularity is set to.
+
+ * source.c (source_file_lookup_name): if searching for sf->name
+ fails, try again with filename obtained after stripping off any
+ partial path from sf->name.
+
+ * gprof.h (SRCDEBUG): added.
+
+ * search_list.c (search_list_append): directories were added in wrong
+ order.
+
+ * reimplemented selection mechanism from ground up; it is now possible
+ to accurately control what gets included/excluded in each of the
+ output styles; a "symbol-specification" (spec) is the basic means
+ to select a set of symbols; a spec has the syntax:
+
+ spec == (FILENAME:(FUNCNAME|LINE_NUM) | NAME).
+ arc == spec/spec.
+
+ any of the terminal symbols can be empty, in which case they
+ match anything (wildcards). NAME is interpreted as a FILENAME
+ if it contains a dot (e.g., foo.c), as LINE_NUM if it starts
+ with a digit, and as FUNCNAME otherwise.
+
+ For example, to get a call-graph display that ignores arcs
+ from foo() to bar(), you'd say "--no-graph=foo/bar"; to
+ show only arcs into bar() (no matter what the caller),
+ you'd say "--graph=/bar"; and to get a call-graph without
+ any arc info, you'd say "--graph=/"; similarly, to
+ get a flat profile without mcount, you'd say "--no-flat=mcount"
+ and to get a flat profile that shows includes all functions
+ you'd say "--flat=""" (i.e., an empty spec)
+
+ * hist.c (hist_print): top_time wasn't initialized to 0.0.
+
+ Fri Sep 9 01:10:21 1994 David Mosberger-Tang (davidm@piston.cs.arizona.edu)
+
+ * gmon_out.h: all headers now declared in terms of characters
+ to avoid getting into trouble with different compilers introducing
+ different amount of padding; the code already accessed the fields
+ through bfd functions, so that didn't have to change.
+
+ * hist.c (hist_read_rec, hist_write_rec): added support for
+ collection pc histograms measuring quantities other than time;
+ the histogram header now includes a field that specifies the
+ dimension of the quantity measured by the histogram bins
+ (normally, this is "seconds", but other meaningful dimensions
+ include such things as "I-cache misses", "instruction issue stalls"
+ etc.); there is also a field to specify a one-character
+ abbreviation for the dimension; in the case of time, this would
+ be 's'; in most other cases it probably would be '1' (not a physical
+ dimension).
+
+ Thu Sep 8 16:05:08 1994 David Mosberger-Tang (davidm@piston.cs.arizona.edu)
+
+ * gprof.c, gmon_io.[ch]: BSD_COMPATIBLE is gone and new_file_version
+ has become old_file_version; gmon_io.c now always supports old-style
+ gmon.out files; it first tries to read gmon.out as a new version
+ file, if that fails, it tries to read it in the old format;
+ although not very likely, it is possible for gprof to mistake an
+ old-style file as a new one (the first 4 bytes would have to
+ be "gmon"---including the trailing '\0'); in that case, it is
+ necessary to specify --old-file-version
+
+ * gprof.h: removed dependency on SYSV; the code now always uses
+ strrchr(), memset(), and memcpy() and does not include either
+ of string.h or strings.h; this should make gprof compile on
+ any (Unix) system without configuration (per suggestion of
+ raeburn@cygnus.com)
+
+ * gprof.c (usage): fixed location of --new-file-format option.
+
+ * cg_arcs.c (propagate_flags): fixed typo in declaration.
+
+ * flat_bl.m: removed formfeed at end of file; the form-feed
+ is now printed cg_print.c only when necessary.
+
+ * major rewrite of gprof---too many changes to mention all of
+ them. new features:
+
+ + -l now requests profiling at the line level (as opposed
+ to function level); in this mode, gprof creates a "symbol"
+ (aka name-list entry) for each line of source code, instead
+ of one per function)
+
+ + support for a new gmon.out file format; the new format
+ consists of a header with a magic and a version number,
+ followed by a sequence of profile data; profile data
+ can any of: (a) PC histogram, (b) call-graph arcs, or
+ (c) basic-block execution counts; the version number makes
+ it possible to extend gmon.out in a backwards compatible
+ fashion
+
+ + support for tcov style annotated output: if the gmon.out file
+ contains basic-block execution counts, the user can request
+ the generation of annotated source files, much like Sun's
+ tcov used to do
+
+ + long options
+
+ + new scheme to suppress symbols that aren't function names
+ (e.g., avoids mistaking a goto label as a function)
+
+ + reorganized source code to make it more managable; as a
+ side effect, gprof now compiles cleanly with "gcc -Wall"
+
+ Thu Sep 1 15:46:49 1994 David Mosberger-Tang (davidm@piston.cs.arizona.edu)
+
+ * gprof.c (funcsymbol): bfd_find_nearest_line() is now used as a
+ final cross-check to determine whether a static symbol should be
+ considered as a function-name.
+
+ Fri Aug 5 19:32:36 1994 David Mosberger-Tang (davidm@piston.cs.arizona.edu)
+
+ * gmon_io.c (gmon_out_read): recognize "-" as the filename for
+ stdin; this is useful if you wanna keep gmon.out files compressed;
+ this way you can "gzcat" the compressed file into gprof.
+
+ * gprof.c: flag_min_count now initialized with 1 instead of 0.
+
+ * basic_blocks.c (bb_annotate_source): added support for creating
+ .tcov files when option flag_annotate_make_files is TRUE.
+ (annotate_with_count): all counts less than the minimum count
+ specified by -m are now annotated with hash-marks.
+
+ * gprof.c (main): -A is now followed by a string of option chars.
+
+ * basic_blocks.c (annotate_with_count): replaced b->count with
+ cnt.
+
+ * source.c: flag_annotate_source replaced by source_lock_map.
+
+ * source.h: source_lock_map added.
+
+ * gprof.c (main): new command-line syntax: -S simply specifies
+ which source-files user is interested in; -A requests annotated
+ source files and -AA requests that all lines in a source file
+ are annotated.
+
+ Thu Aug 4 23:27:03 1994 David Mosberger-Tang (davidm@piston.cs.arizona.edu)
+
+ * basic_blocks.c (PATH_MAX): if undefined, define as 1024.
+
+ * sparc.c, i386.c, tahoe.c, vax.c: added include of "time_hist.h"
+ so s_lowpc etc. get declared.
+
+ * arcs.h (doarcs): created.

+ * arcs.c: reordered static functions such that they get defined
+ before use.
+
+ * gprof.c (main): added options:

+ Fri Jul 1 15:23:50 1994 David Mosberger-Tang (davidm@piston.cs.arizona.edu)
+
+ * gprof.c (asgnsamples): computation of "pcl" and "pch" depended
+ on the fact being able to store a long in a double without loss of
+ precision; this does not hold on machines with 64 bit longs and 64
+ bit doubles.
+
+Fri Oct 21 18:58:02 1994 Ken Raeburn <raeburn@cujo.cygnus.com>

+ (printgprof, printindex): Ditto.
+
+Thu Sep 1 10:40:45 1994 Jeff Law (law@snake.cs.utah.edu)
+
+ * gprof.h (kfromlist, ktolist, flist, Flist, elist, Elist): Make
+ decls extern to keep native HP compiler quiet.
+
+Tue Aug 30 11:12:13 1994 Ian Lance Taylor (ian@sanguine.cygnus.com)
+
+ * gprof.c (funcsymbol): Ignore ___gnu_compiled as well as

+
+ * configure.in: Change i386-*-* to i[345]86-*-*.

+
+Tue May 17 15:30:22 1994 E. Michael Smith (ems@cygnus.com)
+
+ * Makefile.in (.m.c:): Added .SUFFIXES : .m
+ so flat_bl.c would make from flat_bl.m file.
+
+Thu May 5 19:23:24 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
+
+ * Makefile.in (install-info): Check for gprof.info in build dir,

+
+Wed Jan 6 00:58:09 1993 david d `zoo' zuhn (zoo at cirdan.cygnus.com)
+
+ * Makefile.in: fix install rule for $(PROG)
+
+Fri Oct 9 11:25:41 1992 Mark Eichin (eichin@cygnus.com)
+
+ * gprof.1: updated SYNOPSIS to match actual behavior.
+
+Mon Oct 5 17:50:16 1992 Per Bothner (bothner@cygnus.com)
+
+ * gen-c-prog.awk: New awk script, lightly changed from
+ previously deleted make-c-prog.awk. Converts a text file
+ to a c function that prints that text.
+ * flat_bl.m, fsf_callg_bl.m, bsd_callg_bl.m: New files.
+ Inputs to gen-c-prog.awk, containing text describing
+ gprof output.
+ * blurbs.c: Removed. Use *_bl.c instead.
+ * Makefile.in: Use gen-cprog.awk to generate *_bl.c files
+ from *_bl.m files. Also, improve *clean rules.
+ * printgprof.c (printgprof): Usw new function names from *_bl.c.
+
+
+Sun Aug 30 19:54:53 1992 Per Bothner (bothner@rtl.cygnus.com)
+
+ * gprof.h, gprof.c, printfgprof.c: Add support for two
+ output styles: The default is similar to the old FSF gprof,
+ while -T sets the variable bsd_style_output, which causes
+ output matching Berkeley's gprof. The biggest differences
+ are that with the FSF style output, the flat profile comes
+ before the call graph; numbers come before explanations;
+ and there is less gratuitous white space.
+ * gprof.h, gprof.c, printfgprof.c: New discard_underscores
+ variable causes discarding of initial underscores when
+ printing symbol names. It is set unless there is a "main"
+ symbol (without an underscore).
+ * printfgprof.c: New function printnameonly(), called
+ by printname(). It handles stripping of initial '_',
+ as well as C++ name-demangling.
+ * gprof.callg, gprof.flat, make-c-prog.awk: Removed.
+ It is just as convenient to edit blurbs.c directly.
+ * Makefile.in: Removed rule for making blurbs.c.
+ * blurbs.c: This is now a true source file (as opposed
+ to being generated from gprof.callg and gprof.flat).
+ Change style to use one long string literal, instead of
+ one literal per output line. Add FSF-style blurb for call graph.
+
+Wed Aug 19 14:36:39 1992 Ian Lance Taylor (ian@cygnus.com)
+
+ * Makefile.in: always create installation directories.
+
+Wed Aug 12 15:14:14 1992 Mark Eichin (eichin@cygnus.com)
+
+ * Makefile.in: change ${MACHINE} to $(MACHINE).
+
+Sun Jul 19 17:34:01 1992 david d `zoo' zuhn (zoo at cirdan.cygnus.com)
+
+ * Makefile.in: removed installation of the now useless
+ call.{flag,callg} files.
+
+ * gprof.1: now uses the standard man macros instead of the new BSD
+ mandoc macros.
+
+Sun Jul 12 19:06:00 1992 John Gilmore (gnu at cygnus.com)
+
+ * configure.in: Remove host section, expand target section.
+ * config/mt-{tahoe,vax}: Add, to match existing support files.
+ * config/tmake-*: Remove leftover crud.
+
+ * blurbs.c: New file, created from gprof.flat and gprof.callg by
+ * make-c-prog.awk: which processes text files into C programs.
+ * printgprof.c (flatprofheader, gprofheader): Call new functions
+ to print blurbs.
+ (printblurb): Remove.
+ * Makefile.in: Infrastructure to build blurbs.
+ * pathnames.h: has been removed. Gprof now has no filename
+ dependencies in it.
+ * gprof.c: Lint.
+
+Sat Jul 11 18:07:21 1992 david d `zoo' zuhn (zoo at cirdan.cygnus.com)
+
+ * Makefile.in: define man1dir and install the man page
+
+Fri Jul 10 21:14:08 1992 david d `zoo' zuhn (zoo@cygnus.com)
+
+ * Makefile.in: added dummy info and install-info targets
+
+Thu Jun 4 11:34:02 1992 Mark Eichin (eichin at cygnus.com)
+
+ * lookup.c: fixed fencepost in nllookup and added dbg_nllookup for
+ help in debugging the problem (with -DDEBUG)
+ * gprof.c: symbol values are now real values, don't add the vma
+ anymore. (done for solaris; should verify this on other platforms)
+ * ChangeLog: created.

+
+This file documents the changes and new features available with this
+version of GNU gprof.
+
+* New Features
+
+ o Long options
+
+ o Supports generalized file format, without breaking backward compatibility:
+ new file format supports basic-block execution counts and non-realtime
+ histograms (see below)
+
+ o Supports profiling at the line level: flat profiles, call-graph profiles,
+ and execution-counts can all be displayed at a level that identifies
+ individual lines rather than just functions
+
+ o Test-coverage support (similar to Sun tcov program): source files
+ can be annotated with the number of times a function was invoked
+ or with the number of times each basic-block in a function was
+ executed
+
+ o Generalized histograms: not just execution-time, but arbitrary
+ histograms are support (for example, performance counter based
+ profiles)
+
+ o Powerful mechanism to select data to be included/excluded from
+ analysis and/or output
+
+ o Support for DEC OSF/1 v3.0
+
+ o Full cross-platform profiling support: gprof uses BFD to support
+ arbitrary, non-native object file formats and non-native byte-orders
+ (this feature has not been tested yet)
+
+ o In the call-graph function index, static function names are now
+ printed together with the filename in which the function was defined
+ (required bfd_find_nearest_line() support and symbolic debugging
+ information to be present in the executable file)
+
+ o Major overhaul of source code (compiles cleanly with -Wall, etc.)
+
+* Supported Platforms
+
+The current version is known to work on:
+
+ o DEC OSF/1 v3.0
+ All features supported.
+
+ o SunOS 4.1.x
+ All features supported.
+
+ o Solaris 2.3
+ Line-level profiling unsupported because bfd_find_nearest_line()
+ is not fully implemented for Elf binaries.
+
+ o HP-UX 9.01
+ Line-level profiling unsupported because bfd_find_nearest_line()
+ is not fully implemented for SOM binaries.
+
+* Detailed Description
+
+** User Interface Changes
+
+The command-line interface is backwards compatible with earlier
+versions of GNU gprof and Berkeley gprof. The only exception is
+the option to delete arcs from the call graph. The old syntax
+was:
+
+ -k fromname toname
+
+while the new syntax is:
+
+ -k fromname/toname
+
+This change was necessary to be compatible with long-option parsing.
+Also, "fromname" and "toname" can now be arbitrary symspecs rather
+than just function names (see below for an explanation of symspecs).
+For example, option "-k gprof.c/" suppresses all arcs due to calls out
+of file "gprof.c".
+
+*** Sym Specs
+
+It is often necessary to apply gprof only to specific parts of a
+program. GNU gprof has a simple but powerful mechanism to achieve
+this. So called {\em symspecs\/} provide the foundation for this
+mechanism. A symspec selects the parts of a profiled program to which
+an operation should be applied to. The syntax of a symspec is
+simple:
+
+ filename_containing_a_dot
+ | funcname_not_containing_a_dot
+ | linenumber
+ | ( [ any_filename ] `:' ( any_funcname | linenumber ) )
+
+Here are some examples:
+
+ main.c Selects everything in file "main.c"---the
+ dot in the string tells gprof to interpret
+ the string as a filename, rather than as
+ a function name. To select a file whose
+ name does contain a dot, a trailing colon
+ should be specified. For example, "odd:" is
+ interpreted as the file named "odd".
+
+ main Selects all functions named "main". Notice
+ that there may be multiple instances of the
+ same function name because some of the
+ definitions may be local (i.e., static).
+ Unless a function name is unique in a program,
+ you must use the colon notation explained
+ below to specify a function from a specific
+ source file. Sometimes, functionnames contain
+ dots. In such cases, it is necessar to
+ add a leading colon to the name. For example,
+ ":.mul" selects function ".mul".
+
+ main.c:main Selects function "main" in file "main.c".
+
+ main.c:134 Selects line 134 in file "main.c".
+
+IMPLEMENTATION NOTE: The source code uses the type sym_id for symspecs.
+At some point, this probably ought to be changed to "sym_spec" to make
+reading the code easier.
+
+*** Long options
+
+GNU gprof now supports long options. The following is a list of all
+supported options. Options that are listed without description
+operate in the same manner as the corresponding option in older
+versions of gprof.
+
+Short Form: Long Form:
+----------- ----------
+-l --line
+ Request profiling at the line-level rather
+ than just at the function level. Source
+ lines are identified by symbols of the form:
+
+ func (file:line)
+
+ where "func" is the function name, "file" is the
+ file name and "line" is the line-number that
+ corresponds to the line.
+
+ To work properly, the binary must contain symbolic
+ debugging information. This means that the source
+ have to be translated with option "-g" specified.
+ Functions for which there is no symbolic debugging
+ information available are treated as if "--line"
+ had not been specified. However, the line number
+ printed with such symbols is usually incorrect
+ and should be ignored.
+
+-a --no-static
+-A[symspec] --annotated-source[=symspec]
+ Request output in the form of annotated source
+ files. If "symspec" is specified, print output only
+ for symbols selected by "symspec". If the option
+ is specified multiple times, annotated output is
+ generated for the union of all symspecs.
+
+ Examples:
+
+ -A Prints annotated source for all
+ source files.
+ -Agprof.c Prints annotated source for file
+ gprof.c.
+ -Afoobar Prints annotated source for files
+ containing a function named "foobar".
+ The entire file will be printed, but
+ only the function itself will be
+ annotated with profile data.
+
+-J[symspec] --no-annotated-source[=symspec]
+ Suppress annotated source output. If specified
+ without argument, annotated output is suppressed
+ completely. With an argument, annotated output
+ is suppressed only for the symbols selected by
+ "symspec". If the option is specified multiple
+ times, annotated output is suppressed for the
+ union of all symspecs. This option has lower
+ precedence than --annotated-source
+
+-p[symspec] --flat-profile[=symspec]
+ Request output in the form of a flat profile
+ (unless any other output-style option is specified,
+ this option is turned on by default). If
+ "symspec" is specified, include only symbols
+ selected by "symspec" in flat profile. If the
+ option is specified multiple times, the flat
+ profile includes symbols selected by the union
+ of all symspecs.
+
+-P[symspec] --no-flat-profile[=symspec]
+ Suppress output in the flat profile. If given
+ without an argument, the flat profile is suppressed
+ completely. If "symspec" is specified, suppress
+ the selected symbols in the flat profile. If the
+ option is specified multiple times, the union of
+ the selected symbols is suppressed. This option
+ has lower precedence than --flat-profile.
+
+-q[symspec] --graph[=symspec]
+ Request output in the form of a call-graph
+ (unless any other output-style option is specified,
+ this option is turned on by default). If "symspec"
+ is specified, include only symbols selected by
+ "symspec" in the call-graph. If the option is
+ specified multiple times, the call-graph includes
+ symbols selected by the union of all symspecs.
+
+-Q[symspec] --no-graph[=symspec]
+ Suppress output in the call-graph. If given without
+ an argument, the call-graph is suppressed completely.
+ With a "symspec", suppress the selected symbols
+ from the call-graph. If the option is specified
+ multiple times, the union of the selected symbols
+ is suppressed. This option has lower precedence
+ than --graph.
+
+-C[symspec] --exec-counts[=symspec]
+ Request output in the form of execution counts.
+ If "symspec" is present, include only symbols
+ selected by "symspec" in the execution count
+ listing. If the option is specified multiple
+ times, the execution count listing includes
+ symbols selected by the union of all symspecs.
+
+-Z[symspec] --no-exec-counts[=symspec]
+ Suppress output in the execution count listing.
+ If given without an argument, the listing is
+ suppressed completely. With a "symspec", suppress
+ the selected symbols from the call-graph. If the
+ option is specified multiple times, the union of
+ the selected symbols is suppressed. This option
+ has lower precedence than --exec-counts.
+
+-i --file-info
+ Print information about the profile files that
+ are read. The information consists of the
+ number and types of records present in the
+ profile file. Currently, a profile file can
+ contain any number and any combination of histogram,
+ call-graph, or basic-block count records.
+
+-s --sum
+
+-x --all-lines
+ This option affects annotated source output only.
+ By default, only the lines at the beginning of
+ a basic-block are annotated. If this option is
+ specified, every line in a basic-block is annotated
+ by repeating the annotation for the first line.
+ This option is identical to tcov's "-a".
+
+-I dirs --directory-path=dirs
+ This option affects annotated source output only.
+ Specifies the list of directories to be searched
+ for source files. The argument "dirs" is a colon
+ separated list of directories. By default, gprof
+ searches for source files relative to the current
+ working directory only.
+
+-z --display-unused-functions
+
+-m num --min-count=num
+ This option affects annotated source and execution
+ count output only. Symbols that are executed
+ less than "num" times are suppressed. For annotated
+ source output, suppressed symbols are marked
+ by five hash-marks (#####). In an execution count
+ output, suppressed symbols do not appear at all.
+
+-L --print-path
+ Normally, source filenames are printed with the path
+ component suppressed. With this option, gprof
+ can be forced to print the full pathname of
+ source filenames. The full pathname is determined
+ from symbolic debugging information in the image file
+ and is relative to the directory in which the compiler
+ was invoked.
+
+-y --separate-files
+ This option affects annotated source output only.
+ Normally, gprof prints annotated source files
+ to standard-output. If this option is specified,
+ annotated source for a file named "path/filename"
+ is generated in the file "filename-ann". That is,
+ annotated output is {\em always\/} generated in
+ gprof's current working directory. Care has to
+ be taken if a program consists of files that have
+ identical filenames, but distinct paths.
+
+-c --static-call-graph
+
+-t num --table-length=num
+ This option affects annotated source output only.
+ After annotating a source file, gprof generates
+ an execution count summary consisting of a table
+ of lines with the top execution counts. By
+ default, this table is ten entries long.
+ This option can be used to change the table length
+ or, by specifying an argument value of 0, it can be
+ suppressed completely.
+
+-n symspec --time=symspec
+ Only symbols selected by "symspec" are considered
+ in total and percentage time computations.
+ However, this option does not affect percentage time
+ computation for the flat profile.
+ If the option is specified multiple times, the union
+ of all selected symbols is used in time computations.
+
+-N --no-time=symspec
+ Exclude the symbols selected by "symspec" from
+ total and percentage time computations.
+ However, this option does not affect percentage time
+ computation for the flat profile.
+ This option is ignored if any --time options are
+ specified.
+
+-w num --width=num
+ Sets the output line width. Currently, this option
+ affects the printing of the call-graph function index
+ only.
+
+-e <no long form---for backwards compatibility only>
+-E <no long form---for backwards compatibility only>
+-f <no long form---for backwards compatibility only>
+-F <no long form---for backwards compatibility only>
+-k <no long form---for backwards compatibility only>
+-b --brief
+-dnum --debug[=num]
+
+-h --help
+ Prints a usage message.
+
+-O name --file-format=name
+ Selects the format of the profile data files.
+ Recognized formats are "auto", "bsd", "magic",
+ and "prof". The last one is not yet supported.
+ Format "auto" attempts to detect the file format
+ automatically (this is the default behavior).
+ It attempts to read the profile data files as
+ "magic" files and if this fails, falls back to
+ the "bsd" format. "bsd" forces gprof to read
+ the data files in the BSD format. "magic" forces
+ gprof to read the data files in the "magic" format.
+
+-T --traditional
+-v --version
+
+** File Format Changes
+
+The old BSD-derived format used for profile data does not contain a
+magic cookie that allows to check whether a data file really is a
+gprof file. Furthermore, it does not provide a version number, thus
+rendering changes to the file format almost impossible. GNU gprof
+uses a new file format that provides these features. For backward
+compatibility, GNU gprof continues to support the old BSD-derived
+format, but not all features are supported with it. For example,
+basic-block execution counts cannot be accommodated by the old file
+format.
+
+The new file format is defined in header file \file{gmon_out.h}. It
+consists of a header containing the magic cookie and a version number,
+as well as some spare bytes available for future extensions. All data
+in a profile data file is in the native format of the host on which
+the profile was collected. GNU gprof adapts automatically to the
+byte-order in use.
+
+In the new file format, the header is followed by a sequence of
+records. Currently, there are three different record types: histogram
+records, call-graph arc records, and basic-block execution count
+records. Each file can contain any number of each record type. When
+reading a file, GNU gprof will ensure records of the same type are
+compatible with each other and compute the union of all records. For
+example, for basic-block execution counts, the union is simply the sum
+of all execution counts for each basic-block.
+
+*** Histogram Records
+
+Histogram records consist of a header that is followed by an array of
+bins. The header contains the text-segment range that the histogram
+spans, the size of the histogram in bytes (unlike in the old BSD
+format, this does not include the size of the header), the rate of the
+profiling clock, and the physical dimension that the bin counts
+represent after being scaled by the profiling clock rate. The
+physical dimension is specified in two parts: a long name of up to 15
+characters and a single character abbreviation. For example, a
+histogram representing real-time would specify the long name as
+"seconds" and the abbreviation as "s". This feature is useful for
+architectures that support performance monitor hardware (which,
+fortunately, is becoming increasingly common). For example, under DEC
+OSF/1, the "uprofile" command can be used to produce a histogram of,
+say, instruction cache misses. In this case, the dimension in the
+histogram header could be set to "i-cache misses" and the abbreviation
+could be set to "1" (because it is simply a count, not a physical
+dimension). Also, the profiling rate would have to be set to 1 in
+this case.
+
+Histogram bins are 16-bit numbers and each bin represent an equal
+amount of text-space. For example, if the text-segment is one
+thousand bytes long and if there are ten bins in the histogram, each
+bin represents one hundred bytes.
+
+
+*** Call-Graph Records
+
+Call-graph records have a format that is identical to the one used in
+the BSD-derived file format. It consists of an arc in the call graph
+and a count indicating the number of times the arc was traversed
+during program execution. Arcs are specified by a pair of addresses:
+the first must be within caller's function and the second must be
+within the callee's function. When performing profiling at the
+function level, these addresses can point anywhere within the
+respective function. However, when profiling at the line-level, it is
+better if the addresses are as close to the call-site/entry-point as
+possible. This will ensure that the line-level call-graph is able to
+identify exactly which line of source code performed calls to a
+function.
+
+*** Basic-Block Execution Count Records
+
+Basic-block execution count records consist of a header followed by a
+sequence of address/count pairs. The header simply specifies the
+length of the sequence. In an address/count pair, the address
+identifies a basic-block and the count specifies the number of times
+that basic-block was executed. Any address within the basic-address can
+be used.
+
+IMPLEMENTATION NOTE: gcc -a can be used to instrument a program to
+record basic-block execution counts. However, the __bb_exit_func()
+that is currently present in libgcc2.c does not generate a gmon.out
+file in a suiteable format. This should be fixed for future releases
+of gcc. In the meantime, contact davidm@cs.arizona.edu for a version
+of __bb_exit_func() to is appropriate.

+/* Print a suggested function ordering based on the profiling data.
+
+ We perform 4 major steps when ordering functions:
+
+ * Group unused functions together and place them at the
+ end of the function order.
+
+ * Search the highest use arcs (those which account for 90% of
+ the total arc count) for functions which have several parents.
+
+ Group those with the most call sites together (currently the
+ top 1.25% which have at least five different call sites).
+
+ These are emitted at the start of the function order.
+
+ * Use a greedy placement algorithm to place functions which
+ occur in the top 99% of the arcs in the profile. Some provisions
+ are made to handle high usage arcs where the parent and/or
+ child has already been placed.
+
+ * Run the same greedy placement algorithm on the remaining
+ arcs to place the leftover functions.
+
+
+ The various "magic numbers" should (one day) be tuneable by command
+ line options. They were arrived at by benchmarking a few applications
+ with various values to see which values produced better overall function
+ orderings.
+
+ Of course, profiling errors, machine limitations (PA long calls), and
+ poor cutoff values for the placement algorithm may limit the usefullness
+ of the resulting function order. Improvements would be greatly appreciated.
+
+ Suggestions:
+
+ * Place the functions with many callers near the middle of the
+ list to reduce long calls.
+
+ * Propagate arc usage changes as functions are placed. Ie if
+ func1 and func2 are placed together, arcs to/from those arcs
+ to the same parent/child should be combined, then resort the
+ arcs to choose the next one.
+
+ * Implement some global positioning algorithm to place the
+ chains made by the greedy local positioning algorithm. Probably
+ by examining arcs which haven't been placed yet to tie two
+ chains together.
+
+ * Take a function's size and time into account in the algorithm;
+ size in particular is important on the PA (long calls). Placing
+ many small functions onto their own page may be wise.
+
+ * Use better profiling information; many published algorithms
+ are based on call sequences through time, rather than just
+ arc counts.
+
+ * Prodecure cloning could improve performance when a small number
+ of arcs account for most of the calls to a particular function.
+
+ * Use relocation information to avoid moving unused functions
+ completely out of the code stream; this would avoid severe lossage
+ when the profile data bears little resemblance to actual runs.
+
+ * Propagation of arc usages should also improve .o link line
+ ordering which shares the same arc placement algorithm with
+ the function ordering code (in fact it is a degenerate case
+ of function ordering). */

+ mmap shared fixed at somewhere currently unmapped

+ like early versions of FreeBSD and possibly contemporary NetBSD.)
+ For shared mappings, we should conversely verify that changes get
+ propogated back to all the places they're supposed to be.
+
+ Grep wants private fixed already mapped.
+ The main things grep needs to know about mmap are:
+ * does it exist and is it safe to write into the mmap'd area

+.SH NAME
+gprof \- display call graph profile data
+.SH SYNOPSIS
+.B gprof [ \-abcsz ] [ \-e|\-E
+.I name
+.B ] [ \-f|\-F
+.I name
+.B ]
+.B [ \-k
+.I fromname toname
+.B ] [
+.I objfile
+.B [
+.I gmon.out
+.B ]
+.B ]
+.SH DESCRIPTION
+.B gprof
+produces an execution profile of C, Pascal, or Fortran77 programs.
+The effect of called routines is incorporated in the profile of each caller.
+The profile data is taken from the call graph profile file
+\&(`gmon.out' default) which is created by programs
+that are compiled with the
+.B \-pg
+option of
+.BR cc ( 1 ) ,
+.BR pc ( 1 ) ,
+and
+.BR f77 ( 1 ) .
+The
+.B \-pg
+option also links in versions of the library routines
+that are compiled for profiling.
+.B Gprof
+reads the given object file (the default is `a.out')
+and establishes the relation between its symbol table
+and the call graph profile from `gmon.out'.
+If more than one profile file is specified,
+the
+.B gprof
+output shows the sum of the profile information in the given profile files.
+.PP
+.B Gprof
+calculates the amount of time spent in each routine.
+Next, these times are propagated along the edges of the call graph.
+Cycles are discovered, and calls into a cycle are made to share the time
+of the cycle.
+The first listing shows the functions
+sorted according to the time they represent
+including the time of their call graph descendants.
+Below each function entry is shown its (direct) call graph children,
+and how their times are propagated to this function.
+A similar display above the function shows how this function's time and the
+time of its descendants is propagated to its (direct) call graph parents.
+.PP
+Cycles are also shown, with an entry for the cycle as a whole and
+a listing of the members of the cycle and their contributions to the
+time and call counts of the cycle.
+.PP
+Second, a flat profile is given,
+similar to that provided by
+.BR prof ( 1 ) .
+This listing gives the total execution times, the call counts,
+the time in milliseconds the call spent in the routine itself, and
+the time in milliseconds the call spent in the routine itself including
+its descendants.
+.PP
+Finally, an index of the function names is provided.
+.SH OPTIONS
+The following options are available:
+.TP
+.B \-a
+suppresses the printing of statically declared functions.
+If this option is given, all relevant information about the static function
+(e.g., time samples, calls to other functions, calls from other functions)
+belongs to the function loaded just before the static function in the
+\&`objfile' file.
+.TP
+.B \-b
+suppresses the printing of a description of each field in the profile.
+.TP
+.B \-c
+the static call graph of the program is discovered by a heuristic
+that examines the text space of the object file.
+Static-only parents or children are shown
+with call counts of 0.
+.TP
+.BI "\-e " name
+suppresses the printing of the graph profile entry for routine
+.I name
+and all its descendants
+(unless they have other ancestors that aren't suppressed).
+More than one
+.B \-e
+option may be given.
+Only one
+.I name
+may be given with each
+.B \-e
+option.
+.TP
+.BI "\-E " name
+suppresses the printing of the graph profile entry for routine
+.I name
+(and its descendants) as
+.B \-e ,
+above, and also excludes the time spent in
+.I name
+(and its descendants) from the total and percentage time computations.
+(For example,
+.BI "\-E " mcount
+.BI "\-E " mcleanup
+is the default.)
+.TP
+.BI "\-f " name
+prints the graph profile entry of only the specified routine
+.I name
+and its descendants.
+More than one
+.B \-f
+option may be given.
+Only one
+.I name
+may be given with each
+.B \-f
+option.
+.TP
+.BI "\-F " name
+prints the graph profile entry of only the routine
+.I name
+and its descendants (as
+.B \-f ,
+above) and also uses only the times of the printed routines
+in total time and percentage computations.
+More than one
+.B \-F
+option may be given.
+Only one
+.I name
+may be given with each
+.B \-F
+option.
+The
+.B \-F
+option
+overrides
+the
+.B \-E
+option.
+.TP
+.BI "\-k " "fromname toname"
+will delete any arcs from routine
+.I fromname
+to routine
+.IR toname .
+This can be used to break undesired cycles.
+More than one
+.B \-k
+option may be given.
+Only one pair of routine names may be given with each
+.B \-k
+option.
+.TP
+.B \-s
+a profile file `gmon.sum' is produced that represents
+the sum of the profile information in all the specified profile files.
+This summary profile file may be given to later
+executions of gprof (probably also with a
+.BR \-s )
+to accumulate profile data across several runs of an `objfile' file.
+.TP
+.B -v
+prints the version number for gprof, and then exits.
+.TP
+.B -z
+displays routines that have zero usage (as shown by call counts
+and accumulated time).
+This is useful with the
+.B \-c
+option for discovering which routines were never called.
+.PP
+.SH FILES
+.ta \w'gmon.sum 'u
+a.out the namelist and text space.
+.br
+gmon.out dynamic call graph and profile.
+.br
+gmon.sum summarized dynamic call graph and profile.

+.SH HISTORY
+.B Gprof
+appeared in 4.2 BSD.
+.SH BUGS
+The granularity of the sampling is shown, but remains
+statistical at best.
+We assume that the time for each execution of a function
+can be expressed by the total time for the function divided
+by the number of times the function is called.
+Thus the time propagated along the call graph arcs to the function's
+parents is directly proportional to the number of times that
+arc is traversed.
+.PP
+Parents that are not themselves profiled will have the time of
+their profiled children propagated to them, but they will appear
+to be spontaneously invoked in the call graph listing, and will
+not have their time propagated further.
+Similarly, signal catchers, even though profiled, will appear
+to be spontaneous (although for more obscure reasons).
+Any profiled children of signal catchers should have their times
+propagated properly, unless the signal catcher was invoked during
+the execution of the profiling routine, in which case all is lost.
+.PP
+The profiled program must call
+.BR exit ( 2 )
+or return normally for the profiling information to be saved
+in the `gmon.out' file.

+@node Introduction
+@chapter Introduction to Profiling
+
+Profiling allows you to learn where your program spent its time and which
+functions called which other functions while it was executing. This
+information can show you which pieces of your program are slower than you
+expected, and might be candidates for rewriting to make your program
+execute faster. It can also tell you which functions are being called more
+or less often than you expected. This may help you spot bugs that had
+otherwise been unnoticed.
+
+Since the profiler uses information collected during the actual execution
+of your program, it can be used on programs that are too large or too
+complex to analyze by reading the source. However, how your program is run
+will affect the information that shows up in the profile data. If you
+don't use some feature of your program while it is being profiled, no
+profile information will be generated for that feature.
+
+Profiling has several steps:
+
+@itemize @bullet
+@item
+You must compile and link your program with profiling enabled.
+@xref{Compiling}.
+
+@item
+You must execute your program to generate a profile data file.
+@xref{Executing}.
+
+@item
+You must run @code{gprof} to analyze the profile data.
+@xref{Invoking}.
+@end itemize
+
+The next three chapters explain these steps in greater detail.
+
+Several forms of output are available from the analysis.
+
+The @dfn{flat profile} shows how much time your program spent in each function,
+and how many times that function was called. If you simply want to know
+which functions burn most of the cycles, it is stated concisely here.
+@xref{Flat Profile}.
+
+The @dfn{call graph} shows, for each function, which functions called it, which
+other functions it called, and how many times. There is also an estimate
+of how much time was spent in the subroutines of each function. This can
+suggest places where you might try to eliminate function calls that use a
+lot of time. @xref{Call Graph}.
+
+The @dfn{annotated source} listing is a copy of the program's
+source code, labeled with the number of times each line of the
+program was executed. @xref{Annotated Source}.
+
+To better understand how profiling works, you may wish to read
+a description of its implementation.
+@xref{Implementation}.
+
+@node Compiling
+@chapter Compiling a Program for Profiling
+
+The first step in generating profile information for your program is
+to compile and link it with profiling enabled.
+
+To compile a source file for profiling, specify the @samp{-pg} option when
+you run the compiler. (This is in addition to the options you normally
+use.)
+
+To link the program for profiling, if you use a compiler such as @code{cc}
+to do the linking, simply specify @samp{-pg} in addition to your usual
+options. The same option, @samp{-pg}, alters either compilation or linking
+to do what is necessary for profiling. Here are examples:
+
+@example
+cc -g -c myprog.c utils.c -pg
+cc -o myprog myprog.o utils.o -pg
+@end example
+
+The @samp{-pg} option also works with a command that both compiles and links:
+
+@example
+cc -o myprog myprog.c utils.c -g -pg
+@end example
+
+If you run the linker @code{ld} directly instead of through a compiler
+such as @code{cc}, you may have to specify a profiling startup file
+@file{gcrt0.o} as the first input file instead of the usual startup
+file @file{crt0.o}. In addition, you would probably want to
+specify the profiling C library, @file{libc_p.a}, by writing
+@samp{-lc_p} instead of the usual @samp{-lc}. This is not absolutely
+necessary, but doing this gives you number-of-calls information for
+standard library functions such as @code{read} and @code{open}. For
+example:
+
+@example
+ld -o myprog /lib/gcrt0.o myprog.o utils.o -lc_p
+@end example
+
+If you compile only some of the modules of the program with @samp{-pg}, you
+can still profile the program, but you won't get complete information about
+the modules that were compiled without @samp{-pg}. The only information
+you get for the functions in those modules is the total time spent in them;
+there is no record of how many times they were called, or from where. This
+will not affect the flat profile (except that the @code{calls} field for
+the functions will be blank), but will greatly reduce the usefulness of the
+call graph.
+
+If you wish to perform line-by-line profiling,
+you will also need to specify the @samp{-g} option,
+instructing the compiler to insert debugging symbols into the program
+that match program addresses to source code lines.
+@xref{Line-by-line}.
+
+In addition to the @samp{-pg} and @samp{-g} options,
+you may also wish to specify the @samp{-a} option when compiling.
+This will instrument
+the program to perform basic-block counting. As the program runs,
+it will count how many times it executed each branch of each @samp{if}
+statement, each iteration of each @samp{do} loop, etc. This will
+enable @code{gprof} to construct an annotated source code
+listing showing how many times each line of code was executed.
+
+@node Executing
+@chapter Executing the Program
+
+Once the program is compiled for profiling, you must run it in order to
+generate the information that @code{gprof} needs. Simply run the program
+as usual, using the normal arguments, file names, etc. The program should
+run normally, producing the same output as usual. It will, however, run
+somewhat slower than normal because of the time spent collecting and the
+writing the profile data.
+
+The way you run the program---the arguments and input that you give
+it---may have a dramatic effect on what the profile information shows. The
+profile data will describe the parts of the program that were activated for
+the particular input you use. For example, if the first command you give
+to your program is to quit, the profile data will show the time used in
+initialization and in cleanup, but not much else.
+
+Your program will write the profile data into a file called @file{gmon.out}
+just before exiting. If there is already a file called @file{gmon.out},
+its contents are overwritten. There is currently no way to tell the
+program to write the profile data under a different name, but you can rename
+the file afterward if you are concerned that it may be overwritten.
+
+In order to write the @file{gmon.out} file properly, your program must exit
+normally: by returning from @code{main} or by calling @code{exit}. Calling
+the low-level function @code{_exit} does not write the profile data, and
+neither does abnormal termination due to an unhandled signal.
+
+The @file{gmon.out} file is written in the program's @emph{current working
+directory} at the time it exits. This means that if your program calls
+@code{chdir}, the @file{gmon.out} file will be left in the last directory
+your program @code{chdir}'d to. If you don't have permission to write in
+this directory, the file is not written, and you will get an error message.
+
+Older versions of the @sc{gnu} profiling library may also write a file
+called @file{bb.out}. This file, if present, contains an human-readable
+listing of the basic-block execution counts. Unfortunately, the
+appearance of a human-readable @file{bb.out} means the basic-block
+counts didn't get written into @file{gmon.out}.
+The Perl script @code{bbconv.pl}, included with the @code{gprof}
+source distribution, will convert a @file{bb.out} file into
+a format readable by @code{gprof}.
+
+@node Invoking
+@chapter @code{gprof} Command Summary
+
+After you have a profile data file @file{gmon.out}, you can run @code{gprof}
+to interpret the information in it. The @code{gprof} program prints a
+flat profile and a call graph on standard output. Typically you would
+redirect the output of @code{gprof} into a file with @samp{>}.
+
+You run @code{gprof} like this:
+
+@smallexample
+gprof @var{options} [@var{executable-file} [@var{profile-data-files}@dots{}]] [> @var{outfile}]
+@end smallexample
+
+@noindent
+Here square-brackets indicate optional arguments.
+
+If you omit the executable file name, the file @file{a.out} is used. If
+you give no profile data file name, the file @file{gmon.out} is used. If
+any file is not in the proper format, or if the profile data file does not
+appear to belong to the executable file, an error message is printed.
+
+You can give more than one profile data file by entering all their names
+after the executable file name; then the statistics in all the data files
+are summed together.
+
+The order of these options does not matter.

+
+@item -b
+@itemx --brief
+If the @samp{-b} option is given, @code{gprof} doesn't print the

+are tired of seeing the blurbs.
+
+@item -C[@var{symspec}]
+@itemx --exec-counts[=@var{symspec}]
+The @samp{-C} option causes @code{gprof} to
+print a tally of functions and the number of times each was called.
+If @var{symspec} is specified, print tally only for matching symbols.
+
+If the profile data file contains basic-block count records, specifing
+the @samp{-l} option, along with @samp{-C}, will cause basic-block
+execution counts to be tallied and displayed.
+
+@item -i
+@itemx --file-info
+The @samp{-i} option causes @code{gprof} to display summary information
+about the profile data file(s) and then exit. The number of histogram,
+call graph, and basic-block count records is displayed.
+
+@item -I @var{dirs}
+@itemx --directory-path=@var{dirs}
+The @samp{-I} option specifies a list of search directories in
+which to find source files. Environment variable @var{GPROF_PATH}
+can also be used to convery this information.
+Used mostly for annotated source output.
+
+@item -J[@var{symspec}]
+@itemx --no-annotated-source[=@var{symspec}]
+The @samp{-J} option causes @code{gprof} not to

+If @var{symspec} is specified, @code{gprof} prints annotated source,
+but excludes matching symbols.
+
+@item -L
+@itemx --print-path
+Normally, source filenames are printed with the path

+to print the full pathname of
+source filenames, which is determined
+from symbolic debugging information in the image file
+and is relative to the directory in which the compiler
+was invoked.
+
+@item -p[@var{symspec}]
+@itemx --flat-profile[=@var{symspec}]
+The @samp{-p} option causes @code{gprof} to print a flat profile.
+If @var{symspec} is specified, print flat profile only for matching symbols.
+@xref{Flat Profile}.
+
+@item -P[@var{symspec}]
+@itemx --no-flat-profile[=@var{symspec}]
+The @samp{-P} option causes @code{gprof} to suppress printing a flat profile.
+If @var{symspec} is specified, @code{gprof} prints a flat profile,
+but excludes matching symbols.
+
+@item -q[@var{symspec}]
+@itemx --graph[=@var{symspec}]
+The @samp{-q} option causes @code{gprof} to print the call graph analysis.
+If @var{symspec} is specified, print call graph only for matching symbols
+and their children.
+@xref{Call Graph}.
+
+@item -Q[@var{symspec}]
+@itemx --no-graph[=@var{symspec}]
+The @samp{-Q} option causes @code{gprof} to suppress printing the

+If @var{symspec} is specified, @code{gprof} prints a call graph,
+but excludes matching symbols.
+
+@item -y
+@itemx --separate-files
+This option affects annotated source output only.
+Normally, gprof prints annotated source files
+to standard-output. If this option is specified,
+annotated source for a file named @file{path/filename}
+is generated in the file @file{filename-ann}.
+
+@item -Z[@var{symspec}]
+@itemx --no-exec-counts[=@var{symspec}]
+The @samp{-Z} option causes @code{gprof} not to
+print a tally of functions and the number of times each was called.
+If @var{symspec} is specified, print tally, but exclude matching symbols.
+
+@item --function-ordering
+The @samp{--function-ordering} option causes @code{gprof} to print a
+suggested function ordering for the program based on profiling data.
+This option suggests an ordering which may improve paging, tlb and
+cache behavior for the program on systems which support arbitrary
+ordering of functions in an executable.
+
+The exact details of how to force the linker to place functions
+in a particular order is system dependent and out of the scope of this
+manual.
+
+@item --file-ordering @var{map_file}
+The @samp{--file-ordering} option causes @code{gprof} to print a
+suggested .o link line ordering for the program based on profiling data.
+This option suggests an ordering which may improve paging, tlb and
+cache behavior for the program on systems which do not support arbitrary
+ordering of functions in an executable.
+
+Use of the @samp{-a} argument is highly recommended with this option.
+
+The @var{map_file} argument is a pathname to a file which provides
+function name to object file mappings. The format of the file is similar to
+the output of the program @code{nm}.

+The @samp{-a} option causes @code{gprof} to suppress the printing of
+statically declared (private) functions. (These are functions whose
+names are not listed as global, and which are not visible outside the
+file/function/block where they were defined.) Time spent in these
+functions, calls to/from them, etc, will all be attributed to the

+This option affects both the flat profile and the call graph.
+
+@item -c
+@itemx --static-call-graph
+The @samp{-c} option causes the call graph of the program to be
+augmented by a heuristic which examines the text space of the object
+file and identifies function calls in the binary machine code.
+Since normal call graph records are only generated when functions are
+entered, this option identifies children that could have been called,
+but never were. Calls to functions that were not compiled with
+profiling enabled are also identified, but only if symbol table
+entries are present for them.
+Calls to dynamic library routines are typically @emph{not} found
+by this option.
+Parents or children identified via this heuristic
+are indicated in the call graph with call counts of @samp{0}.
+
+@item -D
+@itemx --ignore-non-functions
+The @samp{-D} option causes @code{gprof} to ignore symbols which
+are not known to be functions. This option will give more accurate
+profile data on systems where it is supported (Solaris and HPUX for
+example).
+
+@item -k @var{from}/@var{to}

+
+@item -l
+@itemx --line
+The @samp{-l} option enables line-by-line profiling, which causes
+histogram hits to be charged to individual source code lines,
+instead of functions.
+If the program was compiled with basic-block counting enabled,
+this option will also identify how many times each line of
+code was executed.
+While line-by-line profiling can help isolate where in a large function
+a program is spending its time, it also significantly increases
+the running time of @code{gprof}, and magnifies statistical
+inaccuracies.

+@end example
+
+Here are some sample symspecs:
+
+@table @samp
+@item main.c
+Selects everything in file @file{main.c}---the
+dot in the string tells gprof to interpret
+the string as a filename, rather than as
+a function name. To select a file whose
+name does not contain a dot, a trailing colon
+should be specified. For example, @samp{odd:} is
+interpreted as the file named @file{odd}.
+
+@item main
+Selects all functions named @samp{main}.
+
+Note that there may be multiple instances of the same function name
+because some of the definitions may be local (i.e., static). Unless a
+function name is unique in a program, you must use the colon notation
+explained below to specify a function from a specific source file.
+
+Sometimes, function names contain dots. In such cases, it is necessar
+to add a leading colon to the name. For example, @samp{:.mul} selects
+function @samp{.mul}.
+
+In some object file formats, symbols have a leading underscore. gprof
+will normally not print these underscores. However, you must use the
+underscore when you name a symbol in a symspec. You can use the
+@code{nm} program to see whether symbols have underscores for the object
+file format you are using.

+The functions are sorted by first by decreasing run-time spent in them,
+then by decreasing number of calls, then alphabetically by name. The
+functions @samp{mcount} and @samp{profil} are part of the profiling
+aparatus and appear in every flat profile; their time gives a measure of
+the amount of overhead due to profiling.
+
+Just before the column headers, a statement appears indicating
+how much time each sample counted as.
+This @dfn{sampling period} estimates the margin of error in each of the time
+figures. A time figure that is not much larger than this is not
+reliable. In this example, each sample counted as 0.01 seconds,
+suggesting a 100 Hz sampling rate.
+The program's total execution time was 0.06
+seconds, as indicated by the @samp{cumulative seconds} field. Since
+each sample counted for 0.01 seconds, this means only six samples
+were taken during the run. Two of the samples occured while the
+program was in the @samp{open} function, as indicated by the
+@samp{self seconds} field. Each of the other four samples
+occured one each in @samp{offtime}, @samp{memccpy}, @samp{write},
+and @samp{mcount}.
+Since only six samples were taken, none of these values can
+be regarded as particularly reliable.
+In another run,
+the @samp{self seconds} field for
+@samp{mcount} might well be @samp{0.00} or @samp{0.02}.
+@xref{Sampling Error}, for a complete discussion.
+
+The remaining functions in the listing (those whose
+@samp{self seconds} field is @samp{0.00}) didn't appear
+in the histogram samples at all. However, the call graph
+indicated that they were called, so therefore they are listed,
+sorted in decreasing order by the @samp{calls} field.
+Clearly some time was spent executing these functions,
+but the paucity of histogram samples prevents any
+determination of how much time each took.
+
+Here is what the fields in each line mean:
+
+@table @code
+@item % time
+This is the percentage of the total execution time your program spent
+in this function. These should all add up to 100%.
+
+@item cumulative seconds
+This is the cumulative total number of seconds the computer spent
+executing this functions, plus the time spent in all the functions
+above this one in this table.
+
+@item self seconds
+This is the number of seconds accounted for by this function alone.
+The flat profile listing is sorted first by this number.
+
+@item calls
+This is the total number of times the function was called. If the
+function was never called, or the number of times it was called cannot
+be determined (probably because the function was not compiled with
+profiling enabled), the @dfn{calls} field is blank.
+
+@item self ms/call
+This represents the average number of milliseconds spent in this
+function per call, if this function is profiled. Otherwise, this field
+is blank for this function.
+
+@item total ms/call
+This represents the average number of milliseconds spent in this
+function and its descendants per call, if this function is profiled.
+Otherwise, this field is blank for this function.
+This is the only field in the flat profile that uses call graph analysis.

+@subsection How Mutually Recursive Functions Are Described
+@cindex cycle
+@cindex recursion cycle
+
+The graph may be complicated by the presence of @dfn{cycles of
+recursion} in the call graph. A cycle exists if a function calls
+another function that (directly or indirectly) calls (or appears to
+call) the original function. For example: if @code{a} calls @code{b},
+and @code{b} calls @code{a}, then @code{a} and @code{b} form a cycle.
+
+Whenever there are call paths both ways between a pair of functions, they
+belong to the same cycle. If @code{a} and @code{b} call each other and
+@code{b} and @code{c} call each other, all three make one cycle. Note that
+even if @code{b} only calls @code{a} if it was not called from @code{a},
+@code{gprof} cannot determine this, so @code{a} and @code{b} are still
+considered a cycle.
+
+The cycles are numbered with consecutive integers. When a function
+belongs to a cycle, each time the function name appears in the call graph
+it is followed by @samp{<cycle @var{number}>}.
+
+The reason cycles matter is that they make the time values in the call
+graph paradoxical. The ``time spent in children'' of @code{a} should
+include the time spent in its subroutine @code{b} and in @code{b}'s
+subroutines---but one of @code{b}'s subroutines is @code{a}! How much of
+@code{a}'s time should be included in the children of @code{a}, when
+@code{a} is indirectly recursive?
+
+The way @code{gprof} resolves this paradox is by creating a single entry
+for the cycle as a whole. The primary line of this entry describes the
+total time spent directly in the functions of the cycle. The
+``subroutines'' of the cycle are the individual functions of the cycle, and
+all other functions that were called directly by them. The ``callers'' of
+the cycle are the functions, outside the cycle, that called functions in
+the cycle.
+
+Here is an example portion of a call graph which shows a cycle containing
+functions @code{a} and @code{b}. The cycle was entered by a call to
+@code{a} from @code{main}; both @code{a} and @code{b} called @code{c}.

+
+The @code{self} field of the cycle's primary line is the total time
+spent in all the functions of the cycle. It equals the sum of the
+@code{self} fields for the individual functions in the cycle, found
+in the entry in the subroutine lines for these functions.
+
+The @code{children} fields of the cycle's primary line and subroutine lines
+count only subroutines outside the cycle. Even though @code{a} calls
+@code{b}, the time spent in those calls to @code{b} is not counted in
+@code{a}'s @code{children} time. Thus, we do not encounter the problem of
+what to do when the time in those calls to @code{b} includes indirect
+recursive calls back to @code{a}.
+
+The @code{children} field of a caller-line in the cycle's entry estimates
+the amount of time spent @emph{in the whole cycle}, and its other
+subroutines, on the times when that caller called a function in the cycle.
+
+The @code{calls} field in the primary line for the cycle has two numbers:
+first, the number of times functions in the cycle were called by functions
+outside the cycle; second, the number of times they were called by
+functions in the cycle (including times when a function in the cycle calls
+itself). This is a generalization of the usual split into nonrecursive and
+recursive calls.
+
+The @code{calls} field of a subroutine-line for a cycle member in the
+cycle's entry says how many time that function was called from functions in
+the cycle. The total of all these is the second number in the primary line's
+@code{calls} field.
+
+In the individual entry for a function in a cycle, the other functions in
+the same cycle can appear as subroutines and as callers. These lines show
+how many times each function in the cycle called or was called from each other
+function in the cycle. The @code{self} and @code{children} fields in these
+lines are blank because of the difficulty of defining meanings for them
+when recursion is going on.

+@code{gprof}'s @samp{-l} option causes the program to perform

+@section The Annotated Source Listing
+
+@code{gprof}'s @samp{-A} option triggers an annotated source listing,
+which lists the program's source code, each function labeled with the
+number of times it was called. You may also need to specify the
+@samp{-I} option, if @code{gprof} can't find the source code files.
+
+Compiling with @samp{gcc @dots{} -g -pg -a} augments your program
+with basic-block counting code, in addition to function counting code.
+This enables @code{gprof} to determine how many times each line
+of code was exeucted.
+For example, consider the following function, taken from gzip,
+with line numbers added:
+
+@smallexample
+ 1 ulg updcrc(s, n)
+ 2 uch *s;
+ 3 unsigned n;
+ 4 @{
+ 5 register ulg c;
+ 6
+ 7 static ulg crc = (ulg)0xffffffffL;
+ 8
+ 9 if (s == NULL) @{
+10 c = 0xffffffffL;
+11 @} else @{
+12 c = crc;
+13 if (n) do @{
+14 c = crc_32_tab[...];
+15 @} while (--n);
+16 @}
+17 crc = c;
+18 return c ^ 0xffffffffL;
+19 @}
+
+@end smallexample
+
+@code{updcrc} has at least five basic-blocks.
+One is the function itself. The
+@code{if} statement on line 9 generates two more basic-blocks, one
+for each branch of the @code{if}. A fourth basic-block results from
+the @code{if} on line 13, and the contents of the @code{do} loop form
+the fifth basic-block. The compiler may also generate additional
+basic-blocks to handle various special cases.
+
+A program augmented for basic-block counting can be analyzed with
+@code{gprof -l -A}. I also suggest use of the @samp{-x} option,
+which ensures that each line of code is labeled at least once.
+Here is @code{updcrc}'s
+annotated source listing for a sample @code{gzip} run:
+
+@smallexample
+ ulg updcrc(s, n)
+ uch *s;
+ unsigned n;
+ 2 ->@{
+ register ulg c;
+
+ static ulg crc = (ulg)0xffffffffL;
+
+ 2 -> if (s == NULL) @{
+ 1 -> c = 0xffffffffL;
+ 1 -> @} else @{
+ 1 -> c = crc;
+ 1 -> if (n) do @{
+ 26312 -> c = crc_32_tab[...];
+26312,1,26311 -> @} while (--n);
+ @}
+ 2 -> crc = c;
+ 2 -> return c ^ 0xffffffffL;
+ 2 ->@}
+@end smallexample
+
+In this example, the function was called twice, passing once through
+each branch of the @code{if} statement. The body of the @code{do}
+loop was executed a total of 26312 times. Note how the @code{while}
+statement is annotated. It began execution 26312 times, once for
+each iteration through the loop. One of those times (the last time)
+it exited, while it branched back to the beginning of the loop 26311 times.

+
+@node Sampling Error,Assumptions,,Inaccuracy
+@section Statistical Sampling Error
+
+The run-time figures that @code{gprof} gives you are based on a sampling
+process, so they are subject to statistical inaccuracy. If a function runs
+only a small amount of time, so that on the average the sampling process
+ought to catch that function in the act only once, there is a pretty good
+chance it will actually find that function zero times, or twice.
+
+By contrast, the number-of-calls and basic-block figures
+are derived by counting, not
+sampling. They are completely accurate and will not vary from run to run
+if your program is deterministic.
+
+The @dfn{sampling period} that is printed at the beginning of the flat
+profile says how often samples are taken. The rule of thumb is that a
+run-time figure is accurate if it is considerably bigger than the sampling
+period.
+
+The actual amount of error can be predicted.
+For @var{n} samples, the @emph{expected} error
+is the square-root of @var{n}. For example,
+if the sampling period is 0.01 seconds and @code{foo}'s run-time is 1 second,
+@var{n} is 100 samples (1 second/0.01 seconds), sqrt(@var{n}) is 10 samples, so
+the expected error in @code{foo}'s run-time is 0.1 seconds (10*0.01 seconds),
+or ten percent of the observed value.
+Again, if the sampling period is 0.01 seconds and @code{bar}'s run-time is
+100 seconds, @var{n} is 10000 samples, sqrt(@var{n}) is 100 samples, so
+the expected error in @code{bar}'s run-time is 1 second,
+or one percent of the observed value.
+It is likely to
+vary this much @emph{on the average} from one profiling run to the next.
+(@emph{Sometimes} it will vary more.)
+
+This does not mean that a small run-time figure is devoid of information.
+If the program's @emph{total} run-time is large, a small run-time for one
+function does tell you that that function used an insignificant fraction of
+the whole program's time. Usually this means it is not worth optimizing.
+
+One way to get more accuracy is to give your program more (but similar)
+input data so it will take longer. Another way is to combine the data from
+several runs, using the @samp{-s} option of @code{gprof}. Here is how:
+
+@enumerate
+@item
+Run your program once.
+
+@item
+Issue the command @samp{mv gmon.out gmon.sum}.
+
+@item
+Run your program again, the same as before.
+

+Merge the new data in @file{gmon.out} into @file{gmon.sum} with this command:
+
+@example
+gprof -s @var{executable-file} gmon.out gmon.sum
+@end example
+
+@item
+Repeat the last two steps as often as you wish.
+

+@end enumerate
+
+@node Assumptions,,Sampling Error,Inaccuracy
+@section Estimating @code{children} Times
+
+Some of the figures in the call graph are estimates---for example, the
+@code{children} time values and all the the time figures in caller and
+subroutine lines.
+
+There is no direct information about these measurements in the profile
+data itself. Instead, @code{gprof} estimates them by making an assumption
+about your program that might or might not be true.
+
+The assumption made is that the average time spent in each call to any
+function @code{foo} is not correlated with who called @code{foo}. If
+@code{foo} used 5 seconds in all, and 2/5 of the calls to @code{foo} came
+from @code{a}, then @code{foo} contributes 2 seconds to @code{a}'s
+@code{children} time, by assumption.
+
+This assumption is usually true enough, but for some programs it is far
+from true. Suppose that @code{foo} returns very quickly when its argument
+is zero; suppose that @code{a} always passes zero as an argument, while
+other callers of @code{foo} pass other arguments. In this program, all the
+time spent in @code{foo} is in the calls from callers other than @code{a}.
+But @code{gprof} has no way of knowing this; it will blindly and
+incorrectly charge 2 seconds of time in @code{foo} to the children of
+@code{a}.
+
+@c FIXME - has this been fixed?
+We hope some day to put more complete data into @file{gmon.out}, so that
+this assumption is no longer needed, if we can figure out how. For the
+nonce, the estimated figures are usually more useful than misleading.

+@section Implementation of Profiling
+
+Profiling works by changing how every function in your program is compiled
+so that when it is called, it will stash away some information about where
+it was called from. From this, the profiler can figure out what function
+called it, and can count how many times it was called. This change is made
+by the compiler when your program is compiled with the @samp{-pg} option,
+which causes every function to call @code{mcount}
+(or @code{_mcount}, or @code{__mcount}, depending on the OS and compiler)
+as one of its first operations.
+
+The @code{mcount} routine, included in the profiling library,
+is responsible for recording in an in-memory call graph table
+both its parent routine (the child) and its parent's parent. This is
+typically done by examining the stack frame to find both
+the address of the child, and the return address in the original parent.
+Since this is a very machine-dependant operation, @code{mcount}
+itself is typically a short assembly-language stub routine
+that extracts the required
+information, and then calls @code{__mcount_internal}
+(a normal C function) with two arguments - @code{frompc} and @code{selfpc}.
+@code{__mcount_internal} is responsible for maintaining
+the in-memory call graph, which records @code{frompc}, @code{selfpc},
+and the number of times each of these call arcs was transversed.
+
+GCC Version 2 provides a magical function (@code{__builtin_return_address}),
+which allows a generic @code{mcount} function to extract the
+required information from the stack frame. However, on some
+architectures, most notably the SPARC, using this builtin can be
+very computationally expensive, and an assembly language version
+of @code{mcount} is used for performance reasons.
+
+Number-of-calls information for library routines is collected by using a
+special version of the C library. The programs in it are the same as in
+the usual C library, but they were compiled with @samp{-pg}. If you
+link your program with @samp{gcc @dots{} -pg}, it automatically uses the
+profiling version of the library.
+
+Profiling also involves watching your program as it runs, and keeping a
+histogram of where the program counter happens to be every now and then.
+Typically the program counter is looked at around 100 times per second of
+run time, but the exact frequency may vary from system to system.
+
+This is done is one of two ways. Most UNIX-like operating systems
+provide a @code{profil()} system call, which registers a memory
+array with the kernel, along with a scale
+factor that determines how the program's address space maps
+into the array.
+Typical scaling values cause every 2 to 8 bytes of address space
+to map into a single array slot.
+On every tick of the system clock
+(assuming the profiled program is running), the value of the
+program counter is examined and the corresponding slot in
+the memory array is incremented. Since this is done in the kernel,
+which had to interrupt the process anyway to handle the clock
+interrupt, very little additional system overhead is required.
+
+However, some operating systems, most notably Linux 2.0 (and earlier),
+do not provide a @code{profil()} system call. On such a system,
+arrangements are made for the kernel to periodically deliver
+a signal to the process (typically via @code{setitimer()}),
+which then performs the same operation of examining the
+program counter and incrementing a slot in the memory array.
+Since this method requires a signal to be delivered to
+user space every time a sample is taken, it uses considerably
+more overhead than kernel-based profiling. Also, due to the
+added delay required to deliver the signal, this method is
+less accurate as well.
+
+A special startup routine allocates memory for the histogram and
+either calls @code{profil()} or sets up
+a clock signal handler.
+This routine (@code{monstartup}) can be invoked in several ways.
+On Linux systems, a special profiling startup file @code{gcrt0.o},
+which invokes @code{monstartup} before @code{main},
+is used instead of the default @code{crt0.o}.
+Use of this special startup file is one of the effects
+of using @samp{gcc @dots{} -pg} to link.
+On SPARC systems, no special startup files are used.
+Rather, the @code{mcount} routine, when it is invoked for
+the first time (typically when @code{main} is called),
+calls @code{monstartup}.
+
+If the compiler's @samp{-a} option was used, basic-block counting
+is also enabled. Each object file is then compiled with a static array
+of counts, initially zero.
+In the executable code, every time a new basic-block begins
+(i.e. when an @code{if} statement appears), an extra instruction
+is inserted to increment the corresponding count in the array.
+At compile time, a paired array was constructed that recorded
+the starting address of each basic-block. Taken together,
+the two arrays record the starting address of every basic-block,
+along with the number of times it was executed.
+
+The profiling library also includes a function (@code{mcleanup}) which is
+typically registered using @code{atexit()} to be called as the
+program exits, and is responsible for writing the file @file{gmon.out}.
+Profiling is turned off, various headers are output, and the histogram
+is written, followed by the call-graph arcs and the basic-block counts.
+
+The output from @code{gprof} gives no indication of parts of your program that
+are limited by I/O or swapping bandwidth. This is because samples of the
+program counter are taken at fixed intervals of the program's run time.
+Therefore, the
+time measurements in @code{gprof} output say nothing about time that your
+program was not running. For example, a part of the program that creates
+so much data that it cannot all fit in physical memory at once may run very
+slowly due to thrashing, but @code{gprof} will say it uses little time. On
+the other hand, sampling by run time has the advantage that the amount of
+load due to other users won't directly affect the output you get.
+
+@node File Format,Internals,Implementation,Details
+@section Profiling Data File Format
+
+The old BSD-derived file format used for profile data does not contain a
+magic cookie that allows to check whether a data file really is a
+gprof file. Furthermore, it does not provide a version number, thus
+rendering changes to the file format almost impossible. @sc{gnu} @code{gprof}
+uses a new file format that provides these features. For backward
+compatibility, @sc{gnu} @code{gprof} continues to support the old BSD-derived
+format, but not all features are supported with it. For example,
+basic-block execution counts cannot be accommodated by the old file
+format.
+
+The new file format is defined in header file @file{gmon_out.h}. It
+consists of a header containing the magic cookie and a version number,
+as well as some spare bytes available for future extensions. All data
+in a profile data file is in the native format of the host on which
+the profile was collected. @sc{gnu} @code{gprof} adapts automatically to the
+byte-order in use.
+
+In the new file format, the header is followed by a sequence of
+records. Currently, there are three different record types: histogram
+records, call-graph arc records, and basic-block execution count
+records. Each file can contain any number of each record type. When
+reading a file, @sc{gnu} @code{gprof} will ensure records of the same type are
+compatible with each other and compute the union of all records. For
+example, for basic-block execution counts, the union is simply the sum
+of all execution counts for each basic-block.
+
+@subsection Histogram Records
+
+Histogram records consist of a header that is followed by an array of
+bins. The header contains the text-segment range that the histogram
+spans, the size of the histogram in bytes (unlike in the old BSD
+format, this does not include the size of the header), the rate of the
+profiling clock, and the physical dimension that the bin counts
+represent after being scaled by the profiling clock rate. The
+physical dimension is specified in two parts: a long name of up to 15
+characters and a single character abbreviation. For example, a
+histogram representing real-time would specify the long name as
+"seconds" and the abbreviation as "s". This feature is useful for
+architectures that support performance monitor hardware (which,
+fortunately, is becoming increasingly common). For example, under DEC
+OSF/1, the "uprofile" command can be used to produce a histogram of,
+say, instruction cache misses. In this case, the dimension in the
+histogram header could be set to "i-cache misses" and the abbreviation
+could be set to "1" (because it is simply a count, not a physical
+dimension). Also, the profiling rate would have to be set to 1 in
+this case.
+
+Histogram bins are 16-bit numbers and each bin represent an equal
+amount of text-space. For example, if the text-segment is one
+thousand bytes long and if there are ten bins in the histogram, each
+bin represents one hundred bytes.
+
+
+@subsection Call-Graph Records
+
+Call-graph records have a format that is identical to the one used in
+the BSD-derived file format. It consists of an arc in the call graph
+and a count indicating the number of times the arc was traversed
+during program execution. Arcs are specified by a pair of addresses:
+the first must be within caller's function and the second must be
+within the callee's function. When performing profiling at the
+function level, these addresses can point anywhere within the
+respective function. However, when profiling at the line-level, it is
+better if the addresses are as close to the call-site/entry-point as
+possible. This will ensure that the line-level call-graph is able to
+identify exactly which line of source code performed calls to a
+function.
+
+@subsection Basic-Block Execution Count Records
+
+Basic-block execution count records consist of a header followed by a
+sequence of address/count pairs. The header simply specifies the
+length of the sequence. In an address/count pair, the address
+identifies a basic-block and the count specifies the number of times
+that basic-block was executed. Any address within the basic-address can
+be used.
+
+@node Internals,Debugging,File Format,Details
+@section @code{gprof}'s Internal Operation
+
+Like most programs, @code{gprof} begins by processing its options.
+During this stage, it may building its symspec list
+(@code{sym_ids.c:sym_id_add}), if
+options are specified which use symspecs.
+@code{gprof} maintains a single linked list of symspecs,
+which will eventually get turned into 12 symbol tables,
+organized into six include/exclude pairs - one
+pair each for the flat profile (INCL_FLAT/EXCL_FLAT),
+the call graph arcs (INCL_ARCS/EXCL_ARCS),
+printing in the call graph (INCL_GRAPH/EXCL_GRAPH),
+timing propagation in the call graph (INCL_TIME/EXCL_TIME),
+the annotated source listing (INCL_ANNO/EXCL_ANNO),
+and the execution count listing (INCL_EXEC/EXCL_EXEC).
+
+After option processing, @code{gprof} finishes
+building the symspec list by adding all the symspecs in
+@code{default_excluded_list} to the exclude lists
+EXCL_TIME and EXCL_GRAPH, and if line-by-line profiling is specified,
+EXCL_FLAT as well.
+These default excludes are not added to EXCL_ANNO, EXCL_ARCS, and EXCL_EXEC.
+
+Next, the BFD library is called to open the object file,
+verify that it is an object file,
+and read its symbol table (@code{core.c:core_init}),
+using @code{bfd_canonicalize_symtab} after mallocing
+an appropiate sized array of asymbols. At this point,
+function mappings are read (if the @samp{--file-ordering} option
+has been specified), and the core text space is read into
+memory (if the @samp{-c} option was given).
+
+@code{gprof}'s own symbol table, an array of Sym structures,
+is now built.
+This is done in one of two ways, by one of two routines, depending
+on whether line-by-line profiling (@samp{-l} option) has been
+enabled.
+For normal profiling, the BFD canonical symbol table is scanned.
+For line-by-line profiling, every
+text space address is examined, and a new symbol table entry
+gets created every time the line number changes.
+In either case, two passes are made through the symbol
+table - one to count the size of the symbol table required,
+and the other to actually read the symbols. In between the
+two passes, a single array of type @code{Sym} is created of
+the appropiate length.
+Finally, @code{symtab.c:symtab_finalize}
+is called to sort the symbol table and remove duplicate entries
+(entries with the same memory address).
+
+The symbol table must be a contiguous array for two reasons.
+First, the @code{qsort} library function (which sorts an array)
+will be used to sort the symbol table.
+Also, the symbol lookup routine (@code{symtab.c:sym_lookup}),
+which finds symbols
+based on memory address, uses a binary search algorithm
+which requires the symbol table to be a sorted array.
+Function symbols are indicated with an @code{is_func} flag.
+Line number symbols have no special flags set.
+Additionally, a symbol can have an @code{is_static} flag
+to indicate that it is a local symbol.
+
+With the symbol table read, the symspecs can now be translated
+into Syms (@code{sym_ids.c:sym_id_parse}). Remember that a single
+symspec can match multiple symbols.
+An array of symbol tables
+(@code{syms}) is created, each entry of which is a symbol table
+of Syms to be included or excluded from a particular listing.
+The master symbol table and the symspecs are examined by nested
+loops, and every symbol that matches a symspec is inserted
+into the appropriate syms table. This is done twice, once to
+count the size of each required symbol table, and again to build
+the tables, which have been malloced between passes.
+From now on, to determine whether a symbol is on an include
+or exclude symspec list, @code{gprof} simply uses its
+standard symbol lookup routine on the appropriate table
+in the @code{syms} array.
+
+Now the profile data file(s) themselves are read
+(@code{gmon_io.c:gmon_out_read}),
+first by checking for a new-style @samp{gmon.out} header,
+then assuming this is an old-style BSD @samp{gmon.out}
+if the magic number test failed.
+
+New-style histogram records are read by @code{hist.c:hist_read_rec}.
+For the first histogram record, allocate a memory array to hold
+all the bins, and read them in.
+When multiple profile data files (or files with multiple histogram
+records) are read, the starting address, ending address, number
+of bins and sampling rate must match between the various histograms,
+or a fatal error will result.
+If everything matches, just sum the additional histograms into
+the existing in-memory array.
+
+As each call graph record is read (@code{call_graph.c:cg_read_rec}),
+the parent and child addresses
+are matched to symbol table entries, and a call graph arc is
+created by @code{cg_arcs.c:arc_add}, unless the arc fails a symspec
+check against INCL_ARCS/EXCL_ARCS. As each arc is added,
+a linked list is maintained of the parent's child arcs, and of the child's
+parent arcs.
+Both the child's call count and the arc's call count are
+incremented by the record's call count.
+
+Basic-block records are read (@code{basic_blocks.c:bb_read_rec}),
+but only if line-by-line profiling has been selected.
+Each basic-block address is matched to a corresponding line
+symbol in the symbol table, and an entry made in the symbol's
+bb_addr and bb_calls arrays. Again, if multiple basic-block
+records are present for the same address, the call counts
+are cumulative.
+
+A gmon.sum file is dumped, if requested (@code{gmon_io.c:gmon_out_write}).
+
+If histograms were present in the data files, assign them to symbols
+(@code{hist.c:hist_assign_samples}) by iterating over all the sample
+bins and assigning them to symbols. Since the symbol table
+is sorted in order of ascending memory addresses, we can
+simple follow along in the symbol table as we make our pass
+over the sample bins.
+This step includes a symspec check against INCL_FLAT/EXCL_FLAT.
+Depending on the histogram
+scale factor, a sample bin may span multiple symbols,
+in which case a fraction of the sample count is allocated
+to each symbol, proportional to the degree of overlap.
+This effect is rare for normal profiling, but overlaps
+are more common during line-by-line profiling, and can
+cause each of two adjacent lines to be credited with half
+a hit, for example.
+
+If call graph data is present, @code{cg_arcs.c:cg_assemble} is called.
+First, if @samp{-c} was specified, a machine-dependant
+routine (@code{find_call}) scans through each symbol's machine code,
+looking for subroutine call instructions, and adding them
+to the call graph with a zero call count.
+A topological sort is performed by depth-first numbering
+all the symbols (@code{cg_dfn.c:cg_dfn}), so that
+children are always numbered less than their parents,
+then making a array of pointers into the symbol table and sorting it into
+numerical order, which is reverse topological
+order (children appear before parents).
+Cycles are also detected at this point, all members
+of which are assigned the same topological number.
+Two passes are now made through this sorted array of symbol pointers.
+The first pass, from end to beginning (parents to children),
+computes the fraction of child time to propogate to each parent
+and a print flag.
+The print flag reflects symspec handling of INCL_GRAPH/EXCL_GRAPH,
+with a parent's include or exclude (print or no print) property
+being propagated to its children, unless they themselves explicitly appear
+in INCL_GRAPH or EXCL_GRAPH.
+A second pass, from beginning to end (children to parents) actually
+propogates the timings along the call graph, subject
+to a check against INCL_TIME/EXCL_TIME.
+With the print flag, fractions, and timings now stored in the symbol
+structures, the topological sort array is now discarded, and a
+new array of pointers is assembled, this time sorted by propagated time.
+
+Finally, print the various outputs the user requested, which is now fairly
+straightforward. The call graph (@code{cg_print.c:cg_print}) and
+flat profile (@code{hist.c:hist_print}) are regurgitations of values
+already computed. The annotated source listing
+(@code{basic_blocks.c:print_annotated_source}) uses basic-block
+information, if present, to label each line of code with call counts,
+otherwise only the function call counts are presented.
+
+The function ordering code is marginally well documented
+in the source code itself (@code{cg_print.c}). Basically,
+the functions with the most use and the most parents are
+placed first, followed by other functions with the most use,
+followed by lower use functions, followed by unused functions
+at the end.
