"--file-ordering" options.
(usage): Add new options to usage message.
(main): Handle new options.
* gprof.h (STYLE_FUNCTION_ORDER): Define.
(STYLE_FILE_ORDER): Define.
(function_mapping_file): Declare.
* cg_arcs.c (arcs, numarcs): New globals.
(arc_add): Put new arcs into the arc array so the function/file
ordering code can examine them.
* cg_arcs.h (struct arc): New field "has_been_placed".
(arcs, numarcs): Declare new globals.
* core.c (symbol_map, symbol_map_count): New globals.
(read_function_mappings): New function to read in a function
to object map file.
(core_init): Call read_function_mappings if a function mapping
file exists.
(core_create_function_syms): Handle function to object file
mappings.
* symtab.h (struct sym): New fields "mapped", "has_been_placed",
"nuses", "prev".
* cg_print.c (cmp_arc_count): New function for sorting arcs.
(cmp_fun_nuses): Likewise for functions.
(cg_print_function_ordering): New function to print a suggested
function ordering.
(cg_print_file_ordering): Likewise for ordering .o files.
(order_and_dump_functions_by_arcs): Helper function for function
and object file ordering code.
Gprof changes for mentor vm work.

set if ignore_non_function is set.
* gprof.h (ignore_non_functions): Declare.
* gprof.c (ignore_non_functions): Define.
(long_options): Add "ignore-non-functions".
(usage): Add new options.
(main): Recognize "-D" and "--ignore-non-functions" option.
So we can get more accurate information on Solaris, HPUX and other
systems that can uniquely identify function symbols.

Alpha support.
Long options.
New file format to support more information; backwards compatibility.
Line-level profiling, on systems where bfd_find_nearest_line works.
Selective display of data.

decls extern to keep native HP compiler quiet.

representations.
* gprof.c (getpfile, openpfile, readsamples): Swap data in using
new structures.

Ads LDFLAGS and use in place of CFLAGS where appropriate.
* configure.in: Make a sysdep.hlink in the same way other
bfd-based directories do.
* gprof.h (UNIT): Replace non-standard 'u_short' by 'unsigned
short'.
* gprof.h: #include sysdep.h instead of a bunch of stuff.
* gprof.c (main): Fix typo gproff->gprof.

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.

on both the sparc (SunOS) and Mach386 systems, more or less. (The differences
are at least partially due to what I think might be bugs in the native
gprof.)
