+.SH "DESCRIPTION"
+.IX Header "DESCRIPTION"
+\&\f(CW\*(C`gprof\*(C'\fR 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
+(\fIgmon.out\fR default) which is created by programs
+that are compiled with the \fB\-pg\fR option of
+\&\f(CW\*(C`cc\*(C'\fR, \f(CW\*(C`pc\*(C'\fR, and \f(CW\*(C`f77\*(C'\fR.
+The \fB\-pg\fR option also links in versions of the library routines
+that are compiled for profiling.  \f(CW\*(C`Gprof\*(C'\fR reads the given object 
+file (the default is \f(CW\*(C`a.out\*(C'\fR) and establishes the relation between
+its symbol table and the call graph profile from \fIgmon.out\fR.
+If more than one profile file is specified, the \f(CW\*(C`gprof\*(C'\fR
 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.
+\&\f(CW\*(C`Gprof\*(C'\fR 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.
+Several forms of output are available from the analysis.
 .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.
+The \fIflat profile\fR 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.
 .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.
+The \fIcall graph\fR 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.

+@c man begin DESCRIPTION
+@code{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
+(@file{gmon.out} default) which is created by programs
+that are compiled with the @samp{-pg} option of
+@code{cc}, @code{pc}, and @code{f77}.
+The @samp{-pg} option also links in versions of the library routines
+that are compiled for profiling.  @code{Gprof} reads the given object 
+file (the default is @code{a.out}) and establishes the relation between
+its symbol table and the call graph profile from @file{gmon.out}.
+If more than one profile file is specified, the @code{gprof}
+output shows the sum of the profile information in the given profile files.
+
+@code{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.
+
+@c man end
+
+@c man begin 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.
+
+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.
+
+The profiled program must call @code{exit}(2)
+or return normally for the profiling information to be saved
+in the @file{gmon.out} file.
