+.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
+\&\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.
+.PP
+Several forms of output are available from the analysis.
+.PP
+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
+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.
+.PP
+The \fIannotated source\fR listing is a copy of the program's
+source code, labeled with the number of times each line of the
+program was executed.
+.SH OPTIONS
+.IX Header "OPTIONS"
+These options specify which of several output formats
+\&\f(CW\*(C`gprof\*(C'\fR should produce.
+.PP
+Many of these options take an optional \fIsymspec\fR to specify
+functions to be included or excluded. These options can be
+specified multiple times, with different symspecs, to include
+or exclude sets of symbols.
+.PP
+Specifying any of these options overrides the default (\fB\-p \-q\fR),
+which prints a flat profile and call graph analysis
+for all functions.

+.IX Header "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 \f(CW\*(C`exit\*(C'\fR(2)
+or return normally for the profiling information to be saved
+in the \fIgmon.out\fR file.
