NAME
prof - display profile data
SYNOPSIS
prof [ option ] ... [ a.out [ mon.out ... ] ]
DESCRIPTION
Prof interprets files produced by monitor(3) or the -p option of cc,
f77, or pascal(1). The symbol table in the named object file (`a.out'
by default) is read and correlated with the profile file (`mon.out' by
default). For each external symbol, the percentage of time spent exe‐
cuting between that symbol and the next is printed (in decreasing or‐
der), together with the number of times that routine was called and the
number of milliseconds per call. If more than one profile file is
specified, the output represents the sum of the profiles.
Call counts are tallied for subroutines compiled under option -p, which
also causes a profile file to be produced automatically.
Options are:
-a report all symbols, not just external symbols.
-l sort the output by symbol value
-n
sort the output by number of calls
-s produce a summary profile file in mon.sum
-v -low -high
produce a graphic profile on the standard output for display by
the plot(1) filters; optional numbers low and high, by default 0
and 100, select a percentage of the profile to be plotted
-z include routines with zero usage in the output
FILES
mon.out for profile
a.out for namelist
mon.sum for summary profile

BUGS
Beware of quantization errors.
Prof is confused by f77 which puts the entry points at the bottom of
subroutines and functions.
