PROF(I) 3/12/73 PROF(I)
NAME
prof - display profile data
SYNOPSIS
prof [ -v ] [ -a ] [ -l ] [ file ]
DESCRIPTION
Prof interprets the file mon.out produced by the monitor
subroutine. Under default modes, the symbol table in the
named object file (a.out default) is read and correlated
with the mon.out profile file. For each external symbol,
the percentage of time spent executing between that symbol
and the next is printed (in decreasing order), together with
the number of times that routine was called and the number
of milliseconds per call.
If the -a option is used, all symbols are reported rather
than just external symbols. If the -l option is used, the
output is listed by symbol value rather than decreasing
percentage. If the -v option is used, all printing is
suppressed and a profile plot is produced on the 611
display.
In order for the number of calls to a routine to be tallied,
the -p option of cc must have been given when the file
containing the routine was compiled.
