PROF(1) PROF(1) NAME prof - display profile data SYNOPSIS prof [ -a ] [ -l ] [ -n ] [ -z ] [ -s ] [ -v [ -_l_o_w [ -_h_i_g_h ] ] ] [ a.out [ mon.out ... ] ] DESCRIPTION _P_r_o_f interprets the file produced by the _m_o_n_i_t_o_r subroutine. Under default modes, the symbol table in the named object file _(_a_._o_u_t default) is read and correlated with the profile file _(_m_o_n_._o_u_t default). For each external symbol, the percentage of time spent exe‐ cuting 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 more than one profile file is specified, the output represents the sum of the profiles. In order for the number of calls to a routine to be tallied, the -p option of _c_c_, _f_7_7 or _p_c must have been given when the file containing the routine was compiled. This option also arranges for the profile file to be produced automatically. Options are: -a all symbols are reported rather than just external symbols. -l the output is sorted by symbol value. -n the output is sorted by number of calls -s a summary profile file is produced in _m_o_n_._s_u_m_. This is really only useful when more than one profile file is specified. -v all printing is suppressed and a graphic version of the profile is produced on the standard output for display by the _p_l_o_t(1) filters. When plotting, the numbers _l_o_w and _h_i_g_h_, by default 0 and 100, may be given to cause a selected percentage of the pro‐ file to be plotted with accordingly higher resolution. -z routines which have zero usage (as indicated by call counts and accumulated time) are nevertheless printed in the output. FILES mon.out for profile a.out for namelist mon.sum for summary profile SEE ALSO monitor(3), profil(2), cc(1), plot(1G) BUGS Beware of quantization errors. Is confused by _f_7_7 which puts the entry points at the bottom of subrou‐ tines and functions. 4th Berkeley Distribution April 29, 1985 PROF(1)
