This is a live mirror of the Perl 5 development currently hosted at
First steps of making builds outside the source
[perl5.git] / ext / Devel / DProf / Todo
1- work on test suite.
2- localize the depth to guard against non-local exits.
3Current overhead (with PERLDBf_NONAME) wrt non-debugging run (estimates):
4 8% extra call frame on DB::sub
5 7% output of subroutine data
6 70% output of timing data (on OS/2, 35% with custom dprof_times())
7(Additional 17% are spent to write the output, but they are counted
8 and subtracted.)
10With compensation for DProf overhead all but some odd 12% are subtracted ?!
12- Calculate overhead/count for XS calls and Perl calls separately.
13- goto &XSUB in pp_ctl.c;
