Hi.
The patch is about dbgcnt support for match in GIMPLE and GENERIC.
It's handy for isolation of a problem.
Ready to be installed after it survives tests?
Thanks,
Martin
gcc/ChangeLog:
2019-07-03 Martin Liska <mli...@suse.cz>
* dbgcnt.def (DEBUG_COUNTER): Add gimple_match and
generic_match.
* genmatch.c (dt_simplify::gen_1): Generate dbgcnt
condition.
* generic-match-head.c: Include dbgcnt.h.
* gimple-match-head.c: Likewise.
