Hi.
With the patch one can see more info during debugging:
(gdb) pp
<edge (5 -> 6)>
5 [11.0% (guessed)] count:105119324 (estimated locally) (FALLTHRU,CAN_FALLTHRU,LOOP_EXIT)
Ready for trunk?
Thanks,
Martin
gcc/ChangeLog:
2019-05-31 Martin Liska <mliska@suse.cz>
* cfg.c (debug): Use TDF_DETAILS for debug and
print edge info only once.
