Jakub Jelinek <jakub at gcc dot gnu.org> changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |jakub at gcc dot gnu.org --- Comment #2 from Jakub Jelinek <jakub at gcc dot gnu.org> 2012-12-10 17:44:57 UTC --- Can't be reproduced starting with http://gcc.gnu.org/viewcvs?root=gcc&view=rev&rev=193157 (made latent on this testcase), but if I revert the patch I can reproduce it easily. The bug is in lra-constraints.c, loc_equivalence_change_p really doesn't work well on DEBUG_INSNs.
