--- Comment #20 from Alexandre Oliva <aoliva at gcc dot gnu.org> --- The bug is now either fixed or latent in the trunk, I'm not sure which, because I have not got as far as figuring out why removing unnecessary address cselib lookups in debug insns made a difference to memory overlap checks between nondebug insns. So I'm not sure whether to close this PR or leave it open. Thoughts?
