--- Comment #10 from Martin Jambor <jamborm at gcc dot gnu.org> --- (In reply to H.J. Lu from comment #9) > The same bug affects 252.eon in SPEC CPU 2000 on x32: ... > > The fix isn't sufficient since adding -fno-ipa-cp fixes eon on x32. I really doubt that it is "the same bug." Just that -fno-ipa-cp avoids it certainly does not suffice to make that conclusion. Anyway, I will try to find some time to look soon, although setting up x32 environment will take me some time. I suppose this bug also manifests itself with -O3 and LTO?
