--- Comment #21 from Uroš Bizjak <ubizjak at gmail dot com> --- (In reply to Alexander Monakov from comment #19) > I get the feeling that you're ignoring me, but gcc-4.8.3 was already > emitting a helper fmod call for setting errno without any flag_errno_math > checks in i386.md, i.e. it was already in the middle-end. As was mentioned > in comment #9. When g:93ba85fdd253b4b9cf2b9e54e8e5969b1a3db098 is reverted, current mainline does not emit anything that would handle errno (even with -fmath-errno flag explicitly set at command line).
