[PATCH] D87528: Enable '#pragma STDC FENV_ACCESS' in frontend cf. D69272 - Work in Progress

[Melanie Blower via Phabricator via cfe-commits]

mibintc updated this revision to Diff 296520.
mibintc added a comment.

I added a sentence in the clang UserManual pointing out that ffp-model=strict automatically enables FENV_ACCESS. I changed checkFloatingPointResult the way @sepavloff suggested to solve the LIT failure in clang/test/AST/const-fpfeatures.cpp, as long as the ExceptionBehavior is Ignore, the FENV_ACCESS is Off and RoundingMode isn't Dynamic, it's OK to fold even if the Status isn't OK. Now check-clang is running clean.
