[PATCH] D81869: Modify FPFeatures to use delta not absolute settings to solve PCH compatibility problems

[Melanie Blower via Phabricator via cfe-commits]

mibintc updated this revision to Diff 273133.
mibintc added a comment.

I decided that I shouldn't make float options that define a macro, like -ffast-math, as BENIGN_LANGOPT, I made ffp-contract= , fp-exception-behavior and rounding-mode BENIGN, I modified the pch test case to test that the benign command line floating options on the pch-create don't affect compilations that use the pch file.

@rjmccall thought this patch looked OK.  I'll commit tomorrow unless I receive more change requests.  Thanks a lot!

BTW I'll be away from my desk on Intel Sabbatical starting June 27 and returning Aug 31. I expect I'll be checking in here and there but I won't be able to tackle any major problems.
