[PATCH] D99675: RFC [llvm][clang] Create new intrinsic llvm.arith.fence to control FP optimization at expression level

[Melanie Blower via Phabricator via llvm-commits]

mibintc updated this revision to Diff 337879.
mibintc edited the summary of this revision.
mibintc added a comment.

This is a minor update from @pengfei which allows simple tests cases to run end-to-end with clang.
Also I changed the "summary" to reflect the review discussion around the FMA optimization, to choose "FMA is not allowed across a fence".
