[PATCH] D39304: [IR] redefine 'reassoc' fast-math-flag and add 'trans' fast-math-flag

[Quentin Colombet via Phabricator via llvm-commits]

qcolombet added a comment.

BTW, while writing the RFC, I realized that we could potentially generated incorrect code if we were silently downgrade a post-r317488 bitcode with a pre-r317488 compiler. (I.e., running fast math optimizations whereas we only wanted reassoc)
