[PATCH] D65399: [InstCombine] canonicalize fneg before fmul/fdiv

[Michael Berg via Phabricator via llvm-commits]

mcberg2017 added a comment.

General comment: For us internally at Apple this does cause regressions, its small but there.   Mostly because fneg becomes a side effect for fp arithmetic ops for us.  I would request a target info guard which we can turn off to avoid the drift.  If not, this is small enough to live with,
