[PATCH] D156344: Disable call to fma for soft-float

[ChenZheng via Phabricator via cfe-commits]

shchenz added a comment.

compiler-rt builtins library should not just undefining fma for PPC, right (see https://gcc.gnu.org/onlinedocs/gccint/Soft-float-library-routines.html)? If so, maybe we should at least first try not generating fma for soft-float at the first place where fmul + fadd is fused, like `tryEmitFMulAdd` in clang front end?
