[libc-commits] [PATCH] D152923: [libc] Add support for FMA in the GPU utilities

[Tue Ly via Phabricator via libc-commits]

lntue added a comment.

I would assume that the fma instructions on GPU will be more performant than normal multiply + add.  Do you want to let generic math functions use fma's for GPUs?
