Subject: [PATCH] math: move x86_64 fabs, fabsf to C with inline asm
---
Questions:
Why are there amd64-specific fabs implementations in the first place?
(Only) because GCC generated poor code for the generic C version?
Do annotations for mask manipulation in the patch help? Any way to make
them less ambiguous?
