Applied to mips-fixes.
This makes a part of the user ABI, so I would advise discussing this with
libc folks. Also you probably want to report microMIPS support too.
Hi Maciej,
How can hwcap advance libc? I know that Arm world is using it to probe
SIMD extensions in high-level programs like ffmpeg.
microMIPS binary can't be applied at runtime, so userspace programs
shouldn't aware that.
Should I Cc this discussion to libc-alpha or other lists?
