@whitequark oh I mean I hacked it in under a target triple check 




@stephentyrone @whitequark @FioraAeterna For stdlib implementors, supporting softfloat fenv is more work than errno.

@RichFelker@whitequark@FioraAeterna I agree, and both are abominations, which is why I want to tear the whole thing down. -
@stephentyrone@whitequark@FioraAeterna For fenv there's a standards-conforming way to say "don't need it":#pragma STDC FENV_ACCESS OFF -
@stephentyrone@whitequark@FioraAeterna Then, if the compiler can assume errno is not used, it can hoist ALL math functions at will.

@stephentyrone@whitequark@FioraAeterna My interest in dropping errno is to improve compilers. -
@stephentyrone@whitequark@FioraAeterna Most apps never care about math errno or fenv, but unless told not, compilers must assume they do. -
@RichFelker@whitequark@FioraAeterna Right. Which is why I want to tear the whole thing down. Errno is worse, but both are terrible.
