[llvm-commits] [patch] Expose RTLIB/float-softening to targets

[Tim Northover]

Hi Akira,

> Doesn't aarch64 use library functions for soft-float (llc -soft-float)?

It probably would, but we haven't defined a soft-float ABI for
AArch64: the FPU is no longer an optional component. So unless that
happens it would be a non-standard extension, which obviously wasn't a
priority.

Cheers.

Tim.
