MIPS: Fix asm constraints "f" and "r" for softfloat (#79116) 2024-02-27T06:08:36+00:00 YunQiang Su syq@debian.org 2024-02-27T06:08:36+00:00 c88beb4112d5bbf07d76a615ab7f13ba2ba023e6 This include 2 fixes: 1. Disallow 'f' for softfloat. 2. Allow 'r' for softfloat. Currently, 'f' is accpeted by clang, then LLVM meets an internal error. 'r' is rejected by LLVM by: couldn't allocate input reg for constraint 'r'. Fixes: #64241, #63632 --------- Co-authored-by: Fangrui Song <i@maskray.me> 
This include 2 fixes:
        1. Disallow 'f' for softfloat.
        2. Allow 'r' for softfloat.

Currently, 'f' is accpeted by clang, then LLVM meets an internal error.

'r' is rejected by LLVM by: couldn't allocate input reg for constraint
'r'.

Fixes: #64241, #63632
