Hi Matthew,

Please find attached updated patch as per our offline discussion.

I have disabled return in registers for all vector float types, and updated the test case accordingly.

Ok for trunk?

- Thanks and regards,
  Sameera D.

Subject: [PATCH, MIPS] Calling convention differs depending on the presence of MSA

Hi Matthew,

Please find attached the patch to fix the calling convention issue,
where argument and result passing convention differed for MSA and
non-MSA variants.

The implementation of TARGET_RETURN_IN_MEMORY is altered to block V4SF to be returned in registers.

Ok for trunk?

- Thanks and regards,
  Sameera D.


Changelog:
gcc/
    * config/mips/mips.c (mips_return_in_memory) : Restrict V4SFmode to be returned in registers.

gcc/testsuite/
    * gcc.target/mips/msa-fp-cc.c : New testcase.
