I wonder if this inline-asm with the register is valid or not.

--- Comment #2 from Jiu Fu Guo <guojiufu at gcc dot gnu.org> ---
This may be the same issue as PR111971.

It is ok if it is "register long d asm ("r0") = 0x24;".

The 'd' is 'long long' DImode(64bits), but with -m32, "r0" is not 64bits
without -mpowerpc64.  This may be a reason for the issue.
