Subject: nvir: Always split 64-bit IMAD/IMUL operations
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=21b92b3464193a203e069f50c21ebec146ae0215;p=mesa.git

nvir: Always split 64-bit IMAD/IMUL operations

Those operations do not map to actual hardware instructions, therefore
those should always be lowered to 32-bit instructions.

Fixes: 009c54aa7af "nv50/ir: Split 64-bit integer MAD/MUL operations"
