Subject: intel/fs: use uint type for per_slot_offset at GS
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=6706b421f042c9cc0d8c7d20e974791674acab2b;p=mesa.git

intel/fs: use uint type for per_slot_offset at GS

This helps us to compact original instruction:

mul(8)  g3<1>D  g6<8,8,1>UD  0x00000006UD { align1 1Q };

So now we emit:

mul(8)  g3<1>UD g6<8,8,1>UD  0x00000006UD { align1 1Q compacted };
