i965/vec4: Fix exec size for MOVs {SET,PICK}_{HIGH,LOW}_32BIT.
Otherwise for a pack_double_2x32_split opcode, we emit:
vec1 64 ssa_135 = pack_double_2x32_split ssa_133, ssa_134
mov(8) g5<1>UD g5<4>.xUD { align16 1Q compacted };
mov(8) g7<2>UD g5<4,4,1>UD { align1 1Q };
ERROR: When the destination spans two registers, the source must span two registers
(exceptions for scalar source and packed-word to packed-dword expansion)
mov(8) g8<2>UD g5.4<4,4,1>UD { align1 2N };
ERROR: The offset from the two source registers must be the same
mov(8) g5<1>UD g6<4>.xUD { align16 1Q compacted };
mov(8) g7.1<2>UD g5<4,4,1>UD { align1 1Q };
ERROR: When the destination spans two registers, the source must span two registers
(exceptions for scalar source and packed-word to packed-dword expansion)
mov(8) g8.1<2>UD g5.4<4,4,1>UD { align1 2N };
ERROR: The offset from the two source registers must be the same
The intention was to emit mov(4)s for the instructions that have ERROR
annotations.
See tests/spec/arb_gpu_shader_fp64/execution/vs-isinf-dvec.shader_test
for example.
v2 (Samuel):
- Instead of setting the exec size to a fixed value, don't double it
(Curro).
- Add PICK_{HIGH,LOW}_32BIT to the condition.
