Using the .l syntax is not right here. This is not a true16 operand, cos you can't specify v0.h but you can specify v255.l (with an 8-bit instruction field). So it's a normal 32-bit operand but the instruction happens to only use the low 16 bits of data from it.

Yes I think Jay is right, though the docs here are somewhat misleading. The operand is labeled as a vgpr with 16 bits. However, there is no way to encode the swizzle (ie v0.h) in DS. At least I can't find any reference that these would use the hi bit of the operand field the way vop1/2/C does.
