[PATCH v3 0/2] MR587: vkd3d-shader/dxil: Implement DX intrinsic Tertiary.

[Conor McCarthy (＠cmccarthy)]

I'll revise the operand codes once !572 is upstream.

[PATCH v3 1/2] vkd3d-shader/dxil: Implement DX intrinsic Tertiary.

[Conor McCarthy]

From: Conor McCarthy

IBFE and UBFE are not emitted for HLSL sources which perform bitfield
extractions, e.g. loading a value from a struct containing bitfields, or
the equivalent done with bit shifts. These instructions are probably
only emitted by the TPF -> DXIL converter, which makes them hard to test.
