- create a clang built-in in Builtins.td
- link dot4add_i8packed in hlsl_intrinsics.h
- add lowering to spirv backend through expansion of operation as OPSDot
is missing up to SPIRV 1.6 in SPIRVInstructionSelector.cpp
- add lowering to spirv backend using OpSDot in applicable SPIRV version
or if SPV_KHR_integer_dot_product is enabled
- add dot4add_i8packed intrinsic to IntrinsicsDirectX.td and mapping to
DXIL.td op Dot4AddI8Packed
- add tests for HLSL intrinsic lowering to dx/spv intrinsic in
dot4add_i8packed.hlsl
- add tests for sema checks in dot4add_i8packed-errors.hlsl
- add test of spir-v lowering in SPIRV/dot4add_i8packed.ll
- add test to dxil lowering in DirectX/dot4add_i8packed.ll
