Description
Linking a compute shader with the command-line DXC will error out if using -Fd and -Qstrip_debug together. This is not consistent with the compiler, which will output a PDB even if debug info is stripped from the object file.

Steps to Reproduce
Create a file named test.hlsl:

RWTexture2D<uint> rwTexResource[] : register(u0, space2400);
[numthreads(8, 8, 1)]
void main(uint3 dtid : SV_DispatchThreadID, uint3 gtid : SV_GroupThreadID, uint3 gid : SV_GroupID, uint gindex : SV_GroupIndex)
{
    rwTexResource[0][dtid.xy] = texResource.Load(dtid.xyz);
}

Run these commands:

dxc.exe -T lib_6_3 -Zi -Qstrip_reflect -Qembed_debug -Fd testc.pdb -Fo test.lib test.hlsl
dxc.exe -link -T lib_6_3 -Zi -Qstrip_reflect -Qstrip_debug -Fd test.pdb -Fo test.bin test.lib

Actual Behavior
DXC fails with error:
dxc failed : DXIL container does not contain the given part.

Environment

  • DXC version dxcompiler.dll: 1.7 - 1.7.2207.3 (e9137cd); dxil.dll: 1.7(101.7.2207.10)
  • Host Operating System Windows 10
