Description

fatal error: generated SPIR-V is invalid: The Component Type of Vector 1 must be the same as ResultType.
  %23 = OpVectorShuffle %v4bool %22 %19 4 5 6 3

when compiling this code:

RWStructuredBuffer<bool4> Out : register(u1);

[numthreads(1,1,1)]
void main() {
  
  Out[1].xyz = or(true,false);
}

Note: it also fails for 'and'

Interface variables cannot be bool. We convert them to int. We have to add cast to and from bool in the correct spots, and we seem to be missing one here.
