When I try to compile some of our code for AVX512 with 'disable-zmm' parameter, I get following error:
"LLVM ERROR: Don't know how to split the result of this operator !"
Compiling without this parameter works fine. I was just curious if this option has (positive) impact on performance of generated code.
Repro case attached.

The minimized reproducer is:
void foo(uniform float output[], float a, float b) { float m = max(a, b); output[programIndex] = m; }
Compile with: ispc --target=avx512skx-x16 --opt=disable-zmm test.ispc --emit-obj -o test.o
ispc --target=avx512skx-x16 --opt=disable-zmm test.ispc --emit-obj -o test.o
Sorry, something went wrong.
