InvalidFunctionCall: Unexpected llvm intrinsic: 7> llvm.vector.reduce.or.v4i8

Hi,

I've been getting this error when translating some kernels:

InvalidFunctionCall: Unexpected llvm intrinsic:
7> llvm.vector.reduce.or.v4i8

Is this a supported function?

Hi, unfortunately there is no SPIR-V counterpart for this intrinsic to translate it appropriately. But still you can pass '--spirv-allow-unknown-intrinsics' option to the translator, in this case it will emit a regular function call in SPIR-V. In general it's not a good idea to add this option by default, since there is no guarantee the the device's SPIR-V consumer would support such intrinsic, but may it it would help in your case.

Resolved by emulation of the intrinsic in #2198
