This tells me that there is 1 result but and 2 operands. But then it says that operands 2 and 1 are of the same type, SDTCisSameAs<2, 1>. Given that operand numbering starts at 0, how...

Hello. Will, thanks a lot for pointing me to the MaskedGatherSDNode and mgatherv4i32. I have to say that the definition of the "multiclass avx512_gather" from lib/Target/X86/X86InstrAVX512.td is difficult to follow and I prefer not to use it. I currently have some serious problems with TableGen - it gives an assertion failure:

When LLVM does a comparison of two vectors, in this case with 16 elements, the returned type of setcc is v16i1. The architecture I'm targeting allows storing the result of a vector comparison as a bit mask in a scalar register, but I'm having trouble converting the result of setcc into a value that is usable there. For example, if I try to AND together masks that are the results of two
