Hi Alex, I don’t know too much about recent MIPS, but have recently been doing something similar for the new ARM SVE architecture, so hopefully this will get you closer to what you need: If you’re looking where I think you are (lib/Target/X86/X86InstrAVX512.td), ‘GatherNode’ is a template argument, not a definition. It allows a PatFrag be passed into the avx512_gather multiclass definition.

Hello. I read on page 4 of http://www.cs.fsu.edu/~whalley/cda5155/chap4.pdf that gather and scatter operations exist for Mips, named LVI and SVI, respectively. Did anyone think of implementing in the LLVM Mips back end (part of the MSA vector instructions) gather and scatter operations? If so, can you share with me the TableGen spec? (I tried to start from LD_DESC_BASE, but it

This isn't a realistic/viable implementation, just a hacked up "can I make it produce the right output" kind of thing, but while I hammer out a few more details (like fixing MC to allow multiple sections with the same name but different comdat groups) I figured I'd throw it out there to have a bit of a chat about it. I've tested simple cases of a single type and they seem to
