...of implementing in the LLVM Mips back end (part of the MSA vector instructions) gather and scatter operations? Simon Dardis would be able to confirm but there aren't any as far as I know. The closest I can think of is in MSA where you can get a similar effect with a sequence of ld.df's and vshf.df's (or pck*.df's, ilv*.df's, etc. for some of the common cases). > If so, can you share with me the TableGen spec?

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
