...ns) gather and scatter operations? If so, can you share with me the TableGen spec? (I tried to start from LD_DESC_BASE, but it doesn't seem to be trivial. Also, LLVM seems to have implemented scatter/gather instructions only for the x86 processor - there, they defined new SDNodes called GatherNode and ScatterNode.) Thank you, Alex

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. Working backwards from here, the actual PatFrags passed into this are things like ‘mgatherv4i32’. These are patterns that match a MaskedGatherSDNode for a particular data type....

i want to implement gather for v64i32. i wrote following code. def GATHER_256B : I<0x68, MRMSrcMem, (outs VR_2048:$dst), (ins i2048mem:$src), "GATHER_256B\t{$src, $dst|$dst, $src}", [(set VR_2048:$dst, (v64i32 (masked_gather addr:$src)))], IIC_MOV_MEM>, TA; def: Pat<(v64f32 (masked_gather addr:$src)), (GATHER_256B
