Thank you. i understood how avx512 vector instructions are written in x86instravx512. i need to define my vector instructions so i wrote;
def VMOV_256B_RM : I<0x6F, MRMSrcMem, (outs VR2048:$dst), (ins i32mem:$src),
“vmov_256B_rm\t{$src, $dst|$dst, $src}”,
[(set VR2048:$dst, (v64i32 (scalar_to_vector (loadi32 addr:$src))))],
IIC_MOV_MEM>, EVEX;
def VMOV_256B_MR : I<0x7F, MRMDestMem, (outs), (ins i32mem:$dst, VR2048:$src),
“vmov_256B_mr\t{$src, $dst|$dst, $src}”,
[(store (i32 (bitconvert VR2048:$src)), addr:$dst)], IIC_MOV_MEM>, EVEX;
in x86instrinfo.td;
when i build i got these instructions in X86GenInstrInfo.
but still my instruction is not selected when i run input file in debug mode; getting following errors;
===== Instruction selection begins: BB#1 ‘vector.body’

What could be the reason of this?? Please correct me.
I am stuck at this point…
