Hi experties ..!

I am trying to understand custom instruction added using a python script for orca(RISCV(32IM)) .I want to add intrinsic instruction in my c code using gcc for these instructions

for example

{"vadd.sehhhsss", "Xlve", "d,s,t", MATCH_VADD_SEHHHSSS, MASK_VADD_SEHHHSSS, match_opcode, 0 }

This is generated using attached file(opcode-lve.py)

Can you please refer any tutorial for adding intrinsic in my code . Give me any hint ...
