To whom it may concern.
Hi, I’m James.
I would like to ask you a question about the ISA Extension of RISC-V.
I am currently working on adding MAC (Multiply-ACcumulate) instruction to the LLVM backend compiler.
As far as I know, the sequence of steps that I should follow is adding an intrinsic to recognize the IR pattern for MAC instruction and instruction addition for generating MAC instructions as assembly code.
Further jobs are required for gcc-assembler but this is not the concern right now.
Any clue or hint would sincerely be appreciated.
Thanks in advance.
