Generating a custom opcode from an LLVM intrinsic
Here's a couple examples for mapping an intrinsic to an X86 instruction from X86InstrInfo.td. If you look for int_x86_* in any X86Instr*.td you can find others. let Predicates = [HasCLFLUSHOPT], SchedRW = [WriteLoad] in def CLFLUSHOPT : I<0xAE, MRM7m, (outs), (ins i8mem:$src), "clflushopt\t$src", [(int_x86_clflushopt addr:$src)], IIC_SSE_PREFETCH>, PD; let Predicates = [HasCLWB], SchedRW = [WriteLoad] in def CLWB : I<0xAE, M...

Generating a custom opcode from an LLVM intrinsic
Hello all. LLVM newbie here. If anything seems glaringly wrong with my use of LLVM, that's probably why. Here's what I'm trying to do. I have modified the gem5 simulator to accept a "new" x86 instruction. I've done this by just reserving the opcode in gem5's ISA specification, just as all other instructions are specified. I'm trying to get an LLVM backend to
