I am doing this for X86_64. You can look at the XRay lowering for the PATCHABLE_EVENT_CALL lowering in X86AsmPrinter as a guide for the lowering, but you might also want to see how we're inserting these pseudo-instructions from the I don't remember having to specify where the pass is defined, since it's already in the assembly printing. So you might consider inserting these...

Hello, I want to add assembly instructions at certain points in a function. This is X86 specific. So I am working in the lib/Target/X86 folder. I create a `MachineFunctionPass` in that folder. I register it in the X86TargetMachine.cpp in addPreEmitPass(). I use BuildMI to insert my own assembly instructions in the MachineFunctionPass. This works and my assembly instructions are inserted at
