[LLVMdev] How to use INC64m instruction in X86-64?

Hi all,

Sorry to interrupt those not interested. I inserted an INC64m instruction
in the program after register
allocation in the backend. However, the program will get aborted or run in
dead loop.

I wonder whether this instruction will change register file so that my
program get aborted?

By the way, I wonder whether there are any methods that I can instrument
the program after register
allocation so that I can count the number of certain instruction
