This is what I'm building my compiler with now, to make that change: http://git.infradead.org/users/dwmw2/gcc-retpoline.git/shortlog/refs/heads/retpoline-regnames At this point I'm inclined to suggest we don't make the change. I'll finish and test it anyway. I *can* change my GENERATE_THUNK macro to take two arguments — the suffix of the thunk name, and the register name to use. That lets me ditch the clever but ugly loop trick. I *did* want to get this file back to using .irp in the end, by fixing up other kernel infrastructure to do things properly. But I can live without that too if I must.
