@zwarich @pervognsen nop-ing is fine compared to relaxation. AArch64 doesn't have variable-width instructions, and doesn't delete instructions during relaxation (shuffling everything afterwards)

@zwarich @pervognsen risc-v will do things like rewrite registers in instructions, delete instructions, rewrite them with a smaller variant, etc etc etc. Now remember that alignment needs to be preserved and enjoy your headache.
