Many ports have them various forms of secondary reloads and scratch registers for reload.I need a hard register for a define_insn output. I have had issues before when using clobber in a define_insn pattern; I will give it another try. Is there an example I can be pointed to where a temporary hard register is obtained via secondary reload ?
Search for "secondary_reload", "reload_in", "reload_out" in the various target directories for many examples.
