--- Comment #8 from Georg-Johann Lay <gjl at gcc dot gnu.org> --- ...more questions: TARGET_IRA_CHANGE_PSEUDO_ALLOCNO_CLASS: Same issue: This hook can change a reload class. The purpose is clear for regalloc guys, but when and d why and how would I do it for a specific backend? The hook has two "reg_class_t" parameters as inputs, and no parameter does even have a name. "default hook always returns given class" ... Which one? There are two indestinguishible ones.
