1038 if replace is true. Return a value.
1039 When changing address reload types for operands that didn't get
1040 reloaded, use RELOAD_FOR_OPADDR_ADDRESS for

1082 Handle inheritance from auto_inc expressions.
1083 (emit_reload_insns): If reload_in is a MEM, set OLD to
1085 Don't reload directly from oldequiv; if it's a pseudo with a

1088 from reg_reloaded_contents.
1089 Include non-spill registers in reload inheritance processing.

1124 Don't clear after_call for a CLOBBER.
1125 Keep track of how many hard registers need to be copied from
1126 after_call, and don't clear after_call before we have seen
