/* Initialize for caller-save.
Look at all the hard registers that are used by a call and for which
- regclass.c has not already excluded from being used across a call.
+ reginfo.c has not already excluded from being used across a call.
Ensure that we can find a mode to save the register and that there is a
simple insn to save and restore the register. This latter check avoids
SET_HARD_REG_BIT (hard_regs_used, r);
