/* ADJUST_REG_ALLOC_ORDER is a macro which permits reg_alloc_order to be rearranged based on a particular function. On the mips16, we want to allocate $24 (T_REG) before other registers for instructions for which it is possible. */ #define ADJUST_REG_ALLOC_ORDER mips_order_regs_for_local_alloc () I'm just wondering if it Is appropriate to simply remove ADJUST_REG_ALLOC_ORDER considering its comment.
