+ * config/mips/mips.c (machine_function): Remove
+ initialized_mips16_gp_pseudo_p.
+ (mips16_gp_pseudo_reg): Use cfun->machine->mips16_gp_pseudo_rtx to
+ detect whether a pseudo has already been created. Unconditionally
+ create a new one if not.
+ (mips_pic_base_register): Only call mips16_gp_pseudo_reg when
+ expanding to rtl. Create a new pseudo otherwise, if allowed.
