mips.c (machine_function): Remove initialized_mips16_gp_pseudo_p.
gcc/
* 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.
