* config/mips/mips.h (GLOBAL_POINTER_REGNUM): New macro.
(PIC_OFFSET_TABLE_REGNUM): Look at pic_offset_table_rtx after reload.
(STARTING_FRAME_OFFSET): Don't allocate a cprestore slot for
n32/64 PIC.
(MUST_SAVE_REGISTERS): Delete.
* config/mips/mips.c (mips_frame_info): Remove extra_size field.
(machine_function): Add global_pointer field.
(mips_classify_constant): Check for (const $gp) using pointer equality
with pic_offset_table_rtx.
(mips_classify_constant): Handle RELOC_LOADGP_HI and RELOC_LOADGP_LO.
(mips_restore_gp): Use current_function_outgoing_args_size.
(print_operand): Use PIC_OFFSET_TABLE_REGNUM instead of
GP_REG_FIRST + 28. Handle relocation strings that have
more than one '('.
(mips_reloc_string): Handle RELOC_LOADGP_HI and RELOC_LOADGP_LO.
(mips_global_pointer): New function.
(mips_save_reg_p): New function, mostly split out from...
(compute_frame_size): ...here. Remove handling of extra_size.
Reclaim args_size if no variables depend on it. Don't treat gp
as a special case: handle it in the main GPR loop.
(mips_initial_elimination_offset): Fix comment.
(save_restore_insns): Save every register in the GPR mask,
removing distinction between mask and real_mask.
(mips_output_function_prologue): Update .frame psuedo-op after
the removal of extra_size. Move the SVR4 PIC stack allocation
and cprestore instructions to mips_expand_prologue.
(mips_gp_insn): New function.
(mips_expand_prologue): Set REGNO (pic_offset_table_rtx) to
the chosen global pointer. Handle SVR4 PIC stack allocation
in the same way as other ABIs. Adjust varargs code accordingly.
Emit a cprestore insn after allocating the stack. Use mips_gp_insn
to emit the loadgp sequence. Follow it with a loadgp_blockage
if not using explicit relocs.
(mips_output_function_epilogue): Reinstate the default gp register.
(mips16_gp_pseudo_reg): Use pic_offset_table_rtx.
(mips16_optimize_gp): Likewise.
* config/mips/mips.md (UNSPEC_LOADGP): Remove.
(UNSPEC_SETJMP, UNSPEC_LONGJMP): Remove.
(UNSPEC_CPRESTORE, RELOC_LOADGP_HI, RELOC_LOADGP_LO): New.
(loadgp): Remove.
(loadgp_blockage, cprestore): New instructions.
(builtin_setjmp_setup): Implement using emit_move_insn. Use
pic_offset_table_rtx.
(builtin_setjmp_setup_32, builtin_setjmp_setup_64): Remove.
(builtin_longjmp): Use gen_raw_REG to force use of $28.
