Extend CONST_INT and symbolic handling to MIPS16, using
mips_symbol_insns to check that the base symbol type is a
legitimate constant. Reject GOT-based constants if
TARGET_MIPS16_PCREL_LOADS.
(mips_const_insns): Check targetm.cannot_force_const_mem when
decomposing a symbolic base and a large offset.
(mips_emit_call_insn): Add ORIG_ADDR and ADDR parameters.
When calling a function that needs $25 from MIPS16 code,
move the target address into $25 separately and add a USE
to the call insn.

before the first real insn.
(mips_pic_base_register, mips_got_load): New functions.

mips_expand_call. Set SYMBOL_REF_BIND_NOW on the symbol.
(mips16_build_call_stub): Replace the FN parameter with an
FN_PTR parameter. Force the address into a register if it
isn't a call_insn_operand; don't rely on the caller to do this.

function's local alias. Use mips16_stub_function_p,
mips16_stub_function, mips_expand_call and use_reg.

mips_call_type argument and handle the new MIPS_CALL_EPILOGUE value.

allowing it to modify the call address. Update the calls to
mips_load_call_address and mips_emit_call_insn.
(mips_split_call): New function.
(mips_init_relocs): Clear mips_split_hi_p. Only use %gp_rel if

and use mips_cprestore_slot.
(mips_output_function_prologue): Handle TARGET_MIPS16 for
LOADGP_OLDABI.
(mips_emit_loadgp): Move into MIPS16_PIC_TEMP for MIPS16,
then use a copygp_mips16 instruction to set up $28.
(mips_expand_prologue): Initialize the cprestore slot for MIPS16 too.
(mips16_lay_out_constants): Call split_all_insns_noflow.

false if TARGET_MIPS16.
(mips_reorg): Don't call vr4130_align_insns if TARGET_MIPS16.

mips_dangerous_for_la25_p approach for MIPS16 PIC calls too.

MIPS16 code. Allow MIPS16 o32 PIC.

* config/mips/mips.md: Lower CONST_GP_P moves into register moves
after reload if TARGET_USE_GOT.

(unspec_got<mode>, unspec_call<mode>): New expanders.
(load_got<mode>, load_call<mode>): Remove the length attributes.
Use a got attribute instead of a type attribute.
(copygp_mips16): New insn.
(restore_gp): Add a scratch clobber and pass it to mips_restore_gp.
(load_call<mode>): Use a "d" constraint instead of an "r" constraint.
(sibcall, sibcall_value, call, call_value): Update the calls
to mips_expand_call.
(call_internal, call_value_internal): Use mips_split_call.
(call_value_multiple_internal): Likewise.

define_insn_and_splits. Split if TARGET_SPLIT_CALLS.

mips_use_pic_fn_addr_reg_p check.
