	* config/mips/mips.h (FIRST_PSEUDO_REGISTER): Rename FAKE_CALL_REGNO
	to GOT_VERSION_REGNUM.
	(CALL_REALLY_USED_REGISTERS): Set the GOT_VERSION_REGNUM entry to 0.

	(mips16_build_call_stub): Likewise.  Return the call insn or null.
	(mips_expand_call): Update the call to mips16_build_call_stub
	accordingly and a remove redundant condition.  Assert that MIPS16

	the call insn.
	(mips_extra_live_on_entry): Include GOT_VERSION_REGNUM if
	TARGET_USE_GOT.
	(mips_hard_regno_mode_ok_p): Allow SImode for GOT_VERSION_REGNUM.
	(mips_avoid_hazard): Remove hazard_set handling.
	* config/mips/mips.md (UNSPEC_EH_RECEIVER): Rename to...

	(restore_gp): ...this and update the unspec identifier accordingly.
	(exception_receiver, nonlocal_got_receiver): New expanders.
	(load_call<mode>): Use GOT_VERSION_REGNUM.  Don't set
	FAKE_CALL_REGNO.  Remove hazard_set attribute.
	(set_got_version, update_got_version): New patterns.

	PR target/34981
	* gcc.target/mips/lazy-binding-1.c: New test.
	* gcc.target/mips/mips.exp (setup_mips_tests): Set
	mips_forced_no_abicalls and mips_forced_no_shared.
	(dg-mips-options): Avoid using -mabicalls with an implicit -mabi=eabi.
	Avoid using small data with -mabicalls.  Don't make -G0 force
	-mn-abicalls.  Skip -mabicalls and -mshared tests if the multilib
	forces the opposite option.
