	* config/mips/predicates.md (const_call_insn_operand): Allow direct
	calls to locally-defined functions if TARGET_ABSOLUTE_ABICALLS.
	* config/mips/mips.md (jal_macro): Test TARGET_ABSOLUTE_ABICALLS.
	Use TARGET_OLDABI instead of !TARGET_NEWABI.
	(loadgp): Use mips_current_loadgp_style.
	(loadgp_noshared): New pattern.
	(sibcall_internal): Use MIPS_CALL.
	(sibcall_value_internal): Likewise.
	(sibcall_value_multiple_internal): Likewise.
	(call_internal): Likewise.
	(call_value_internal): Likewise.
	(call_value_multiple_internal): Likewise.
	(call_split): Use MIPS_CALL and add an 'S' constraint.
	(call_value_split): Likewise.
	(call_value_multiple_split): Likewise.
	* config/mips/mips.opt (-mabicalls): Tweak docstring.
	(-mshared): New option.
	* config/mips/mips-protos.h (mips_loadgp_style): New enum.
	(mips_current_loadgp_style): Declare.
	* config/mips/mips.c (mips_classify_symbol): Avoid using
	SYMBOL_GOT_LOCAL if TARGET_ABSOLUTE_ABICALLS.  Use SYMBOL_GENERAL
	rather than SYMBOL_GOT_GLOBAL for locally-binding symbols if
	TARGET_ABSOLUTE_ABICALLS.
	(override_options): Adjust comments.  Improve the warning that is
	issued when -mabicalls and -G are used together.
	(mips_file_start): Remove comment.
	(mips_current_loadgp_style): New function.
	(mips_gnu_local_gp): New variable.
	(mips_emit_loadgp): Use mips_current_loadgp_style.  Handle
	LOADGP_ABSOLUTE.
	(mips_output_function_prologue): Use mips_current_laodgp_style.
	(mips_expand_prologue): Call mips_emit_loadgp before emitting
	the cprestore instruction.
	(mips_extra_live_on_entry): Fix reversed test.  Don't make $25
	live for TARGET_ABSOLUTE_ABICALLS.
	* config/mips/mips.h (TARGET_ABSOLUTE_ABICALLS): New macro.
	(ASM_SPEC): Pass down -mshared and -mno-shared.
	(MIPS_CALL): New macro.
	* config/mips/netbsd.h (TARGET_OS_CPP_BUILTINS): Remove __ABICALLS__
	definition.
