predicates.md (const_call_insn_operand): Allow direct calls to locally-defined functions if TARGET_ABSOLUTE_ABICALLS.
* 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.
* doc/invoke.texi (-mabicalls): Update documentation.
(-mshared): Document.
