* doc/install.texi (--with-mips-plt): Document.
* doc/invoke.texi (-mplt, -mno-plt): Document.
* config.gcc (mips*-*-*): Add mips-plt to supported_defaults
and handle ${with_mips_plt}.
* config/mips/mips.opt (mplt): New option.
* config/mips/mips.h (TARGET_ABICALLS_PIC0): New macro.
(TARGET_ABICALLS_PIC2): Likewise.
(TARGET_GPWORD): Return false for TARGET_ABSOLUTE_ABICALLS.
(OPTION_DEFAULT_SPECS): Add a mips-plt entry.
(ASM_SPEC): Use !mabi=* instead of !mabi*.
(MIPS_CALL): Use TARGET_ABICALLS_PIC2 instead of TARGET_ABICALLS
to decide whether to output ".option picX" directives.
* config/mips/linux.h (SUBTARGET_ASM_SPEC): Remove -mabi=64 handling.
Pass -call_nonpic rather than -KPIC for -mplt.
(BASE_DRIVER_SELF_SPECS): Remove -mplt if -mno-shared is not present
on the command line. Also remove it when -mabi=64 is used without
-msym32.
* config/mips/linux64.h (SUBTARGET_ASM_SPEC): Delete.
* config/mips/mips.c (mips_use_pic_fn_addr_reg_p): Handle
TARGET_ABICALLS_PIC0.
(mips_classify_symbol): Use TARGET_ABICALLS_PIC2 instead of
TARGET_ABICALLS.
(mips16_build_function_stub): Only output ".option pic" directives
and PIC stubs if TARGET_ABICALLS_PIC2. Call through $25 instead of $1.
(mips16_build_call_stub): Fix comment and remove redundant
".set at"/"set .noat" directives.
(mips_function_rodata_section): Use the default behaviour for
TARGET_ABSOLUTE_ABICALLS.
(mips_file_start): Emit ".option pic0" for TARGET_ABICALLS_PIC0.
(mips_global_pointer): Handle TARGET_ABICALLS_PIC0.
(mips_restore_gp): Do nothing if the current function doesn't use
a global pointer.
(mips_expand_prologue): Only save $gp if the current function uses it.
Use a normal move for TARGET_ABICALLS_PIC0.
(mips_override_options): Only set flag_pic if TARGET_ABICALLS_PIC2.
