Add support for Loongson EXT instructions.
gcc/
* config/mips/mips.h (TARGET_CPU_CPP_BUILTINS): Add
__mips_loongson_ext.
(MIPS_ASE_LOONGSON_EXT_SPEC): New.
(BASE_DRIVER_SELF_SPECS): march=loongson3a implies
-mloongson-ext.
(ASM_SPEC): Add mloongson-ext and mno-loongson-ext.
* config/mips/mips.md (mul<mode>3, mul<mode>3_mul3_nohilo,
<u>div<mode>3, <u>mod<mode>3, prefetch): Use TARGET_LOONGSON_EXT
instead of TARGET_LOONGSON_3A.
* config/mips/mips.opt (-mloongson-ext): Add option.
* gcc/doc/invoke.texi (-mloongson-ext): Document.
gcc/testsuite/
* gcc.target/mips/mips.exp (mips_option_groups): Add
-mloongson-ext option.
(mips-dg-options): Add mips_option_dependency options
"-mmicromips" vs "-mno-loongson-ext",
