mips.h (PROCESSOR_74KC, [...]): Define.
2007-04-16 David Ung <davidu@mips.com>
Joseph Myers <joseph@codesourcery.com>
* config/mips/mips.h (PROCESSOR_74KC, PROCESSOR_74KF,
PROCESSOR_74KX, TUNE_74K, GENERATE_MADD_MSUB): Define.
* config/mips/mips.c (mips_cpu_info_table, mips_rtx_cost_data):
Add 74K processor information.
* config/mips/mips.md: Include 74k.md.
(cpu): Add 74kc,74kf,74kx.
(ISA_HAS_MADD_MSUB): Change to GENERATE_MADD_MSUB throughout.
* config/mips/74k.md: New.
* doc/invoke.texi (MIPS Options): Document 74K support.
