configure.ac: Test assembler support for DSP Rev1 mult.
2010-11-04 Chao-ying Fu <fu@mips.com>
* configure.ac: Test assembler support for DSP Rev1 mult.
* configure: Regenerate.
* config.in: Regenerate.
* config/mips/mips.h (ISA_HAS_DSP_MULT): New define.
* config/mips/mips.c (CODE_FOR_mips_mult): New define.
(CODE_FOR_mips_multu): New define.
(mips_builtins): Move madd, maddu, msub, msubu, mult, multu from
dspr2_32 to dsp_32.
(mips_mulsidi3_gen_fn): Test (TARGET_FIX_R4000 && !ISA_HAS_DSP).
Delete returns when ISA_HAS_DSPR2, because the old patterns are deleted.
* config/mips/mips-dsp.md (mips_madd<u>, mips_msub<u>):
New define_expand patterns.
* config/mips/constraints.md (ka): Update the constraint to test
ISA_HAS_DSP_MULT instead of ISA_HAS_DSPR2.
* config/mips/mips-dspr2.md (mips_madd<u>, mips_msub<u>, mips_mult,
mips_multu): Delete.
* config/mips/mips.md (<u>mulsidi3_32bit): Add comments.
Change target constraint to "ka".
Use (!TARGET_FIX_R4000 || ISA_HAS_DSP), instead of
(!TARGET_FIX_R4000 && !ISA_HAS_DSPR2).
Emit the accumulator destination when ISA_HAS_DSP_MULT.
(<u>msubsidi4): Add comments.
Test ISA_HAS_DSP.
Emit the accumulator destination when ISA_HAS_DSP_MULT.
(<u>maddsidi4): Likewise.
* doc/extend.texi (MIPS DSP Built-in Functions): Move madd, maddu,
msub, msubu, mult, multu built-in functions from DSP r2 to DSP r1.
