Hi, Here is the patch #8. Please review it. Thanks! > 1. Merge in machine modes to support signed and unsigned > fract and accum modes. Handle scalar and vector modes. DONE! > 2. Merge in fixed-value.h and fixed-value.c to handle fixed-point values. (fixed-value.diff) > 3. Merge in TREE structures for fixed-point types and constants. (tree.diff) > 4. Merge in C front-end changes to parse _Sat, _Fract and _Accum. (c-parser.diff) > 5. Merge in RTL structures for fixed-point constants and operators. (rtl.diff) > 6. Merge in libcpp to parse fixed-point constants. (cpp.diff) > 7. Merge in changes to support "case" of FIXED_POINT_TYPE, FIXED_CST, > and CONST_FIXED in .c and .h files. (changes.diff) > 8. Merge in the MIPS backend that supports fixed-point instructions. (mips.diff) > 9. Merge in configure/build system changes for the runtime library. > 10. Merge in testsuite (from gcc.dg/fixed-point) that only run > when the compiler is configured to enable fixed-point. Regards, Chao-ying gcc/ChangeLog 2007-08-01 Chao-ying Fu <fu@mips.com> * config/mips/mips.c (mips_scalar_mode_supported_p): Declare. (TARGET_SCALAR_MODE_SUPPORTED_P): Define. (mips_emit_compare): Process fixed-point modes. (mips_pad_arg_upward): Support fixed-point types. (override_options): Allow fixed-point modes in accumulators. (mips_pass_by_reference): Pass DQ, UDQ, DA, and UDA modes in registers. (mips_vector_mode_supported_p): Support V2HQmode, V2UHQmode, V2HAmode, V2UHAmode, V4QQmode, and V4UQQmode when TARGET_DSP. (mips_scalar_mode_supported_p): New function to accept fixed-point modes if the width is not greater than two BITS_PER_WORD. * config/mips/mips.h (SHORT_FRACT_TYPE_SIZE, FRACT_TYPE_SIZE, LONG_FRACT_TYPE_SIZE, LONG_LONG_FRACT_TYPE_SIZE, SHORT_ACCUM_TYPE_SIZE, ACCUM_TYPE_SIZE, LONG_ACCUM_TYPE_SIZE, LONG_LONG_ACCUM_TYPE_SIZE): Define. * config/mips/mips.md (mips-fixed.md): Include. * config/mips/mips-modes.def: Create VECTOR_MODES for FRACT, UFRACT, ACCUM, UACCUM. * config/mips/mips-fixed.md: New file.
