Hi,
Here is the patch #6. 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.
> 8. Merge in the MIPS backend that supports fixed-point instructions.
> 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.

Chao-ying
