@ -88,6 +88,32 @@ Removed support for legacy hexagonv2 and hexagonv3 processor architectures which
are no longer in use. Currently supported architectures arehexagonv4 and
hexagonv5.
Mips target
--------------
New features and improvements:
- Clang driver
- Support for Sourcery CodeBench Mips toolchain directories tree.
- Support for new command line options including:
- -mxgot/-mno-xgot
- -EL / -EB
- -mmicromips / -mno-micromips
- -msingle-float / -mdouble-float
- -mabi=32 (o32 abi) and -mabi=64 (n64 abi)
- Previously, options such as -mips16, -mmicromips, -mdsp and -mdspr2 were
not passed to the assembler. This issue has been fixed.
- A number of changes have been made to improve the quality of DSP-ASE code
generation.
- Multiply and multiply-accumulate instructions can now use all four
accumulators.
- Instruction selection patterns have been added so that DSP instructions
are emitted without having to use builtins.
- Delay slot filler pass can now search successor blocks for instructions to
fill delay slots (use option -disable-mips-df-succbb-search=false).
Loop Vectorizer
