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 --------------- -- cgit v1.2.3
