I am working on supporting x64 right now (with atrac3+ support on windows) and improving the compiler performance. Also I have improved the memcpy, memset emulator is using internally making it much faster (almost 10x). Also I have been working on improving lwl/lwr instructions that allow to read unaligned words.
Results are awesome. And make lot of compilerPerf tests 10x faster than a real PSP.
You can see the results here (running in 64-bits and with the new lwl/lwr improvement):64-bits fixed the LWC1 performance problem on Intel platforms.
Still lots of things to improve:
- Local variable usage
- Improve function calling
