trafficstars
Very bare bones, doesn't work yet. But it's a start.
Small programs can work, for example GOARCH=mipsle tinygo run -scheduler=none -gc=leaking ./testdata/alias.go
Size difference with the dev branch:
Binary size difference

This should be working for the most part, including syscalls, goroutines, defer/recover, the FPU, etc.
A few things are still missing:
- ~testdata/math.go crashes. I'm suspecting a LLVM bug but I need to investigate more deeply.~ fixed. Of course this wasn't an LLVM bug but rather a bug in TinyGo (see #4312).
- 64-bit atomics aren't supported yet. These don't seem to be supported by the hardware, I don't know how they're normally implemented?
Marked as draft until #4312 is merged and I have updated the CI files to rebuild LLVM (with Mips support).
Added support for big-endian mips (GOARCH=mips) too, though it currently has bugs.
Ready for review!
GOARCH=mipsleworks, and is tested in CI. The only thing that doesn't work is 64-bit atomics. (It looks like upstream uses a simple lock mechanism, so that's something we could copy).GOARCH=mipscompiles but has bugs. Small programs tend to work but a few features (like CGo, reflect and maps) have bugs. Probably because this is the first big-endian system that TinyGo tries to support.
