C compilers

Official compiler

SunPlus released sources for the C compiler. It doesn't include the assembler and is based on GCC 2.95 so quite hard to compile: https://github.com/vsmile-dev/unsp-gcc

VBCC

Work in progress port of vbcc: http://pulkomandy.tk/gerrit/plugins/gitiles/vbcc/+/refs/heads/unsp

The lack of vasm or another assembler with object file format and linker makes this hard to use. For now, the compiler generates output compatible with naken_asm, then all the output asm files need to be concatenated and fed directly into the assembler. And there isn't really support for sections or any fancy stuff like that, so getting the variables in RAM and the code in ROM is a bit messy.

Also, the code generation is completely unoptimized currently. Adding support for at least pre and post incrementation decrementation would be a great help in generating simpler code.

Assemblers

XASM is the original assembler provided by the µ'nSP IDE

naken_asm has support for µ'nSP and provides a standard include file for SPG200 registers.

Work in progress patch to add µ'nSP support in vasm. There are problems in vasm handling the pure 16-bit CPU, I have asked the vasm developers for help solving that.

This early homebrew experiment took an interesting approach of not using an assembler at all.
