I am debugging an embedded RISC CPU at my company, and I need to be able to compile C-like code to this CPU's assembler, and assemble that to object code. I will only be dealing with very simple programs, so I don't expect to need a linker. I have taken a look at the GCC and GAS code, and find it quite opaque (I'm more an electrical engineer than a programmer). If I thought I could do the job with a few weeks of hacking, I'd dive in, but I can't really estimate how long it will take. What would be the most straightforward way for me to implement this compiler/assembler? How long would it take a very experienced programmer to modify GCC/GAS to some arbitrary, simple, new instruction set? How long for a modestly experienced (>40k lines of C, >10k lines of elisp) programmer? David Wuertele dave@aoa.com
