If you're interested, you should have a look at TCC (tiny CC) :
https://repo.or.cz/tinycc.git
It compiles extremely fast, implements some subsets of gcc (a few attributes for example), but is far from being able to compile a kernel (at least last time I checked). Its speed makes it very convenient for development. I made some efforts to make haproxy support it (and provided some fixes to tcc) as it compiles the whole project in 0.5 second instead of ~10 seconds with a modern gcc. It could probably compile a kernel in 15-20 seconds if properly supported, and this could be particularly handy for development and testing.
Regards, Willy
