If you're interested, you should have a look at TCC (tiny CC) :

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.
