Hi,
Has anyone had a go at building musl with Tiny-CC http://bellard.org/tcc/?
I was trying to see what the smallest self-hosting Linux system I
could make was, but had grief building musl due to TCC's lack of
complex support (which is relatively easily removed from musl, just a
couple of #includes and removing the src/complex directory). I then
had problems with <stdarg.h> (va_list not being properly defined), and
finally a crash in tcc which I couldn't quite track down. Before I get
into it too much more, I was wondering if anyone had done this before?
Regards,
Andre

If I remember correctly, last I checked, libfirm/cparser was working
fine for static linking, but did not support dynamic linking (it
completely lacked position-independent code generation, i.e. -fPIC).
There were some problems with complex and some floating point things,
but I think they were all fixed. I built a static libc.a with cparser
and the results passed basic testing.
This is definitely the most promising GCC-alternative compiler I've
seen, so if anybody's up for helping promote it and/or contribute to
the project, that would be great.

I contributed a bit and I'm routinely filling bugs to it.
It is indeed easy to work with and the upstream developers are pleasant
to work with.
They indeed need more mindshare. I hope once they converted cparser to
an usable library they'll bloom fully.

Could you elaborate on the stdarg.h problem? It might just work to use
the legacy non-GNUC definitions. I can't recall whether anyone has
successfully built musl with tcc. My guess would be that the dynamic
linking doesn't work, but static linking might.

i tried tcc long ago, but not the mob-branch
it didnt support c99 vlas (musl has some can be fixed)
it failed to compile some of the asm (you can change $(CC) to gnu as)
however it had issues with inline asm as well
