I did work a bit with cparser/libfirm and found the following:

* It took about 2 times longer to compile than gcc
* There was no x64 support yet
* It is not developed very actively, although the developers are responsive
* Some Programms had to be patched to be „libfirm-friendly“ and compilable
* Sometimes a lot of (in my understanding of the respective source) wrong
warnings popped up

In conclusion I would say it is not yet stable enough for production use, but
worth a look into, if you're interested in compilers.
