You have the cproc compiler which does use the QBE backend. It generates much faster code than tcc since there are some basic optimization passes. On bz2 compression, with crude and basic testing, I got ~70% of the speed of gcc 13.1. tcc code is really slow, I am thinking of a QBE backend for tcc.
I would use that everywhere instead of the grotesquely and absurdely massive and complex gcc (and written in that horrible c++!). I would re-write in assembly some code hot spots. But it means those extra ~30% performance are accutely expensive, at least they could have been carefull to keep gcc written in simple and plain C99 (with benign bits of c11) to reduce the technical cost. Yeah, switching gcc to c++ is one of the biggest mistakes in open source software ever (hopefully, that mistake is not related to b. gates donations to MIT media labs revealed by the pedophile Epstein files... if all that is true though not to mention that would explain the steady ensh*tification of GNU software).
The problem is linux which does require bazillions of gcc extensions to even compile correct kernel code nowdays. You can see clang (which is no better, actually even worse) playing catchup with gcc for all the extensions creeps the kernel is getting.
All that stinks corpo-backed planned obsolescence, aka some kind of toxic worldwide scam.
