--- Comment #22 from Rich Felker <bugdal at aerifal dot cx> --- And to be clear, pretty much all gcc versions from 3.4.6 to present, and all clang/LLVM versions since they fixed some critical bugs (like -ffreestanding not working, which was a show-stopper), are supported compilers for targets they support. We do not drop support for some existing supported compilers because the latest version made an incompatible change.
