GCC Turns 25

eldavojohn writes "With the release of GCC 4.7.0, the venerable and stalwart constant that is the GNU Compiler Collection turns twenty five. More ISO standards and architectures supported with this release and surely more memories to come from the compiler that seems to have always been."

They still do this with GCC. Because of the poor layering, getting a new target often requires hacking up various parts of the middle. Their goal is a working compiler, so they just do the minimum required to get their target working, at the expense of breaking others. These changes won't get incorporated into mainline GCC, so you're stuck with a GCC fork that's going to be unmaintained pretty soon.

In contrast, LLVM back ends are modular and quite easy to write and, more importantly, don't need to touch any of the rest of the system. This is why ARM is now investing quite a lot in LLVM and companies like Qualcomm have seemingly permanent job adverts for anyone with LLVM experience.
