I clearly can't speak for GCC developers, but as an LLVM developer I have to say, this seems like a (somewhat rudely phrased) question for the LLVM mailing lists where there are people more familiar with the LLVM internals. Happy to reply in more depth there (or here if folks are actually interested).
