Well done, Mr. Someone! Our toolchain has indeed been a big source of headaches for all involved.
A couple things:
1) Why stick to the 4.x.x series? More generally, is it worth the potential trouble to bump the major version? I'd be interested to measure performance gains with a more recent compiler (maybe in the less prominent codecs which haven't been completely hand-rolled in asm).
2) Testing. This change has the potential to introduce all sorts of insidious bugs. I'm usually of the "break-then-fix" mentality, but I feel like we should get some degree of testing done across targets/configurations before you merge this.
It looks to me like you've eliminated all the gory patches we used to rely on, too. Great work!
