Oh god vendor compilers.
The horror, the horror.
Seriously I don't understand it. Hardware companies make nice hardware then ship these amazingly shoddy compilers. Not only that they make them super-extra-mega-proprietary as if there is some great trade secret whereas they should be using such protction to hide their richly deserved shame.
Why do they get so uptight about the software which they are clearly so bad at?
Ah, when GCC started taking over from those it was sheer joy. And because of the GPL they seemed to realise that there wasn't much worth doing to it (though few of them seem to be able to resist fucking up GC a bit---almost all ICEs I've had have been with vendor-shittified GCC).
I hope the BSD license of LLVM doesn't give them funny ideas about how they can be all proprietary again. That would be a return to the bad old days.
