I agree. LLVM tries to mimic GCC's inline-asm but falls over because it does
not treat it as a black box as GCC does. This is why LLVM keeps on adding
these "features". There are other "features" which LLVM adds to inline-asm to
try to get better inline-asm but it falls over when porting good inline-asm
from GCC to LLVM.
