--- Comment #11 from Alexander Monakov <amonakov at gcc dot gnu.org> ---
No, you're mistaken. The clobber is outside of the live range of 'a'. There's
no clobber where 'a' is live:
register int a asm("eax");
a = 1;
asm("add %1, %0" : "+r"(o) : "r"(a));
Such situation could appear as a result of inlining, for example.
Do you realize that LLVM is implementing sane semantics promised by GCC's own
documentation without inventing new syntax for inline asm operands?
