Or alternatively put the asm (""); right after asm goto,
asm volatile goto ("bts $1, %0; jc %l[lab]" : : "m" (b) : "memory" : lab);
asm ("");
return ...;
lab;
return ...;
What generates better code remains to be tested. In any case, please
conditionalize the hacks on non-fixed compilers once the fix is released.
