Side note: we'd hopefully/presumably never need anything _that_
disgusting for the kernel, so hjl's example is probably an extreme
one.
But even when we just did the pushq/popq_cfi macros etc to try to have
simple and reasonably legible annotations for the common cases, it got
pretty ugly.
It wasn't that extreme glibc kind of "50 lines of ugly for two
instructions of code", but it was pretty bad. And as far as I know we
never even tried to annotate places where we did "pushf/pop %reg" in
inline asm (for saving/restoring flags)
