--- Comment #3 from Alexander Monakov <amonakov at gcc dot gnu.org> ---
I'm not sure Richard is correct about the definition of volatile asms: similar
to reads of volatile objects, volatile asms can produce different output on
each invocation (iow they are not pure/const).
In any case the inline asm in io() is missing clobbers for rcx, r11 and memory,
which makes the bug invalid.
