--- Comment #7 from Frank Ch. Eigler <fche at redhat dot com> ---
The systemtap operand encoding machinery separately gives us the byte-size of
the operand, so even if gcc told us %si, we'd only look at %sil only anyway.
But if gcc cannot let that level of ambiguity be, then I guess we must work
around the change.
In the sdt.h, we enjoyed using machine-independent operant-constraint codes -
until now, I guess.
