I can't help but thinking the code is valid and that this is a valid bug.
Arguably, it *might* be hard to fix, and we'll have to cop out and adjust the
documentation instead.
I mean, the "i" constraint purpose is documented as:
"this includes symbolic constants whose values will be known only at assembly
time or later."  In this case, "later" is link-time.  In some cases, including
variables, the "later" would be dynamic-link-time which will be a bit beyond
reach; but as long as GCC generates an internal label, it should work with no
warnings.  See also PR19708 and 17346.  If the C standard defines something
other than programmer sense for "symbolic constant", that isn't as interesting;
we're already in asm-land and are supposed to be useful, not pedantic.  Taking
the address of a constant string is useful...

And oh, I almost forgot to mention that I get the warning with 3.2 for
cris-axis-linux-gnu too.  Yes, in the kernel, for the same use. (Sigh.)
I'm a bit behind on gcc work so I don't know if I get it for 4.2 as well.
I assigned the PR to me to avoid the feeling of adding to peoples workload,
but I guess I'll have to hack trees and that might take a while.
