This is due to GIMPLE. The gimplifier restructures the trees in ways
that trigger false warnings like this one. This needs to be fixed but
for now you can just add a no-warning entry for regmove.c in
Makefile.in. There's a few of these already, they're clustered around a
FIXME note that describes this problem.
Thanks. Diego.
