Hello!

Attached RFC patch enhances stringop patterns to emit addr32 prefix
when Pmode == SImode. I have introduced %^ operand modifier that
conditionally emits "addr32" to all stringop insn templates.

H.J., can you please test the patch if it works OK on SImode X32
target? I have tested it on x86_64-pc-linux-gnu {,-m32}, but I can't
test anything else than that it doesn't break compilation and
regression tests.

Thanks,
Uros.
