--- Comment #3 from Richard Biener <rguenth at gcc dot gnu.org> ---
I'd say the patch can make a difference for when
if (!TEST_BIT (preferred, nalt)
|| TEST_HARD_REG_BIT (alts, nalt))
continue;
hit before. But I can't see any preferred_for_* pattern in i386 that also has
a '%' constraint ...
So it must be (somehow) to the "already processed" TEST_HARD_REG_BIT test, but
I can't imagine how.
