--- Comment #5 from avieira at gcc dot gnu.org --- Im slightly confused here, on entry to BB 5 we know the opposite of _1 < 0.0 no? if we branch to BB 5 we know !(_1 < 0.0) so we can't fold _1 <= 1.0, we just know that the range of _1 is >= 0.0 . Or am I misreading, I've not tried compiling myself just going off the code both of you posted here.
