--- Comment #3 from Jakub Jelinek <jakub at gcc dot gnu.org> ---
The patch regresses the tree-ssa/ssa-ifcombine-10.c testcase, but that to me
just looks as tree-ssa-ifcombine.c being not enough flexible. The difference
starting with VRP1 without -> with the patch is just:
@@ -27,14 +27,14 @@ f (int x, int a, int b)
<bb 3>:
_5 = x_3(D) & 4;
if (_5 != 0)
- goto <bb 4>;
- else
goto <bb 5>;
+ else
+ goto <bb 4>;
<bb 4>:
<bb 5>:
- # t_1 = PHI <0(2), 3(4), 0(3)>
+ # t_1 = PHI <0(2), 3(3), 0(4)>
return t_1;
which I'd say is quite unimportant difference ifcombine shouldn't care about,
but apparently it does.
