--- Comment #1 from Alexander Monakov <amonakov at gcc dot gnu.org> ---
Yes, thanks for the report. OK with -fno-tree-dominator-opts.

The dom2/dom3 passes duplicate most of the computations in build_filter for=
 the
'x =3D=3D 0' branch, but the phi node in the resulting basic block 5 incorr=
ectly
receives 0.0 (from bb 6) as the value of 'ffm' computed on the duplicated p=
ath
(should be 1.0).=
