https://gcc.gnu.org/bugzilla/show_bug.cgi?id=68413 --- Comment #5 from alahay01 at gcc dot gnu.org --- Yes, your right, I meant to say vectorizable_reduction - it's a reduction of a condition.

https://gcc.gnu.org/bugzilla/show_bug.cgi?id=68413 --- Comment #4 from Ilya Enkovich --- BTW I had an impression it was vectorizable_reduction which failed to transform, not vectorizable_condition.

https://gcc.gnu.org/bugzilla/show_bug.cgi?id=68413 --- Comment #3 from Ilya Enkovich --- r230309 refers to a vectorization of a comparison of boolean values. It shouldn't affect condition vectorizaion. Thus most probably check and build stages of vectorizable_condition are still inconsistent.

https://gcc.gnu.org/bugzilla/show_bug.cgi?id=68413 --- Comment #7 from Ilya Enkovich --- Looking deeper the difference is caused by different result of is_nonwrapping_integer_induction called for reduction related phi statement. For the first call it is: i_12 = PHI For the

https://gcc.gnu.org/bugzilla/show_bug.cgi?id=68413 --- Comment #6 from Ilya Enkovich --- I checked what is happening and seems the reason is in different STMT_VINFO_VEC_REDUCTION_TYPE (stmt_info) on analysis and transform phases. During analysis it is INTEGER_INDUC_COND_REDUCTION, for
