Bug ID: 105083
Summary: scev_initialize should check for loop prerequesites
Product: gcc
Version: 12.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: middle-end
Assignee: unassigned at gcc dot gnu.org
Reporter: rguenth at gcc dot gnu.org
Target Milestone: ---
The SCEV code has prerequesites like looking at preheader edges or requiring
recorded exists but it does not verify presence of those in scev_initialize ().
It could also provide safe operation without those.
