Bug ID: 72739 Summary: [7 Regression] FAIL: gcc.dg/vect/vect-mask-store-move-1.c after r238301 Product: gcc Version: 7.0 Status: UNCONFIRMED Severity: normal Priority: P3 Component: tree-optimization Assignee: unassigned at gcc dot gnu.org Reporter: ysrumyan at gmail dot com Target Milestone: --- We noticed that after this revision test is failed: FAIL: gcc.dg/vect/vect-mask-store-move-1.c scan-tree-dump-times vect "Move stm t to created bb" 4 FAIL: gcc.dg/vect/vect-mask-store-move-1.c -flto -ffat-lto-objects scan-tree- dump-times vect "Move stmt to created bb" 4 The problem is caused by complete deletion of vectorized loop which requires run-time alias check. Note that GCC 6 does not have such issue.
