Bug ID: 91750 Summary: Induction vectorization introduces signed overflows Product: gcc Version: 10.0 Status: UNCONFIRMED Severity: normal Priority: P3 Component: tree-optimization Assignee: unassigned at gcc dot gnu.org Reporter: rguenth at gcc dot gnu.org Target Milestone: --- Split out from PR91665. int val[1024]; void foo (int n) { int i; for (int j = 0, i = n; j < 1024; ++j, i=(unsigned)i+1) val[j] = i; } generates signed add for the induction vectorization.
