Bug ID: 114340 Summary: ` X / CST < X` -> `X > 0` Product: gcc Version: 14.0 Status: UNCONFIRMED Keywords: missed-optimization Severity: enhancement Priority: P3 Component: tree-optimization Assignee: unassigned at gcc dot gnu.org Reporter: pinskia at gcc dot gnu.org Target Milestone: --- int f(int x) { return x / 100 < x; } Can be transformed into just: int f(int x) { return x > 0; } For signed types. For unsigned types, it is `x != 0` (but that is also `x > 0` really).
