Bug ID: 63440 Summary: -Og does enable -fmerge-constants too Product: gcc Version: 4.9.1 Status: UNCONFIRMED Severity: normal Priority: P3 Component: other Assignee: unassigned at gcc dot gnu.org Reporter: rdiezmail-gcc at yahoo dot de The documentation for -fmerge-constants does not mention that the new optimization level -Og does enable -fmerge-constants too. Or at least it seems to do, judging by the generated code size in my tests.
