Bug ID: 85978 Summary: config/frv/frv.c: 3 * iffy code in switch Product: gcc Version: 8.0 Status: UNCONFIRMED Severity: normal Priority: P3 Component: target Assignee: unassigned at gcc dot gnu.org Reporter: dcb314 at hotmail dot com Target Milestone: --- Target: frv gcc/config/frv/frv.c:6715:7: warning: this statement may fall through [-Wimplicit-fallthrough=] gcc/config/frv/frv.c:6741:7: warning: this statement may fall through [-Wimplicit-fallthrough=] gcc/config/frv/frv.c:6766:7: warning: this statement may fall through [-Wimplicit-fallthrough=] Source code for the first one is switch (to) { default: break; Instead merely carrying on with the code after the switch, and going into the next case for the outer switch, perhaps better code would flag up in some way the unexpected value of "to" ?
