Bug ID: 84180
Summary: -Wimplicit-fallthrough=2 heuristic fails when
condition in the case
Product: gcc
Version: 7.3.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c
Assignee: unassigned at gcc dot gnu.org
Reporter: Patrick.Schluter at ec dot europa.eu
Target Milestone: ---
A case containing a condition recognizes that it may fall through but the
heuristic to suppress the warning doesn't work at level 2. IMO it should.
Simple example to trigger the behaviour
case OPEN_FILE:
if( !access(name, F_OK)) {
...
break;
}
/* fallthrough */
case CREATE_FILE:
...
The warning is suppressed only at level 1 of the -Wimplicit-fallthrough=
option.
