Summary: -Wunused-but-set-variable does not report unread
unit-static variables
Product: gcc
Version: 4.6.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c
AssignedTo: [email protected]
ReportedBy: [email protected]
I know this is likely cumbersome to support as a case, as it requires to look
at all the functions in the given unit to report it, but since GCC already
reports unused functions in the unit I guess it is feasible.
Simple test case:
static unsigned int done = 0;
int main() {
done = 1;
return 0;
}
The warning works fine if done is function-static though.
Thanks,
Diego
