Package: gcc-3.0
Version: 1:3.0.4-6
Severity: normal
-Wswitch doesn't actually seem to do anything in gcc-3.0, although it
works in gcc 2.95.4. Here's what the documentation says it *should*
do:
------------------------------------------------------------------------
`-Wswitch'
Warn whenever a `switch' statement has an index of enumeral type
and lacks a `case' for one or more of the named codes of that
enumeration. (The presence of a `default' label prevents this
warning.) `case' labels outside the enumeration range also
provoke warnings when this option is used.
------------------------------------------------------------------------
Here's a sample program:
------------------------------------------------------------------------
enum foo {
FUBAR = 0,
SNAFU = 1
};
int main(void)
{
enum foo boop;
switch (boop) {
case FUBAR:
break;
case 3:
break;
}
return 0;
}
------------------------------------------------------------------------
and here's what happen with gcc 2.95.4:
------------------------------------------------------------------------
volition:~/tmp$ gcc -Wswitch switch.c
switch.c: In function `main':
switch.c:16: warning: enumeration value `SNAFU' not handled in switch
switch.c:16: warning: case value `3' not in enumerated type `foo'
volition:~/tmp$ gcc --version
2.95.4
volition:~/tmp$
------------------------------------------------------------------------
but here's what happens with gcc-3.0:
------------------------------------------------------------------------
volition:~/tmp$ gcc-3.0 -Wswitch switch.c
volition:~/tmp$
------------------------------------------------------------------------
I normally compile with gcc 3.0 since it has so many more warnings
that I can turn on, so this is somewhat disheartening :-(
