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 :-(

Description:

Closes: 94974 97904 100722 102353 105741 107633 108036 111613 116128 119635 121636 121668 123687 125649 127802 127890 128026 131399 134315 135967 137017 137959 140606 140995 141899 141900 141902 143912 144232 144584 146634 150232 155900 156792 158371 164135 165180 167569 167673 172353 173290
Changes:
gcc-3.0 (1:3.0.4ds3-14) unstable; urgency=low
.
* Build libstdc++ runtime only (on HPPA build gcc-3.0 as well as the
default compiler).
Note: The libstdc++ runtime does not build on a glibc-2.3.1 based
system!
* Add SH support.
* Backport patch from HEAD to build with bison > 1.35.
* Install gcj-wrapper (closes: #143912, #156792, #173290). Well this
doesn't help much as we don't build gcj-3.0 anymore ...
* Install fixed gij-wrapper (closes: #167569). Doesn't help anymore.
* Closing reports for the packages that are not built anymore from
this source package and are fixed in a newer version (gcc-3.2.x),
which becomes the default version now:
- General:
+ Use mkstemp instead of mktemp (closes: #127802).
- Preprocessor:
+ Fix redundant error message from cpp (closes: #100722).
- C:
+ Optimization issue on ix86 (pointless moving) (closes: #97904).

+ ICE on ia64 in instantiate_virtual_regs_1 (closes: #121668).
+ ICE in c-typeck.c (closes: #123687).
+ ICE in gen_subprogram_die on alpha (closes: #127890).
+ SEGV in initialization of flexible char array member (closes: #131399).
+ ICE on arm compiling lapack (closes: #135967).
+ ICE in incomplete_type_error (closes: #140606).
+ Fix -Wswitch (also part of -Wall) (closes: #140995).
+ Wrong code in mke2fs on hppa (closes: #150232).
+ sin(a) * sin(b) gives wrong result (closes: #164135).
- C++:
+ Error in std library headers on arm (closes: #107633).
+ ICE nr. 19970302 (closes: #119635).
+ std::wcout does not perform encoding conversions (closes: #128026).
+ SEGV, when compiling iostream.h with -fPIC (closes: #134315).
+ Fixed segmentation fault in included code for <rope> (closes: #137017).
+ Fix with exception handling and -O (closes: #144232).
+ Fix octave-2.1 build failure on ia64 (closes: #144584).
+ nonstandard overloads in num_get facet (closes: #155900).
+ ICE in expand_end_loop with -O (closes: #158371).
- Fortran:
+ Fix blas build failure on arm (closes: #137959).
- Java:
+ Interface members are public by default (closes: #94974).

+ Fix ObjectInputStream.readObject() calling constructors.
(closes: #121636).
+ gij: better error reporting on `class not found' (closes: #125649).
+ Lockup during .java->.class compilation (closes: #141899).
+ Compile breaks using temporary inner class instance (closes: #141900).
+ Default constructor for inner class causes broken bytecode.
(closes: #141902).
+ gij-3.2 linked against libgcc1 (closes: #165180).
+ gij-wrapper understands -classpath parameter (closes: #146634).
+ gij-3.2 doesn't ignore -jar when run as "java" (closes: #167673).
- ObjC;
+ ICE on alpha (closes: #172353).
