While looking at Bug 13000 I noticed this bug.  Consider: 
 
static int foo (int a) { } 
int main (void) { return foo (0); } 
 
Compile this with "-O2 -Wall" and you can see that when finalizing 
`main' (after inlining foo of course), we produce this strange warning: 
 
t.i:2: warning: '({anonymous})' might be used uninitialized in this function 
 
Wtf  :-) 
 
Of course this is a regression from mainline and older GCCs. 
 
 
-------------- 
$ cat t.i 
static int foo (int a) { } 
int main (void) { return foo (0); } 
$ cc1 --version 
GNU C version 3.5-tree-ssa 20031119 (merged 20031111) (i686-pc-linux-gnu) 
        compiled by GNU C version 3.5-tree-ssa 20031119 (merged 20031111). 
GGC heuristics: --param ggc-min-expand=30 --param ggc-min-heapsize=4096 
$ cc1 -O -Wall t.i 
 foo

 main 
 
$ cc1 -O2 -Wall t.i

With little variations you can get all sorts of funny behavior:

==================================
int foo () {} 
int main () { return foo(); }
==================================
leads to

x.cc: In function `int foo()':
x.cc:1: warning: control reaches end of non-void function

which looks OK to me. However, with

==================================
int foo () {} 
int main () { return foo(); }
==================================

I get

x.cc: In function `int foo()':
x.cc:1: warning: no return statement in function returning non-void
x.cc: In function `int main()':
x.cc:2: warning: '<anonymous>' might be used uninitialized in this function

Volker: How do the two code snippets differ? I think one should be
different from the other, right?

Sorry. Cut-and-pasto. :-(
The second example should read

==================================
inline int foo () {} 
int main () { return foo(); }
==================================

Using my patch for 13863 (which I am about to post) and setting TREE_NO_WARNING 
for the decl which was created, this will be fixed.

Mine as I can fix this.

the fix would be set TREE_NO_WARNING in declare_return_variable on var, will test 
after the patch for 13863 is done testing.

The uninitialized warning is fixed, the only warning left is the one referenced in 13000, the testcase has 
been xfailed for it.
