[Bug c++/44062] New: (void)var; doesn't prevent 'set but not used' warning

2010-05-10 Thread jeffrey dot donner at gmail dot com 
Doing

  (void)var;

does not 'use' the var, eg: 

  void f()
  {
 int i = 6; // or a fn call whose return value you don't care about
 (void)i;
  }

j...@shade:~$ g++ -Wall -Wextra unused.cpp
unused.cpp: In function ‘void f()’:
unused.cpp:3:8: warning: variable ‘i’ set but not used
[-Wunused-but-set-variable]

Doing this (void)var; trick is a long-standing way to quiet 'unused' warnings -
eg in g++ 4.4.3 there is no warning. 

Version used:

j...@shade:~$ g++ --version
g++ (GCC) 4.6.0 20100508 (experimental)

[Bug c++/44106] New: False warning: 'control reaches end of non-void function' when comparing to undefined var

2010-05-12 Thread jeffrey dot donner at gmail dot com 
int f(int i)
{
   if (i == undefined_var) {
  return 1;
   }
   else {
  return 0;
   }
}

/usr/local/gcc-svn/bin/g++ -Wall -Wextra -c bad-return.cpp
bad-return.cpp: In function ‘int f(int)’:
bad-return.cpp:3:13: error: ‘undefined_var’ was not declared in this scope
bad-return.cpp:9:1: warning: control reaches end of non-void function
[-Wreturn-type]

Happens as .c and gcc, and as .cpp with g++. The warning does not occur in
4.4.3. Untried with 4.5.x.

Occurs in GCC 4.5.1 also.
