[Bug c/44478] -Wunused- but-set-variable is incredible noisy in kernel builds

[andi-gcc at firstfloor dot org]

------- Comment #5 from andi-gcc at firstfloor dot org  2010-06-09 11:08 -------
Hmm yes there was another temporary and a inline inbetween

unsigned inlinefunc(void)
{
   unsigned var;
   asm(" ... " : "=r" (var));
   return var;
}

#define macro(x,y)
{ 
unsigned var = inlinefunc();
x = var;
y = var >> 16;
};

caller macro(x,y)      y is just a dummy
