Q: Sibling calls

[Peter Nenzén <qinxpen at ks dot ericsson dot se>]

Hi!

With the new patch for sibcalls on sparc this program with void
functions works fine: 

  +void one(int x);
  +void two(int x);
  +
  +int main(void)
  +{
  +    one(0);
  +}
  +
  +void one(int x)
  +{
  +    printf("one %i\n",x);
  +    two(x+1);
  +} 
  +
  +void two(int x)
  +{
  +    printf("two %i\n",x);
  +    one(x+1);
  +}


But why doesn't this one work? It causes a segmentation fault.

  +int main(void) 
  +{
  +    one(0);
  +}
  +
  +int one(int x)
  +{
  +    printf("one %i\n",x);
  +    two(x+1);
  +}
  +
  +int two(int x)
  +{
  +    printf("two %i\n",x);
  +    one(x+1);
  +}
