Description Serge Belyshev 2004-10-30 22:42:03 UTC 
this is a fork from bug 16104

{
  return (long long) i;
}

Comment 1 Serge Belyshev 2004-10-30 22:45:31 UTC 
3.3.4 error: can't convert between vector values of different size
3.4.3 internal compiler error: in convert_move, at expr.c:588
4.4.0 error: invalid cast from type ‘int __vector__’ to type ‘long long int’
Comment 2 Andrew Pinski 2004-10-30 22:52:36 UTC 
For a slightly different test:
int foo  (int __attribute__ ((vector_size (8))) i)
{
  return (long long) i;
}
you only get an ICE if you add -mmmx.
Comment 3 Serge Belyshev 2004-10-30 23:04:18 UTC 
gcc and g++ 3.3.4: error: can't convert between vector values of different size
gcc and g++ 3.4.0: internal compiler error: in convert_move, at expr.c:588
g++ 4.0.0: invalid cast from type ‘int __vector__’ to type ‘long long int’

my gcc 4.0.0 accepted this even with -mmmx, hmm...
Comment 4 Andrew Pinski 2004-10-30 23:05:54 UTC 
Note I was using -O2.
