[Bug tree-optimization/15484] [tree-ssa] bool and short function arguments promoted to int


------- Additional Comments From nathan at gcc dot gnu dot org  2004-11-17 13:33 -------
The underlying ABI might require short & bool arguments to be passed as int. 
Some do, some don't.  Anyway, that's an argument marshalling issue, which is not
currently addressed at the tree level.

The cast to int has been inserted by the front end, I think C requires that.

This is a VRP issue, not an argument marshalling one.
