I don't remember anything relevant. It was probably over concerns about causing useless copies. I'd have to analyse the gcc source as it was in late 2004 to say anything definite. You should probably consider whether a copy to increase alignment is better in cases when the address of the parm does not escape. -- Alan Modra
