This program:
static
int x(int y)
__attribute__ ((regparm(1)));
static
int x(int y)
{
return y;
}
can't be compiled with GCC 3.4.4 20041224. The compiler complains:
y-bug.c:7: error: conflicting types for 'x'
y-bug.c:3: error: previous declaration of 'x' was here
y-bug.c:7: error: conflicting types for 'x'
y-bug.c:3: error: previous declaration of 'x' was here
It seems that it's a bug.

No this is not a bug. You need regparm attribute on the function
definition too.

Hmm... Is it regparm-only related? And is it something new though?
GCC 3.3.x doesnt show this behaviour.
