I got mixed results with icc
for
--------------------------
short a;
void g(short);
void f(void)
{ g(a); }
----------------------
it produces a movswl. For
---------------------------
void g(int);
void f(short a) {
g(a);
}
--------------------------
it produces a movswq.
For the original test
-------------------------
void g(short);
void f(short a) {
g(a);
}
----------------------
it avoids the extension.
Cheers,
