Hi Nick
Thank you for your reply.
Your example is OK.
But I'm not clear.
> extension being performed. Eg:
> int bar (int a) { return a < func(); }
If the func() is external function, output code is the following.
_bar:
push.l r7
mov.L r1, r7
bsr _func
mouv.B r1, r1
cmp r7, r1
scgt.L r1
rtsd #4, r7-r7
If the return value is zero exteneded,
"movu.B r1, r1" code can be removed.
Is the explanation san integer conversion rank?

I think that my request is depend on rx cpu target like sh, m32r not m32c.
