Hi,
this patch ensures that types defined with __attribute((mode(xI))) which
are smaller than an int get promoted to int if necessary even if there is
no corresponding native C type. It checks for each xImode type
individually; I'm not sure if just checking whether an INTEGER_TYPE is
smaller than an int is sufficient here. Should that be the case I'll
simplify and resubmit the patch.
Bootstrapped and regtested on sparc-sun-solaris2.8.
Bye
Roman
