Thanks, actually it does turn out to be this, but I was confused by the
documentation. If this returns true, I see s

For all 3 targets I believe this returns true (Both MIPS and LM32 use
hook_bool_const_tree_true), so I presume it m

Try TARGET_PROMOTE_PROTOTYPES.

Hi,
I've tried compiling the following program targeting both MIPS, LM32 and
ARM.
long a, b;
void func(short p)
{
b = (long)p;
}
int main()
{
if(a < 2)
func((short)a);
return 0;
}
For MIPS and LM32, truncation is performed in the calling function and sig
