The documentation for this comes under the Passing Function Arguments on
the Stack section, which says:
This target hook returns true if an argument declared in a prototype as an
integral type smaller than int should actually be passed as an int. In
addition to avoiding errors in certain
Hi Eric,
I guess my question is what would I need to change to make it work
like the ARM port? I can't see how this is being controlled.
Try TARGET_PROMOTE_PROTOTYPES.
Thanks, actually it does turn out to be this, but I was confused by the
documentation. If this returns true, I see sign

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

Hi Eric,

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