(although not the most elegant fix)
This fixes the rest of the problem, as there's no reaon to default promote
smaller than int sized
integers to int, they will end up being promoted if required by the back-end if
the target requires
them to be (also should not need to litterally promote enum's and bool beyond
the smallest int
type with suffecient to represent it's value range):
(called via default_conversion() to determine if an expression should be
converted by default to int)
*** In File: c-common.c ***
bool
c_promoting_integer_type_p (tree t)
{
switch (TREE_CODE (t))
{
- case INTEGER_TYPE:
- return (TYPE_MAIN_VARIANT (t) == char_type_node
- || TYPE_MAIN_VARIANT (t) == signed_char_type_node
- || TYPE_MAIN_VARIANT (t) == unsigned_char_type_node
- || TYPE_MAIN_VARIANT (t) == short_integer_type_node
- || TYPE_MAIN_VARIANT (t) == short_unsigned_type_node
- || TYPE_PRECISION (t) < TYPE_PRECISION (integer_type_node)); pws--*/
-
case ENUMERAL_TYPE:
/* ??? Technically all enumerations not larger than an int
promote to an int. But this is used along code paths
that only want to notice a size change. */
return TYPE_PRECISION (t) < TYPE_PRECISION (integer_type_node);
case BOOLEAN_TYPE:
return 1;
default:
return 0;
}
}
