As per previous comments, I looks at build_one_cst and implemented
build_minus_one_cst:
tree
build_minus_one_cst (tree type)
{
switch (TREE_CODE (type))
{
case INTEGER_TYPE: case ENUMERAL_TYPE: case BOOLEAN_TYPE:
case POINTER_TYPE: case REFERENCE_TYPE:
case OFFSET_TYPE:
return build_int_cst (type, -1);
case REAL_TYPE:
return build_real (type, dconstm1);
case VECTOR_TYPE:
{
tree scalar = build_minus_one_cst (TREE_TYPE (type));
return build_vector_from_val (type, scalar);
}
case COMPLEX_TYPE:
return build_complex (type,
build_minus_one_cst (TREE_TYPE (type)),
build_zero_cst (TREE_TYPE (type)));
case FIXED_POINT_TYPE:
default:
gcc_unreachable ();
}
}
However, I am unsure on how to best model the FIXED_POINT_TYPE case, if at all
possible.
