Unfortunately this is still a slow-down, since you also add object flags to the value. I would still prefer a variant to the ECMA_GET_NON_NULL_POINTER macro.
ECMA_INTERNAL_VALUE_GET_POINTER / ECMA_INTERNAL_VALUE_SET_POINTER

I would prefer
#define ECMA_SET_INTERNAL_VALUE_POINTER(field, non_compressed_pointer) \
ECMA_SET_NON_NULL_POINTER((field), (non_compressed_pointer))

I'd use similar style for the macro like below.
#define ECMA_SET_INTERNAL_VALUE_POINTER(field, non_compressed_pointer) \
field = (ecma_value_t) non_compressed_pointer

…value directly. This changes affects those internal properties where the property value type is an ecma_object_t ptr. JerryScript-DCO-1.0-Signed-off-by: Robert Sipka rsipka.uszeged@partner.samsung.com
