Would it be better to just ensure that the buffer for DW_OP_piece is at least the size of the type instead? To do this right we would really need to track which bytes in the buffer are actually valid. This patch assumes we will always get the first N bytes of a value. Is it possible to describe bytes 4:7 of a 16 bit value where bits 0:3 and 8:15 are not valid? In this case, with this patch, we would think that bytes 0:3 are valid when they are just not specified, 4:7 would be valid, and 8:15 would not display because our value doesn't contain the value.
