Paul Schlie said: "The further good news is that upon reviewing the DWARF2 spec in detail, and GCC's implementation, it's clear that a 32-bit DWARF data structure is sufficient to support any target with 32-bit or less data type sizes. "(which seems that it may be reasonably easy to support by declaring the DWARF data structure size as a function of the size of target's the maxim declared data type size; although possibly limited to a practical minimum of 32-bits, which seems much more reasonable for smaller targets)" but no-one has ever AFAIAA submitted a patch that does this.
