Bug Description
Are we using 64-bit DWARF or not? That's a DWARF3 item, not called out
explicity whether we use or not; DWARF 2 does not mention 64-bit DWARF. Based on
our definition of the length fields, it looks like we do.
THe problem is, if we use 64-bit DWARF there are places where some fields we
call out explicitly as 4-byte are actually either 4-byte or 8-byte, depending on
whether 32-bit or 64-bit DWARF is in use. This is not actually arch-specific I
don't believe; consumers of these data can tell by looking at the length field:
"If Length contains the value 0xffffffff, then the length is contained the
Extended Length field." which also looks to be the indicator it's 64-bit DWARF.
