Speculative thoughts on using  a script to define what
DWARF? to write out in an elf file:

Syntax for dw tab entry
# is comment
levels by indentation like python
attrs.   indent to the tag they apply to.

;section  x
;endsection x

:label:
 [<level>] tag
	attr  [form name]  value

any attr or tag may have a label.

Various forms require specific value formats.
values sometims require offsets such as a sibling ref
or a fwd/rev ref or  a ref to the debug_loc sec


DW_FORM_data 1,2 integer
DW_FORM_data 4,8  integer or offset depends on context
DW_FORM_sdata, udata integer
DW_FORM_string  "string value"
DW_FORM_strp    "string value"
DW_FORM_block 1,2,4,8  blk-fmt

     this is blk_fmt
	hex number
	decimal number
	[ dw-expr]
	

sythetic forms:
DW_FORM_loclist  [label | loclist-itself]

loclist-itself
	offset  offset  DW_FORM_block<n> [blk_fmt]
	...

DW_FORM_maclist   label
DW_FORM_?

Line table entries

CIE entries

FDE entries


mac  sec entries
