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
