[Dwarf-Discuss] How to get union member offset?

[Jun Koi]

Hi,

I am trying to get the offset of a member in an union. However, there
is no attribute DW_AT_data_member_location attached to it!

I heard that we can get the offset of the container union instead (the
union is a member of another struct). But how can we get the
container?

I use objdump to see the information, and information attached to my
union's member is only:
- DW_AT_name
- DW_AT_decl_file
- DW_AT_decl_line
- DW_AT_type

Thank you a lot,
Jun
