Hello,
Giuliano Procida <gprocida@google.com> a écrit:
> PR28060 - Invalid offset for bitfields
I have put this as the summary of the patch to searching in the commit
logs by bug number.
>
> Bitfield and other member offsets can be specified in DWARF using:

> - DW_AT_data_bit_offset, or
> - DW_AT_data_member_location and optionally DW_AT_bit_offset.
>
> The code would only use the value DW_AT_data_member_location if there
> was no DW_AT_bit_offset. This commit fixes this and adjusts
> documentation and affected tests.
