Description Tom Tromey 2024-02-09 18:57:56 UTC 
I noticed today that DW_IDX_die_offset is documented
as having a reference form, but right now gdb emits
it as:

		m_abbrev_table.append_unsigned_leb128 (DW_IDX_die_offset);
		m_abbrev_table.append_unsigned_leb128 (DW_FORM_udata);

this should probably be DW_FORM_sec_offset

Setting the target milestone here because this code is new
and so we can fix it before it is visible in a release.
Comment 2 Tom Tromey 2024-02-10 00:36:57 UTC 
DW_FORM_ref_addr is better I think.

    Use DW_FORM_ref_addr for DIE offset in .debug_names
    
    Today I realized that while the .debug_names writer uses DW_FORM_udata
    for the DIE offset, DW_FORM_ref_addr would be more appropriate here.
    This patch makes this change.
