: There is a confusion in bfd and gdb about addr_size.
: In _bfd_dwarf2_find_nearest_line(), the 'addr_size' corresponds to the
: ELF format size: 4 for ELF32 and 8 for ELF64. It is used to represent
: size/offset/index within the ELF sections.
: This 'addr_size' has nothing to do with the address size of the target 
: specified by the DW_AT_address_class. It should better be named
: 'elf_addr_size'
: or something like this.

Thanks for the explanation.

Umm - your patch does not include any modification to

But it does include a modification to parse_comp_unit, which is not

However that is just nitpiking, I can pick the correct ChangeLog entry
up from your previous patch.

So I think the patch is OK now, and I will check it in for you.
