Re: How to lookup a symbol for vma using BFD?

["Dmitry Smirnov" <divis1969 at gmail dot com>]

Thank you, this was very helpful.

I've borrowed the code from objdump.c and it works fine, I can find
the symbol I want.

But for some reason I cannot find a filename/line info using
bfg_find_line() for that symbol.

I've found that the comp unit for this file contains no
DW_AT_stmt_list attribute and comp_unit_maybe_decode_line_info() from
dwarf2.c returns FALSE thus preventing comp_unit_find_line() from
looking up variable table.

In fact, for now I'm interesting in filename only but I cannot find a
way to retrieve it. I can try, of course to build my "special BFD lib,
but perhaps there is some standard way?
