commit 4d83bd9b6f5ccc4abd212ca5d6a6477cb52f78cc
Author: Mark Wielaard <mjw@redhat.com>
Date:   Mon Jul 5 21:14:42 2010 +0200

    Put generated debug_hdr in _stp_section, add sec_load_offset for adjustment.
    
    Make sure to adjust .debug_frame addresses to section load address.
    Which means keeping track of the (synthetic) .debug_frame_hdr index
    per section. For now keep track of "magic sections". Will need to
    be extended to track all loadable code sections as we do for symbol
    tables. See http://sourceware.org/ml/systemtap/2010-q3/msg00012.html
    
    * runtime/sym.h (_stp_module): Remove dwarf_module_base. Move debug_hdr
      and debug_hdr_len from here to ...
      (_stp_section): ... here. And add sec_load_offset.
    * runtime/unwind.c (adjustStartLoc): Don't use m->dwarf_module_base,
      use s->sec_load_offset.
      (_stp_search_unwind_hdr): Use s->debug_hdr and s->debug_hdr_len.
    * translate.cxx (create_debug_frame_hdr): Accept and set debug_frame_off.
      (get_unwind_data): Likewise.
      (dump_unwindsyms): Keep track of debug_frame_off. Output debug_frame_hdr
      per _stp_section if section is ".dynamic", ".absolute", ".text", or
      "_stext".
