Question about "gnu.linkonce.wi." sections

["Ivan Pantushev" <ipantushev@iname.com>]

Hello,

I am decoding the debugging information in an Elf/Dwarf_2 file and there are references to type information in ".gnu.linkonce.wi.*" sections which I don't know how to resolve (binutils 2.16.1 and gcc 4.0.2 were used).

Here is a part of the ".debug_info" section:
   Compilation Unit @ 0:
    Length:        79
    Version:       2
    Abbrev Offset: 0
    Pointer Size:  4
  <0><b>: Abbrev Number: 1 (DW_TAG_compile_unit)
      DW_AT_stmt_list   : 0
      DW_AT_low_pc      : 0x100000
      DW_AT_high_pc     : 0x100090
      DW_AT_name        : startup.gas
      DW_AT_comp_dir    : d:\test
      DW_AT_producer    : GNU AS 2.16.1
      DW_AT_language    : 32769	(MIPS assembler)
   Compilation Unit @ 53:
    Length:        235
    Version:       2
    Abbrev Offset: 20
    Pointer Size:  4
  <0><5e>: Abbrev Number: 3 (DW_TAG_compile_unit)
      DW_AT_macro_info  : 0
      DW_AT_stmt_list   : 98
      DW_AT_high_pc     : 0x100090
      DW_AT_low_pc      : 0x100090
      DW_AT_producer    : GNU C 4.0.2 -g
      DW_AT_language    : 1	(ANSI C)
      DW_AT_name        : board.c
      DW_AT_comp_dir    : d:\test
  - - -
  <1><c2>: Abbrev Number: 6 (DW_TAG_array_type)
      DW_AT_sibling     : <d2>
      DW_AT_type        : <#19>

The last DW_AT_type references type information at offset 0x19, but there is no such information in the .debug_info section.

There are 18 ".gnu.linkonce.wi.FILENAME.h.*" sections and there is a type info at offset 19 in each of them (instead of * there is a hexadecimal number like b10c314a for example).

How do I find out which ".gnu.linkonce.wi.FILENAME.h.*" section is the one to be used for the type information (of the array type at offset 0xc2 in the ".debug_info" section)?

Thank you for your time.

Greetings,
Ivan Pantushev
