Disassemble binary with Debug info

Disassemble binary with Debug info

[Wombat]

Hello
I recently recovered an old ELF binary of mine which had been compiled 
(probably) with GCC2. Unfortunetally, I do not have the source code 
anymore, but the binary contains the debug information.Using objdump 
--debugging, I could get all my typedefs, however I'd like to view the 
the whole code. I would be very happy if anyone could point me to a 
Disassembler that uses the debug information to name variables, 
especially variables inside structs. objdump --disassemble does not seem 
to that.
So I'm kind of stuck, any help is welcome

Thank you

readelf --debug will do it, but the output is not easy to read.

If it really contains full debugging information, you can load it into 
gdb and use ptype and friends to print the definitions of all types.

Yeah, that's what I already got with objdump. It gave me all typedefs in 
one text file.
What I want is a Disassembler or Debugger that actually uses this 
information to make the assembler code more readable.
I mean, from the objdump output, I can see that the debug information 
holds all variable's names and their type. The types themselves (if 
custom) are also defined. Therefore, a disassembler could use that to 
make the code easier to read.
Do you see what I mean?
