Re: Why doesn't objdump display assembly code mixed with source code?

[Nick Clifton <nickc at redhat dot com>]

Hi PRC,

> I change the linker script to:

There are two problems with your amended linker script:

  1.  It does not include all of the DWARF2 debugging sections.
      In particular the .debug_loc section is missing which is
      needed in order for objdump to be able to display the
      source code alongside the disassembly.

  2.  It allows the dwarf sections to be placed at non-zero
      address which corrupts their behaviour.

Please try the attached amended version of your script which should 
provide the desired results.

Cheers
