Hi Mark,

  I have uploaded a possible patch to LD for this problem.  I assume that a
similar patch to GOLD will also be possible, but I have not looked into this
yet.  

  In the course of checking the patch I found one linker testcase that broke:
default-script2.  Looking at the test, it seems to me that the patched linker
is actually correct in this instance.  The test uses a linker script that looks
like this:

  _START = DEFINED(_START) ? _START : 0x9000000;
  SECTIONS
  {
    . = _START;
    .text : {*(.text)}
    /DISCARD/ : {*(*)}
  }

It then checks to see that the .text symbol has been given an address of
0x90000000 despite the fact that "-defsym _START=0x8000000" has been passed on
the command line.  The patched linker sets the address to 0x80000000, which I
think is right.

  Does anyone have any comments before I look at creating a patch for GOLD ?

Cheers
  Nick
