Re: RFC: GOLD: Add support for MEMORY regions in linker scripts

[Nick Clifton <nickc at redhat dot com>]

Hi Ian,

  Thanks for the review of my original patch.  Attached is a revised 
one which I hope addresses all of the issues that you raised.  I have 
also added some more error checking, and an entry in the testsuite.

  What do you think - is the patch suitable for committing to the sources ?

Cheers
  Nick
