Nothing - in fact I must apologise because when I reapplied your patch 
and regenerated the various files I then found that it built cleanly 
without any problems.  (I think that I must have mistakenly applied an 
older version of your patch last time.  Sorry).

There are now only two points that need to be addressed:

   1. ChangeLog entries for the various directories that are affected by 
the patch.

   2.  The GAS testsuite is showing two new failures for the score-elf 
toolchain:

    FAIL: gas/score/branch_32
    FAIL: gas/score/branch_32-lt

      Looking at the log these tests are failing because of error 
messages like this from the assembler:

   branch_32.s:162: Error: branch relocation truncate (0x244) [-2^9 ~ 2^9]

Point 1 is important - I need the changelogs before I can check your 
patch in.  Point 2 is less important - it could be fixed by a future 
patch if necessary, although it would be nice if the score7 port had no 
testsuite failures right from the start.

Cheers
