[PATCH] MSP430: Support relocations for subtract expressions in .uleb128 directives

[Nick Clifton]

Hi Jozef,

  I have a few questions/comments about this patch:

  * Have these new relocations been agreed with TI ?
    Ie are they now part of the MSP430 EABI ?  If not, then
    they probably ought to include "GNU" as part of their names...

  * Paranoia here:  The write_uleb128() function really should
    take an end pointer parameter, and check to make sure that it
    is not overwritten.  I know that you do check the return pointer
    in the code, but I would not be at all surprised that a fuzzed
    MSP430 binary could persuade the new code to write beyond the
    end of the section buffer.

    Also the function should be renamed to _bfd_write_uleb128
    (or something similar) and moved into bfd/elf-eh-frame.c.
    It is a generic function after all, and should live with the
    other LEB128 functions.

Other than that though the patch looks good to me.

Cheers
  Nick
