Linking to Gt.m object files

2012-02-22 Thread Mike Dupont

I have done a s imple experiment with trying binutils on the a gt.m binary

I would like to work on getting objtools to support these binaries,
and the objdump works, but the linker fails.
Attached is a mini program that just calls some internal routine and
the object file produced by it.

GTM compiles the source code to obj files and loads them into memory,

Hi Guys,

  Alan's patch is better than mine, so I have checked it in, along with a new
linker testcase and some tweaks to the cris linker tests that were affected. 
(No other target showed regressions because of this patch).

Cheers
  Nick
