Testing xscale-elf{,-mbig-endian}{,-mthumb} I get two differences:


gdb.base/break.exp: backtrace while in called function
This starts passing for -mthumb!


gdb.c++/virtfunc.exp: print pEe->D::vg
This, and a few others disappear for -mthumb.  What is really happening 
is that the earlier test:
   print pDe->vg()
   FAIL: gdb.c++/virtfunc.exp: print pDe->vg() (timeout)
has caused the target to go for a walk (occures with old and new). 
Since the stack for the two test cases are slightly different, the exact 
walk (I think) varies leading to the differences.  The modified target 
eventually aborts when it runs out of memory.

Thoughts?
