Sorry, I can not finish the qemu test within this month. The reason is
my tilegx qemu is still lack of some instructions implementation, next,
I should finish them firstly (I implemented most insns, but not all).

                  === gcc Summary ===
  
  # of expected passes            69830
  # of unexpected failures        4312
  # of unexpected successes       2
  # of expected failures          108
  # of unresolved testcases       1776
  # of unsupported tests          1567

More than 4K failures are because tilegx qemu lacks of instruction's
implementation, and also more than 10 issues are for TIMEOUT (I guess,
my original tilegx qemu instruction's implementation still has bugs).

I shall try to finish it within next month, although I am not quite sure
(it needs enough time resources on it, but I am lack of time resources:
I can only spend less 1 hour per work day and 2 hours per week end day).



Thanks.

A qemu port for tile hardware would certainly be welcome, but to my knowledge, no one has completed such a port yet.  ISA and ABI documentation for tilegx are available at www.tilera.com/scm.
