and test that the opt was applied.

Needed to detect the right broadcast pattern.

Fix the case where local_subtensor_of_alloc wasn't computing the right broadcastable. It was due to a wrong broadcastable in Subtensor.make_node()

This easy debugging as we don't always know the object type.

Gh 1122

Fix tests crash in DebugMode recently introduced.

Now we keep the original error message type and just add more information to it.

Make a tests more robust to different seed

code cleanup

The error is due to rounding difference. The test that fail randomly is theano/sandbox/cuda/tests/test_conv_cuda_ndarray.py:TestConv2DGPU.test_logical_shapes.

Normally, we should set atol depending of the input shape, but the current structure don't allow this, so I use the output shape. So this could happen with other tests if the output shape is smaller.

Remove duplicate code, it is done in the imported test_basic_op

New backend: GpuCrossentropySoftmaxArgmax1HotWithBias, GpuCrossentropySoftmax1HotWithBiasDx

Remove duplicate computation and compilation.

Fix the final stuff.

As a side effect don't always loop over user provided cxx flags always when it contain march.

Make DebugMode raise a better error when an optimization insert an op

Py24

Fix gradient of split when there are disconnected outputs

This should fix gh-1589
