Unwritten shader output variables crash #862

Closed GoogleCodeExporter closed 9 years ago

GoogleCodeExporter commented 9 years ago 
If one binds a render target but does not write to it in the shader, ANGLE 
crashes in DynamicHLSL::FindOutputAtLocation when it tries to match each output 
to a shader variable.

AFAIK the colour of an unwritten output variable is undefined in GL and this is 
an application mistake however ANGLE should not crash either.

This patch ignores any output which is not written by the shader while 
generating the HLSL.

Closing, as fix is landed.
