[require]
shader model >= 4.0

% Let's try to mismatch the shader target output with the RTV type in various
% ways. All of them appears to be valid: the bits are copied as-is, without
% being interpreted. Excessive bits are discarded, missing bits are left
% undefined. The warnings emitted by the native validator suggest that it is
% not an error to rely on these behaviours.
