Right now, the idea behind the --glsl option is not getting two tests
from the same executable. The tests included with this series are
expected to run on SPIR-V mode. So for example, we would not add a new
entry on opengl.py/shader.py to run those tests twice. As mentioned it
is mostly a debug utility/sanity check, that was useful when we were
working on getting them passed, so we understand that will be still
useful on the future, for any other driver interested on support the
extension, or even for i965 again, if there is any future regression.
Perhaps you are thinking that we plan to use that option, or similar, to
reuse tests from other extensions. What I called "borrowed tests" on the
RFC I sent some months ago. For that case, our plan would be generate
new tests to be placed under generated_tests. So in the case of reusing
tests from other extensions, we would still have two different base
tests (one for GLSL, other for SPIRV).
