The tests use large arrays that need likely to be spilled. In order to check
correct spilling of all components actually use all components in the test.
v2: - use uniforms to pass the test values to make it more likely that the

to the array elements is done
This test verifies that the register merge step keeps a register alive
for the whole loop if at the beginning of this loop at least one component
is written unconditionally, and later another component is written
conditionally within the same loop, and the last read to the register also
happens

The test must achieve two things: On one hand, at least one component
of a temporary register must be written first at the beginning of the
Hello all,
this is my first message to the list. About the patch below:

"This test verifies whether the optimizer, and here specifically
the register merge step keeps the according register for the whole

I created the test proposing a new register merge algorithm.
