I don't really think so. I've already deleted a pile of these tests:
check git log tests/glean/tglsl1.cpp. It's usually a grep or two for
each set of tests to conclusively determine that we're already testing
I made a small list of categories of remaining tests and things we
should test in piglit a while back when looking through tglsl1.cpp
(i.e., things that aren't tested elsewhere):
Swizzles: swizzles can be .rgba/.xyzw/.stpq but not a mix of them.
Probably a generator to test all possible combinations? Or just some
parser tests would probably be sufficient.
Make sure to test swizzling expressions, e.g., (a + b).zyx
Writemasks: Maybe part of the previous generator
Nested function calls
a = b = c;
Short circuit evaluation
a && b -> set a = false. make b a function call with side-effects
a || b -> set a = true. ...
But most of the tglsl1.cpp tests can just be deleted outright.
