[Piglit] [PATCH] arb_shader_image_load_store/shader-mem-barrier: Add explicit memoryBarrier to volatile subtest.

This makes sure that reads and writes of the volatile-qualified images occur in the expected order. It's unclear whether the GLSL volatile qualifier was intended to have the required memory ordering implications as it does in C. I've bugged Khronos about it [1], but because I haven't seen any

[Piglit] [PATCH] ARB_texture_multisample: Don't use a 3D texture size above the minmax.

For GL 3.1, the minmax is 256, and for GL 2.1 it's only 16. We don't put anything in the texture, so we can just use 16. --- tests/spec/arb_texture_multisample/teximage-3d-multisample.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git

[Piglit] [PATCH] getteximage-depth: Fix failures on cubemap-supporting GL < 3.0.

You don't get to specify depth cubes until 3.0 (GL_EXT_gpu_shader4 merge). --- tests/texturing/getteximage-depth.c | 3 ++- 1 file changed, 2 insertions(+), 1 deletion(-) diff --git a/tests/texturing/getteximage-depth.c b/tests/texturing/getteximage-depth.c index 97977138e9d2..2986962631c6
