2022-06-23arb_blend_func_extended: add GL_ARB_ES2_compatibility supportVasily Khoruzhick1-7/+39

2022-05-31Don't check for OpenGL 1.1Ian Romanick1-1/+0
Seriously. The Linux OpenGL ABI has always required at least OpenGL 1.2. The Windows OpenGL ABI has always required at least OpenGL 1.1. I don't know what the Mac OS X ABI requires, but every supported device has had 1.1 at least as far back as 10.5.8. SGI O2 and Octane support at least OpenGL 1.1. I don't think piglit needs to fail gracefully on systems from before 1996.

2022-05-31Fix many incorrect GLSL checksIan Romanick30-29/+44
piglit_require_GLSL() only checks that shader objects and the shading language exist. It does *NOT* check that any particular shader stage exists. It is perfectly valid to have an OpenGL 1.5 implementation that has only vertex shaders or only fragment shaders. piglit_require_GLSL_version(110) and piglit_require_GLSL_version(120) have the same failings as piglit_require_GLSL() and more. GLSL 1.10 is the minimum GLSL version that actually exists, so anything that has GLSL has version 1.10. GLSL 1.20 can be exposed by any implementation, so checking that version doesn't guarantee anything either. GLSL 1.30 implicitly requires OpenGL 3.0, so that is a strong check. All of the non-shader drivers in Mesa advertise shader objects and GLSL 1.20 and NEITHER vertex nor fragment stages. This fixes these tests to just skip on those drivers.

From section 5.7 "Structure and Array Operations" of the GLSL 1.30 spec: "Behavior is undefined if a shader subscripts an array with an index less than 0 or greater than or equal to the size the array was declared with." The behaviour becomes defined only in robustness extensions, however even if driver is technically allowed to crash or hang, it most likely doesn't want to. Robustness extensions encourage to us to return zero on out-of-bounds read, however it's not clearly applicable to the array of opaque types. What will happen when we call a built-in function which expects the opaque type with the instance returned from oob access?
