* spirv: Add vtn_fail and vtn_assert helpersJason Ekstrand2017-12-042-0/+67
| | | | | | | | | | | | | These helpers are much nicer than just using assert because they don't kill your process. Instead, it longjmps back to spirv_to_nir(), cleans up all the temporary memory, and nicely returns NULL. While crashing is completely OK in the Vulkan world, it's not considered to be quite so nice in GL. This should help us to make SPIR-V parsing much more robust. The one downside here is that vtn_assert is not compiled out in release builds like assert() is so it isn't free.

* spirv: Rework loggingJason Ekstrand2017-12-044-18/+119
| | | | | | | | | | | | | | | | This commit reworks the way that logging works in SPIR-V to provide richer and more detailed logging infrastructure. This commit contains several improvements over the old mechanism: 1) Log messages are now more detailed. They contain the SPIR-V byte offset as well as source language information from OpSource and OpLine. 2) There is now a logging callback mechanism so that errors can get propagated to the client through debug callbak extensions.

| | | | | | | | | | | | | | | | | an array We validate that the interface block array type's definition matches. However, previously, the function could be called if an non-array interface block has different type definitions -for example, when the precision qualifier differs in a GLSL ES shader, we would create two different types-, and it would return invalid as both definitions are non-arrays. We fix this by specifying that at least one definition should be an array to call the validation.

* spirv: Use correct type for sampled imagesAlex Smith2017-11-133-6/+6
| | | | | | | | | | | | | | | | | | | | | | We should use the result type of the OpSampledImage opcode, rather than the type of the underlying image/samplers. This resolves an issue when using separate images and shadow samplers with glslang. Example: layout (...) uniform samplerShadow s0; layout (...) uniform texture2D res0; ... float result = textureLod(sampler2DShadow(res0, s0), uv, 0); For this, for the combined OpSampledImage, the type of the base image was being used (which does not have the Depth flag set, whereas the result type does), therefore it was not being recognised as a shadow sampler.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | According to the GLSL ES 3.20, GLSL 4.50, and GLSL 1.20 specs: "To force all output variables to be invariant, use the pragma #pragma STDGL invariant(all) before all declarations in a shader." Notably, this is only supposed to affect output variables. Furthermore, "Only variables output from a shader can be candidates for invariance." It looks like this has been wrong since we first supported the pragma in 2011 (commit 86b4398cd158024f6be9fa830554a11c2a7ebe0c). Fixes dEQP-GLES2.functional.shaders.preprocessor.pragmas.pragma_fragment. v2: Now that all cases are identical (other than compute shaders, which have no output variables anyway), we can drop the switch statement entirely. We also don't need the current_function == NULL check; this was a hold over from when we had a single var_mode_out for both function parameters and shader varyings, in the bad old days.
