* nir: add vs_inputs_dual_locations compiler optionTimothy Arceri2018-01-301-5/+9
| | | | | | | | | | | | | Allows nir drivers to either use a single or dual locations for vs double inputs. i965 uses dual locations for both OpenGL and Vulkan drivers, for now gallium OpenGL drivers only use a single location. The following patch will also make use of this option when calling nir_shader_gather_info(). Reviewed-by: Karol Herbst <[email protected]>
* compiler: tidy up double_inputs_read usesTimothy Arceri2018-01-302-5/+6
| | | | | | | | | | | | | First we move double_inputs_read into a vs struct in the union, double_inputs_read is only used for vs inputs so this will save space and also allows us to add a new double_inputs field. We add the new field because c2acf97fcc9b changed the behaviour of double_inputs_read, and while it's no longer used to track actual reads in i965 we do still want to track this for gallium drivers.

* glsl/linker: link-error using the same name in unnamed block and outsideJuan A. Suarez Romero2018-01-161-0/+23
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | According with OpenGL GLSL 4.20 spec, section 4.3.9, page 57: "It is a link-time error if any particular shader interface contains: - two different blocks, each having no instance name, and each having a member of the same name, or - a variable outside a block, and a block with no instance name, where the variable has the same name as a member in the block." This means that it is a link error if for example we have a vertex shader with the following definition. "layout(location=0) uniform Data { float a; float b; };" and a fragment shader with: "uniform float a;" As in both cases we refer to both uniforms as "a", and thus using glGetUniformLocation() wouldn't know which one we mean.

* meson: Use dependencies for nirDylan Baker2018-01-111-1/+2
| | | | | | | | | | | | | | | | | This creates two new internal dependencies, idep_nir_headers and idep_nir. The former encapsulates the generation of nir_opcodes.h and nir_builder_opcodes.h and adding src/compiler/nir as an include path. This ensures that any target that needs nir headers will have the includes and that the generated headers will be generated before the target is build. The second, idep_nir, includes the first and additionally links to libnir. This is intended to make it easier to avoid race conditions in the build when using nir, since the number of consumers for libnir and it's headers are quite high.

* glsl: disable vec3 packing/splitting in tfb separate modeBrian Paul2017-12-201-1/+13
| | | | | | | | | | | | | | | | This fixes a varying packing issue when using transform feedback in GL_SEPARATE_ATTRIBS mode. By time we get to linking, we already know that the number of feedback attributes is under the GL_MAX_TRANSFORM_FEEDBACK_SEPARATE_ATTRIBS limit so packing isn't as critical. In fact, packing/splitting vec3 attributes can cause trouble because splitting effectively creates another TFB output which can exceed device limits. So, disable vec3 packing when it's not needed to avoid that issue. Fixes the Piglit ext_transform_feedback-separate test on VMware driver. Reviewed-by: Timothy Arceri <[email protected]>

| | | | | | | | | | | | | | | | | | | The ARB_get_program_binary extension requires that uniform values in a program be restored to their initial value just after linking. This patch saves off the initial values just after linking. When the program is restored by glProgramBinary, we can use this to copy the initial value of uniforms into UniformDataSlots. V2 (Timothy Arceri): - Store UniformDataDefaults only when serializing GLSL as this is what we want for both disk cache and ARB_get_program_binary.

The corresponding GL types for half floats were reused from the AMD_gpu_shader_half_float extension. The int16 and uint16 types come from NV_gpu_shader_5 extension. This adds the builtins and the lexer support. To avoid a bunch of warnings due to cases not handled in switch, the new types have been added to a few places using same behavior as their 32-bit counterparts, except for a few trivial cases where they are already handled properly.

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.
