* glsl: Parse 'layout' as a token with advanced blending or bindlessKenneth Graunke2018-02-211-0/+2
| | | | | | | | | | | | | Both KHR_blend_equation_advanced and ARB_bindless_texture provide layout qualifiers, and are exposed in compatibility contexts. We need to parse the layout qualifier as a token in order for those to work, but forgot to extend this check. ARB_shader_image_load_store would need a similar treatment, but we don't expose that in legacy OpenGL contexts.

* nir: remove old assertTimothy Arceri2018-02-221-1/+0
| | | | | | | | | | | | This was originally intended to make sure the remap location was not -1. However the code has changed alot since then, the location is now never set to -1 and we also handle components meaning this old assert has been doing comparisions with the pointer to the array of component data.

* glsl/linker: check same name is not used in block and outsideJuan A. Suarez Romero2018-02-051-23/+30
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | According with OpenGL GLSL 3.20 spec, section 4.3.9: "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 fixes a previous commit 9b894c8 ("glsl/linker: link-error using the same name in unnamed block and outside") that covered this case, but did not take in account that precision qualifiers are ignored when comparing blocks with no instance name. With this commit, the original tests KHR-GL*.shaders.uniform_block.common.name_matching keep fixed, and also dEQP-GLES31.functional.shaders.linkage.uniform.block.differing_precision regression is fixed, which was broken by previous commit. v2: use helper varibles (Matteo Bruni) Fixes: 9b894c8 ("glsl/linker: link-error using the same name in unnamed block and outside") Bugzilla: https://bugs.freedesktop.org/show_bug.cgi?id=104668 Bugzilla: https://bugs.freedesktop.org/show_bug.cgi?id=104777 CC: Mark Janes <[email protected]> CC: "18.0" <[email protected]> Tested-by: Matteo Bruni <[email protected]> Reviewed-by: Tapani Pälli <[email protected]> Signed-off-by: Juan A.

| | | | | | | | | | | | | | | | | | | The materials are now moved to the end of the generic attributes block to the range 4-15. Before, the way the position and generic 0 attribute is handled was dependent on the presence and kind of the currently attached vertex program. With this change the way the position attribute and the generic 0 attribute is treated only depends on the enabled flag of those two arrays.

| | | | | | | | | | | | | | | | | | c2acf97fcc9b32e changed the use of double_inputs_read to be inconsitent with its previous meaning. Here we re-enable the gather info code that was removed as the modified code from c2acf97fcc9b32e now uses the double_inputs member rather than double_inputs_read. This change allows us to use double_inputs_read with gallium drivers without impacting double_inputs which is used by i965. We also make use of the compiler option vs_inputs_dual_locations to allow for the difference in behaviour between drivers that handle vs inputs as taking up two locations for doubles, versus those that treat them as taking a single location.

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.

| | | | | | | | | | | | | | | | | 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.
