* glsl: Add support for the framebuffer fetch layout(noncoherent) qualifier.Francisco Jerez2018-02-241-0/+1
| | | | | | | | | | This allows the application to request framebuffer fetch coherency with per-fragment output granularity. Coherent framebuffer fetch outputs (which is the default if no qualifier is present for compatibility with older versions of the EXT_shader_framebuffer_fetch extension) will have ir_variable_data::memory_coherent set to true.

* glsl: fix derived cs variablesIlia Mirkin2017-10-231-90/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | There are two issues with the current implementation. First, it relies on the layout(local_size_*) happening in the same shader as the main function, and secondly it doesn't work for variable group sizes. In both cases, the simplest fix is to move the setup of these derived values to a later time, similar to how the gl_VertexID workarounds are done. There already exist system values defined for both of the derived values, so we use them unconditionally, and lower them after linking is performed. While we're at it, we move to using gl_LocalGroupSizeARB instead of gl_WorkGroupSize for variable group sizes. Also the dead code elimination avoidance can be removed, since there can be situations where gl_LocalGroupSizeARB is needed but has not been inserted for the shader with main function. As a result, the lowering code has to insert its own copies of the system values if needed.

* glsl: add matrix layout information to interface block typesIago Toral Quiroga2016-10-241-0/+1
| | | | | | | | | | | | | | | | | | | | | | So far we have been checking that interface block definitions had matching matrix layouts by comparing the definitions of their fields, however, this does not cover the case where the interface blocks are defined with mismatching matrix layouts but don't define any field with a matrix type. In this case Mesa will not fail to link because none of the fields will inherit the mismatching layout qualifier. This patch fixes the problem in the same way we fixed it for packing layout information: we add the the layout information to the interface type and then we check it matches during the uniform block linking process. v2: Fix unit tests so they pass the new parameter to glsl_type::get_interface_instance() Fixes: dEQP-GLES31.functional.shaders.linkage.uniform.block.layout_qualifier_mismatch_3 Bugzilla: https://bugs.freedesktop.org/show_bug.cgi?id=98245 Reviewed-by: Nicolai Hähnle <[email protected]> (v1)

| | | | | | | | | | | | | | | | | | | built-in. gl_SecondaryFragColorEXT should have the same location as gl_FragColor for the secondary fragment color to be replicated to all fragment outputs. The incorrect location of gl_SecondaryFragColorEXT would cause the linker to mark both FRAG_RESULT_COLOR and FRAG_RESULT_DATA0 as being written to, which isn't allowed by the spec and would ultimately lead to an assertion failure in fs_visitor::emit_fb_writes() on my i965-fb-fetch branch. This should also fix the code below for multiple dual-source-blended render targets, which no driver currently supports but we have plans to enable eventually in the i965 driver (the comment saying that no hardware will ever support it seems rather hilarious).

* glsl: Define a gl_LastFragData built-in for older GLSL versions.Francisco Jerez2016-08-241-0/+10
| | | | | | | | | | | | | | | | | | | | | | | The EXT_shader_framebuffer_fetch extension defines alternative language for GLES2 shaders where user-defined fragment outputs are not allowed. Instead of using inout user-defined fragment outputs the shader is expected to read from the gl_LastFragData built-in array. In addition this allows using the same language on desktop GLSL versions prior to 4.2 that support the deprecated gl_FragData built-in in preparation for the MESA_shader_framebuffer_fetch desktop GL extension. Both legacy and user-defined inout outputs have a common representation at the GLSL IR level, so it shouldn't make any difference for optimization passes and back-ends whether the application is using gl_LastFragData or user-defined outputs, all they'll see is a variable dereference of a fragment output at a certain interface location with the fb_fetch_output bit set to one. v2: Don't define the built-in variable on GLSL versions for which gl_FragData exists but is deprecated.

Beyond the GLSL front-end, talking about "interpolation modes" seems more natural than "interpolation qualifiers" - in the IR, we're removed from how exactly the source language specifies how to interpolate an input. Also, SPIR-V calls these "decorations" rather than "qualifiers".
