* glsl: Simplify the built-in function linking code.Kenneth Graunke2013-12-011-20/+22
| | | | | | | | | | | | | | | | | | Previously, we stored an array of up to 16 additional shaders to link, as well as a count of how many each shader actually needed. Since the built-in functions rewrite, all the built-ins are stored in a single shader. So all we need is a boolean indicating whether a shader needs to link against built-ins or not. During linking, we can avoid creating the temporary array if none of the shaders being linked need built-ins. Otherwise, it's simply a copy of the array that has one additional element. This is much simpler. This patch saves approximately 128 bytes of memory per gl_shader object. Signed-off-by: Kenneth Graunke <[email protected]> Reviewed-by: Ian Romanick <[email protected]>
* glsl/linker: Validate IR just before reparenting.Paul Berry2013-11-261-0/+5
| | | | | | | | | | | | | | | | | If reparent_ir() is called on invalid IR, then there's a danger that it will fail to reparent all of the necessary nodes. For example, if the IR contains an ir_dereference_variable which refers to an ir_variable that's not in the tree, that ir_variable won't get reparented, resulting in subtle use-after-free bugs once the non-reparented nodes are freed. (This is exactly what happened in the bug fixed by the previous commit). This patch makes this kind of bug far easier to track down, by transforming it from a use-after-free bug into an explicit IR validation error.

* glsl: Fix interstage uniform interface block link error detection.Paul Berry2013-11-211-2/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | | Previously, we checked for interstage uniform interface block link errors in validate_interstage_interface_blocks(), which is only called on pairs of adjacent shader stages. Therefore, we failed to detect uniform interface block mismatches between non-adjacent shader stages. Before the introduction of geometry shaders, this wasn't a problem, because the only supported shader stages were vertex and fragment shaders, therefore they were always adjacent. However, now that we allow a program to contain vertex, geometry, and fragment shaders, that is no longer the case. Fixes piglit test "skip-stage-uniform-block-array-size-mismatch".

| | | | | | | | | | | | | | | | | | I made this a function (instead of a method of ir_variable) because it made the change set smaller, and I expect that there will be an overload that takes an ir_var_mode enum. Having both functions used the same way seemed better. v2: Add missing case for ir_var_system_value. v3: Change the ir_var_mode_count case to just break. Move the assertion and the return outside the switch-statment.

* glsl/gs: Fix transform feedback of gl_ClipDistance.Paul Berry2013-10-241-0/+2
| | | | | | | | | | | | | | | | | | | | | | Since gl_ClipDistance is lowered from an array of floats to an array of vec4's during compilation, transform feedback has special logic to keep track of the pre-lowered array size so that attempting to perform transform feedback on gl_ClipDistance produces a result with the correct size. Previously, this special logic always consulted the vertex shader's size for gl_ClipDistance. This patch fixes it so that it uses the geometry shader's size for gl_ClipDistance when a geometry shader is in use. Fixes piglit test spec/glsl-1.50/transform-feedback-type-and-size. v2: Change the type of LastClipDistanceArraySize to "unsigned", and clarify the comment above it.

* glsl: Simplify the interface to link_invalidate_variable_locationsIan Romanick2013-10-221-24/+24
| | | | | | | | | | | | | | | | | | | | | | | | | | | The unit tests added in the previous commits prove some things about the state of some internal data structures. The most important of these is that all built-in input and output variables have explicit_location set. This means that link_invalidate_variable_locations doesn't need to know the range of non-generic shader inputs or outputs. It can simply reset location state depending on whether explicit_location is set. There are two additional assumptions that were already implicit in the code that comments now document. - ir_variable::is_unmatched_generic_inout is only used by the linker when connecting outputs from one shader stage to inputs of another shader stage. - Any varying that has explicit_location set must be a built-in. This will be true until GL_ARB_separate_shader_objects is supported. As a result, the input_base and output_base parameters to link_invalidate_variable_locations are no longer necessary, and the code for resetting locations and setting is_unmatched_generic_inout can be simplified.

* glsl/linker: Allow mixing of desktop GLSL versions.Paul Berry2013-10-211-7/+3
| | | | | | | | | | | | | | | | | | | | | | | | | Previously, Mesa followed the linkage rules outlined in the GLSL 1.20-1.40 specs, which (collectively) said that GLSL versions 1.10 and 1.20 could be linked together, but no other versions could be linked. In GLSL 4.30, the linkage rules were relaxed so that any two desktop GLSL versions can be linked together. This change was made because it reflected the behaviour of nearly all existing implementations (see Khronos bug 8463). Mesa was one of the few (perhaps the only) exceptions to prohibit cross-linking of some GLSL versions. Since the GLSL linkage rules were deliberately relaxed in order to match the behaviour of existing implementations, it seems appropriate to relax the rules in Mesa too (even though Mesa doesn't support GLSL 4.30 yet). Note that linking ES and desktop shaders is still prohibited, as is linking ES shaders having different GLSL versions. Fixes piglit tests "shaders/version-mixing {interstage,intrastage}".

| | | | | | | | | | | | | | | | | | | | | | | During compilation, we'll use this to determine built-in availability. The plan is to have a single shader containing every built-in in every version of the language, but filter out the ones that aren't actually available to the shader being compiled. At link time, we don't actually need this filtering capability: we've already imported prototypes for every built-in that the shader actually calls, and they're flagged as is_builtin(). The linker doesn't import any additional prototypes, so it won't pull in any unavailable built-ins. When resolving prototypes to function definitions, the linker ensures the values of is_builtin() match, which means that a shader can't trick the linker into importing the body of an unavailable built-in by defining a suspiciously similar prototype. In other words, during linking, we can just pass in NULL. It will work out fine.

| | | | | | | | | | | | | | | | | | | | | | | | | | | This patch extracts the following logic from validate_vertex_shader_executable(): (a) Generate an error if the shader writes to both gl_ClipDistance and gl_ClipVertex. (b) Record whether the shader writes to gl_ClipDistance in gl_shader_program for use by the back-end. (c) Record the size of gl_ClipDistance in gl_shader_program for use by transform feedback logic. And moves it into a function that is shared between vertex and geometry shaders. Strictly speaking we only need to have shared logic for (b) and (c) right now (since (a) only matters in compatibility contexts, and we're only implementing geometry shaders in core contexts right now).

In essence, those rules boil down to the following: - If an input array declaration does not specify a size, and it follows an input layout declaration, it is sized according to the input layout. - If an input layout declaration follows an input array declaration that didn't specify a size, the input array declaration is given a size at the time the input layout declaration appears. - All input layout declarations and input array sizes must ultimately match. Inconsistencies are reported as soon as they are detected, at compile time if the inconsistency is within one compilation unit, otherwise at link time. - At least one compilation unit must contain an input layout declaration.

* mesa: Disable validate_ir_tree() on release builds.Eric Anholt2013-03-251-2/+0
| | | | | | | | | Since half of ir_validate uses asserts() (the other using printf() then abort()), there's not much use to calling it in a release build. Cuts 6.3% of the startup time of TF2. NOTE: This is a candidate for the stable branches. Reviewed-by: Kenneth Graunke <[email protected]>

* mesa/glsl: Separate parsing logic from _mesa_get_uniform_location.Paul Berry2013-02-041-0/+59
| | | | | | | | | | | | | | | | The parsing logic is moved to a new function in the GLSL module, parse_program_resource_name(). This name was chosen because it should eventually be useful for handling everything that OpenGL 4.3 calls "program resources" (e.g. uniforms, vertex inputs, fragment outputs, and transform feedback varyings). Future patches will make use of this function for linking transform feedback varyings. NOTE: This is a candidate for the 9.1 branch.

* glsl: Calculate UBO data at link-timeIan Romanick2013-01-251-18/+5
| | | | | | | | | | | | | Use the function added in the previous commit. This temporarily causes gles3conform uniform_buffer_object_index_of_not_active_block, uniform_buffer_object_inherit_and_override_layouts, and uniform_buffer_object_repeat_global_scope_layouts to assertion fail. This is fixed in the next commit. Signed-off-by: Ian Romanick <[email protected]> Reviewed-by: Jordan Justen <[email protected]>
