* glsl: update default precision qualifier when it is set in the shaderSamuel Iglesias Gonsálvez2016-10-261-1/+4
| | | | | | | | | | | | Default precision qualifier for a data type could be set several times inside a shader. This patch allows to update the default precision qualifier for the given type that is saved in the symbol table. If it is not in the symbol table, just add it.

* nir: stop adjusting driver location for varying packingTimothy Arceri2016-10-262-47/+2
| | | | | | | | | | | | As of 59864e8e020 we just use the location assigned by the front-end and no longer need this for i965. Since there were some issues in the logic with assigning arrays the same driver location if they didn't start at the same location just remove it and let other drivers implement a solution if needed when they add ARB_enhanced_layouts support.

* glsl: add matrix layout information to interface block typesIago Toral Quiroga2016-10-248-12/+42
| | | | | | | | | | | | | | | | | | | | | | 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)
* glsl/mesa: remove unused namespace support from the symbol tableTimothy Arceri2016-10-242-11/+11
| | | | | | | | | | | | | | | | | | Namespace support seems to have been unused for a very long time. Previously the hash table entry was never removed and the symbol name wasn't freed until the symbol table was destroyed. In theory this could reduced the number of times we need to copy a string as duplicate names are reused. However in practice there is likely only a limited number of symbols that are the same and this is likely to cause other less than optimal behaviour such as the hash_table continuously growing. Along with dropping namespace support this change removes entries from the hash table as they become unused. Reviewed-by: Samuel Iglesias Gonsálvez <[email protected]>

* glsl: Indirect array indexing on non-last SSBO member must fail compilationIago Toral Quiroga2016-10-202-7/+15
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | After the changes in comit 5b2675093e863a52, we moved this check to the linker, but the spec expects this to be checked at compile-time. There are dEQP tests that expect an error at compile time and the spec seems to confirm that expectation: "Except for the last declared member of a shader storage block (section 4.3.9 “Interface Blocks”), the size of an array must be declared (explicitly sized) before it is indexed with anything other than an integral constant expression. The size of any array must be declared before passing it as an argument to a function. Violation of any of these rules result in compile-time errors. It is legal to declare an array without a size (unsized) and then later redeclare the same name as an array of the same type and specify a size, or index it only with integral constant expressions (implicitly sized)." Commit 5b2675093e863a52 tries to take care of the case where we have implicitly sized arrays in SSBOs and it does so by checking the max_array_access field in ir_variable during linking. In this patch we change the approach: we look for indirect access on SSBO arrays, and when we find one, we emit a compile-time error if the accessed member is not the last in the SSBO definition. There is a corner case that the specs do not address directly though and that dEQP checks for: the case of an unsized array in an SSBO definition that is not defined last but is never used in the shader code either. The following dEQP tests expect a compile-time error in this scenario: dEQP-GLES31.functional.debug.negative_coverage.callbacks.shader.compile_compute_shader dEQP-GLES31.functional.debug.negative_coverage.get_error.shader.compile_compute_shader dEQP-GLES31.functional.debug.negative_coverage.log.shader.compile_compute_shader However, since the unsized array is never used it is never indexed with a non-constant expression, so by the spec quotation above, it should be valid and the tests are probably incorrect.

| | | | | | | | | | | | | | | | | | | | | | | Generally, we only check for the presence of compute shaders during parsing when we find any language (like layout qualifiers) that are specific to compute shaders, however, it is possible to define an empty compute shader does not use any language specific to compute shaders at all and we should fail the compilation anyway. dEQP checks this. This patch adds a check for compute shader availability after we have parsed the source code. At this point we know the effective GLSL version and also extensions enabled in the shader. Fixes a subcase of the following dEQP tests: dEQP-GLES31.functional.debug.negative_coverage.callbacks.shader.compile_compute_shader dEQP-GLES31.functional.debug.negative_coverage.get_error.shader.compile_compute_shader dEQP-GLES31.functional.debug.negative_coverage.log.shader.compile_compute_shader The tests still fail because there is one more subcase that fails that needs another fix.
