* glsl: add temporary copy_shader_info() functionTimothy Arceri2016-10-264-46/+88
| | | | | | | | | | | | | This function is added here to ease refactoring towards using the new shared shader_info. Once refactoring is complete and values are set directly it will be removed. We call it from _mesa_copy_linked_program_data() rather than glsl_to_nir() so that the values will be set for all drivers. In order to do this some calls need to be moved around so that we make sure to call do_set_program_inouts() before _mesa_copy_linked_program_data() Reviewed-by: Jason Ekstrand <[email protected]>

* 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.

* glsl: fail compilation of compute shaders when unsupportedIago Toral Quiroga2016-10-171-0/+13
| | | | | | | | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Just generate an __intrinsic_atomic_add with a negated parameter. Some background on the non-obvious reasons for the the big change to builtin_builder::call()... this is cribbed from some discussion with Ilia on mesa-dev. Why change builtin_builder::call() to allow taking dereferences and create them here rather than just feeding in the ir_variables directly? The problem is the neg_data ir_variable node would have to be in two lists at the same time: the instruction stream and parameters. The ir_variable node is automatically added to the instruction stream by the call to make_temp. Restructuring the code so that the ir_variables could be in parameters then move them to the instruction stream would have been pretty terrible. ir_call in the instruction stream has an exec_list that contains ir_dereference_variable nodes. The builtin_builder::call method previously took an exec_list of ir_variables and created a list of ir_dereference_variable. All of the original users of that method wanted to make a function call using exactly the set of parameters passed to the built-in function (i.e., call __intrinsic_atomic_add using the parameters to atomicAdd). For these users, the list of ir_variables already existed: the list of parameters in the built-in function signature. This new caller doesn't do that. It wants to call a function with a parameter from the function and a value calculated in the function. So, I changed builtin_builder::call to take a list that could either be a list of ir_variable or a list of ir_dereference_variable. In the former case it behaves just as it previously did. In the latter case, it uses (and removes from the input list) the ir_dereference_variable nodes instead of creating new ones. text data bss dec hex filename 6036395 283160 28608 6348163 60dd83 lib64/i965_dri.so before 6036923 283160 28608 6348691 60df93 lib64/i965_dri.so after Signed-off-by: Ian Romanick <[email protected]> Acked-by: Ilia Mirkin <[email protected]>

* nir/spirv/cfg: Use a nop intrinsic for tagging the ends of blocksJason Ekstrand2016-10-032-4/+6
| | | | | | | | | | | | | | | | | | | | | Previously, we were saving off the last nir_block in a vtn_block before moving on so that we could find the nir_block again when it came time to handle phi sources. Unfortunately, NIR's control flow modification code is inconsistent when it comes to how it splits blocks so the block pointer we saved off may point to a block somewhere else in the shader by the time we get around to handling phi sources. In order to get around this, we insert a nop instruction and use that as the logical end of our block. Since the control flow manipulation code respects instructions, the nop will keeps its place like any other instruction and we can easily find the end of our block when we need it. This fixes a bug triggered by a couple of vkQuake shaders.

* nir: Add a nop intrinsicJason Ekstrand2016-10-031-0/+3
| | | | | | | | | | | This intrinsic has no destination, no sources, no variables, and can be eliminated. In other words, it does nothing and will always get deleted by dead code elimination. However, it does provide a quick-and-easy way to temporarily tag a particular location in a NIR shader.

* nir/spirv/cfg: Detect switch_break after loop_break/continueJason Ekstrand2016-10-011-2/+2
| | | | | | | | | | | While the current CFG code is valid in the case where a switch break also happens to be a loop continue, it's a bit suboptimal. Since hardware is capable of handling the continue as a direct jump, it's better to use a continue instruction when we can than to bother with all of the nasty switch break lowering.
