Olli Etuaho 9733ceef 2017-05-11T19:14:35 Initialize uninitialized locals in GLSL output Guarantee that local variables are initialized before they are used in GLSL output. In HLSL output all variables were already being initialized. Locals are initialized using an AST transform. The local variable init can only be run after some simplification of the AST, so that it is able to handle complex cases like: for (int i[2], j = i[0]; i[0] < 3; ++i[0]) { } If we're dealing with ESSL 1.00 which lacks array constructors, in this kind of case the uninitialized array initialization code needs to be hoisted out of the loop init statement, and the code also needs to make sure that j's initializer is run after i is initialized. Another complex case involves nameless structs. This can be an issue also in ESSL 3.00 and above: for (struct { float f; } s; s.f < 1.0; ++s.f) { } Since the struct doesn't have a name, its constructor can not be used. We solve this by initializing the struct members individually, similarly to how arrays are initialized in ESSL 1.00. Initializing local variables is disabled on Mac and Android for now. On Mac, invalid behavior was exposed in the WebGL 2.0 tests when enabling it. On Android, the dEQP test runs failed for an unknown reason. Bugs have been opened to resolve these issues later.

Jamie Madill e794cd86 2017-01-13T17:29:51 Vulkan: Implement new GLSL translator back-end. The Vulkan GLSL translator back-end will handle validating and translating our WebGL/ESSL shaders into Vulkan-specific GLSL. glslang (the Vulkan one) accepts both GLSL and GLSL ES shaders as inputs, and both the desktop and ESSL back-ends give incompleteness warnings when used. For now, use the desktop GL 450 as a target for Vulkan GLSL. The Vulkan-specific changes are currently only to add locations to every vertex input and fragment output.

It can also be argued that perfect prevention of shader timing attacks is not feasible due to factors that are not under control of ANGLE, such as fixed function color compression in GPUs. Such color compression may make the use of texture bandwidth and thus performance dependent on the content of a texture regardless of whether a compressed format is chosen through the API.

The ParseContext is changed so that type qualifiers can be now joined together (i.e. like layout qualifiers). This will allow enumeration of multiple storage qualifiers (i.e. uniform readonly coherent) which is essential for support of ES31 features. Some of the error checks had to be moved closer to the root of the parse tree since some of the information about the expression might be missing. Unfortunately, as there is no explicit ordering imposed by the grammar, additional checks for proper order of qualifiers had to be added.

Olli Etuaho 3d932d83 2016-04-12T11:10:30 Defer global initializers when necessary Move global variable initializers that are not constant expressions to a function that gets called at the start of main(). This is done with an AST transformation. This needs to be done because global variable initializers must be constant in native GL, but ANGLE is more lenient with what can be put into ESSL 1.00 global initializers to remain compatible with legacy WebGL content. Non-constant global variable initializers also caused issues in HLSL output, since in HLSL output some types of expressions get unfolded into multiple statements. These include short-circuiting operators and array initialization. To make sure that these cases are covered, any initializers that can't be constant folded are deferred, even if they have the const qualifier. The old deferring mechanism in OutputHLSL is removed in favor of this new AST transformation based approach.

Olli Etuaho 1d122789 2015-11-06T15:35:17 Fix constructor constant folding The previous solution for constant folding constructors was significantly overengineered and partially incorrect. Switch to a much simpler constructor folding function that does not use an AST traverser, but simply iterates over the constant folded parameters of the constructor and doesn't do any unnecessary checks. It also reuses some code for constant folding other built-in functions. This fixes issues with initializing constant matrices with only a single parameter. Instead of copying the first component of the constructor parameter all over the matrix, passing a vec4 or matrix argument now assigns the values correctly.

Re-re-landing with fix to setting qualifiers on generated nodes. The previous version failed when a uniform was indexed, because it would set the uniform qualifier on some of the generated nodes and that interfered with the operation of UniformsHLSL. Re-landing after fixing D3D9 specific issues. HLSL doesn't support dynamic indexing of matrices and vectors, so replace that with helper functions that unroll dynamic indexing into switch/case and static indexing. Both the indexed vector/matrix expression and the index may have side effects, and these will be evaluated correctly. If necessary, index expressions that have side effects will be written to a temporary variable that will replace the index. Besides dEQP tests, this change is tested by a WebGL 2 conformance test. In the case that a dynamic index is out-of-range, the base ESSL 3.00 spec allows undefined behavior. KHR_robust_buffer_access_behavior adds the requirement that program termination should not occur and that out-of-range reads must return either a value from the active program's memory or zero, and out-of-range writes should only affect the active program's memory or do nothing. This patch clamps out-of-range indices so that either the first or last item of the matrix/vector is accessed. The code is not transformed in case the it fits within the limited subset of ESSL 1.00 given in Appendix A of the spec. If the code isn't within the restricted subset, even ESSL 1.00 shaders may require this workaround.

In practice this means that array constructors, array assignments and functions that return arrays inside complex expressions need to be replaced by symbols. After this change, ANGLE passes all dEQP-GLES3.functional.shaders.arrays tests.

Olli Etuaho a6f22096 2015-05-08T18:31:10 Make UnfoldShortCircuit to change AST instead of writing output This is needed to make way for further AST transformations to handle array expressions that need to work correctly together with unfolding short- circuiting operators. This also improves the maintainability of HLSL output by isolating the unfolding into a separate compilation step. The new version of UnfoldShortCircuit traverser will traverse the tree until an expression that needs to be unfolded is encountered. It then unfolds it and gets reset. The traverser will be run repeatedly until no more operations to unfold are found. This helps with keeping the traverser's design relatively simple. All declarations are separated to single declarations before short-circuit unfolding is run. Previously OutputHLSL already output every declaration separately.

Jamie Madill 562e81bb 2015-01-14T14:31:02 Fix Linux build, and update BUILD.gn. Re-re-land with fixes for Linux and Android. We were getting multiply defined symbol errors on Linux for some stuff in the common sources. Switch to using a static lib target for the common sources, and also sync BUILD.gn with the latest gyp.

Jamie Madill 9e0478f6 2015-01-13T11:13:54 Move the block layout code to translator. This code is easily accessible from the translator, with the proper export calls. This facilitates adding a common static library, since this code calls some methods in translator.

Olli Etuaho 5c9cd3d1 2014-12-18T13:04:25 Implement hyperbolic function support for ESSL 3.00 Emulating arc hyperbolic functions is required on HLSL, where they do not exist natively. For this, BuiltInFunctionEmulator is split into GLSL and HLSL subclasses. The GLSL subclass handles the pre-existing built-in emulation implemented for working around OSX bugs, and the HLSL subclass handles emulating asinh, acosh and atanh on HLSL.
