One bit flag controls one element in the gl_ClipDistance array. The writing to the disabled element in vertex shader will be ignored, and turned into zero assignment instead. - Direct3D/Mobile GL: Not implemented yet. - Added ClipDistanceTest to gl_tests and compiler unittests. - GL_APPLE_clip_distance is a subset of GL_EXT_clip_cull_distance, so GL_EXT_clip_cull_distance could be implemented in future if needed.

One could be fixed by using int cast instead of float for the clamp modifier. The other is due to array.length() couldn't return correct result for array in SSBO.

James Darpinian 27db2458 2019-10-03T13:46:28 Optimize disabling ARB_texture_rectangle In https://crrev.com/c/1838418 I added the ability to disable ARB_texture_rectangle so that we can use it in the WebGL implementation but disable it when compiling user shaders. Unfortunately disabling and re-enabling the extension causes the shader translator to be reinitialized which turns out to be more expensive than the actual work of shader translation, at least for small shaders. It's slow enough to cause timeouts in WebKit's WebGL conformance test runs. This introduces an alternate method of disabling ARB_texture_rectangle in the translator which is much faster because it avoids reinitializing the translator.

This change restores the flattening as it previously existed, however it is now only applied to VS outputs. FS inputs are no longer flattened as the previous fixes preclude the need for that workaround any longer.

Tobin Ehlis 38ff3c70 2019-05-15T10:07:09 Vulkan:Allow same-named var in nested scope ESSL 1.00 spec allows for variable with same name to override outer variable inside of a nested scope. This change adds new scope to symbol table inside of a function defintion, but after function parameters for ESSL 1.00 shaders (but not webGL). This prevents an error while parsing. This also includes some new code in translator to rename any vars that are redefined between the function body and the function parameters. This prevents an error later on when the translated shader is then parsed as a desktop GLSL version.

Shahbaz Youssefi 9d519ab1 2019-05-09T23:09:46 Vulkan: Rework layout block storage conversion Previously, a pass over the shader was made, converting shared and packed interface blocks with block storage to std140. This resulted in link success between interface blocks with different storage as they were all translated to std140. With this change, this pass is removed. The link step proceeds with the block storage specifiers as seen by GLES, and only upon Vulkan GLSL shader generation "shared" and "packed" are converted to std140.

Jiawei Shao e41df655 2018-02-09T14:31:39 ES31: Add shader version check for CS and GS This patch adds the missing check on the shader version for compute and geometry shaders, which can fix a bug that ANGLE GLSL compiler doesn't report a compile error when compiling an empty compute or geometry shader in version 100 or 300. This patch also updates the original compiler tests on the check of shader version. In these tests, the compile errors are all caused by illegal layouts instead of shader versions, which is against the purpose of the tests. This patch also fixes an incorrect case that used an empty compute shader in version 300.

Olli Etuaho e5fe7aad 2018-01-29T12:06:11 Store builtin symbols as const pointers To do this we need two types of symbol table levels: A level for built-ins and a level for user-defined symbols. User-defined symbols are non-const because function symbols created based on function prototypes are changed when the function definition is parsed. On the other hand, we want to make built-in symbols constexpr, so we should only handle them through const pointers. This also gets rid of extra empty precision stack levels. Only one level is needed to store predefined precisions.

Olli Etuaho 661fc487 2017-10-16T12:17:05 Work around NVIDIA GLSL vector-scalar op bug This adds a new AST transform VectorizeVectorScalarArithmetic. The AST transform works around incorrect handling of certain types of GLSL arithmetic operations by NVIDIA's GL driver. It works around only the most common cases where the bug reproduces, since detecting all the cases would take more sophisticated analysis of the code than what is currently easily implementable in ANGLE. When a float add operator has both vector and scalar operands, the AST transform turns the scalar operand into a vector operand. Example: vec4 f; f += 1.0; gets turned into: vec4 f; f += vec4(1.0); When a vector constructor contains a binary scalar float multiplication or division operation as its only argument, the AST transform turns both operands of the binary operation into vector operands. Example: float f, g; vec4(f * g); gets turned into: float f, g; vec4(vec4(f) * vec4(g)); Another example with compound assignment: float f, g; vec4(f *= g); gets turned into: float f, g; vec4 s0 = vec4(f); (s0 *= g, f = s0.x), s0; This latter transformation only works in case the compound assignment left hand expression doesn't have side effects.

Olli Etuaho bb5a7e29 2017-08-30T13:03:12 Allow length() on arbitrary array expressions This is required to pass some dEQP GLES 3.1 tests for arrays of arrays, and WebGL conformance tests were also recently fixed to require this behavior. The intent of the GLSL ES spec was not to restrict usage of length(). In practice GL drivers don't implement array length() on expressions with side effects correctly in all cases. HLSL doesn't have an array length operator either. Because of this we always remove array length ops from the AST before output.
