Initializing variables using for loops will be turned on by default, but it needs to be turned off in Chromium in certain cases.

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.

Also fixed wrong handling of integer RG formats in isRequiredRenderbufferFormat. Some NVIDIA GL drivers expose non-conformant multisampling modes. The conformance of multisampling modes can be queried using the extension NV_internalformat_sample_query. Use it to filter out the non-conformant modes from the modes that are exposed by ANGLE. The MAX_SAMPLES value and other similar values stored in caps also need to be lowered to match the maximum number of samples exposed for required formats. There seems to be an NVIDIA driver bug related to querying STENCIL_INDEX8 multisample format. Work around this by querying DEPTH24_STENCIL8 instead. There's also some confusion around whether RGB9_E5 should be renderable. Once the floating point texture extensions got rolled into the core GL spec, it was eventually made clear that RGB9_E5 is intended not to be renderable. The extension specs that predate float textures in the core spec do suggest that it would be renderable, but in practice drivers that advertise the extension strings don't reliably implement RGB9_E5 as renderable. Solve this by disabling it as a renderable format and adding an explanatory comment.

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.

ESSL and GLSL are not consistent on invariant matching in vertex shader and fragment shader.

This includes user-defined output variables and the built-in output variables. As only outputs need be declared with invariant, an output from one shader stage will still match an input of a subsequent stage without the input being declared as invariant. " It's not very clear if input in fragment can be declared as invariant. Mesa driver disallows use of input declared as invariant in fragment shader, while other drivers may allow it.

Olli Etuaho 218cf9ee 2016-05-20T13:55:24 Fix unpacking overlapping unpack buffer rows on NVIDIA GL When unpack parameters are set so that rows being read overlap in the unpack buffer stored in GPU memory, NVIDIA GL driver may not upload the last pixels of the last one or more rows of a texture. The driver may also crash when the amount of overlap is high. This issue affects both TexImage* and TexSubImage* calls. Work around the issue by uploading textures row by row when the rows being read overlap in the unpack buffer. The workaround could possibly be optimized by uploading several of the first rows with a single call in some cases where the amount of overlap is low, but this is expected to be a rarely used corner case, so the added complexity that the optimization would create seems like a bad tradeoff. The issue does not seem to be triggered when the layers (images) of a 3D texture overlap, as long as the rows inside the images don't. The workaround has been ported from Chromium. This patch adds setting dirty bits when unpack state is set in StateManagerGL. The included test case also reveals some issue in the D3D backend, but this is left to be addressed later.
