Stuart Morgan 9d737966 2019-08-14T12:25:12 Standardize copyright notices to project style For all "ANGLE Project" copyrights, standardize to the format specified by the style guide. Changes: - "Copyright (c)" and "Copyright(c)" changed to just "Copyright". - Removed the second half of date ranges ("Y1Y1-Y2Y2"->"Y1Y1"). - Fixed a small number of files that had no copyright date using the initial commit year from the version control history. - Fixed one instance of copyright being "The ANGLE Project" rather than "The ANGLE Project Authors" These changes are applied both to the copyright of source file, and where applicable to copyright statements that are generated by templates.

Olli Etuaho ea22b7a5 2018-01-04T17:09:11 Constant fold array indexing and comparison A virtual function to get the constant value of an AST node is added to TIntermTyped. This way a constant value can be retrieved conveniently from multiple different types of nodes. TIntermSymbol nodes pointing to a const variable can return the value associated with the variable, constructor nodes can build a constant value from their arguments, and indexing nodes can index into a constant array. This enables constant folding operations on constant arrays, while making sure that large amounts of data are not duplicated in the output shader. When folding an operation makes sense, the values of the arguments can be retrieved by using the new TIntermTyped::getConstantValue(). When folding an operation would result in duplicating data, the AST can just be left to be written out as is. For example, if the code contains a constant array of arrays, indexing into individual elements of the inner arrays can be folded, but indexing the top level array is left in place and not replaced with duplicated array literals. Constant folding is supported for indexing and comparisons of arrays. In case constant arrays are only referenced through foldable operations, the variable declarations will be pruned from the AST by the RemoveUnreferencedVariables step.

This includes constant folding support for functions that may be constant folded, and support for both GLSL and HLSL output. In HLSL several of the functions need to be emulated. The precision qualification for the return value of some of these functions is determined by special rules, that are now part of type promotion for TIntermUnary nodes and determining the type of TIntermAggregate nodes.

Compilation flags change for some of the tests, but this should only have a minor effect on code coverage - mostly affecting non-core parts such as intermediate output.

Olli Etuaho 2d73665d 2016-11-30T10:37:49 Handle constant folding arithmetic involving infinity Constant folding arithmetic operations that involve infinity are now handled correctly in the cases where the result is infinity or zero. The implementation mostly relies on C++ to implement IEEE float arithmetic correctly so that unnecessary overhead is avoided. Constant folding arithmetic operations that result in overflow now issue a warning but result in infinity. This is not mandated by the spec but is a reasonable choice since it is the behavior of the default IEEE rounding mode. Constant folding arithmetic operations that result in NaN in IEEE will generate a warning but the NaN is kept. This is also not mandated by the spec, but is among the allowed behaviors. There's no special handling for ESSL 1.00. ESSL 1.00 doesn't really have the concept of NaN, but since it is not feasible to control generating NaNs at shader run time either way, it should not be a big issue if constant folding may generate them as well.
