Olli Etuaho 590f6235 2017-07-21T11:10:26 Fix getting temporary id in RewriteDoWhile There's been a long-standing bug in RewriteDoWhile where it would only call nextTemporaryId() after it had created the temporary variable. This escalated into a null pointer dereference in the recent symbol table refactoring, and initializing the traverser with the symbol table was also missing.

Olli Etuaho cccf2b00 2017-07-05T14:50:54 Reorganize AST traversal utility code Define TIntermTraverser and TIntermLValueTrackingTraverser in a separate header file. hash() function is moved out from TIntermTraverser as it is not related to the core functionality of traversing and transforming ASTs. Also reorganize some traversers to follow common conventions: - Intermediate output is now in OutputTree.h/.cpp - Max tree depth check is now in IsASTDepthBelowLimit.h/.cpp BUG=angleproject:1490 TEST=angle_unittests Change-Id: Id4968aa9d4e24d0c5bac90dc147fc9f310de0184 Reviewed-on: https://chromium-review.googlesource.com/559531 Reviewed-by: Jamie Madill <jmadill@chromium.org> Reviewed-by: Corentin Wallez <cwallez@chromium.org> Commit-Queue: Olli Etuaho <oetuaho@nvidia.com>
Olli Etuaho 4dd06d5d 2017-07-05T12:41:06 Set proper symbol ids on temporary symbol nodes Temporary symbols used to all have symbol id 0. Now they get assigned unique symbol ids. This makes it possible to keep track of them according to the symbol id instead of their name, paving way to more robust AST handling in the future.

Jamie Madill 45bcc784 2016-11-07T13:58:48 translator: Scope all classes with "sh". I was seeing an odd problem with our PoolAlloc conflicting with the glslang/Vulkan TIntermNode, so the fix was to move everything to a separate namespace. The bison grammars are also regenerated. No functional changes.

Olli Etuaho 13389b66 2016-10-16T11:48:18 Split TIntermDeclaration from TIntermAggregate The new class TIntermDeclaration is now used for struct, interface block and variable declarations. TIntermDeclaration nodes do not have a type - rather the type is stored in each child node. The types may differ in case the declaration is a series of array declarators with mismatching sizes. TIntermAggregate is still used for function calls, function prototypes, function parameter lists and invariant declarations.

Olli Etuaho 6d40bbdd 2016-09-30T13:49:38 Split TIntermBlock from TIntermAggregate The new TIntermBlock node class replaces TIntermAggregate nodes with the EOpSequence op. It represents the root node of the tree which is a list of declarations and function definitions, and any code blocks that can be denoted by curly braces. These include function and loop bodies, and if-else branches. This change enables a bunch of more compile-time type checking, and makes the AST code easier to understand and less error-prone. The PostProcess step that used to be done to ensure that the root node is TIntermAggregate is removed in favor of making sure that the root node is a TIntermBlock in the glslang.y parsing code. Intermediate output formatting is improved to print the EOpNull error in a clearer way. After this patch, TIntermAggregate is still used for function definitions, function prototypes, function parameter lists, function calls, variable and invariant declarations and the comma (sequence) operator.
