Olli Etuaho e80825ef 2018-02-16T10:24:53 Simplify built-in function node initialization Built-ins with no math op associated with them now have the op code EOpCallBuiltInFunction set. This makes initializing built-in function nodes simpler, since they can always get the op code from the function symbol. We also no longer look for functions in inner scopes, only from the global scope and from built-in functions.

Olli Etuaho fbb1c792 2018-01-19T16:26:59 Store symbol names as a ImmutableString This will enable compile-time initialization of built-in symbols as well as reducing copying strings. Most of the code that deals with names is changed to use ImmutableString where it makes sense to avoid conversions. The lexer/parser now allocate const char pointers into pool memory instead of allocating TStrings. These are then converted to ImmutableString upon entering TParseContext.

Olli Etuaho 68981eb5 2018-01-23T17:46:12 Track parameter qualifiers of functions in call nodes We now add a reference to TFunction to all TIntermAggregate nodes where it is possible, including built-in ops. We also make sure that internal TFunctions added in traversers have correct parameter qualifiers. This makes TLValueTrackingTraverser much simpler. Instead of storing traversed functions or looking up builtin functions from the symbol table, determining which function parameters are out parameters can now be done simply by looking it up from the function symbol associated with the aggregate node. Symbol instances are no longer deleted when a symbol table level goes out of scope, and TFunction destructor no longer clears the parameters. They're all either statically allocated or pool allocated, so this does not result in leaks.

Olli Etuaho 195be942 2017-12-04T23:40:14 Always create TVariables for TIntermSymbol nodes TIntermSymbol nodes are now constructed based on a specific TVariable. This makes sure that all TIntermSymbol nodes that are created to refer to a specific temporary in an AST transform will have consistent data. The TVariable objects are not necessarily added to the symbol table levels - just those variables that can be referred to by their name during parsing need to be reachable through there. In the future this can be taken a step further so that TIntermSymbol nodes just to point to a TVariable instead of duplicating the information.

Olli Etuaho bd3cd506 2017-11-03T15:48:52 Clean up HLSL constructor output Split generating HLSL struct constructors from generating built-in type constructors, as these didn't have much in common. Struct constructors are now only generated when they are needed, as opposed to before, when they were generated on any use of a struct. This changes built-in constructor naming to include "_ctor" and gets rid of having special built-in type names just for constructors. This will make it easier to do changes to constructor output, for example to add constructors for structs in std140 layout. This might be needed to implement SSBOs efficiently. This includes one bug fix for writing out struct declarations for varyings. Also improves const-correctness of accessing structs through TType in general.

Olli Etuaho 2d88e9bc 2017-07-21T16:52:03 Guarantee that symbol nodes get unique ids The code is refactored so that symbol nodes can only be initialized with an unique id object. This prevents accidentally forgetting to create an id for a symbol node. This opens up possibilities for future optimization: For example the names and types of symbols could be stored in a central location inside the SymbolTable, and TIntermSymbol nodes would only need to store the symbol id. The symbol id could be used to look up the name and type of the node.

It is a bit of a special case: it only exists in desktop GLSL and not ESSL, and it shouldn't be exposed to the parser. We add a new level to the symbol table that's hidden from the parser to make adding this kind of builtins in AST transforms consistent with the way ESSL builtins are supported.

Olli Etuaho ab918821 2017-07-14T17:03:42 Clamp point size to maximum point size from the API on NVIDIA NVIDIA OpenGL drivers have a bug where the point size range is being reported incorrectly - it appears the core GL driver incorrectly gives the range for smooth points, when it should be giving the range for aliased points. Clamp the actual point size to the maximum point size reported from the API so that the GLES spec is followed. The same workaround seems to be necessary also on Android. The issue was revealed by the trybots, and has not been fully diagnosed though. The newly added test fails on AMD OpenGL. As a part of this change, the existing tests in PointSpritesTest are refactored to use gl_raii.
