Refactored extractor * Output a macro for each type with the extracted info - can be used during injection in class * Simplify the header file - as can get super type and last from macro now * Store the 'origin' of a definition * Some small tidy ups to the extractor. * Improve comments on the extractor options. * Made CPPExtractor own SourceOrigins * Small fixes around SourceOrigin. * Small tidy up around macroOrign * WIP Visitor seems now to work correctly. Split out types used by ast into slang-ast-support-types.h * Fix remaining problems with C++ extractor being used with AST nodes. Add CountOf to extractor type ids. Added ReflectClassInfo::getInfo to turn an ASTNodeType into a ReflectClassInfo * Fix compiling on linux. Fix typo in memset. * Small tidy up around comments/layout. Moved NodeBase casting to NodeBase. * Make premake generate project that builds with cpp-extractor for AST. * Get the source directory from the filter in premake. * Fix typo in source path * Explicitly set the source path for premake generation for AST. * Special case handling of override to apease Clang. * Use a more general way to find the slang-ast-reflect.h file to run the extractor. * Appveyor is not triggering slang-cpp-extractor - try putting dependson together. * Put building slang-cpp-extractor first. * Disable some project options to stop MSBuild producing internal compiler errors. * Try reordering the projects in premake5.lua * Hack to try and make slang-cpp-extractor built on appveyor. * Disable flags - not required for MSBuild on appveyor. * Disable flags not required for build on AppVeyor. * Updated Visual Studio projects with slang-cpp-extractor. * Added Visual Studio slang-cpp-extractor project. 2020-02-25T16:12:16+00:00 Tim Foley tfoleyNV@users.noreply.github.com 2020-02-25T16:12:16+00:00 urn:sha1:6308a1224672944220a1fee34ae22f70212703a0 This arose when a user tried to specialize the DXR 1.1 `RayQuery` type to a local variable: ```hlsl RAY_FLAG rayFlags = RAY_FLAG_CULL_FRONT_FACING_TRIANGLES | RAY_FLAG_CULL_NON_OPAQUE; RayQuery<rayFlags> query; ``` In this case, we issued an error around `rayFlags` not being a constant as expected, but then we also crashes later on in checking because the `DeclRef` that was being used for the type had a null pointer for the generic argument corresponding to `rayFlags`. The main fix here was thus to add an `ErrorIntVal` case that can be used to represent something that should be an `IntVal` but where there was some kind of error in the input code so that the actual value isn't known to the compiler. A secondary fix here is that we were issuing error messages about expecting a constant for a parameter like `rayFlags` there *twice*, and one of those times was during the `JustChecking` part of overload resolution (when we are not supposed to emit any diagnostics). I fixed that up by allowing the `DiagnosticSink` to be used to be passed down explicitly (and allowing it to be null), while also leaving behind overloaded functions with the old signatures so that all the existing logic can continue to work unmodified. 2019-05-31T21:20:37+00:00 jsmall-nvidia jsmall@nvidia.com 2019-05-31T21:20:37+00:00 urn:sha1:6cbc3929a54d37bd23cb5efa8e3320ba02f78b2f * Prefixing source files in source/slang with slang- * Prefix source in source/slang with slang- prefix. * Rename core source files with slang- prefix. * Update project files. * Fix problems from automatic merge.
