- Changed namespace chain (org::antlr::v4::runtime) to just antlr4 in all files.
- Fixed runtime tests for that.
- Added conversion of the xpath code, which compiles now (no tests, tho, as there are runtime tests for it).
- Removed TestRig stuff. That doesn't work in C++.
- Avoiding double semicolons is tricky with the kind of rule nesting. Previous changes for that caused the tests to break as there were semicolons missing then.
- VS complained about the shift code generated using 1L as base, which is signed. Changed that to 1ULL, which is what is actually intended.
- Reverted the change to avoid a warning in RuleSempredFunction() in Cpp.stg as the fix didn't work 100%. We need a different solution.
- A few remaining changes had to be done for the C++ runtime tests which now completely pass.
- Added a runtime testing overview document.
- Added a description of C++ target.
- Updated the ANTLR release document.
- Fixed all disabled tests and enabled them.
- Some more adjustments of the test template + target template was needed.
- Worked on semicolon usage in Cpp.stg to avoid double semicolons. Might need more work, tho.
- Allow loading new input instead of setting up a new input stream.
- Made is<> template function inline, for hopefully faster execution.
- A few other fixes in stream + lexer classes.
- Reverted another rename from context to _localctx in the Cpp.stg file as this is used for certain actions.
- The ATN simular generated lots of duplicate DFAStates that consumed a lot of memory, due to missing hashing/== functionality. By using an own hasher/comparer for the unordered_map in the DFA this problem could be solved. Memory consumption is now 100% stable on a low level (e.g. 115MB for a fairly complex parser) and doesn't increase anymore after the warmup phase.
- Fixed also a number of things reported by the clang static analyzer.
- Fixed a bug in Parser.cpp where the stop token in the current context would be set twice overriding a previously set value.
- Optimized token range check via ATN::nextTokens, by not duplicating the stored interval set for a given state.
- Slightly improved IntervalSet::contains() by moving some tests out of the loop and not using intermediate variables.
- Reverted the change from RecognitionException to exception_ptr (and removed the make_exception_ptr() call). This is not needed and only leads to object slicing. Instead we check directly the given exception object for the individual handling in reportError() and use std::current_exception() to get the exception pointer for our contexts.
- Removed precompiled header stuff from cmake file for the same reasons as I did in the XCode project (Visual Studio still pending).
In order to ease including the antlr runtime in other projects the include structure has been changed:
- Removed precompiled header usage (only OSX, VS + cmake still need updates).
- Created umbrella header antlr4-runtime.h that contains everything needed in a target application.
- Changed all includes to use relative paths, so it is enough to add the src folder to the header search path in an application.
- Also fixed a smaller issue in the C++ template wrt the serialized ATN storage for large grammars.
