- Completely new implementation of SBType
- Various enhancements in several other classes
Python synthetic children providers for std::vector<T>, std::list<T> and std::map<K,V>:
- these return the actual elements into the container as the children of the container
- basic template name parsing that works (hopefully) on both Clang and GCC
- find them in examples/synthetic and in the test suite in functionalities/data-formatter/data-formatter-python-synth
New summary string token ${svar :
- the syntax is just the same as in ${var but this new token lets you read the values
coming from the synthetic children provider instead of the actual children
- Python providers above provide a synthetic child len that returns the number of elements
into the container
Full bug fix for the issue in which getting byte size for a non-complete type would crash LLDB
Several other fixes, including:
- inverted the order of arguments in the ClangASTType constructor
- EvaluationPoint now only returns SharedPointer's to Target and Process
- the help text for several type subcommands now correctly indicates argument-less options as such
