Makefile	[LLDB][ClangExpression] Allow expression evaluation from within C++ Lambdas This patch adds support for evaluating expressions which reference a captured this from within the context of a C++ lambda expression. Currently LLDB doesn't provide Clang with enough information to determine that we're inside a lambda expression and are allowed to access variables on a captured this; instead Clang simply fails to parse the expression. There are two problems to solve here: 1. Make sure clang::Sema doesn't reject the expression due to an illegal member access. 2. Materialize all the captured variables/member variables required to evaluate the expression. To address (1), we currently import the outer structure's AST context onto $__lldb_class, making the contextClass and the NamingClass match, a requirement by clang::Sema::BuildPossibleImplicitMemberExpr. To address (2), we inject all captured variables as locals into the expression source code. **Testing** * Added API test	3 年前
