I will think > more about this approach and get back to you. I spent some time thinking about this. ClandExpressionDeclMap doesn't really explicitly lookup method names. If we have an expression like "v.size()", we lookup what "v" is, and that conveys to Clang about the existence of a method "size" in its class. The requirement for alternate names kicks in (so to say) when we are looking for the address of the method. I am not very clear on how we can cleanly keep track of all the methods parsed, while looking up variables, in ClangExpressionDeclMap and use that knowledge while looking up addresses. Do you have any suggestions?
I agree that it is indeed odd to have a method GetMangledNamesForFunction in SymbolFile which is useful only for expression evaluation. How about having a temp object that ClangExpressionDeclMap registers with SymbolFile, and cleans it up after expression evaluation is done? SymbolFile stuffs in to the object all info that ClangExpressionDeclMap could potentially use while parsing the DIEs. ExpressionEvaluationIndex? http://reviews.llvm.org/D12809 _______________________________________________ lldb-commits mailing list lldb-commits@lists.llvm.org http://lists.llvm.org/cgi-bin/mailman/listinfo/lldb-commits
