Modified all logging calls to hand out shared pointers to make sure we don't crash if we disable logging when some code already has a copy of the logger. Prior to this fix, logs were handed out as pointers and if they were held onto while a log got disabled, then it could cause a crash. Now all logs are handed out as shared pointers so this problem shouldn't happen anymore. We are also using our new shared pointers that put the shared pointer count and the object into the same allocation for a tad better performance. llvm-svn: 118319

Changed the SymbolFile::FindFunction() function calls to only return lldb_private::Function objects. Previously the SymbolFileSymtab subclass would return lldb_private::Symbol objects when it was asked to find functions. The Module::FindFunctions (...) now take a boolean "bool include_symbols" so that the module can track down functions and symbols, yet functions are found by the SymbolFile plug-ins (through the SymbolVendor class), and symbols are gotten through the ObjectFile plug-ins. Fixed and issue where the DWARF parser might run into incomplete class member function defintions which would make clang mad when we tried to make certain member functions with invalid number of parameters (such as an operator= operator that had no parameters). Now we just avoid and don't complete these incomplete functions. llvm-svn: 124359

Added function name types to allow us to set breakpoints by name more intelligently. The four name types we currently have are: eFunctionNameTypeFull = (1 << 1), // The function name. // For C this is the same as just the name of the function // For C++ this is the demangled version of the mangled name. // For ObjC this is the full function signature with the + or // - and the square brackets and the class and selector eFunctionNameTypeBase = (1 << 2), // The function name only, no namespaces or arguments and no class // methods or selectors will be searched. eFunctionNameTypeMethod = (1 << 3), // Find function by method name (C++) with no namespace or arguments eFunctionNameTypeSelector = (1 << 4) // Find function by selector name (ObjC) names this allows much more flexibility when setting breakoints: (lldb) breakpoint set --name main --basename (lldb) breakpoint set --name main --fullname (lldb) breakpoint set --name main --method (lldb) breakpoint set --name main --selector The default: (lldb) breakpoint set --name main will inspect the name "main" and look for any parens, or if the name starts with "-[" or "+[" and if any are found then a full name search will happen. Else a basename search will be the default. Fixed some command option structures so not all options are required when they shouldn't be. Cleaned up the breakpoint output summary. Made the "image lookup --address <addr>" output much more verbose so it shows all the important symbol context results.
