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. Added a GetDescription method to many of the SymbolContext objects for the more verbose output. llvm-svn: 107075

Remove the eSymbolTypeFunction, eSymbolTypeGlobal, and eSymbolTypeStatic. They will now be represented as: eSymbolTypeFunction: eSymbolTypeCode with IsDebug() == true eSymbolTypeGlobal: eSymbolTypeData with IsDebug() == true and IsExternal() == true eSymbolTypeStatic: eSymbolTypeData with IsDebug() == true and IsExternal() == false This simplifies the logic when dealing with symbols and allows for symbols to be coalesced into a single symbol most of the time. Enabled the minimal symbol table for mach-o again after working out all the kinks. We now get nice concise symbol tables and debugging with DWARF in the .o files with a debug map in the binary works well again. There were issues where the SymbolFileDWARFDebugMap symbol file parser was using symbol IDs and symbol indexes interchangeably. Now that all those issues are resolved debugging is working nicely. llvm-svn: 113678
