Added support for inlined stack frames being represented as real stack frames which is now on by default. Frames are gotten from the unwinder as concrete frames, then if inline frames are to be shown, extra information to track and reconstruct these frames is cached with each Thread and exanded as needed. I added an inline height as part of the lldb_private::StackID class, the class that helps us uniquely identify stack frames. This allows for two frames to shared the same call frame address, yet differ only in inline height. Fixed setting breakpoint by address to not require addresses to resolve. A quick example: % cat main.cpp % ./build/Debug/lldb test/stl/a.out Current executable set to 'test/stl/a.out' (x86_64). (lldb) breakpoint set --address 0x0000000100000d31 Breakpoint created: 1: address = 0x0000000100000d31, locations = 1 (lldb) r Launching 'a.out' (x86_64) (lldb) Process 38031 Stopped * thread #1: tid = 0x2e03, pc = 0x0000000100000d31, where = a.out`main [inlined] std::string::_M_data() const at /usr/include/c++/4.2.1/bits/basic_string.h:280, stop reason = breakpoint 1.1, queue = com.apple.main-thread 277 278 _CharT* 279 _M_data() const 280 -> { return _M_dataplus._M_p; } 281 282 _CharT* 283 _M_data(_CharT* __p) (lldb) bt thread #1: tid = 0x2e03, stop reason = breakpoint 1.1, queue = com.apple.main-thread frame #0: pc = 0x0000000100000d31, where = a.out`main [inlined] std::string::_M_data() const at /usr/include/c++/4.2.1/bits/basic_string.h:280 frame #1: pc = 0x0000000100000d31, where = a.out`main [inlined] std::string::_M_rep() const at /usr/include/c++/4.2.1/bits/basic_string.h:288 frame #2: pc = 0x0000000100000d31, where = a.out`main [inlined] std::string::size() const at /usr/include/c++/4.2.1/bits/basic_string.h:606 frame #3: pc = 0x0000000100000d31, where = a.out`main [inlined] operator<< <char, std::char_traits<char>, std::allocator<char> > at /usr/include/c++/4.2.1/bits/basic_string.h:2414 frame #4: pc = 0x0000000100000d31, where = a.out`main + 33 at /Volumes/work/gclayton/Documents/src/lldb/test/stl/main.cpp:14 frame #5: pc = 0x0000000100000d08, where = a.out`start + 52 Each inline frame contains only the variables that they contain and each inlined stack frame is treated as a single entity. llvm-svn: 111877

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
