<rdar://problem/11757916> Make breakpoint setting by file and line much more efficient by only looking for inlined breakpoint locations if we are setting a breakpoint in anything but a source implementation file. Implementing this complex for a many reasons. Turns out that parsing compile units lazily had some issues with respect to how we need to do things with DWARF in .o files. So the fixes in the checkin for this makes these changes: - Add a new setting called "target.inline-breakpoint-strategy" which can be set to "never", "always", or "headers". "never" will never try and set any inlined breakpoints (fastest). "always" always looks for inlined breakpoint locations (slowest, but most accurate). "headers", which is the default setting, will only look for inlined breakpoint locations if the breakpoint is set in what are consudered to be header files, which is realy defined as "not in an implementation source file". - modify the breakpoint setting by file and line to check the current "target.inline-breakpoint-strategy" setting and act accordingly - Modify compile units to be able to get their language and other info lazily. This allows us to create compile units from the debug map and not have to fill all of the details in, and then lazily discover this information as we go on debuggging. This is needed to avoid parsing all .o files when setting breakpoints in implementation only files (no inlines). Otherwise we would need to parse the .o file, the object file (mach-o in our case) and the symbol file (DWARF in the object file) just to see what the compile unit was. - modify the "SymbolFileDWARFDebugMap" to subclass lldb_private::Module so that the virtual "GetObjectFile()" and "GetSymbolVendor()" functions can be intercepted when the .o file contenst are later lazilly needed. Prior to this fix, when we first instantiated the "SymbolFileDWARFDebugMap" class, we would also make modules, object files and symbol files for every .o file in the debug map because we needed to fix up the sections in the .o files with information that is in the executable debug map. Now we lazily do this in the DebugMapModule::GetObjectFile() Cleaned up header includes a bit as well. llvm-svn: 162860

SBFrame is now threadsafe using some extra tricks. One issue is that stack frames might go away (the object itself, not the actual logical frame) when we are single stepping due to the way we currently sometimes end up flushing frames when stepping in/out/over. They later will come back to life represented by another object yet they have the same StackID. Now when you get a lldb::SBFrame object, it will track the frame it is initialized with until the thread goes away or the StackID no longer exists in the stack for the thread it was created on. It uses a weak_ptr to both the frame and thread and also stores the StackID. These three items allow us to determine when the stack frame object has gone away (the weak_ptr will be NULL) and allows us to find the correct frame again. In our test suite we had such cases where we were just getting lucky when something like this happened: 1 - stop at breakpoint 2 - get first frame in thread where we stopped 3 - run an expression that causes the program to JIT and run code 4 - run more expressions on the frame from step 2 which was very very luckily still around inside a shared pointer, yet, not part of the current thread (a new stack frame object had appeared with the same stack ID and depth). We now avoid all such issues and properly keep up to date, or we start returning errors when the frame doesn't exist and always responds with invalid answers. Also fixed the UserSettingsController (not going to rewrite this just yet) so that it doesn't crash on shutdown. Using weak_ptr's came in real handy to track when the master controller has already gone away and this allowed me to pull out the previous NotifyOwnerIsShuttingDown() patch as it is no longer needed. llvm-svn: 149231

While tracking down memory consumption issue a few things were needed: the ability to dump more information about modules in "target modules list". We can now dump the shared pointer reference count for modules, the pointer to the module itself (in case performance tools can help track down who has references to said pointer), and the modification time. Added "target delete [target-idx ...]" to be able to delete targets when they are no longer needed. This will help track down memory usage issues and help to resolve when module ref counts keep getting incremented. If the command gets no arguments, the currently selected target will be deleted. If any arguments are given, they must all be valid target indexes (use the "target list" command to get the current target indexes). Took care of a bunch of "no newline at end of file" warnings. TimeValue objects can now dump their time to a lldb_private::Stream object. Modified the "target modules list --global" command to not error out if there are no targets since it doesn't require a target. Fixed an issue in the MacOSX DYLD dynamic loader plug-in where if a shared library was updated on disk, we would keep using the older one, even if it was updated. Don't allow the ModuleList::GetSharedModule(...) to return an empty module. Previously we could specify a valid path on disc to a module, and specify an architecture that wasn't contained in that module and get a shared pointer to a module that wouldn't be able to return an object file or a symbol file. We now make sure an object file can be extracted prior to adding the shared pointer to the module to get added to the shared list. llvm-svn: 137196
