Fixed GetModuleSpecifications() to work better overall: - MachO files now correctly extract the UUID all the time - More file size and offset verification done for universal mach-o files to watch for truncated files - ObjectContainerBSDArchive now supports enumerating all objects in BSD archives (.a files) - lldb_private::Module() can not be properly constructed using a ModuleSpec for a .o file in a .a file - The BSD archive plug-in shares its cache for GetModuleSpecifications() and the create callback - Improved printing for ModuleSpec objects git-svn-id: https://llvm.org/svn/llvm-project/lldb/trunk@186211 91177308-0d34-0410-b5e6-96231b3b80d8

<rdar://problem/13854277> <rdar://problem/13594769> Main changes in this patch include: - cleanup plug-in interface and use ConstStrings for plug-in names - Modfiied the BSD Archive plug-in to be able to pick out the correct .o file when .a files contain multiple .o files with the same name by using the timestamp - Modified SymbolFileDWARFDebugMap to properly verify the timestamp on .o files it loads to ensure we don't load updated .o files and cause problems when debugging The plug-in interface changes: Modified the lldb_private::PluginInterface class that all plug-ins inherit from: Changed: virtual const char * GetPluginName() = 0; To: virtual ConstString GetPluginName() = 0; Removed: virtual const char * GetShortPluginName() = 0; - Fixed up all plug-in to adhere to the new interface and to return lldb_private::ConstString values for the plug-in names. - Fixed all plug-ins to return simple names with no prefixes. Some plug-ins had prefixes and most ones didn't, so now they all don't have prefixed names, just simple names like "linux", "gdb-remote", etc. git-svn-id: https://llvm.org/svn/llvm-project/lldb/trunk@181631 91177308-0d34-0410-b5e6-96231b3b80d8

Added the ability to extract a ModuleSpecList (a new class) from an ObjectFile. This is designed to be used when you have an object file that contains one or more architectures (MacOSX universal (fat) files) and/or one or more objects (BSD archive (.a files)). There is a new static ObjectFile function you can call: size_t ObjectFile::GetModuleSpecifications (const FileSpec &file, lldb::offset_t file_offset, ModuleSpecList &specs) This will fill in "specs" which the details of all the module specs (file + arch + UUID (if there is one) + object name (for BSD archive objects eventually) + file offset to the object in question). This helps us when a user specifies a file that contains a single architecture, and also helps us when we are given a debug symbol file (like a dSYM file on MacOSX) that contains one or more architectures and we need to be able to match it up to an existing Module that has no debug info. git-svn-id: https://llvm.org/svn/llvm-project/lldb/trunk@180224 91177308-0d34-0410-b5e6-96231b3b80d8

After discussing with Chris Lattner, we require C++11, so lets get rid of the macros and just use C++11. git-svn-id: https://llvm.org/svn/llvm-project/lldb/trunk@179805 91177308-0d34-0410-b5e6-96231b3b80d8

Since we use C++11, we should switch over to using std::unique_ptr when C++11 is being used. To do this, we follow what we have done for shared pointers and we define a STD_UNIQUE_PTR macro that can be used and it will "do the right thing". Due to some API differences in std::unique_ptr and due to the fact that we need to be able to compile without C++11, we can't use move semantics so some code needed to change so that it can compile with either C++. Anyone wanting to use a unique_ptr or auto_ptr should now use the "STD_UNIQUE_PTR(TYPE)" macro. git-svn-id: https://llvm.org/svn/llvm-project/lldb/trunk@179779 91177308-0d34-0410-b5e6-96231b3b80d8

<rdar://problem/13159777> lldb was mmap'ing archive files once per .o file it loads, now it correctly shares the archive between modules. LLDB was also always mapping entire contents of universal mach-o files, now it maps just the slice that is required. Added a new logging channel for "lldb" called "mmap" to help track future regressions. Modified the ObjectFile and ObjectContainer plugin interfaces to take a data offset along with the file offset and size so we can implement the correct caching and efficient reading of parts of files without mmap'ing the entire file like we used to. The current implementation still keeps entire .a files mmaped (once) and entire slices from universal files mmaped to ensure that if a client builds their binaries during a debug session we don't lose our data and get corrupt object file info and debug info. git-svn-id: https://llvm.org/svn/llvm-project/lldb/trunk@174524 91177308-0d34-0410-b5e6-96231b3b80d8

<rdar://problem/13069948> Major fixed to allow reading files that are over 4GB. The main problems were that the DataExtractor was using 32 bit offsets as a data cursor, and since we mmap all of our object files we could run into cases where if we had a very large core file that was over 4GB, we were running into the 4GB boundary. So I defined a new "lldb::offset_t" which should be used for all file offsets. After making this change, I enabled warnings for data loss and for enexpected implicit conversions temporarily and found a ton of things that I fixed. Any functions that take an index internally, should use "size_t" for any indexes and also should return "size_t" for any sizes of collections. git-svn-id: https://llvm.org/svn/llvm-project/lldb/trunk@173463 91177308-0d34-0410-b5e6-96231b3b80d8

Add new ArchSpec methods, IsCompatibleMatch() and IsExactMatch(). The operator== method is a synonym for IsExactMatch(). The essential difference between these two is that IsCompatibleMatch() will say that armv7 and armv7s are compatible and return true. IsExactMatch() will say that armv7 and armv7s are not a match. An armv7s cpu can run either generic armv7 binaries or armv7s binaries (the latter being tuned for it). When we're picking the slice of a universal Mach-O file to load in an armv7s Target, we need to be able to first look for an exact cpu subtype match (armv7s == armv7s) and failing that, looking for a slice with a compatible architecture. Update ObjectContainerUniversalMachO::GetObjectFile to prefer an exact match of the cpu type, falling back to a compatible match if necessary. <rdar://problem/12593515> git-svn-id: https://llvm.org/svn/llvm-project/lldb/trunk@167365 91177308-0d34-0410-b5e6-96231b3b80d8

<rdar://problem/10103468> I started work on being able to add symbol files after a debug session had started with a new "target symfile add" command and quickly ran into problems with stale Address objects in breakpoint locations that had lldb_private::Section pointers into modules that had been removed or replaced. This also let to grabbing stale modules from those sections. So I needed to thread harded the Address, Section and related objects. To do this I modified the ModuleChild class to now require a ModuleSP on initialization so that a weak reference can created. I also changed all places that were handing out "Section *" to have them hand out SectionSP. All ObjectFile, SymbolFile and SymbolVendors were inheriting from ModuleChild so all of the find plug-in, static creation function and constructors now require ModuleSP references instead of Module *. Address objects now have weak references to their sections which can safely go stale when a module gets destructed. This checkin doesn't complete the "target symfile add" command, but it does get us a lot clioser to being able to do such things without a high risk of crashing or memory corruption. git-svn-id: https://llvm.org/svn/llvm-project/lldb/trunk@151336 91177308-0d34-0410-b5e6-96231b3b80d8

Big change in the way ObjectFile file contents are managed. We now mmap() the entire object file contents into memory with MAP_PRIVATE. We do this because object file contents can change on us and currently this helps alleviate this situation. It also make the code for accessing object file data much easier to manage and we don't end up opening the file, reading some data and closing the file over and over. git-svn-id: https://llvm.org/svn/llvm-project/lldb/trunk@148017 91177308-0d34-0410-b5e6-96231b3b80d8

Don't put modules for .o files into the global shared module list. We used to do this because we needed to find the shared pointer for a .o file when the .o file's module was needed in a SymbolContext since the module in a symbol context was a shared pointer. Now that we are using intrusive pointers we don't have this limitation anymore since any instrusive shared pointer can be made from a pointer to an object all on its own. Also switched over to having the Module and SymbolVendor use shared pointers to their object files as had a leak on MacOSX when the SymbolVendor's object file wasn't the same as the Module's (debug info in a stand along file (dSYM file)). Now everything will correctly clean itself up when the module goes away after an executable gets rebuilt. Now we correctly get rid of .o files that are used with the DWARF with debug map executables on subsequent runs since the only shared pointer to the object files in from the DWARF symbol file debug map parser, and when the module gets replaced, it destroys to old one along with all .o files. Also added a small optimization when using BSD archives where we will remove old BSD containers from the shared list when they are outdated. git-svn-id: https://llvm.org/svn/llvm-project/llvdb/trunk@140002 91177308-0d34-0410-b5e6-96231b3b80d8

Modified the ArchSpec to take an optional "Platform *" when setting the triple. This allows you to have a platform selected, then specify a triple using "i386" and have the remaining triple items (vendor, os, and environment) set automatically. Many interpreter commands take the "--arch" option to specify an architecture triple, so now the command options needed to be able to get to the current platform, so the Options class now take a reference to the interpreter on construction. Modified the build LLVM building in the Xcode project to use the new Xcode project level user definitions: LLVM_BUILD_DIR - a path to the llvm build directory LLVM_SOURCE_DIR - a path to the llvm sources for the llvm that will be used to build lldb LLVM_CONFIGURATION - the configuration that lldb is built for (Release, Release+Asserts, Debug, Debug+Asserts). I also changed the LLVM build to not check if "lldb/llvm" is a symlink and then assume it is a real llvm build directory versus the unzipped llvm.zip package, so now you can actually have a "lldb/llvm" directory in your lldb sources. git-svn-id: https://llvm.org/svn/llvm-project/llvdb/trunk@129112 91177308-0d34-0410-b5e6-96231b3b80d8

LLDB now has "Platform" plug-ins. Platform plug-ins are plug-ins that provide an interface to a local or remote debugging platform. By default each host OS that supports LLDB should be registering a "default" platform that will be used unless a new platform is selected. Platforms are responsible for things such as: - getting process information by name or by processs ID - finding platform files. This is useful for remote debugging where there is an SDK with files that might already or need to be cached for debug access. - getting a list of platform supported architectures in the exact order they should be selected. This helps the native x86 platform on MacOSX select the correct x86_64/i386 slice from universal binaries. - Connect to remote platforms for remote debugging - Resolving an executable including finding an executable inside platform specific bundles (macosx uses .app bundles that contain files) and also selecting the appropriate slice of universal files for a given platform. So by default there is always a local platform, but remote platforms can be connected to. I will soon be adding a new "platform" command that will support the following commands: (lldb) platform connect --name machine1 macosx connect://host:port Connected to "machine1" platform. (lldb) platform disconnect macosx This allows LLDB to be well setup to do remote debugging and also once connected process listing and finding for things like: (lldb) process attach --name x<TAB> The currently selected platform plug-in can now auto complete any available processes that start with "x". The responsibilities for the platform plug-in will soon grow and expand. git-svn-id: https://llvm.org/svn/llvm-project/llvdb/trunk@127286 91177308-0d34-0410-b5e6-96231b3b80d8

Abtracted all mach-o and ELF out of ArchSpec. This patch is a modified form of Stephen Wilson's idea (thanks for the input Stephen!). What I ended up doing was: - Got rid of ArchSpec::CPU (which was a generic CPU enumeration that mimics the contents of llvm::Triple::ArchType). We now rely upon the llvm::Triple to give us the machine type from llvm::Triple::ArchType. - There is a new ArchSpec::Core definition which further qualifies the CPU core we are dealing with into a single enumeration. If you need support for a new Core and want to debug it in LLDB, it must be added to this list. In the future we can allow for dynamic core registration, but for now it is hard coded. - The ArchSpec can now be initialized with a llvm::Triple or with a C string that represents the triple (it can just be an arch still like "i386"). - The ArchSpec can still initialize itself with a architecture type -- mach-o with cpu type and subtype, or ELF with e_machine + e_flags -- and this will then get translated into the internal llvm::Triple::ArchSpec + ArchSpec::Core. The mach-o cpu type and subtype can be accessed using the getter functions: uint32_t ArchSpec::GetMachOCPUType () const; uint32_t ArchSpec::GetMachOCPUSubType () const; But these functions are just converting out internal llvm::Triple::ArchSpec + ArchSpec::Core back into mach-o. Same goes for ELF. All code has been updated to deal with the changes. This should abstract us until later when the llvm::TargetSpec stuff gets finalized and we can then adopt it. git-svn-id: https://llvm.org/svn/llvm-project/llvdb/trunk@126278 91177308-0d34-0410-b5e6-96231b3b80d8

Added support for attaching to a remote debug server with the new command: (lldb) process connect <remote-url> Currently when you specify a file with the file command it helps us to find a process plug-in that is suitable for debugging. If you specify a file you can rely upon this to find the correct debugger plug-in: % lldb a.out Current executable set to 'a.out' (x86_64). (lldb) process connect connect://localhost:2345 ... If you don't specify a file, you will need to specify the plug-in name that you wish to use: % lldb (lldb) process connect --plugin process.gdb-remote connect://localhost:2345 Other connection URL examples: (lldb) process connect connect://localhost:2345 (lldb) process connect tcp://127.0.0.1 (lldb) process connect file:///dev/ttyS1 We are currently treating the "connect://host:port" as a way to do raw socket connections. If there is a URL for this already, please let me know and we will adopt it. So now you can connect to a remote debug server with the ProcessGDBRemote plug-in. After connection, it will ask for the pid info using the "qC" packet and if it responds with a valid process ID, it will be equivalent to attaching. If it response with an error or invalid process ID, the LLDB process will be in a new state: eStateConnected. This allows us to then download a program or specify the program to run (using the 'A' packet), or specify a process to attach to (using the "vAttach" packets), or query info about the processes that might be available. git-svn-id: https://llvm.org/svn/llvm-project/llvdb/trunk@124846 91177308-0d34-0410-b5e6-96231b3b80d8
