* <rdar://problem/13069948>Greg Clayton2013-01-251-1/+1
| | | | | | | | | | | | 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. llvm-svn: 173463

* The second part in thread hardening the internals of LLDB where we makeGreg Clayton2012-02-181-29/+17
| | | | | | | | | | | | | | | | the lldb_private::StackFrame objects hold onto a weak pointer to the thread object. The lldb_private::StackFrame objects the the most volatile objects we have as when we are doing single stepping, frames can often get lost or thrown away, only to be re-created as another object that still refers to the same frame. We have another bug tracking that. But we need to be able to have frames no longer be able to get the thread when they are not part of a thread anymore, and this is the first step (this fix makes that possible but doesn't implement it yet). Also changed lldb_private::ExecutionContextScope to return shared pointers to all objects in the execution context to further thread harden the internals. llvm-svn: 150871
* Created a std::string in the base StopInfo class for the description andGreg Clayton2011-06-041-0/+4

* Added generic register numbers for simple ABI argument registers and definedGreg Clayton2011-05-151-1/+1
| | | | | | | | | | | | | | | | | the appropriate registers for arm and x86_64. The register names for the arguments that are the size of a pointer or less are all named "arg1", "arg2", etc. This allows you to read these registers by name: (lldb) register read arg1 arg2 arg3 ... You can also now specify you want to see alternate register names when executing the read register command: (lldb) register read --alternate (lldb) register read -A llvm-svn: 131376
* Moved all code from ArchDefaultUnwindPlan and ArchVolatileRegs into theirGreg Clayton2011-05-111-67/+67
| | | | | | | | | | | | | | | respective ABI plugins as they were plug-ins that supplied ABI specfic info. Also hookep up the UnwindAssemblyInstEmulation so that it can generate the unwind plans for ARM. Changed the way ABI plug-ins are handed out when you get an instance from the plug-in manager. They used to return pointers that would be mananged individually by each client that requested them, but now they are handed out as shared pointers since there is no state in the ABI objects, they can be shared. llvm-svn: 131193
* While implementing unwind information using UnwindAssemblyInstEmulation I ranGreg Clayton2011-05-091-61/+131
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | into some cleanup I have been wanting to do when reading/writing registers. Previously all RegisterContext subclasses would need to implement: virtual bool ReadRegisterBytes (uint32_t reg, DataExtractor &data); virtual bool WriteRegisterBytes (uint32_t reg, DataExtractor &data, uint32_t data_offset = 0); There is now a new class specifically designed to hold register values: lldb_private::RegisterValue The new register context calls that subclasses must implement are: virtual bool ReadRegister (const RegisterInfo *reg_info, RegisterValue &reg_value) = 0; virtual bool WriteRegister (const RegisterInfo *reg_info, const RegisterValue &reg_value) = 0; The RegisterValue class must be big enough to handle any register value. The class contains an enumeration for the value type, and then a union for the data value. Any integer/float values are stored directly in an appropriate host integer/float. Anything bigger is stored in a byte buffer that has a length and byte order. The RegisterValue class also knows how to copy register value bytes into in a buffer with a specified byte order which can be used to write the register value down into memory, and this does the right thing when not all bytes from the register values are needed (getting a uint8 from a uint32 register value..). All RegiterContext and other sources have been switched over to using the new regiter value class. llvm-svn: 131096

* Got the EmulateInstruction CFI code a lot closer to producing CFI data.Greg Clayton2011-04-261-247/+212
| | | | | | | | | | | | | Switch the EmulateInstruction to use the standard RegisterInfo structure that is defined in the lldb private types intead of passing the reg kind and reg num everywhere. EmulateInstruction subclasses also need to provide RegisterInfo structs given a reg kind and reg num. This eliminates the need for the GetRegisterName() virtual function and allows more complete information to be passed around in the read/write register callbacks. Subclasses should always provide RegiterInfo structs with the generic register info filled in as well as at least one kind of register number in the RegisterInfo.kinds[] array. llvm-svn: 130256
* Changed the emulate instruction function to take emulate options whichGreg Clayton2011-04-261-89/+81
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | are defined as enumerations. Current bits include: eEmulateInstructionOptionAutoAdvancePC eEmulateInstructionOptionIgnoreConditions Modified the EmulateInstruction class to have a few more pure virtuals that can help clients understand how many instructions the emulator can handle: virtual bool SupportsEmulatingIntructionsOfType (InstructionType inst_type) = 0; Where instruction types are defined as: //------------------------------------------------------------------ /// Instruction types //------------------------------------------------------------------ typedef enum InstructionType { eInstructionTypeAny, // Support for any instructions at all (at least one) eInstructionTypePrologueEpilogue, // All prologue and epilogue instructons that push and pop register values and modify sp/fp eInstructionTypePCModifying, // Any instruction that modifies the program counter/instruction pointer eInstructionTypeAll // All instructions of any kind } InstructionType; This allows use to tell what an emulator can do and also allows us to request these abilities when we are finding the plug-in interface. Added the ability for an EmulateInstruction class to get the register names for any registers that are part of the emulation. This helps with being able to dump and log effectively. The UnwindAssembly class now stores the architecture it was created with in case it is needed later in the unwinding process. Added a function that can tell us DWARF register names for ARM that goes along with the source/Utility/ARM_DWARF_Registers.h file: source/Utility/ARM_DWARF_Registers.c Took some of plug-ins out of the lldb_private namespace. llvm-svn: 130189

* Modified the ArchSpec to take an optional "Platform *" when setting the triple.Greg Clayton2011-04-071-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | 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. llvm-svn: 129112

* Modified the PluginManager to be ready for loading plug-ins from a systemGreg Clayton2011-02-021-0/+26
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | LLDB plugin directory and a user LLDB plugin directory. We currently still need to work out at what layer the plug-ins will be, but at least we are prepared for plug-ins. Plug-ins will attempt to be loaded from the "/Developer/Library/PrivateFrameworks/LLDB.framework/Resources/Plugins" folder, and from the "~/Library/Application Support/LLDB/Plugins" folder on MacOSX. Each plugin will be scanned for: extern "C" bool LLDBPluginInitialize(void); extern "C" void LLDBPluginTerminate(void); If at least LLDBPluginInitialize is found, the plug-in will be loaded. The LLDBPluginInitialize function returns a bool that indicates if the plug-in should stay loaded or not (plug-ins might check the current OS, current hardware, or anything else and determine they don't want to run on the current host). The plug-in is uniqued by path and added to a static loaded plug-in map. The plug-in scanning happens during "lldb_private::Initialize()" which calls to the PluginManager::Initialize() function. Likewise with termination lldb_private::Terminate() calls PluginManager::Terminate(). The paths for the plug-in directories is fetched through new Host calls: bool Host::GetLLDBPath (ePathTypeLLDBSystemPlugins, dir_spec); bool Host::GetLLDBPath (ePathTypeLLDBUserPlugins, dir_spec); This way linux and other systems can define their own appropriate locations for plug-ins to be loaded. To allow dynamic shared library loading, the Host layer has also been modified to include shared library open, close and get symbol: static void * Host::DynamicLibraryOpen (const FileSpec &file_spec, Error &error); static Error Host::DynamicLibraryClose (void *dynamic_library_handle); static void * Host::DynamicLibraryGetSymbol (void *dynamic_library_handle, const char *symbol_name, Error &error); lldb_private::FileSpec also has been modified to support directory enumeration in an attempt to abstract the directory enumeration into one spot in the code. The directory enumertion function is static and takes a callback: typedef enum EnumerateDirectoryResult { eEnumerateDirectoryResultNext, // Enumerate next entry in the current directory eEnumerateDirectoryResultEnter, // Recurse into the current entry if it is a directory or symlink, or next if not eEnumerateDirectoryResultExit, // Exit from the current directory at the current level. eEnumerateDirectoryResultQuit // Stop directory enumerations at any level }; typedef FileSpec::EnumerateDirectoryResult (*EnumerateDirectoryCallbackType) (void *baton, FileSpec::FileType file_type, const FileSpec &spec); static FileSpec::EnumerateDirectoryResult FileSpec::EnumerateDirectory (const char *dir_path, bool find_directories, bool find_files, bool find_other, EnumerateDirectoryCallbackType callback, void *callback_baton); This allow clients to specify the directory to search, and specifies if only files, directories or other (pipe, symlink, fifo, etc) files will cause the callback to be called. The callback also gets to return with the action that should be performed after this directory entry. eEnumerateDirectoryResultNext specifies to continue enumerating through a directory with the next entry. eEnumerateDirectoryResultEnter specifies to recurse down into a directory entry, or if the file is not a directory or symlink/alias to a directory, then just iterate to the next entry. eEnumerateDirectoryResultExit specifies to exit the current directory and skip any entries that might be remaining, yet continue enumerating to the next entry in the parent directory. And finally eEnumerateDirectoryResultQuit means to abort all directory enumerations at all levels. Modified the Declaration class to not include column information currently since we don't have any compilers that currently support column based declaration information. Columns support can be re-enabled with the additions of a #define. Added the ability to find an EmulateInstruction plug-in given a target triple and optional plug-in name in the plug-in manager. Fixed a few cases where opendir/readdir was being used, but yet not closedir was being used. Soon these will be deprecated in favor of the new directory enumeration call that was added to the FileSpec class. llvm-svn: 124716
