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.

- Add ability to control whether or not the emulator advances the
PC register (in the emulation state), if the instruction itself
does not change the pc value..
- Fix a few typos in asm description strings.
- Fix bug in the carry flag calculation.

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.

Modified the Disassembler::Instruction base class to contain an Opcode
instance so that we can know the bytes for an instruction without needing
to keep the data around.
Modified the DisassemblerLLVM's instruction class to correctly extract the
opcode bytes if all goes well.

public types and public enums. This was done to keep the SWIG stuff from
parsing all sorts of enums and types that weren't needed, and allows us to
abstract our API better.

now, in addition to cpu type/subtype and architecture flavor, contains:
- byte order (big endian, little endian)
- address size in bytes
- llvm::Triple for true target triple support and for more powerful plug-in
selection.

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.
