use lldb_private::Target::ReadMemory(...) to allow constant strings
to be displayed in global variables prior on in between process
execution.
Centralized the variable declaration dumping into:
bool
Variable::DumpDeclaration (Stream *s, bool show_fullpaths, bool show_module);
Fixed an issue if you used "target variable --regex <regex>" where the
variable name would not be displayed, but the regular expression would.
Fixed an issue when viewing global variables through "target variable"
might not display correctly when doing DWARF in object files.

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.

Added a "bool show_fullpaths" to many more objects that were
previously always dumping full paths.
Fixed a few places where the DWARF was not indexed when we
we needed it to be when making queries. Also fixed an issue
where the DWARF in .o files wasn't searching all .o files
for the types.
Fixed an issue with the output from "image lookup --type <TYPENAME>"
where the name and byte size might not be resolved and might not
display. We now call the accessors so we end up seeing all of the
type info.

might dump file paths that allows the dumping of full paths or just the
basenames. Switched the stack frame dumping code to use just the basenames for
the files instead of the full path.
Modified the StackID class to no rely on needing the start PC for the current
function/symbol since we can use the SymbolContextScope to uniquely identify
that, unless there is no symbol context scope. In that case we can rely upon
the current PC value. This saves the StackID from having to calculate the
start PC when the StackFrame::GetStackID() accessor is called.
Also improved the StackID less than operator to correctly handle inlined stack
frames in the same stack.

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.
