6dde30e964 Added extensive logging of the code that is actually going
to be executed by the inferior.  This required explicit support
from RecordingMemoryManager for finding the address range
belonging to a particular function.

Also fixed a bug in DisassemblerLLVM where the disassembler
assumed there was an AddressRange available even when it was
NULL.

ebf7707e53 Modified TaggedASTType to inherit from ClangASTType
and moved it to its own header file for cleanliness.

Added more logging to ClangFunction so that we can
diagnose crashes in the executing expression.

Added code to extract the result of the expression
from the struct that is passed to the JIT-compiled
code.

8cf0593c87 Added a new enumeration named "ClangASTContext::AccessType" that abstracts the type creation from the various access enumerations in Clang. Currently there are clang::AccessSpecifier and the objective C ivars have their own enumeration. So I added a new enumeration that will allow a consistent interface when creating types through ClangASTContext.
I also added new functions to create an Objective C class, ivar and set an objective C superclass. They aren't hooked up in the DWARF parser yet. That is the next step, though I am unsure if I will do this in the DWARF parser or try and do it generically in the existing Record manipulation functions.

4ceb9980c8 Modified both the ObjectFileMachO and ObjectFileELF to correctly set the
SectionType for Section objects for DWARF.

Modified the DWARF plug-in to get the DWARF sections by SectionType so we
can safely abstract the LLDB core from section names for the various object
file formats.

Modified the SectionType definitions for .debug_pubnames and .debug_pubtypes
to use the correct case.

e1a916a74d Change over to using the definitions for mach-o types and defines to the
defines that are in "llvm/Support/MachO.h". This should allow ObjectFileMachO
and ObjectContainerUniversalMachO to be able to be cross compiled in Linux.

Also did some cleanup on the ASTType by renaming it to ClangASTType and
renaming the header file. Moved a lot of "AST * + opaque clang type *"
functionality from lldb_private::Type over into ClangASTType.

8c920840a4 Add new SectionType enumerations for all DWARF sections. ObjectFile parsers should start properly setting the section types for DWARF sections, then we can move the DWARF SymbolFile parser over to finding the sections by the appropriate SectionType.

1d18066411 Added functionality to dematerialize values that were
used by the JIT compiled expression, including the
result of the expression.

Also added a new class, ASTType, which encapsulates an
opaque Clang type and its associated AST context.

Refactored ClangExpressionDeclMap to use ASTTypes,
significantly reducing the possibility of mixups of
types from different AST contexts.

a56c800607 Add an "Avoid Frames matching this regular expression" to ThreadPlanStepInRange.
This relies on ThreadPlanStepOut working correctly, which it doesn't currently for Inlined functions, so this feature is only partially useful until we take care of Stepping Out of inlined functions.
Added an option to "thread step-in" to set the avoid regular expression.  This is mostly for testing, once the Setting code is redone, we'll move this to a general setting.

1308bb2791 Added a "GetRepeatCommand" to the command object. The Interpreter uses this

than relist the first listing...

279a6c2669 Hide the logic for command resolution for commands, aliases & user commands behind a single
interface so everybody does it the same way.  Add an "exact" lookup for internal uses.

Fix up a few little cases where we weren't reporting command lookup errors correctly.

Added "b" as an alias for "breakpoint" so it doesn't collide with "bt".

2ab712f212 Added the skeleton of an IR transformer that will
prepare IR for execution in the target.  Wired the

conversion to DWARF fails, and wired conversion to
DWARF to always fail (well, we don't generate any
DWARF...)

54b8b8c1a7 Fixed up disassembly to not emit the module name before all function names
that are in the disassembly comments since most of them are in the same
module (shared library).

Added an address dump style that shows the symbol context without the module
(used in the disassembly code).

dda4f7b520 Centralized all disassembly into static functions in source/Core/Disassembler.cpp.
Added the ability to read memory from the target's object files when we aren't
running, so disassembling works before you run!

Cleaned up the API to lldb_private::Target::ReadMemory().

Cleaned up the API to the Disassembler to use actual "lldb_private::Address"
objects instead of just an "addr_t". This is nice because the Address objects
when resolved carry along their section and module which can get us the 
object file. This allows Target::ReadMemory to be used when we are not 
running.

Added a new lldb_private::Address dump style: DumpStyleDetailedSymbolContext
This will show a full breakdown of what an address points to. To see some
sample output, execute a "image lookup --address <addr>".

Fixed SymbolContext::DumpStopContext(...) to not require a live process in
order to be able to print function and symbol offsets.

ebc1bb277c Add a unique ID to each debugger instance.
Add functions to look up debugger by id
Add global variable to lldb python module, to hold debugger id
Modify embedded Python interpreter to update the global variable with the
 id of its current debugger.
Modify the char ** typemap definition in lldb.swig to accept 'None' (for NULL)
 as a valid value.

The point of all this is so that, when you drop into the embedded interpreter
from the command interpreter (or when doing Python-based breakpoint commands),
there is a way for the Python side to find/get the correct debugger
instance ( by checking debugger_unique_id, then calling 
SBDebugger::FindDebuggerWithID  on it).

8d38ac4536 Fixed debug map in executable + DWARF in .o debugging on Mac OS X.
Added the ability to dump any file in the global module cache using any of
the "image dump" commands. This allows us to dump the .o files that are used
with DWARF + .o since they don't belong the the target list for the current
target.

0c5cd90d63 Added function name types to allow us to set breakpoints by name more
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.

6611103cfe Very large changes that were needed in order to allow multiple connections
to the debugger from GUI windows. Previously there was one global debugger
instance that could be accessed that had its own command interpreter and
current state (current target/process/thread/frame). When a GUI debugger
was attached, if it opened more than one window that each had a console
window, there were issues where the last one to setup the global debugger
object won and got control of the debugger.

To avoid this we now create instances of the lldb_private::Debugger that each 
has its own state:
- target list for targets the debugger instance owns
- current process/thread/frame
- its own command interpreter
- its own input, output and error file handles to avoid conflicts
- its own input reader stack

So now clients should call:

    SBDebugger::Initialize(); // (static function)

    SBDebugger debugger (SBDebugger::Create());
    // Use which ever file handles you wish
    debugger.SetErrorFileHandle (stderr, false);
    debugger.SetOutputFileHandle (stdout, false);
    debugger.SetInputFileHandle (stdin, true);

    // main loop
    
    SBDebugger::Terminate(); // (static function)
    
SBDebugger::Initialize() and SBDebugger::Terminate() are ref counted to
ensure nothing gets destroyed too early when multiple clients might be
attached.

Cleaned up the command interpreter and the CommandObject and all subclasses
to take more appropriate arguments.
