Greg Clayton f4b47e1579 Abtracted the old "lldb_private::Thread::StopInfo" into an abtract class.
This will allow debugger plug-ins to make any instance of "lldb_private::StopInfo"
that can completely describe any stop reason. It also provides a framework for
doing intelligent things with the stop info at important times in the lifetime
of the inferior. 

Examples include the signal stop info in StopInfoUnixSignal. It will check with
the process to see that the current action is for the signal. These actions
include wether to stop for the signal, wether the notify that the signal was
hit, and wether to pass the signal along to the inferior process. The 
StopInfoUnixSignal class overrides the "ShouldStop()" method of StopInfo and
this allows the stop info to determine if it should stop at the signal or 
continue the process. 


StopInfo subclasses must override the following functions:

    virtual lldb::StopReason
    GetStopReason () const = 0;

    virtual const char *
    GetDescription () = 0;


StopInfo subclasses can override the following functions:


    // If the subclass returns "false", the inferior will resume. The default
    // version of this function returns "true" which means the default stop
    // info will stop the process. The breakpoint subclass will check if
    // the breakpoint wants us to stop by calling any installed callback on
    // the breakpoint, and also checking if the breakpoint is for the current
    // thread. Signals will check if they should stop based off of the 
    // UnixSignal settings in the process.
    virtual bool
    ShouldStop (Event *event_ptr);

    // Sublasses can state if they want to notify the debugger when "ShouldStop"
    // returns false. This would be handy for breakpoints where you want to
    // log information and continue and is also used by the signal stop info
    // to notify that a signal was received (after it checks with the process
    // signal settings).
    virtual bool
    ShouldNotify (Event *event_ptr)
    {
        return false;
    }

    // Allow subclasses to do something intelligent right before we resume.
    // The signal class will figure out if the signal should be propagated
    // to the inferior process and pass that along to the debugger plug-ins.
    virtual void
    WillResume (lldb::StateType resume_state)
    {
        // By default, don't do anything
    }


The support the Mach exceptions was moved into the lldb/source/Plugins/Process/Utility
folder and now doesn't polute the lldb_private::Thread class with platform
specific code.

Greg Clayton b0b9fe610a Added support for objective C built-in types: id, Class, and SEL. This
involved watching for the objective C built-in types in DWARF and making sure
when we convert the DWARF types into clang types that we use the appropriate
ASTContext types.

Added a way to find and dump types in lldb (something equivalent to gdb's 
"ptype" command):

    image lookup --type <TYPENAME>

This only works for looking up types by name and won't work with variables.
It also currently dumps out verbose internal information. I will modify it
to dump more appropriate user level info in my next submission.

Hookup up the "FindTypes()" functions in the SymbolFile and SymbolVendor so
we can lookup types by name in one or more images.

Fixed "image lookup --address <ADDRESS>" to be able to correctly show all
symbol context information, but it will only show this extra information when
the new "--verbose" flag is used.

Updated to latest LLVM to get a few needed fixes.

Greg Clayton aaa58c6679 Added a new utility class that I have wanted for a while. The CleanUp
class is a templatized class that allows you to have a cleanup function called
on a data value of type T when the value is set or when the object goes
out of scope. It has support for very rudimentary invalid value detection that
can be enabled by using the appropriate constructor. 

Anyone with template experience that can see ways of improving this class
please let me know. The example code shows a few typical scenarios in which
I would like to use it. It is currently coded with simple type T values
in mind (integer file descriptors, pointers, etc), but I am sure some 
specialization might help out the class for more complex types.

There is a lot of documentation including examples in the CleanUp.h header 
file.

Sean Callanan 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.

Greg Clayton 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.

Sean Callanan 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.

Sean Callanan 2ab712f212 Added the skeleton of an IR transformer that will
prepare IR for execution in the target.  Wired the
expression command to use this IR transformer when
conversion to DWARF fails, and wired conversion to
DWARF to always fail (well, we don't generate any
DWARF...)

Sean Callanan 2df8a1f39c Added the skeleton of a transformation pass to
convert IR to DWARF.  So far, this pass only
performs a depth-first traversal of the IR,
logging each basic block as it finds it.

Sean Callanan 116be5347e Added a SemaConsumer that transforms the ASTs for

Greg Clayton 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.

Greg Clayton 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.

Jim Ingham b01e742af7 Two changes in this checkin. Added a ThreadPlanKind so that I can do some reasoning based on the kind of thread plan
without having to use RTTI.
Removed the ThreadPlanContinue and replaced with a ShouldAutoContinue query that serves the same purpose.  Having to push
another plan to assert that if there's no other indication the target should continue when this plan is popped was flakey
and error prone.  This method is more stable, and fixed problems we were having with thread specific breakpoints.

Caroline Tice d6ac38485b Parameterize the shell scripts for creating and copying the python and

Jim Ingham 1b54c88cc4 Add a "thread specification" class that specifies thread specific breakpoints by name, index, queue or TID.
Push this through all the breakpoint management code.  Allow this to be set when the breakpoint is created.
Fix the Process classes so that a breakpoint hit that is not for a particular thread is not reported as a 
breakpoint hit event for that thread.
Added a "breakpoint configure" command to allow you to reset any of the thread 
specific options (or the ignore count.)

Greg Clayton ef59f829e4 Switched over to using the new lldb::SharingPtr from Howard Hinnant.
We need to put this in LLDB since we need to vend this in our API
because our public API uses shared pointers to our private objects.

Removed a deprecated file: include/lldb/Host/Types.h

Greg Clayton 41f923275e Made lldb_private::ArchSpec more generic so that it can take a mach-o cpu
type and sub-type, or an ELF e_machine value. Also added a generic CPU type
to the arch spec class so we can have a single arch definition that the LLDB
core code can use. Previously a lot of places in the code were using the
mach-o definitions from a macosx header file. 

Switches over to using "llvm/Support/MachO.h" for the llvm::MachO::XXX for the
CPU types and sub types for mach-o ArchSpecs. Added "llvm/Support/ELF.h" so 
we can use the "llvm::ELF::XXX" defines for the ELF ArchSpecs.

Got rid of all CPU_TYPE_ and CPU_SUBTYPE_ defines that were previously being
used in LLDB.
