Caroline Tice 3df9a8dfd7 This is a very large commit that completely re-does the way lldb
handles user settable internal variables (the equivalent of set/show
variables in gdb).  In addition to the basic infrastructure (most of
which is defined in UserSettingsController.{h,cpp}, there are examples
of two classes that have been set up to contain user settable
variables (the Debugger and Process classes).  The 'settings' command
has been modified to be a command-subcommand structure, and the 'set',
'show' and 'append' commands have been moved into this sub-commabnd
structure.  The old StateVariable class has been completely replaced
by this, and the state variable dictionary has been removed from the
Command Interpreter.  Places that formerly accessed the state variable
mechanism have been modified to access the variables in this new
structure instead (checking the term-width; getting/checking the
prompt; etc.)

Variables are attached to classes; there are two basic "flavors" of
variables that can be set: "global" variables (static/class-wide), and
"instance" variables (one per instance of the class).  The whole thing
has been set up so that any global or instance variable can be set at
any time (e.g. on start up, in your .lldbinit file), whether or not
any instances actually exist (there's a whole pending and default
values mechanism to help deal with that).

Greg Clayton 2cad65a595 Fixed the StackFrame to correctly resolve the StackID's SymbolContextScope.
Added extra logging for stepping.

Fixed an issue where cached stack frame data could be lost between runs when
the thread plans read a stack frame.

Greg Clayton 6dadd508e7 Added a new bool parameter to many of the DumpStopContext() methods that
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.

Greg Clayton 288bdf9c1d StackFrame objects now own ValueObjects for any frame variables (locals, args,
function statics, file globals and static variables) that a frame contains. 
The StackFrame objects can give out ValueObjects instances for
each variable which allows us to track when a variable changes and doesn't
depend on variable names when getting value objects.

StackFrame::GetVariableList now takes a boolean to indicate if we want to
get the frame compile unit globals and static variables.

The value objects in the stack frames can now correctly track when they have
been modified. There are a few more tweaks needed to complete this work. The
biggest issue is when stepping creates partial stacks (just frame zero usually)
and causes previous stack frames not to match up with the current stack frames
because the previous frames only has frame zero. We don't really want to 
require that all previous frames be complete since stepping often must check
stack frames to complete their jobs. I will fix this issue tomorrow.

Sean Callanan 8e999e4015 Added code to run pointer validation checks in

just now the crash will be in the function
___clang_valid_pointer_check().

Sean Callanan 6961e87847 Added support for dynamic sanity checking in
expressions.  Values used by the expression are
checked by validation functions which cause the
program to crash if the values are unsafe.

Major changes:

- Added IRDynamicChecks.[ch], which contains the
  core code related to this feature

- Modified CommandObjectExpression to install the
  validator functions into the target process.

- Added an accessor to Process that gets/sets the
  helper functions

Sean Callanan 823bb4cc24 Fixed a bug where the parser-specific members of
persistent variables were staying around too long.
This caused the following problem:

- A persistent result variable is created for the
  result of an expression.  The pointer to the
  corresponding Decl is stored in the variable.

- The persistent variable is looked up during
  struct generation (correctly) using its Decl.

- Another expression defines a new result variable
  which happens to have a Decl in the same place
  as the original result variable.

- The persistent variable is looked up during
  struct generation using its Decl, but the old
  result variable appears first in the list and
  has the same Decl pointer.

The fix is to destroy parser-specific data when
it is no longer valid.

Also improved some logging as I diagnosed the
bug.

Greg Clayton 59e8fc1c74 Clarified the intent of the SymbolContextScope class in the header
documentation. Symbol now inherits from the symbol
context scope so that the StackID can use a "SymbolContextScope *"
instead of a blockID (which could have been the same as some other
blockID from another symbol file). 

Modified the stacks that are created on subsequent stops to reuse
the previous stack frame objects which will allow for some internal
optimization using pointer comparisons during stepping.

Sean Callanan e71d553cd4 Added a ClangUtilityFunction class that allows the
debugger to insert self-contained functions for use by
expressions (mainly for error-checking).

In order to support detecting whether a crash occurred
in one of these helpers -- currently our preferred way
of reporting that an error-check failed -- added a bit
of support for getting the extent of a JITted function
in addition to just its base.

Greg Clayton 68275d5e56 Made it so we update the current frames from the previous frames by doing STL
swaps on the variable list, value object list, and disassembly. This avoids
us having to try and update frame indexes and other things that were getting
out of sync.

llvm-svn: 112301
2010-08-27 21:47:54 +00:00
Greg Clayton 5082c5fdf6 Simplified the StackFrameList class down to a single frames list again
instead of trying to maintain the real frame list (unwind frames) and an
inline frame list. The information is cheap to produce when we already have
looked up a block and was making stack frame uniquing difficult when trying
to use the previous stack when making the current stack.

We now maintain the previous value object lists for common frames between
a previous and current frames so we will be able to tell when variable values
change.

Sean Callanan 1a8d40935d This is a major refactoring of the expression parser.
The goal is to separate the parser's data from the data
belonging to the parser's clients.  This allows clients
to use the parser to obtain (for example) a JIT compiled
function or some DWARF code, and then discard the parser
state.

Previously, parser state was held in ClangExpression and
used liberally by ClangFunction, which inherited from
ClangExpression.  The main effects of this refactoring 
are:

- reducing ClangExpression to an abstract class that
  declares methods that any client must expose to the
  expression parser,

- moving the code specific to implementing the "expr"
  command from ClangExpression and
  CommandObjectExpression into ClangUserExpression,
  a new class,

- moving the common parser interaction code from
  ClangExpression into ClangExpressionParser, a new
  class, and

- making ClangFunction rely only on
  ClangExpressionParser and not depend on the
  internal implementation of ClangExpression.

Side effects include:

- the compiler interaction code has been factored
  out of ClangFunction and is now in an AST pass
  (ASTStructExtractor),

- the header file for ClangFunction is now fully
  documented,

- several bugs that only popped up when Clang was
  deallocated (which never happened, since the
  lifetime of the compiler was essentially infinite)
  are now fixed, and

- the developer-only "call" command has been
  disabled.

I have tested the expr command and the Objective-C
step-into code, which use ClangUserExpression and
ClangFunction, respectively, and verified that they
work.  Please let me know if you encounter bugs or
poor documentation.

a section offset address.

Jim Ingham 2976d00adb Change "Current" as in GetCurrentThread, GetCurrentStackFrame, etc, to "Selected" i.e. GetSelectedThread. Selected makes more sense, since these are set by some user action (a selection). I didn't change "CurrentProcess" since this is always controlled by the target, and a given target can only have one process, so it really can't be selected.

Greg Clayton 0445d8f498 Cleaned up the inline stack frame code one more time to prepare for inlined
code stepping. Also we now store the stack frames for the current and previous
stops in the thread in std::auto_ptr objects. When we create a thread stack
frame list we pass the previous frame into it so it can re-use the frames
and maintain will allow for variable changes to be detected. I will implement
the stack frame reuse next.

Greg Clayton 158483cf62 Thread no longer needs to be a friend in StackFrameList now that StackFrameList
contains the entire stack backtrace.

llvm-svn: 112009
2010-08-25 00:58:59 +00:00
Greg Clayton 12daf946c8 Cleaned up the inline backtrace code even more by moving all stack backtracing
functionality into StackFrameList. This will allow us to copy the previous
stack backtrace from the previous stop into another variable so we can re-use
as much as possible from the previous stack backtrace.

llvm-svn: 112007
2010-08-25 00:35:26 +00:00
Greg Clayton 288e5afe6b Fixed another issue with the inline stack frames where if the first frame
has inlined functions that all started at the same address, then the inlined
backtrace would not produce correct stack frames.

Also cleaned up and inlined a lot of stuff in lldb_private::Address.

Added a function to StackFrame to detect if the frame is a concrete frame so
we can detect the difference between actual frames and inlined frames.

llvm-svn: 111989
2010-08-24 22:59:52 +00:00
Greg Clayton 9da7bd0739 Got a lot of the kinks worked out in the inline support after debugging more
complex inlined examples.

StackFrame classes don't have a "GetPC" anymore, they have "GetFrameCodeAddress()".
This is because inlined frames will have a PC value that is the same as the 
concrete frame that owns the inlined frame, yet the code locations for the
frame can be different. We also need to be able to get the real PC value for
a given frame so that variables evaluate correctly. To get the actual PC
value for a frame you can use:

    addr_t pc = frame->GetRegisterContext()->GetPC();

Some issues with the StackFrame stomping on its own symbol context were 
resolved which were causing the information to change for a frame when the
stack ID was calculated. Also the StackFrame will now correctly store the
symbol context resolve flags for any extra bits of information that were 
looked up (if you ask for a block only and you find one, you will alwasy have
the compile unit and function).

llvm-svn: 111964
2010-08-24 21:05:24 +00:00
Greg Clayton bba1ba8575 Clear the inline stack frame info when we clean all stack frames.
llvm-svn: 111891
2010-08-24 01:28:00 +00:00
Greg Clayton 1b72fcb7d1 Added support for inlined stack frames being represented as real stack frames
which is now on by default. Frames are gotten from the unwinder as concrete
frames, then if inline frames are to be shown, extra information to track
and reconstruct these frames is cached with each Thread and exanded as needed.

I added an inline height as part of the lldb_private::StackID class, the class
that helps us uniquely identify stack frames. This allows for two frames to
shared the same call frame address, yet differ only in inline height.

Fixed setting breakpoint by address to not require addresses to resolve.

A quick example:

% cat main.cpp

Current executable set to 'test/stl/a.out' (x86_64).

Each inline frame contains only the variables that they contain and each inlined
stack frame is treated as a single entity.

Greg Clayton 0b76a2c21f Modified the host process monitor callback function Host::StartMonitoringChildProcess
to spawn a thread for each process that is being monitored. Previously
LLDB would spawn a single thread that would wait for any child process which
isn't ok to do as a shared library (LLDB.framework on Mac OSX, or lldb.so on
linux). The old single thread used to call wait4() with a pid of -1 which 
could cause it to reap child processes that it shouldn't have.

Re-wrote the way Function blocks are handles. Previously I attempted to keep
all blocks in a single memory allocation (in a std::vector). This made the
code somewhat efficient, but hard to work with. I got rid of the old BlockList
class, and went to a straight parent with children relationship. This new 
approach will allow for partial parsing of the blocks within a function.

Sean Callanan d0ef0eff61 First step of refactoring variable handling in the

ClangPersistentVariable has been removed; we now

Jim Ingham 87c1191e0e Now that we are using the Unwinder (or Jason's new unwinder when that comes about) all the plugin-specific details of getting stack frames
should be hidden behind that, and the "GetStackFrameAtIndex" and "GetStackFrameCount" algorithms become generic.  So I moved them to Thread.cpp.

llvm-svn: 110899
2010-08-12 02:14:28 +00:00
Sean Callanan d1e5b439c9 Added automatically generated result variables for each
expression.  It is now possible to do things like this:

(lldb) expr int $i = 5; $i + 1
$0 = (int) 6
(lldb) expr $i + 3
$1 = (int) 8
(lldb) expr $1 + $0
$2 = (int) 14

As a bonus, this allowed us to move printing of
expression results into the ClangPersistentVariable
class.  This code needs a bit of refactoring -- in
particular, ClangExpressionDeclMap has eaten one too
many bacteria and needs to undergo mitosis -- but the
infrastructure appears to be holding up nicely.

llvm-svn: 110896
2010-08-12 01:56:52 +00:00
Sean Callanan 2235f32bbd Added support for persistent variables to the

(lldb) expr int $i = 5; $i + 1
(int) 6
(lldb) expr $i + 2
(int) 7

The skeleton for automatic result variables is
also implemented.  The changes affect:

- the process, which now contains a 
  ClangPersistentVariables object that holds
  persistent variables associated with it
- the expression parser, which now uses
  the persistent variables during variable
  lookup
- TaggedASTType, where I loaded some commonly
  used tags into a header so that they are
  interchangeable between different clients of
  the class

Add a completer for "process attach -n".

Caveats: there isn't currently a way to handle multiple processes with the same name.  That
will have to wait on a way to pass annotations along with the completion strings.

Sean Callanan fc16cc0a0c Removed the -i option from the expr command, and
made IR-based expression evaluation the default.

Also added a new class to hold persistent variables.
The class is empty as yet while I write up a design
document for what it will do.  Also the place where
it is currently created (by the Expression command)
is certainly wrong.

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.

llvm-svn: 110184
2010-08-04 01:40:35 +00:00
Sean Callanan 5666b674f3 Added support for accessing members of C++ objects,
including superclass members.  This involved ensuring
that access control was ignored, and ensuring that
the operands of BitCasts were properly scanned for
variables that needed importing.

Also laid the groundwork for declaring objects of
custom types; however, this functionality is disabled
for now because of a potential loop in ASTImporter.

llvm-svn: 110174
2010-08-04 01:02:13 +00:00
Greg Clayton 3504eee8a8 Added FindTypes to Module and ModuleList.
llvm-svn: 110093
2010-08-03 01:26:16 +00:00
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.

llvm-svn: 110089
2010-08-03 00:35:52 +00:00
Sean Callanan 5300d37aa7 Added support for rewriting objc_msgSend so we can
call Objective-C methods from expressions.  Also added
some more logging to the function-calling thread plan
so that we can see the registers when a function
finishes.

Also documented things maybe a bit better.

llvm-svn: 109938
2010-07-31 01:32:05 +00:00
Johnny Chen 7dc2e4784e We can do better when reporting the status of one-liner script execution.
Change the prototype of ScriptInterpreter::ExecuteOneLine() to return bool

Greg Clayton 9e40956aea Created lldb::LanguageType by moving an enumeration from the
lldb_private::Language class into the enumerations header so it can be freely
used by other interfaces.

Added correct objective C class support to the DWARF symbol parser. Prior to
this fix we were parsing objective C classes as C++ classes and now that the
expression parser is ready to call functions we need to make sure the objective
C classes have correct AST types.

llvm-svn: 109574
2010-07-28 02:04:09 +00:00
Sean Callanan cc54bd3cef Added and improved logging. This is helping us as we

2010-07-28 01:00:59 +00:00
Sean Callanan 7ea3501bd8 Added support for calling functions from expressions.
Right now we mock up the function as a variadic
function when generating the IR for the call; we need
to eventually make the function be the right type if
the type is available.

llvm-svn: 109543
2010-07-27 21:39:39 +00:00
Sean Callanan 4edba2d130 Added support for locating a function that is
referenced in the IR.  We don't yet support updating
the call to that function.

llvm-svn: 109483
2010-07-27 02:07:53 +00:00
Sean Callanan 8ade104a0a Changed SymbolContext so when you search for functions
it returns a list of functions as a SymbolContextList.

Rewrote the clients of SymbolContext to use this
SymbolContextList.

Rewrote some of the providers of the data to SymbolContext
to make them respect preferences as to whether the list
should be cleared first; propagated that change out.

ClangExpressionDeclMap and ClangASTSource use this new
function list to properly generate function definitions -
even for functions that don't have a prototype in the
debug information.

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 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.

llvm-svn: 109209
2010-07-23 02:19:15 +00:00
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.

llvm-svn: 109199
2010-07-23 00:16:21 +00:00
Greg Clayton 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.

llvm-svn: 109130
2010-07-22 18:30:50 +00:00
Greg Clayton 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.

llvm-svn: 109054
2010-07-21 22:54:26 +00:00
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.

llvm-svn: 109046
2010-07-21 22:12:05 +00:00
Greg Clayton 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.

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.

Jim Ingham 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.

Jim Ingham ebc09c36e9 Fix GetRepeatCommand so it works with multi-word commands.
Move the "source", "alias", and "unalias" commands to "commands *".
Move "source-file" to "source list".

llvm-svn: 107751
2010-07-07 03:36:20 +00:00
Jim Ingham 1308bb2791 Added a "GetRepeatCommand" to the command object. The Interpreter uses this
instead of the last history item to provide a command for the "empty" command.
Use this in the source-file command to make <RETURN> continue the listing rather
than relist the first listing...

llvm-svn: 107736
2010-07-06 23:48:33 +00:00
Jim Ingham 279a6c2669 Hide the logic for command resolution for commands, aliases & user commands behind a single

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".

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

DWARF...)

llvm-svn: 107559
2010-07-03 01:35:46 +00:00
Sean Callanan 2df8a1f39c Added the skeleton of a transformation pass to

Greg Clayton 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). 

Fixed a crasher that could happen when disassembling special section data.

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

llvm-svn: 107366
2010-07-01 01:26:43 +00:00
Greg Clayton 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.

llvm-svn: 107350

Caroline Tice 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).

llvm-svn: 107287
2010-06-30 16:22:25 +00:00
Jim Ingham 558ce124eb Add a source file completer to the CommandCompleters.

2010-06-30 05:02:46 +00:00
Greg Clayton 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.

llvm-svn: 107100
2010-06-28 23:51:11 +00:00
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.

Jim Ingham 0136309f5a Change the Breakpoint & BreakpointLocation GetDescription methods so they call the BreakpointOptions::GetDescription rather

around to keep the breakpoint listing from getting too verbose.

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 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.
