Cleaned up many error codes. For any who is filling in error strings into
lldb_private::Error objects the rules are:
- short strings that don't start with a capitol letter unless the name is a
class or anything else that is always capitolized
- no trailing newline character
- should be one line if possible

Implemented a first pass at adding "--gdb-format" support to anything that
accepts format with optional size/count.

Moved lldb::user_id_t values to be 64 bit. This was going to be needed for
process IDs, and thread IDs, but was mainly needed for for the UserID's for
Types so that DWARF with debug map can work flawlessly. With DWARF in .o files
the type ID was the DIE offset in the DWARF for the .o file which is not
unique across all .o files, so now the SymbolFileDWARFDebugMap class will
make the .o file index part (the high 32 bits) of the unique type identifier
so it can uniquely identify the types.

Added to the public API to allow symbolication:
- New SBSection objects that are object file sections which can be accessed
through the SBModule classes. You can get the number of sections, get a
section at index, and find a section by name.
- SBSections can contain subsections (first find "__TEXT" on darwin, then
us the resulting SBSection to find "__text" sub section).
- Set load addresses for a SBSection in the SBTarget interface
- Set the load addresses of all SBSection in a SBModule in the SBTarget interface
- Add a new module the an existing target in the SBTarget interface
- Get a SBSection from a SBAddress object

This should get us a lot closer to being able to symbolicate using LLDB through
the public API.

Converted the lldb_private::Process over to use the intrusive
shared pointers.

Changed the ExecutionContext over to use shared pointers for
the target, process, thread and frame since these objects can
easily go away at any time and any object that was holding onto
an ExecutionContext was running the risk of using a bad object.

Now that the shared pointers for target, process, thread and
frame are just a single pointer (they all use the instrusive
shared pointers) the execution context is much safer and still
the same size.

Made the shared pointers in the the ExecutionContext class protected
and made accessors for all of the various ways to get at the pointers,
references, and shared pointers.

Patch for "process load" by Filipe Cabecinhas.

Filipe was attempting to do a:

(lldb) process load ~/path/foo.dylib

But the process load command wasn't resolving the path. We have to be careful
about resolving the path here because we want to do it in terms of the platform
we are using. the "~/" can mean a completely different path if you are remotely
debugging on another machine as another user. So to support this, platforms now
can resolve remote paths:

bool
Platform::ResolveRemotePath (const FileSpec &platform_path,
FileSpec &resolved_platform_path);

The host/local platform will just resolve the path.

Added the ability to remove orphaned module shared pointers from a ModuleList.
This is helping us track down some extra references to ModuleSP objects that
are causing things to get kept around for too long.

Added a module pointer accessor to target and change a lot of code to use
it where it would be more efficient.

"taret delete" can now specify "--clean=1" which will cleanup the global module
list for any orphaned module in the shared module cache which can save memory
and also help track down module reference leaks like we have now.

Cleanup errors that come out of commands and make sure they all have newlines
_only_ in the resulting stream, not in the error objects (lldb_private::Error).
lldb_private::Error objects should always just have an error string with no
terminating newline characters or periods.

Fixed an issue with GDB remote packet detection that could end up deadlocking
if a full packet wasn't received in one chunk. Also modified the packet
checking function to properly toss one or more bytes when it detects bad
data.

Added new OptionGroup classes for UInt64, UUID, File and Boolean values.

Removed the "image" command and moved it to "target modules". Added an alias
for "image" to "target modules".

Added some new target commands to be able to add and load modules to a target:
(lldb) target modules add <path>
(lldb) target modules load [--file <path>] [--slide <offset>] [<sect-name> <sect-load-addr> ...]

So you can load individual sections without running a target:

(lldb) target modules load --file /usr/lib/libSystem.B.dylib __TEXT 0x7fccc80000 __DATA 0x1234000000

Or you can rigidly slide an entire shared library:

(lldb) target modules load --file /usr/lib/libSystem.B.dylib --slid 0x7fccc80000

This should improve bare board debugging when symbol files need to be slid around manually.

# 7260f620 18-Apr-2011 Greg Clayton <gclayton@apple.com>

Centralized a lot of the status information for processes,
threads, and stack frame down in the lldb_private::Process,
lldb_private::Thread, lldb_private::StackFrameList and the
lldb_private::StackF

Centralized a lot of the status information for processes,
threads, and stack frame down in the lldb_private::Process,
lldb_private::Thread, lldb_private::StackFrameList and the
lldb_private::StackFrame classes. We had some command line
commands that had duplicate versions of the process status
output ("thread list" and "process status" for example).

Removed the "file" command and placed it where it should
have been: "target create". Made an alias for "file" to
"target create" so we stay compatible with GDB commands.

We can now have multple usable targets in lldb at the
same time. This is nice for comparing two runs of a program
or debugging more than one binary at the same time. The
new command is "target select <target-idx>" and also to see
a list of the current targets you can use the new "target list"
command. The flow in a debug session can be:

(lldb) target create /path/to/exe/a.out
(lldb) breakpoint set --name main
(lldb) run
... hit breakpoint
(lldb) target create /bin/ls
(lldb) run /tmp
Process 36001 exited with status = 0 (0x00000000)
(lldb) target list
Current targets:
target #0: /tmp/args/a.out ( arch=x86_64-apple-darwin, platform=localhost, pid=35999, state=stopped )
* target #1: /bin/ls ( arch=x86_64-apple-darwin, platform=localhost, pid=36001, state=exited )
(lldb) target select 0
Current targets:
* target #0: /tmp/args/a.out ( arch=x86_64-apple-darwin, platform=localhost, pid=35999, state=stopped )
target #1: /bin/ls ( arch=x86_64-apple-darwin, platform=localhost, pid=36001, state=exited )
(lldb) bt
* thread #1: tid = 0x2d03, 0x0000000100000b9a a.out`main + 42 at main.c:16, stop reason = breakpoint 1.1
frame #0: 0x0000000100000b9a a.out`main + 42 at main.c:16
frame #1: 0x0000000100000b64 a.out`start + 52

Above we created a target for "a.out" and ran and hit a
breakpoint at "main". Then we created a new target for /bin/ls
and ran it. Then we listed the targest and selected our original
"a.out" program, so we showed two concurent debug sessions
going on at the same time.

Added two new classes for command options:

lldb_private::OptionGroup
lldb_private::OptionGroupOptions

OptionGroup lets you define a class that encapsulates settings that you want
to reuse in multiple commands. It contains only the option definitions and the
ability to set the option values, but it doesn't directly interface with the
lldb_private::Options class that is the front end to all of the CommandObject
option parsing. For that the OptionGroupOptions class can be used. It aggregates
one or more OptionGroup objects and directs the option setting to the
appropriate OptionGroup class. For an example of this, take a look at the
CommandObjectFile and how it uses its "m_option_group" object shown below
to be able to set values in both the FileOptionGroup and PlatformOptionGroup
classes. The members used in CommandObjectFile are:

OptionGroupOptions m_option_group;
FileOptionGroup m_file_options;
PlatformOptionGroup m_platform_options;

Then in the constructor for CommandObjectFile you can combine the option
settings. The code below shows a simplified version of the constructor:

CommandObjectFile::CommandObjectFile(CommandInterpreter &interpreter) :
CommandObject (...),
m_option_group (interpreter),
m_file_options (),
m_platform_options(true)
{
m_option_group.Append (&m_file_options);
m_option_group.Append (&m_platform_options);
m_option_group.Finalize();
}

We append the m_file_options and then the m_platform_options and then tell
the option group the finalize the results. This allows the m_option_group to
become the organizer of our prefs and after option parsing we end up with
valid preference settings in both the m_file_options and m_platform_options
objects. This also allows any other commands to use the FileOptionGroup and
PlatformOptionGroup classes to implement options for their commands.

Renamed:
virtual void Options::ResetOptionValues();
to:
virtual void Options::OptionParsingStarting();

And implemented a new callback named:

virtual Error Options::OptionParsingFinished();

This allows Options subclasses to verify that the options all go together
after all of the options have been specified and gives the chance for the
command object to return an error. It also gives a chance to take all of the
option values and produce or initialize objects after all options have
completed parsing.

Modfied:

virtual Error
SetOptionValue (int option_idx, const char *option_arg) = 0;

to be:

virtual Error
SetOptionValue (uint32_t option_idx, const char *option_arg) = 0;

(option_idx is now unsigned).

Moved the execution context that was in the Debugger into
the CommandInterpreter where it was always being used.

Make sure that Modules can track their object file offsets correctly to
allow opening of sub object files (like the "__commpage" on darwin).

Modified the Platforms to be able to launch processes. The first part of this
move is the platform soon will become the entity that launches your program
and when it does, it uses a new ProcessLaunchInfo class which encapsulates
all process launching settings. This simplifies the internal APIs needed for
launching. I want to slowly phase out process launching from the process
classes, so for now we can still launch just as we used to, but eventually
the platform is the object that should do the launching.

Modified the Host::LaunchProcess in the MacOSX Host.mm to correctly be able
to launch processes with all of the new eLaunchFlag settings. Modified any
code that was manually launching processes to use the Host::LaunchProcess
functions.

Fixed an issue where lldb_private::Args had implicitly defined copy
constructors that could do the wrong thing. This has now been fixed by adding
an appropriate copy constructor and assignment operator.

Make sure we don't add empty ModuleSP entries to a module list.

Fixed the commpage module creation on MacOSX, but we still need to train
the MacOSX dynamic loader to not get rid of it when it doesn't have an entry
in the all image infos.

Abstracted many more calls from in ProcessGDBRemote down into the
GDBRemoteCommunicationClient subclass to make the classes cleaner and more
efficient.

Fixed the default iOS ARM register context to be correct and also added support
for targets that don't support the qThreadStopInfo packet by selecting the
current thread (only if needed) and then sending a stop reply packet.

Debugserver can now start up with a --unix-socket (-u for short) and can
then bind to port zero and send the port it bound to to a listening process
on the other end. This allows the GDB remote platform to spawn new GDB server
instances (debugserver) to allow platform debugging.

Modified the ArchSpec to take an optional "Platform *" when setting the triple.
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.

Many improvements to the Platform base class and subclasses. The base Platform
class now implements the Host functionality for a lot of things that make
sense by default so that subclasses can check:

int
PlatformSubclass::Foo ()
{
if (IsHost())
return Platform::Foo (); // Let the platform base class do the host specific stuff

// Platform subclass specific code...
int result = ...
return result;
}

Added new functions to the platform:

virtual const char *Platform::GetUserName (uint32_t uid);
virtual const char *Platform::GetGroupName (uint32_t gid);

The user and group names are cached locally so that remote platforms can avoid
sending packets multiple times to resolve this information.

Added the parent process ID to the ProcessInfo class.

Added a new ProcessInfoMatch class which helps us to match processes up
and changed the Host layer over to using this new class. The new class allows
us to search for processs:
1 - by name (equal to, starts with, ends with, contains, and regex)
2 - by pid
3 - And further check for parent pid == value, uid == value, gid == value,
euid == value, egid == value, arch == value, parent == value.

This is all hookup up to the "platform process list" command which required
adding dumping routines to dump process information. If the Host class
implements the process lookup routines, you can now lists processes on
your local machine:

machine1.foo.com % lldb
(lldb) platform process list

This of course also works remotely with the lldb-platform:

The lldb-platform implements everything with the Host:: layer, so this should
"just work" for linux. I will probably be adding more stuff to the Host layer
for launching processes and attaching to processes so that this support should
eventually just work as well.

Modified the target to be able to be created with an architecture that differs
from the main executable. This is needed for iOS debugging since we can have
an "armv6" binary which can run on an "armv7" machine, so we want to be able
to do:

% lldb
(lldb) platform create remote-ios
(lldb) file --arch armv7 a.out

Where "a.out" is an armv6 executable. The platform then can correctly decide
to open all "armv7" images for all dependent shared libraries.

Modified the disassembly to show the current PC value. Example output:

(lldb) disassemble --frame
a.out`main:
0x1eb7: pushl %ebp
0x1eb8: movl %esp, %ebp
0x1eba: pushl %ebx
0x1ebb: subl $20, %esp
0x1ebe: calll 0x1ec3 ; main + 12 at test.c:18
0x1ec3: popl %ebx
-> 0x1ec4: calll 0x1f12 ; getpid
0x1ec9: movl %eax, 4(%esp)
0x1ecd: leal 199(%ebx), %eax
0x1ed3: movl %eax, (%esp)
0x1ed6: calll 0x1f18 ; printf
0x1edb: leal 213(%ebx), %eax
0x1ee1: movl %eax, (%esp)
0x1ee4: calll 0x1f1e ; puts
0x1ee9: calll 0x1f0c ; getchar
0x1eee: movl $20, (%esp)
0x1ef5: calll 0x1e6a ; sleep_loop at test.c:6
0x1efa: movl $12, %eax
0x1eff: addl $20, %esp
0x1f02: popl %ebx
0x1f03: leave
0x1f04: ret

This can be handy when dealing with the new --line options that was recently
added:

(lldb) disassemble --line
a.out`main + 13 at test.c:19
18 {
-> 19 printf("Process: %i\n\n", getpid());
20 puts("Press any key to continue..."); getchar();
-> 0x1ec4: calll 0x1f12 ; getpid
0x1ec9: movl %eax, 4(%esp)
0x1ecd: leal 199(%ebx), %eax
0x1ed3: movl %eax, (%esp)
0x1ed6: calll 0x1f18 ; printf

Modified the ModuleList to have a lookup based solely on a UUID. Since the
UUID is typically the MD5 checksum of a binary image, there is no need
to give the path and architecture when searching for a pre-existing
image in an image list.

Now that we support remote debugging a bit better, our lldb_private::Module
needs to be able to track what the original path for file was as the platform
knows it, as well as where the file is locally. The module has the two
following functions to retrieve both paths:

const FileSpec &Module::GetFileSpec () const;
const FileSpec &Module::GetPlatformFileSpec () const;

Added more platform support. There are now some new commands:

platform status -- gets status information for the selected platform
platform create <platform-name> -- creates a new instance of a remote platform
platform list -- list all available platforms
platform select -- select a platform instance as the current platform (not working yet)

When using "platform create" it will create a remote platform and make it the
selected platform. For instances for iPhone OS debugging on Mac OS X one can
do:

(lldb) platform create remote-ios --sdk-version=4.0
Remote platform: iOS platform
SDK version: 4.0
SDK path: "/Developer/Platforms/iPhoneOS.platform/DeviceSupport/4.0"
Not connected to a remote device.
(lldb) file ~/Documents/a.out
Current executable set to '~/Documents/a.out' (armv6).
(lldb) image list
[ 0] /Volumes/work/gclayton/Documents/devb/attach/a.out
[ 1] /Developer/Platforms/iPhoneOS.platform/DeviceSupport/4.0/Symbols/usr/lib/dyld
[ 2] /Developer/Platforms/iPhoneOS.platform/DeviceSupport/4.0/Symbols/usr/lib/libSystem.B.dylib


Note that this is all happening prior to running _or_ connecting to a remote
platform. Once connected to a remote platform the OS version might change which
means we will need to update our dependecies. Also once we run, we will need
to match up the actualy binaries with the actualy UUID's to files in the
SDK, or download and cache them locally.

This is just the start of the remote platforms, but this modification is the
first iteration in getting the platforms really doing something.

LLDB now has "Platform" plug-ins. Platform plug-ins are plug-ins that provide
an interface to a local or remote debugging platform. By default each host OS
that supports LLDB should be registering a "default" platform that will be
used unless a new platform is selected. Platforms are responsible for things
such as:
- getting process information by name or by processs ID
- finding platform files. This is useful for remote debugging where there is
an SDK with files that might already or need to be cached for debug access.
- getting a list of platform supported architectures in the exact order they
should be selected. This helps the native x86 platform on MacOSX select the
correct x86_64/i386 slice from universal binaries.
- Connect to remote platforms for remote debugging
- Resolving an executable including finding an executable inside platform
specific bundles (macosx uses .app bundles that contain files) and also
selecting the appropriate slice of universal files for a given platform.

So by default there is always a local platform, but remote platforms can be
connected to. I will soon be adding a new "platform" command that will support
the following commands:
(lldb) platform connect --name machine1 macosx connect://host:port
Connected to "machine1" platform.
(lldb) platform disconnect macosx

This allows LLDB to be well setup to do remote debugging and also once
connected process listing and finding for things like:
(lldb) process attach --name x<TAB>

The currently selected platform plug-in can now auto complete any available
processes that start with "x". The responsibilities for the platform plug-in
will soon grow and expand.

Fixed CommandReturnObject::SetImmediateErrorFile() to set the correct stream.

Modifed lldb_private::Process to be able to handle connecting to a remote
target that isn't running a process. This leaves lldb_private::Process in the
eStateConnected state from which we can then do an attach or launch.

Modified ProcessGDBRemote to be able to set stdin, stdout, stderr, working
dir, disable ASLR and a few other settings down by using new GDB remote
packets. This allows us to keep all of our current launch flags and settings
intact and still be able to communicate them over to the remote GDB server.
Previously these were being sent as arguments to the debugserver binary that
we were spawning. Also modified ProcessGDBRemote to handle losing connection
to the remote GDB server and always exit immediately. We do this by watching
the lldb_private::Communication event bit for the read thread exiting in the
ProcessGDBRemote async thread.

Added support for many of the new 'Q' packets for setting stdin, stdout,
stderr, working dir and disable ASLR to the GDBRemoteCommunication class for
easy accesss.

Modified debugserver for all of the new 'Q' packets and also made it so that
debugserver always exists if it loses connection with the remote debugger.

Abtracted all mach-o and ELF out of ArchSpec. This patch is a modified form
of Stephen Wilson's idea (thanks for the input Stephen!). What I ended up
doing was:
- Got rid of ArchSpec::CPU (which was a generic CPU enumeration that mimics
the contents of llvm::Triple::ArchType). We now rely upon the llvm::Triple
to give us the machine type from llvm::Triple::ArchType.
- There is a new ArchSpec::Core definition which further qualifies the CPU
core we are dealing with into a single enumeration. If you need support for
a new Core and want to debug it in LLDB, it must be added to this list. In
the future we can allow for dynamic core registration, but for now it is
hard coded.
- The ArchSpec can now be initialized with a llvm::Triple or with a C string
that represents the triple (it can just be an arch still like "i386").
- The ArchSpec can still initialize itself with a architecture type -- mach-o
with cpu type and subtype, or ELF with e_machine + e_flags -- and this will
then get translated into the internal llvm::Triple::ArchSpec + ArchSpec::Core.
The mach-o cpu type and subtype can be accessed using the getter functions:

uint32_t
ArchSpec::GetMachOCPUType () const;

uint32_t
ArchSpec::GetMachOCPUSubType () const;

But these functions are just converting out internal llvm::Triple::ArchSpec
+ ArchSpec::Core back into mach-o. Same goes for ELF.

All code has been updated to deal with the changes.

This should abstract us until later when the llvm::TargetSpec stuff gets
finalized and we can then adopt it.

- Changed all the places where CommandObjectReturn was exporting a StreamString to just exporting
a Stream, and then added GetOutputData & GetErrorData to get the accumulated data.
- Added a StreamTee that will tee output to two provided lldb::StreamSP's.
- Made the CommandObjectReturn use this so you can Tee the results immediately to
the debuggers output file, as well as saving up the results to return when the command
is done executing.
- HandleCommands now uses this so that if you have a set of commands that continue the target
you will see the commands come out as they are processed.
- The Driver now uses this to output the command results as you go, which makes the interface
more reactive seeming.

Made lldb_private::ArchSpec contain much more than just an architecture. It
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.

Added support for attaching to a remote debug server with the new command:
(lldb) process connect <remote-url>

Currently when you specify a file with the file command it helps us to find
a process plug-in that is suitable for debugging. If you specify a file you
can rely upon this to find the correct debugger plug-in:

% lldb a.out
Current executable set to 'a.out' (x86_64).
(lldb) process connect connect://localhost:2345
...

If you don't specify a file, you will need to specify the plug-in name that
you wish to use:

% lldb
(lldb) process connect --plugin process.gdb-remote connect://localhost:2345

Other connection URL examples:

(lldb) process connect connect://localhost:2345
(lldb) process connect tcp://127.0.0.1
(lldb) process connect file:///dev/ttyS1

We are currently treating the "connect://host:port" as a way to do raw socket
connections. If there is a URL for this already, please let me know and we
will adopt it.

So now you can connect to a remote debug server with the ProcessGDBRemote
plug-in. After connection, it will ask for the pid info using the "qC" packet
and if it responds with a valid process ID, it will be equivalent to attaching.
If it response with an error or invalid process ID, the LLDB process will be
in a new state: eStateConnected. This allows us to then download a program or
specify the program to run (using the 'A' packet), or specify a process to
attach to (using the "vAttach" packets), or query info about the processes
that might be available.

# 7fb56d0a 01-Feb-2011 Greg Clayton <gclayton@apple.com>

Endian patch from Kirk Beitz that allows better cross platform building.

llvm-svn: 124643


# 513c26ce 29-Jan-2011 Greg Clayton <gclayton@apple.com>

Finished up the async attach support. This allows us to request to attach
by name or by pid (with or without waiting for a process to launch) and
catch the response asynchronously.
