Get debugserver to call task_set_state to prime the control registers so that watchpoints
take for threads created while the program is running. Remove the testcase skips from TestConcurrentEvents.py,
since they all pass now, and fix TestWatchpointMultipleThreads.py - which should have caught this problem -
so it doesn't artificially break on new thread creation before the watchpoint triggers.

Remove some unnecessary uses of nub_break_t in the arm specific
support files for debugserver to fix a build failure for arm. Also
remove some of the code used for software-driven single instruction
stepping; this is slowly being yanked out and these particular bits
overlap with the nub_break_t going away.

Huge performance improvements when one breakpoint contains many locations.
325,000 breakpoints for running "breakpoint set --func-regex ." on lldb itself (after hitting a breakpoint at main so that LLDB.framework is loaded) used to take up to an hour to set, now we are down under a minute. With warm file caches, we are at 40 seconds, and that is with setting 325,000 breakpoint through the GDB remote API. Linux and the native debuggers might be faster. I haven't timed what how much is debug info parsing and how much is the protocol traffic to/from GDB remote.
That there were many performance issues. Most of them were due to storing breakpoints in the wrong data structures, or using the wrong iterators to traverse the lists, traversing the lists in inefficient ways, and not optimizing certain function name lookups/symbol merges correctly.
Debugging after that is also now very efficient. There were issues with replacing the breakpoint opcodes in memory that was read, and those routines were also fixed.

After discussing with Chris Lattner, we require C++11, so lets get rid of the macros and just use C++11.

Since we use C++11, we should switch over to using std::unique_ptr when C++11 is being used. To do this, we follow what we have done for shared pointers and we define a STD_UNIQUE_PTR macro that can be used and it will "do the right thing". Due to some API differences in std::unique_ptr and due to the fact that we need to be able to compile without C++11, we can't use move semantics so some code needed to change so that it can compile with either C++.
Anyone wanting to use a unique_ptr or auto_ptr should now use the "STD_UNIQUE_PTR(TYPE)" macro.

Add the new contains / invalidates mappings for the s, d, and q

Change the default format of s and d registers to be floating point
instead of hex. Remove some UTF-8 hyphen chars in comments in the ARM

Change debugserver from using the mach port number (in debugserver's
own port namepsace) as the thread identifier to using the system-wide
globally unique thread id as the thread identifier number.
MachThread.cpp keeps both the unique id and the mach port number
for each thread. All layers outside MachThread class use the unique
id with three exceptions: (1) Mach exceptions come in with the port
number (thread_port) which needs to be translated, (2) any calls to
low-level thread_get_state/thread_set_state/thread_suspend etc need
to use the mach port number, (3) MachThreadList::UpdateThreadList
which creates the MachThread objects gets the unique id and passes
it to the MachThread ctor as an argument.
In general, any time nub_thread_t is used, it is now referring to a
unique thread id. Any time a thread_t is used, it is now referring
to a mach port number. There was some interchangability of these
types previously. nub_thread_t has also been changed to a 64-bit
type which necessitated some printf specification string changes.
I haven't been able to test these changes extensively yet but want
to checkpoint the work. The scenarios I've been testing are all
working correctly so while there may be some corner cases I haven't
hit yet, I think it is substantially correct.

Fixed the 32, 16, and 8 bit pseudo regs for x86_64 (real reg of "rax" which subvalues "eax", "ax", etc...) to correctly get updated when stepping. Also fixed it so actual registers can specify what other registers must be invalidated when a register is modified. Previously, only pseudo registers could invalidate other registers.
Modified the LLDB qRegisterInfo extension to the GDB remote interface to support specifying the containing registers with the new "container-regs" key whose value is a comma separated list of register numbers. Also added a "invalidate-regs" key whose value is also a comma separated list of register numbers.
Removed the hack GDBRemoteDynamicRegisterInfo::Addx86_64ConvenienceRegisters() function and modified "debugserver" to specify the registers correctly using the new "container-regs" and "invalidate-regs" keys.

Add unconditional logging messages to every place in debugserver
where we send a SIGKILL signal or do a ptrace PT_KILL call to
terminate the inferior process. When the debuggee is silently
killed off, the console logging from debugserver can disambiguate
whether debugserver killed off the process because it failed to
completely set it up, becuase it was told to (via the "k" packet),
or if some external daemon killed it.

Previous check-ins allow to hit the arm hardware watchpoint, with a workaound to handle the issue
that the inferior cannot execute past the watchpoint-triggering instruction.
The solution is disable the watchpoint before resuming the inferior and make it hardware single step;
when the inferior stops again due to single step, re-enable the watchpoint and disable the single step
to make the inferior able to continue again without obstacle.

WIP snapshot of hardware watchpoints for arm. A simple watchpoint has triggered.
However, the debugserver cannot get past the instruction which triggered the watchpoint.
So a workaround is in place for the time being which disables the triggered watchpoint
before resuming.
Lots of commented out printf's remain in the source which needs to be cleaned up.

Always return a valid answer for qMemoryRegionInfo if the packet is supported.
We will return a valid range when possible and omit the "permissions" key
when the memory is not readable, writeable or executeable. This will help us
know the difference between an error back from this packet and unsupported,
from just "this address isn't in a valid region".

Added optional calls to lldb_private::Process for getting memory region info
from a process and hooked it up to the new packet that was recently added
to our GDB remote executable named debugserver. Now Process has the following
new calls:
virtual Error
Process::GetMemoryRegionInfo (lldb::addr_t load_addr, MemoryRegionInfo &range_info);
virtual uint32_t
GetLoadAddressPermissions (lldb::addr_t load_addr);
Only the first one needs to be implemented by subclasses that can add this
support.
Cleaned up the way the new packet was implemented in debugserver to be more
useful as an API inside debugserver. Also found an error where finding a region
for an address actually will pick up the next region that follows the address
in the query so we also need ot make sure that the address we requested the
region for falls into the region that gets returned.

Remove the QAddressIsExecutable packet I added last night.
Add a more general purpose qMemoryRegionInfo packet which can
describe various attributes about a memory region. Currently it
will return the start address, size, and permissions (read, write,
executable) for the memory region. It may be possible to add
additional attributes in the future such as whether the region is
designated as stack memory or jitted code a la vmmap.
I still haven't implemented the lldb side of the code to use this
packet yet so there may be unexpected behavior - but the basic implementation looks
about right. I'll hook it up to lldb soon and fix any problems that crop up.

Add "QAddressIsExecutable" packet to debugserver. Used to test
whether a given address is in an executable region of memory or
not. I haven't written the lldb side that will use this packet it
hasn't been tested yet but it's a simple enough bit of code.
I want to have this feature available for the unwinder code. When
we're stopped at an address with no valid symbol context, there are
a number of questions I'd like to ask --
is the current pc value in an executable region (e.g. did they
jump to unallocated/unexecutable memory? we know how to unwind
from here if so.)
Is the stack pointer or the frame pointer the correct register
to use to find the caller's saved pc value?
Once we're past the first frame we can trust things like eh_frame
and ABI unwind schemes but the first frame is challenging and having
a way to check potential addresses to see if they're executable or
not would help narrow down the possibilities a lot.

Fixed the Xcode project building of LLVM to be a bit more user friendly:
- If you download and build the sources in the Xcode project, x86_64 builds
by default using the "llvm.zip" checkpointed LLVM.
- If you delete the "lldb/llvm.zip" and the "lldb/llvm" folder, and build the
Xcode project will download the right LLVM sources and build them from
scratch
- If you have a "lldb/llvm" folder already that contains a "lldb/llvm/lib"
directory, we will use the sources you have placed in the LLDB directory.
Python can now be disabled for platforms that don't support it.
Changed the way the libllvmclang.a files get used. They now all get built into
arch specific directories and never get merged into universal binaries as this
was causing issues where you would have to go and delete the file if you wanted
to build an extra architecture slice.

Modify the delegation chain from MachThreadList -> MachThread -> DNBArchProtocol so that when
the watchpoint state is changed, not only does the change propagate to all the thread instances,
it also updates a global debug state, if chosen by the DNBArchProtocol derivative.
Once implemented, the DNBArchProtocol derivative, also makes sure that when new thread comes along,
it tries to inherit from the global debug state, if it is valid.
Modify TestWatchpointMultipleThreads.py to test this functionality.

we can easily convert any pointer to a shared pointer.

Add logic to the DNBArchImplX86_64/DNBArchImplI386::NotifyException() callback method
in order to distinguish the real single step exception from a watchpoint exception
which uses the same exc_type of EXC_BREAKPOINT and exc_code of EXC_I386_SGL.
This is done by checking the debug status register to find out whether the watchpoint
data break event has fired, and, if yes, stuff the data break address into the exception's
exc_sub_code field on the debugserver side for lldb to consume on the other end.

Added support for dynamic detection of AVX, and
fixed a few bugs that revealed. Now the "register
read" command should show AVX registers
(ymm0-ymm15) on Mac OS X platforms that support
them.
When testing this on Mac OS X, run debugserver
manually, like this:
debugserver --native-regs localhost:1111 /path/to/executable
Then
lldb /path/to/executable
...

Added the ability to see block variables when looking up addresses
with the "target modules lookup --address <addr>" command. The variable
ID's, names, types, location for the address, and declaration is
displayed.
This can really help with crash logs since we get, on MacOSX at least,
the registers for the thread that crashed so it is often possible to
figure out some of the variable contents.

Fixed an issue in the EmulateInstructionARM there the IT opcode was trying to
parse NOP instructions. I added the new table entries for the NOP for the
plain NOP, Yield, WFE, WFI, and SEV variants. Modified the opcode emulation
function EmulateInstructionARM::EmulateMOVRdSP(...) to notify us when it is
creating a frame. Also added an abtract way to detect the frame pointer
register for both the standard ARM ABI and for Darwin.
Fixed GDBRemoteRegisterContext::WriteAllRegisterValues(...) to correctly be
able to individually write register values back if case the 'G' packet is
not implemented or returns an error.
Modified the StopInfoMachException to "trace" stop reasons. On ARM we currently
use the BVR/BCR register pairs to say "stop when the PC is not equal to the
current PC value", and this results in a EXC_BREAKPOINT mach exception that
has 0x102 in the code.
Modified debugserver to create the short option string from long option
definitions to make sure it doesn't get out of date. The short option string
was missing many of the newer short option values due to a modification of
the long options defs, and not modifying the short option string.

Added new lldb_private::Process memory read/write functions to stop a bunch
of duplicated code from appearing all over LLDB:
lldb::addr_t
Process::ReadPointerFromMemory (lldb::addr_t vm_addr, Error &error);
bool
Process::WritePointerToMemory (lldb::addr_t vm_addr, lldb::addr_t ptr_value, Error &error);
size_t
Process::ReadScalarIntegerFromMemory (lldb::addr_t addr, uint32_t byte_size, bool is_signed, Scalar &scalar, Error &error);
size_t
Process::WriteScalarToMemory (lldb::addr_t vm_addr, const Scalar &scalar, uint32_t size, Error &error);
in lldb_private::Process the following functions were renamed:
From:
uint64_t
Process::ReadUnsignedInteger (lldb::addr_t load_addr,
size_t byte_size,
Error &error);
To:
uint64_t
Process::ReadUnsignedIntegerFromMemory (lldb::addr_t load_addr,
size_t byte_size,
uint64_t fail_value,
Error &error);
Cleaned up a lot of code that was manually doing what the above functions do
to use the functions listed above.
Added the ability to get a scalar value as a buffer that can be written down
to a process (byte swapping the Scalar value if needed):
uint32_t
Scalar::GetAsMemoryData (void *dst,
uint32_t dst_len,
lldb::ByteOrder dst_byte_order,
Error &error) const;
The "dst_len" can be smaller that the size of the scalar and the least
significant bytes will be written. "dst_len" can also be larger and the
most significant bytes will be padded with zeroes.
Centralized the code that adds or removes address bits for callable and opcode
addresses into lldb_private::Target:
lldb::addr_t
Target::GetCallableLoadAddress (lldb::addr_t load_addr, AddressClass addr_class) const;
lldb::addr_t
Target::GetOpcodeLoadAddress (lldb::addr_t load_addr, AddressClass addr_class) const;
All necessary lldb_private::Address functions now use the target versions so
changes should only need to happen in one place if anything needs updating.
Fixed up a lot of places that were calling :
addr_t
Address::GetLoadAddress(Target*);
to call the Address::GetCallableLoadAddress() or Address::GetOpcodeLoadAddress()
as needed. There were many places in the breakpoint code where things could
go wrong for ARM if these weren't used.

Added functions to lldb_private::Address to set an address from a load address
and set the address as an opcode address or as a callable address. This is
needed in various places in the thread plans to make sure that addresses that
might be found in symbols or runtime might already have extra bits set (ARM/Thumb).
The new functions are:
bool
Address::SetCallableLoadAddress (lldb::addr_t load_addr, Target *target);
bool
Address::SetOpcodeLoadAddress (lldb::addr_t load_addr, Target *target);
SetCallableLoadAddress will initialize a section offset address if it can,
and if so it might possibly set some bits in the address to make the address
callable (bit zero might get set for ARM for Thumb functions).
SetOpcodeLoadAddress will initialize a section offset address using the
specified target and it will strip any special address bits if needed
depending on the target.
Fixed the ABIMacOSX_arm::GetArgumentValues() function to require arguments
1-4 to be in the needed registers (previously this would incorrectly fallback
to the stack) and return false if unable to get the register values. The
function was also modified to first look for the generic argument registers
and then fall back to finding the registers by name.
Fixed the objective trampoline handler to use the new Address::SetOpcodeLoadAddress
function when needed to avoid address mismatches when trying to complete
steps into objective C methods. Make similar fixes inside the
AppleThreadPlanStepThroughObjCTrampoline::ShouldStop() function.
Modified ProcessGDBRemote::BuildDynamicRegisterInfo(...) to be able to deal with
the new generic argument registers.
Modified RNBRemote::HandlePacket_qRegisterInfo() to handle the new generic
argument registers on the debugserver side.
Modified DNBArchMachARM::NumSupportedHardwareBreakpoints() to be able to
detect how many hardware breakpoint registers there are using a darwin sysctl.
Did the same for hardware watchpoints in
DNBArchMachARM::NumSupportedHardwareWatchpoints().

Added generic register numbers for simple ABI argument registers and defined
the appropriate registers for arm and x86_64. The register names for the
arguments that are the size of a pointer or less are all named "arg1", "arg2",
etc. This allows you to read these registers by name:
(lldb) register read arg1 arg2 arg3
...
You can also now specify you want to see alternate register names when executing
the read register command:
(lldb) register read --alternate
(lldb) register read -A

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".

(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.

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.

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

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;

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.

Added a new variant of SBTarget::Launch() that deprectates the old one that
takes separate file handles for stdin, stdout, and stder and also allows for
the working directory to be specified.
Added support to "process launch" to a new option: --working-dir=PATH. We
can now set the working directory. If this is not set, it defaults to that
of the process that has LLDB loaded. Added the working directory to the
host LaunchInNewTerminal function to allows the current working directory
to be set in processes that are spawned in their own terminal. Also hooked this
up to the lldb_private::Process and all mac plug-ins. The linux plug-in had its
API changed, but nothing is making use of it yet. Modfied "debugserver" and
"darwin-debug" to also handle the current working directory options and modified
the code in LLDB that spawns these tools to pass the info along.
Fixed ProcessGDBRemote to properly pass along all file handles for stdin, stdout
and stderr.
After clearing the default values for the stdin/out/err file handles for
process to be NULL, we had a crasher in UserSettingsController::UpdateStringVariable
which is now fixed. Also fixed the setting of boolean values to be able to
be set as "true", "yes", "on", "1" for true (case insensitive) and "false", "no",
"off", or "0" for false.
Fixed debugserver to properly handle files for STDIN, STDOUT and STDERR that are not
already opened. Previous to this fix debugserver would only correctly open and dupe
file handles for the slave side of a pseudo terminal. It now correctly handles
getting STDIN for the inferior from a file, and spitting STDOUT and STDERR out to
files. Also made sure the file handles were correctly opened with the NOCTTY flag
for terminals.

Fixed the GDB remote plug-in to once again watch for a reply from the "k"
packet, and fixed the logic to make sure the thread requesting the kill
and the async thread play nice (and very quickly) by synchronizing the
packet sending and reply. I also tweaked some of the shut down packet
("k" kill, "D" detach, and the halt packet) to make sure they do the right
thing.
Fixed "StateType Process::WaitForProcessStopPrivate (...)" to correctly pass
the timeout along to WaitForStateChangedEventsPrivate() and made the function
behave correctly with respect to timing out.
Added separate STDIN, STDOUT, and STDERR support to debugserver. Also added
the start of being able to set the working directory for the inferior process.

Thread safety changes in debugserver and also in the process GDB remote plugin.
I added support for asking if the GDB remote server supports thread suffixes
for packets that should be thread specific (register read/write packets) because
the way the GDB remote protocol does it right now is to have a notion of a
current thread for register and memory reads/writes (set via the "$Hg%x" packet)
and a current thread for running ("$Hc%x"). Now we ask the remote GDB server
if it supports adding the thread ID to the register packets and we enable
that feature in LLDB if supported. This stops us from having to send a bunch
of packets that update the current thread ID to some value which is prone to
error, or extra packets.

Add '-no-stdio' option to 'process launch' command, which causes the
inferior to be launched without setting up terminal stdin/stdout for it
(leaving the lldb command line accessible while the program is executing).
Also add a user settings variable, 'target.process.disable-stdio' to allow
the user to set this globally rather than having to use the command option
each time the process is launched.

Fixed Process::Halt() as it was broken for "process halt" after recent changes
to the DoHalt down in ProcessGDBRemote. I also moved the functionality that
was in ProcessGDBRemote::DoHalt up into Process::Halt so not every class has
to implement a tricky halt/resume on the internal state thread. The
functionality is the same as it was before with two changes:
- when we eat the event we now just reuse the event we consume when the private
state thread is paused and set the interrupted bool on the event if needed
- we also properly update the Process::m_public_state with the state of the
event we consume.
Prior to this, if you issued a "process halt" it would eat the event, not
update the process state, and then produce a new event with the interrupted
bit set and send it. Anyone listening to the event would get the stopped event
with a process that whose state was set to "running".
Fixed debugserver to not have to be spawned with the architecture of the
inferior process. This worked fine for launching processes, but when attaching
to processes by name or pid without a file in lldb, it would fail.
Now debugserver can support multiple architectures for a native debug session
on the current host. This currently means i386 and x86_64 are supported in
the same binary and a x86_64 debugserver can attach to a i386 executable.
This change involved a lot of changes to make sure we dynamically detect the
correct registers for the inferior process.

thread basic info state and not realize that a thread was already suspended
or if a thread was starting up and not ready to be displayed to the user
(in an uninterruptable state). If it is not user ready yet, we don't add it
to our list of threads that can be played with.

If debugserver is running on the local machine, pass it a
pseudoterminal to pass to the inferior for the inferior's I/O
(to allow direct writing, rather than passing all the I/O around
via packets).

Fix problem where "process detach" was not working properly. The
ptrace thread update that was replying to the SIGSTOP was also causing the
process to not really be sigstop'd any more so then the call to ptrace
detach was failing, and when debugserver exited the attached process
was being killed. Now the ptrace thread update does not disturb the sigstop
state of the thread, so the detach works properly.

Still trying to get detach to work with debugserver. Got a bit closer,
but something is still killing our inferior.
Fixed an issue with darwin-debug where it wasn't passing all needed arguments
to the inferior.
Fixed a race condition with the attach to named process code.

Fixed an issue with MachTask::TaskResume () where if the task was already
suspended, we would call "int ::task_resume (task_t task);" as many times as
it took to resume the task which isn't what we want to do.

Another patch from Jean-Daniel. Thanks.
Error in dbg server -> MachProcess::SetProcessID() and misc changes to make clang++ happy.

Got the ARM version of debugserver up to date.
Renamed the "dispatchqaddr" setting that was coming back for stop reply packets
to be named "qaddr" so that gdb doesn't thing it is a register number. gdb
was checking the first character and assuming "di" was a hex register number
because 'd' is a hex digit. It has been shortened so gdb can safely ignore it.

Added the ability to disable ASLR (Address Space Layout Randomization). ASLR
is disabled by default, and can be enabled using:
(lldb) set disable-aslr 0

Fixed debugserver to not exit when we are able to spawn the process, yet not
launch it due to not being able to get the task port. A SIGHUP was killing us
and also an error string wasn't properly being passed along. Got rid of a
class error variable that can only lead to multi-threaded crashes.

More leaks detection:
- fixed 3 posix spawn attributes leaks
- fixed us always leaking CXXBaseSpecifier objects when we create class
base classes. Clang apparently copies the base classes we pass in.
Fixed some code formatting in ClangASTContext.cpp.
