If debugserver fails to interrogate the inferior process CPU type
for any reason, use debugserver own's cputype as a best guess when
we reply to the debugger's qProcessInfo packet or when initializing
our register tables.

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.

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

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.

cpu type, cpu subtype, OS and vendor information just like qHostInfo
does so lldb can create an ArchSpec based on the returned values.
Add a new GetProcessArchitecture to GDBRemoteCommunicationClient akin
to GetHostArchitecture. If the qProcessInfo packet is supported,
GetProcessArchitecture will return the cpu type / subtype of the
process -- e.g. a 32-bit user process running on a 64-bit x86_64 Mac
system.
Have ProcessGDBRemote set the Target's architecture based on the

It increases performance if enabled (the reply to the "QListThreadsInStopReply" is "OK") by saving us from sending to command/reply pairs (the "qfThreadInfo" and "qsThreadInfo" packets), and also helps us keep the current process state up to date.

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.

Add logic to MachThreadList::GetThreadID() for the use case of setting a watchpoint
(MachThreadList::EnableHardwareWatchpoint()) where the watchpoint is not associated
with a thread and the current thread, if set, is returned, otherwise we return the
first thread.

the validity of break_id/watch_id.

RNBRemote.cpp, RNBRemote.h: Add a new qGetPid packet which returns
the pid of the process currently being debugged by debugserer in
hex, or 0 if unavailable.
This is effectively the same as the qC packet but that packet is
not clear in either its documentation or implementation (in gdb et al)
as to whether it is intended to return a pid or a thread id. qGetPid
is unambiguous.
If qGetPid is unimplemented in the remote debugserver, the debugger may
try qC and see what kind of value is returned..

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 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().

Fixed not being able to launch the i386 slice of a universal binary by adding

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.

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;

Abtracted the innards of lldb-core away from the SB interface. There was some
overlap in the SWIG integration which has now been fixed by introducing
callbacks for initializing SWIG for each language (python only right now).
There was also a breakpoint command callback that called into SWIG which has
been abtracted into a callback to avoid cross over as well.
Added a new binary: lldb-platform
This will be the start of the remote platform that will use as much of the
Host functionality to do its job so it should just work on all platforms.
It is pretty hollowed out for now, but soon it will implement a platform
using the GDB remote packets as the transport.

Split all of the core of LLDB.framework/lldb.so into a
static archive that can be linked against. LLDB.framework/lldb.so
exports a very controlled API. Splitting the API into a static
library allows other tools (debugserver for now) to use the power
of the LLDB debugger core, yet not export it as its API is not
portable or maintainable. The Host layer and many of the other
internal only APIs can now be statically linked against.
Now LLDB.framework/lldb.so links against "liblldb-core.a" instead
of compiling the .o files only for the shared library. This fix
is only for compiling with Xcode as the Makefile based build already
does this.
The Xcode projecdt compiler has been changed to LLVM. Anyone using
Xcode 3 will need to manually change the compiler back to GCC 4.2,
or update to Xcode 4.

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.

The DynamicLoader plug-in instance now lives up in lldb_private::Process where
it should live and the lldb_private::Process takes care of managing the
auto pointer to the dynamic loader instance.
Also, now that the ArchSpec contains the target triple, we are able to
correctly set the Target architecture in DidLaunch/DidAttach in the subclasses,
and then the lldb_private::Process will find the dynamic loader plug-in
by letting the dynamic loader plug-ins inspect the arch/triple in the target.
So now the ProcessGDBRemote plug-in is another step closer to be purely
process/platform agnostic.
I updated the ProcessMacOSX and the ProcessLinux plug-ins accordingly.

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

Finally tracked down the racy condition that would hose up our debug
sessions: When continue packet has been sent and an interrupt packet was
quickly sent, it would get read at the same time:
$c#00\x03
There was an error where the packet end index was always being computed
incorrectly by debugserver, but it wouldn't matter if there weren't extra
bytes on the end (the hex \x03 interrupt byte in this case). The first
'$' last 3 bytes of the data in the packet buffer were being trimmed
(trying to trim the '#' + checksum (#XX)) which made:
c#
And this would then be passed to the handle routine for the 'c' packet which
would see an extra character at the end and assume it was going to be in the
form c[addr] where "[addr]" was a hex address to resume at and this would
result in a malformed packet response. This is now fixed and everything works
great.
Another issue was issuing async packets correctly by doing correct handshakes
between the thread that wants to send the async packet, and the thread that
is tracking the current run.
Added a write lock to the communication class as well to make sure you never
get two threads trying to write data at the same time. This wasn't happening,
but it is a good idea to make sure it doesn't.

Fixed an issue in "SBError SBProcess::Destroy ()" where it wasn't properly
checking the validity of the shared pointer prior to using it.
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.

Sped up the shutdown time on MacOSX by quite a bit by making sure any
threads that we spawn let us know when they are going away and that we
don't timeout waiting for a message from threads that have gone away.
We also now don't expect the "k" packet (kill) to send a response. This
greatly speeds up debugger shutdown performance. The test suite now runs
quite a bit faster.
Added a fix to the variable display code that fixes the display of
base classes. We were assuming the virtual or normal base class offsets
were being given in bit sizes, but they were being given as character
sizes, so we needed to multiply the offset by 8. This wasn't affecting
the expression parser, but it was affecting the correct display of C++
class base classes and all of their children.

Took the timeout for a ClangUserExpression down from a 10 second timeout to
500 ms.
Make MachThreadList more threadsafe.
Added code to make sure the thread register state was properly flushed for x86_64.
Fixed an missing return code for the current thread in the new thread suffix code.
Improved debugserver logging.

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.

Modified the stop reply packet to be able to send the thread name using the
new "hexname" key for the "key:value;" duple that is part of the packet. This
allows for thread names to contain special characters such as $ # : ; + -
Debugserver now detects if the thread name contains special characters and
sends the chars in hex format if needed.

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.

Still trying to get detach to work with debugserver. Got a bit closer,
but something is still killing our inferior.

to the inferior.

Fixed debugserver to properly attach to a process by name with the
"vAttachName;<PROCNAME>" packet, and wait for a new process by name to launch
with the "vAttachWait;<PROCNAME>".
Fixed a few issues with attaching where if DoAttach() returned no error, yet
there was no valid process ID, we would deadlock waiting for an event that
would never happen.
Added a new "process launch" option "--tty" that will launch the process
in a new terminal if the Host layer supports the "Host::LaunchInNewTerminal(...)"
function. This currently works on MacOSX and will allow the debugging of
terminal applications that do complex operations with the terminal.
Cleaned up the output when the process resumes, stops and halts to be
consistent with the output format.

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.
