set by default when dumping registers. If you want to see all of the register
sets you can use the "--all" option:

(lldb) register read --all

If you want to just see some register sets, you can currently specify them
by index:

(lldb) register read --set 0 --set 2

We need to get shorter register set names soon so we can specify the register
sets by name without having to type too much. I will make this change soon.

You can also have any integer encoded registers resolve the address values
back to any code or data from the object files using the "--lookup" option.
Below is sample output when stopped in the libc function "puts" with some
const strings in registers:

Process 8973 stopped

As we can see, we see two constant strings and the PC (register "rip") is 
showing the code it resolves to.

I fixed the register "--format" option to work as expected.

Added a setting to disable skipping the function prologue when setting 
breakpoints as a target settings variable:

(lldb) settings set target.skip-prologue false

Updated the user settings controller boolean value handler funciton to be able
to take the default value so it can correctly respond to the eVarSetOperationClear
operation.

Did some usability work on the OptionValue classes.

Fixed the "image lookup" command to correctly respond to the "--verbose" 
option and display the detailed symbol context information when looking up
line table entries and functions by name. This previously was only working
for address lookups.

Add the infrastructure to test instruction emulations automatically.
The idea is that the instruction to be emulated is actually executed
on the hardware to be emulated, with the before and after state of the
hardware being captured and 'freeze-dried' into .dat files.  The
emulation testing code then loads the before & after state from the
.dat file, emulates the instruction using the before state, and
compares the resulting state to the 'after' state.  If they match, the
emulation is accurate, otherwise there is a problem.

The final format of the .dat files needs a bit more work; the plan is
to generalize them a bit and to convert the plain values to key-value pairs. 
But I wanted to get this first pass committed.

This commit adds arm instruction emulation testing to the testsuite, along with
many initial .dat files.

It also fixes a bug in the llvm disassembler, where 32-bit thumb opcodes
were getting their upper & lower 16-bits reversed.

There is a new Instruction sub-class, that is intended to be loaded
from a .dat file rather than read from an executable.  There is also a
new EmulationStateARM class, for handling the before & after states.
EmulationStates for other architetures can be added later when we
emulate their instructions.

llvm-svn: 129832

places that were dumping values for the settings. Centralized all of the
value dumping into a single place. When dumping values that aren't strings
we no longer surround the value with single quotes. When dumping values that
are strings, surround the string value with double quotes. When dumping array
values, assume they are always string values, and don't put quotes around
dictionary values.

llvm-svn: 129826

line tables specify breakpoints can be set in the source. When dumping the
source, the number of breakpoints that can be set on a source line are shown
as a prefix:

(lldb) source list -f test.c -l1 -c222 -b
       1   	#include <stdio.h>
       2   	#include <sys/fcntl.h>
       3   	#include <unistd.h>
       4   	int
       5   	sleep_loop (const int num_secs)
[2]    6   	{
       7   	    int i;
[1]    8   	    for (i=0; i<num_secs; ++i)
       9   	    {
[1]    10  	        printf("%d of %i - sleep(1);\n", i, num_secs);
[1]    11  	        sleep(1);       
       12  	    }
       13  	    return 0;
[1]    14  	}
       15  	
       16  	int 
       17  	main (int argc, char const* argv[])
[1]    18  	{
[1]    19  	    printf("Process: %i\n\n", getpid());
[1]    20  	    puts("Press any key to continue..."); getchar();
[1]    21  	    sleep_loop (20);
       22  	    return 12;
[1]    23  	}

Above we can see there are two breakpoints for line 6 and one breakpoint for
lines 8, 10, 11, 14, 18, 19, 20, 21 and 23. All other lines have no line table
entries for them. This helps visualize the data provided in the debug 
information without having to manually dump all line tables. It also includes
all inline breakpoint that may result for a given file which can also be very
handy to see.

llvm-svn: 129747

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.

Add support for "dynamic values" for C++ classes.  This currently only works for "frame var" and for the
expressions that are simple enough to get passed to the "frame var" underpinnings.  The parser code will
have to be changed to also query for the dynamic types & offsets as it is looking up variables.

The behavior of "frame var" is controlled in two ways.  You can pass "-d {true/false} to the frame var
command to get the dynamic or static value of the variables you are printing.

There's also a general setting:

target.prefer-dynamic-value (boolean) = 'true'

which is consulted if you call "frame var" without supplying a value for the -d option.

llvm-svn: 129623

Modified the OptionGroupOptions to be able to specify only some of the options
that should be appended by using the usage_mask in the group defintions and
also provided a way to remap them to a new usage mask after the copy. This 
allows options to be re-used and also targetted for specific option groups.

Modfied the CommandArgumentType to have a new eArgTypePlatform enumeration.
Taught the option parser to be able to automatically use the appropriate
auto completion for a given options if nothing is explicitly specified
in the option definition. So you don't have to specify it in the option
definition tables.

Renamed the default host platform name to "host", and the default platform
hostname to be "localhost".

Modified the "file" and "platform select" commands to make sure all options
and args are good prior to creating a new platform. Also defer the computation
of the architecture in the file command until all options are parsed and the
platform has either not been specified or reset to a new value to avoid
computing the arch more than once.

Switch the PluginManager code over to using llvm::StringRef for string
comparisons and got rid of all the AccessorXXX functions in lieu of the newer
mutex + collection singleton accessors.

llvm-svn: 129483

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.

Fix various things in the instruction emulation code:

    - Add ability to control whether or not the emulator advances the
    PC register (in the emulation state), if the instruction itself
    does not change the pc value..

    - Fix a few typos in asm description strings.

    - Fix bug in the carry flag calculation.

Something changed in commit r129112 where a few standard headers vanished from
the include chain when building on Linux.  Fix up by including limits.h for
INT_MAX and PATH_MAX where needed, and stdio.h for printf().

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.

GDBRemoteCommunicationServer classes. This involved adding a new packet
named "qSpeedTest" which can test the speed of a packet send/response pairs
using a wide variety of send/recv packet sizes.

Added a few new connection classes: one for shared memory, and one for using
mach messages (Apple only). The mach message stuff is experimental and not 
working yet, but added so I don't lose the code. The shared memory stuff
uses pretty standard calls to setup shared memory.

Modified the ProcessInfo structure to contain all process arguments. Using the
new function calls on MacOSX allows us to see the full process name, not just
the first 16 characters.

that can be used to get detailed information for a process including all 
arguments, user and group info and more.

const data, etc, and also for SBAddress objects to classify their type of
section they are in and also getting the module for a section offset address.

Convert ValueObject to explicitly maintain the Execution Context in which they were created, and then use that when they update themselves.  That means all the ValueObject evaluate me type functions that used to require a Frame object now do not.  I didn't remove the SBValue API's that take this now useless frame, but I added ones that don't require the frame, and marked the SBFrame taking ones as deprecated.

llvm-svn: 128593

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 
PID    PARENT USER       GROUP      EFF USER   EFF GROUP  TRIPLE                   NAME

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;

llvm-svn: 128563

an architecture into ArchSpec:

uint32_t
ArchSpec::GetMinimumOpcodeByteSize() const;

uint32_t
ArchSpec::GetMaximumOpcodeByteSize() const;

Added an AddressClass to the Instruction class in Disassembler.h.
This allows decoded instructions to know know if they are code,
code with alternate ISA (thumb), or even data which can be mixed
into code. The instruction does have an address, but it is a good
idea to cache this value so we don't have to look it up more than 
once.

Fixed an issue in Opcode::SetOpcodeBytes() where the length wasn't
getting set.

Changed:

	bool
	SymbolContextList::AppendIfUnique (const SymbolContext& sc);

To:
	bool
	SymbolContextList::AppendIfUnique (const SymbolContext& sc, 
									   bool merge_symbol_into_function);

This function was typically being used when looking up functions
and symbols. Now if you lookup a function, then find the symbol,
they can be merged into the same symbol context and not cause
multiple symbol contexts to appear in a symbol context list that
describes the same function.

Fixed the SymbolContext not equal operator which was causing mixed
mode disassembly to not work ("disassembler --mixed --name main").

Modified the disassembler classes to know about the fact we know,
for a given architecture, what the min and max opcode byte sizes
are. The InstructionList class was modified to return the max
opcode byte size for all of the instructions in its list.
These two fixes means when disassemble a list of instructions and dump 
them and show the opcode bytes, we can format the output more 
intelligently when showing opcode bytes. This affects any architectures
that have varying opcode byte sizes (x86_64 and i386). Knowing the max
opcode byte size also helps us to be able to disassemble N instructions
without having to re-read data if we didn't read enough bytes.

Added the ability to set the architecture for the disassemble command.
This means you can easily cross disassemble data for any supported 
architecture. I also added the ability to specify "thumb" as an 
architecture so that we can force disassembly into thumb mode when
needed. In GDB this was done using a hack of specifying an odd
address when disassembling. I don't want to repeat this hack in LLDB,
so the auto detection between ARM and thumb is failing, just specify
thumb when disassembling:

(lldb) disassemble --arch thumb --name main

You can also have data in say an x86_64 file executable and disassemble
data as any other supported architecture:
% lldb a.out
Current executable set to 'a.out' (x86_64).
(lldb) b main
(lldb) run
(lldb) disassemble --arch thumb --count 2 --start-address 0x0000000100001080 --bytes
0x100001080:  0xb580 push   {r7, lr}
0x100001082:  0xaf00 add    r7, sp, #0

Fixed Target::ReadMemory(...) to be able to deal with Address argument object
that isn't section offset. When an address object was supplied that was
out on the heap or stack, target read memory would fail. Disassembly uses
Target::ReadMemory(...), and the example above where we disassembler thumb
opcodes in an x86 binary was failing do to this bug.

plugin by name on the command line for when there is more than one disassembler
plugin.

Taught the Opcode class to dump itself so that "disassembler -b" will dump
the bytes correctly for each opcode type. Modified all places that were passing
the opcode bytes buffer in so that the bytes could be displayed to just pass
in a bool that indicates if we should dump the opcode bytes since the opcode
now lives inside llvm_private::Instruction.

llvm-svn: 128290

Modified the Disassembler::Instruction base class to contain an Opcode 
instance so that we can know the bytes for an instruction without needing
to keep the data around.

Modified the DisassemblerLLVM's instruction class to correctly extract the
opcode bytes if all goes well.

public types and public enums. This was done to keep the SWIG stuff from
parsing all sorts of enums and types that weren't needed, and allows us to
abstract our API better.

On Mac OS X we now have 3 platforms:
PlatformDarwin - must be subclassed to fill in the missing pure virtual funcs
                 but this implements all the common functionality between
                 remote-macosx and remote-ios. It also allows for another
                 platform to be used (remote-gdb-server for now) when doing
                 remote connections. Keeping this pluggable will allow for
                 flexibility.
PlatformMacOSX - Now implements both local and remote macosx desktop platforms.
PlatformRemoteiOS - Remote only iOS that knows how to locate SDK files in the
                    cached SDK locations on the host.

A new agnostic platform has been created:
PlatformRemoteGDBServer - this implements the platform using the GDB remote 
                          protocol and uses the built in lldb_private::Host
                          static functions to implement many queries.

Add the ability to disassemble "n" instructions from the current PC, or the first "n" instructions in a function.
Also added a "-p" flag that disassembles from the current pc.

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.

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.

The UserSettings controllers must be initialized & terminated in the
correct order.  Previously this was tacitly implemented but not
enforced, so it was possible to accidentally do things in the wrong
order and cause problems.  This fixes that problem.

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.

The major issue this patch solves is that ArchSpec::SetTriple no longer depends
on the implementation of Host::GetArchitecture.  On linux, Host::GetArchitecture
calls ArchSpec::SetTriple, thus blowing the stack.

A second smaller point is that SetTriple now defaults to Host defined components
iff all OS, vendor and environment fields are not set.
