This is done by adding a "Variable *" to SymbolContext and allowing SymbolFile::ResolveSymbolContext() so if an address is resolved into a symbol context, we can include the global or static variable for that address.
This means you can now find global variables that are merged globals when doing a "image lookup --verbose --address 0x1230000". Previously we would resolve a symbol and show "_MergedGlobals123 + 1234". But now we can show the global variable name.

Also, keep the hit count for the breakpoint in the breakpoint. We were

The default help display now shows the alias collection by default, and hides commands whose named begin with an underscore. Help is primarily useful to those unfamiliar with LLDB and should aim to answer typical questions while still being able to provide more esoteric answers when required. To that latter end an argument to include the hidden commands in help has been added, and instead of having a help flag to show aliases there is now one to hide them. This final change might be controversial as it repurposes the -a shorthand as the opposite of its original meaning.
The previous implementation of OutputFormattedHelpText was easily confused by embedded newlines. The new algorithm correctly breaks on the FIRST newline or LAST space/tab before the target column count rather than treating all whitespace interchangeably.
Command interpreters now have the ability to specify help prologue text and a command prefix string. Neither are used in the current LLDB sources but are required to support REPL-like extensions where LLDB commands must be prefixed and additional help text is required to explain how to access traditional debugging commands.

This allows LLDB to build into and install into correctly suffixed
libdirs. This is especially significant for LLDB because the python
extension building done by CMake directly uses multilib suffixes when
the host OS does, and the host OS will not always look back and forth
between them. As a consequence, before LLVM, Clang, and LLDB (and every
other subproject) had support for using LLVM_LIBDIR_SUFFIX, you couldn't
build or install LLDB on a multilib system with its python extensions
enabled. With this patch (on top of all the others I have submitted

Most of the changes are to the FuncUnwinders class -- as we've added
more types of unwind information, the way this class was written was
making it a mess to maintain. Instead of trying to keep one
"non-call site" unwind plan and one "call site" unwind plan, track
all the different types of unwind plans we can possibly retrieve for
each function and have the call-site/non-call-site accessor methods
retrieve those.
Add a real "fast unwind plan" for x86_64 / i386 -- when doing an
unwind through a function, this only has to read the first 4 bytes
to tell if the function has a standard prologue sequence. If so,
we can use the architecture default unwind plan to backtrace
through this function. If we try to retrieve the save location for
other registers later on, a real unwind plan will be used. This
one is just for doing fast backtraces.
Change the compact unwind plan importer to fill in the valid address
range it is valid for.
Compact unwind, in theory, may have multiple entries for a single
function. The FuncUnwinders rewrite includes the start of supporting
this correctly. In practice compact unwind encodings are used for
the entire range of the function today -- in fact, sometimes the same
encoding is used for multiple functions that have the same unwind
rules. But I want to handle a single function that has multiple
different compact unwind UnwindPlans eventually.

1) 'select' based solution works ok on OSX but slows down test completion time
on Linux many times.
2) 'ioctl' base solution also works but it causes heavy processor usage on OSX
as reported by Ilia K.
But as the original hang did not occur on Linux so this commit re-introduces the
'select' in conditional code so that it only runs for OSX. There is no need for
this 'fix' to run on Linux.
Initial patch by Ilia K <ki.stfu@gmail.com>. A few changes were made by me.

Summary:
If a stream contains an empty string, no need to append it to the output
(otherwise we end up with a blank line). Also, no need to print a status
message when the state changes to connected, as this string brings no
information -- "Process 0" does not mean anything to the user, and the
process being connected has no meaning either.
Test Plan:
Connect to a remote linux platform mode daemon with `platform select
remote-linux` followed by `platform connect ...`, create a target and
run it, observe the output. Also, run the full test suite (dosep.py).

When running the test suite on Windows, we can't have Windows popping
up dialogs when LLDB crashes in native code because it will hang
the test suite. This patch silences those dialogs by checking an
environment variable at startup and configuring Windows based on
its value.
This patch also adds an environment variable to force inferiors to
never spawn in their own console window. This is useful to prevent
new window spawm when running the test suite.

The issue with Thumb IT (if/then) instructions is the IT instruction preceeds up to four instructions that are made conditional. If a breakpoint is placed on one of the conditional instructions, the instruction either needs to match the thumb opcode size (2 or 4 bytes) or a BKPT instruction needs to be used as these are always unconditional (even in a IT instruction). If BKPT instructions are used, then we might end up stopping on an instruction that won't get executed. So if we do stop at a BKPT instruction, we need to continue if the condition is not true.
When using the BKPT isntructions are easy in that you don't need to detect the size of the breakpoint that needs to be used when setting a breakpoint even in a thumb IT instruction. The bad part is you will now always stop at the opcode location and let LLDB determine if it should auto-continue. If the BKPT instruction is used, the BKPT that is used for ARM code should be something that also triggers the BKPT instruction in Thumb in case you set a breakpoint in the middle of code and the code is actually Thumb code. A value of 0xE120BE70 will work since the lower 16 bits being 0xBE70 happens to be a Thumb BKPT instruction.
The alternative is to use trap or illegal instructions that the kernel will translate into breakpoint hits. On Mac this was 0xE7FFDEFE for ARM and 0xDEFE for Thumb. The darwin kernel currently doesn't recognize any 32 bit Thumb instruction as a instruction that will get turned into a breakpoint exception (EXC_BREAKPOINT), so we had to use the BKPT instruction on Mac. The linux kernel recognizes a 16 and a 32 bit instruction as valid thumb breakpoint opcodes. The benefit of using 16 or 32 bit instructions is you don't stop on opcodes in a IT block when the condition doesn't match.
To further complicate things, single stepping on ARM is often implemented by modifying the BCR/BVR registers and setting the processor to stop when the PC is not equal to the current value. This means single stepping is another way the ARM target can stop on instructions that won't get executed.
This patch does the following:
1 - Fix the internal debugserver for Apple to use the BKPT instruction for ARM and Thumb
2 - Fix LLDB to catch when we stop in the middle of a Thumb IT instruction and continue if we stop at an instruction that won't execute
3 - Fixes this in a way that will work for any target on any platform as long as it is ARM/Thumb
4 - Adds a patch for ignoring conditions that don't match when in ARM mode (see below)
This patch also provides the code that implements the same thing for ARM instructions, though it is disabled for now. The ARM patch will check the condition of the instruction in ARM mode and continue if the condition isn't true (and therefore the instruction would not be executed). Again, this is not enable, but the code for it has been added.

Because of the way they are created, synthetic children cannot (in general) have a sane expression path
A solution to this would be letting the parent front-end generate expression paths for its children
Doing so requires a significant amount of refactoring, and might not always lead to better results (esp. w.r.t. C++ templates)
This commit takes a simpler approach:
- if a synthetic child is of pointer type and it's a target pointer, then emit *((T)value)
- if a synthetic child is a non-pointer, but its location is in the target, then emit *((T*)loadAddr)
- if a synthetic child has a value, emit ((T)value)
- else, don't emit anything

Previously if we got a DoDestroy while stopped at a breakpoint, we
would detach and then say the process had exited. This is completely
wrong, as it resulted in the python script incorrectly assuming that
the process had actually exited and trying to delete the image, when
in fact it had done no such thing.
The fix employed here is that when we get a DoDestroy, we do 3 steps:
1) initiate a termination sequence on the process
2) If we were stopped handling an exception of any kind, mask it and
let the program resume, causing the program to see the termination
request and exit on its own.
3) Let the program exit normally, and close all of our handles before
returning control back to DoDestroy.

(lldb) target create "/bin/nonono"

The problem was the initial commands 'target create "/bin/nonono"' were put into a pipe and the command interpreter was being run with:
void
CommandInterpreter::RunCommandInterpreter(bool auto_handle_events,
bool spawn_thread,
CommandInterpreterRunOptions &options)
{
// Always re-create the command intepreter when we run it in case
// any file handles have changed.
bool force_create = true;

m_stopped_for_crash = false;

{
m_debugger.StartIOHandlerThread();
}
else
{
m_debugger.ExecuteIOHanders();
if (auto_handle_events)
m_debugger.StopEventHandlerThread();
}
}
If "auto_handle_events" was set to true and "spawn_thread" was false, we would execute:
m_debugger.StartEventHandlerThread();
m_debugger.ExecuteIOHanders();
m_debugger.StopEventHandlerThread();
The problem was there was no synchonization in Debugger::StartEventHandlerThread() to ensure the event handler was listening to events and the the call to "m_debugger.StopEventHandlerThread()" would do:
void
Debugger::StopEventHandlerThread()
{
if (m_event_handler_thread.IsJoinable())
{
GetCommandInterpreter().BroadcastEvent(CommandInterpreter::eBroadcastBitQuitCommandReceived);
m_event_handler_thread.Join(nullptr);
}
}
The problem was that the event thread might not be listening for the CommandInterpreter::eBroadcastBitQuitCommandReceived event yet.
The solution is to make sure the Debugger::DefaultEventHandler() is listening to events before we return from Debugger::StartEventHandlerThread(). Once we have this synchonization we remove the race condition.

OptionValueFileSpec::SetValueFromCString() passes the c string to
FileSpec::SetFile(str, true /* resolve */) - and with Zachary's
changes to FileSpec we're using llvm::sys::fs::make_absolute() to
do that "resolve" action now, where we used to use realpath().
One important difference between llvm::sys::fs::make_absolute and
realpath is that when they're handed a filename (no directory),
realpath prepends the current working directory *and if the file exists*,
returns that full path. If that file doesn't exist, the caller
uses the basename only.
llvm::sys::fs::make_absolute prepends the current working directory
regardless of whether it exists or not.
I considered having FileSpec::SetFile save the initial pathname,
call FileSpec::Resolve, and then check to see if the Resolve return
path exists - and if not, go back to the original one.
But instead I just went with changing 'target modules load' to treat its
filename argument as a string instead of a FileSpec. This brings it
in line with how 'target modules list' works.

eh_frame data. These two pieces of information are used in the
process of exception handler unwinding on SysV ABI systems.
This patch reads the data from the eh_frame section
(DWARFCallFrameInfo.cpp), allows for it to be saved & read out
of a given UnwindPlan (UnwindPlan.h, UnwindPlan.cpp) - as well
as printing the information in the UnwindPlan::Dump method - and
adds methods to the FuncUnwinders object so that higher levels
can query if a given function has an LSDA / personality routine
defined.
It's only lightly tested, but seems to be working correctly as long
as your have this information in eh_frame. Does not address getting
this information from compact unwind yet on Darwin systems.

Fixed the prompt to not include non-printable characters as it was hosing up the prompt when you ran "command regex foo" and entered multi-line editing mode.
Fixed error strings to include more complete descriptions when bad regular expressions are entered.
Removed the old IOHandlerLinesUpdated function as it is no longer needed (inheriting from IOHandlerDelegateMultiline takes care of what this function used to do).

The problem is that editline currently is trying to be smart when we paste things into a terminal window. It detects that input is pending and multi-line input is accepted as long as there is anything pending.
So if you open lldb and paste the text between the quotes:
"command regex carp
s/^$/help/
carp
"
We still still be stuck in the "command regex" multi-line input reader as it will have all three lines:
"s/^$/help/
carp
"
The true fix for this is something Kate Stone will soon work on:
- multi-line input readers must opt into this paste/pending input feature ("expr" will opt into it, all other commands won't)
- If we are in a multi-line input reader that requests this and stuff is pasted, then it will do what it does today
- if we start in a IOHandler that doesn't need/want pending input and text is pasted, and we transistion to a IOHandler that does want this functionality, then disable the pending input. Example text would be:
"frame variable
thread backtrace
expr
for (int i=0;i<10;++i)
(int)printf("i = %i\n", i);
frame select 0
"
When we push the expression multi-line reader we would disable the pending input because we had pending input _before_ we entered "expr".
If we did this first:
(lldb) expr
Then we pasted:
"void foo()
{
}
void bar()
{
}
"
Then we would allow the pending input to not look for an empty line to terminate the expression. We filed radar 19008425 to track fixing this issue.

Previously using HostThread::GetNativeThread() required an ugly
cast to most-derived type. This solves the issue by simply returning
the derived type directly.

Previously we were directly updating the thread list and stopping
and restarting the process every time threads were created. With
this patch, we queue up thread launches and thread exits, resolve
these all internally, and only update the threads when we get an
UpdateThreadList call. We now only update the private state on
an actual stop (i.e. breakpoint).

Editline does not work correctly on Windows. This goes back at
least to r208369, and as a result r210105 was submitted to disable
libedit at runtime on Windows.
More recently, r222163 was submitted which re-writes editline
entirely, but makes the situation even worse on Windows, to the
point that it doesn't even compile. While it would be easy to
fix the compilation failure, this patch simply stops compiling
Editline entirely on Windows, as the simple compilation fix would
still result in a broken use of select on Windows, and as such a
broken implementation of Editline.
Since Editline was already disabled to begin with on Windows, we
don't attempt to fix the compilation failure or the underlying
issues, and instead just disable it "even more".
