Zachary Turner 270e99ab0a Fix some posix assumptions related to running shell commands.
This is a resubmit of r223548, which was reverted due to breaking
tests on Linux and Mac.

This resubmit fixes the reason for the revert by adding back some
accidentally removed code which appends -c to the command line
when running /bin/sh.

This resubmit also differs from the original patch in that it sets
the architecture on the ProcessLaunchInfo.  A follow-up patch will
refactor this to separate the logic for different platforms.

Hafiz Abid Qadeer 290ece8278 Fix a bug where global variable can be reported as local.
There was an error in ORing mask which is used for getting a list of variables.
Previously, these constants were unnamed, and possible it become the reason of this
bug. Also added test case for -stack-list-local and -stack-list_arguments.

Jason Molenda e589e7e336 The lldb unwinder can now use the unwind information from the compact-unwind
section for x86_64 and i386 targets on Darwin systems.  Currently only the
compact unwind encoding for normal frame-using functions is supported but it
will be easy handle frameless functions when I have a bit more free time to
test it.  The LSDA and personality routines for functions are also retrieved
correctly for functions from the compact unwind section.

This new code is very fresh -- it passes the lldb testsuite and I've done
by-hand inspection of many functions and am getting correct behavior for all
of them.  There may need to be some bug fixing over the next couple weeks as
I exercise and test it further.  But I think it's fine right now so I'm
committing it.

Jim Ingham 33df7cd345 Add the ability to set breakpoints with conditions, commands, etc,
in the "dummy-target".  The dummy target breakpoints prime all future
targets.  Breakpoints set before any target is created (e.g. breakpoints
in ~/.lldbinit) automatically get set in the dummy target.  You can also
list, add & delete breakpoints from the dummy target using the "-D" flag,
which is supported by most of the breakpoint commands.

This removes a long-standing wart in lldb...

Sean Callanan ceeb74e606 Now that we get types from modules, we occasionally
encounter clang::ExternalASTSources that are not instances
of ClangExternalASTSourceCommon.  We used to blithely
assume that all are, and so we could use static_cast<>.
That's no longer the case, so we have to have these AST
sources register themselves.

Zachary Turner c6a6653ebb Correctly shutdown when DoDestroy is called with an active exception.
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.

This fixes Bug 21722 and Bug 21723.

Greg Clayton afa91e339b lldb can deadlock when launched with an non-existing executable:
% lldb /bin/nonono
(lldb) target create "/bin/nonono"
error: unable to find executable for '/usr/bin/nonono'
<deadlock>

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_debugger.PushIOHandler(GetIOHandler(force_create, &options));
    m_stopped_for_crash = false;
    
    if (auto_handle_events)
        m_debugger.StartEventHandlerThread();
    
    if (spawn_thread)
    {
        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.

This fixes radar:

how the 6 registers that may be saved are ordered in just 10 its

the sequence is encoded in a variable base number.  Added some
comments with references to what the code is doing so it'll be

Hafiz Abid Qadeer 05200e3b19 Re-order the base classes to prevent a crash in Linux.
In the initialization list of IOHandlerConfirm, *this is basically casting
IOHandlerConfirm to its base IOHandlerDelegate and passing it to constructor of
IOHandlerEditline which uses it and crashes as constructor of IOHandlerDelegate
is still not called. Re-ordering the base classes makes sure that constructor of
IOHandlerDelegate runs first.

It would be good to have a test case for this case too.

These methods are difficult / impossible to implement in a way

strategy (for example, i/o redirection) for achieving similar

Greg Clayton 54166af611 Fixed an issue where a DW_FORM_ref{2,4,8} might be extracted incorrectly because the wrong compile unit was being used to calculate the compile unit relative offset.
This was fixed by making the DWARFFormValue contain the compile unit that it needs so it can decode its form value correctly. Any form value that requires a compile unit will now assert. If any of the assertions that were added are triggered, then code that led to the extraction of the form value without properly setting the compile unit must be fixed immediately.

Shawn Best d64bc4bee6 fix Bug21211 : reworked test/api/multithreaded/test_listener_event_description.cpp to work properly on Linux/FreeBSD
Issue D5632 fixed an issue where linux would dump spurious output to tty on startup (due to a broadcast stop event). After the checkin, it was noticed on FreeBSD a unit test was now failing. On closer investigation I found the test was using the C++ API to launch an inferior while using an SBListener to monitor the public state changes. As on OSx, it was expecting to see:

eStateRunning
eStateStopped

On Linux/FreeBSD, there is an extra state change

eStateLaunching
eStateRunning
eStateStopped

I reworked the test to work for both cases and re-enabled the test of FreeBSD.

Ed Maste cec2a5b270 Rework parallel test process count logic
The default value for opt.thread_count was multiprocessing.cpu_count(),
which meant the LLDB_TEST_THREADS environment variable was never used.
It's not easy to pass the -t option to the test run when invoking it
from e.g. 'ninja check-lldb', so having the environment variable as an
option is useful.

Change the logic so that the thread count is set by the first one of:

  1. The -t option to test/dosep.py
  2. The LLDB_TEST_THREADS environment variable
  3. The machine's CPU count from multiprocessing.cpu_count()

Jason Molenda c6127dd653 Change CommandObjectTargetModulesLoad so that the filename argument
is treated as a string instead of a FileSpec.

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.

Zachary Turner 7f013bcd60 Rename lldb registers to contain lldb_ prefix.
LLDB supports many different register numbering schemes, and these
are typically prefixed with an indicator that lets the user know
what numbering scheme is used.  The gcc numbering scheme is
prefixed with gcc, and there are similar ones for dwarf, gdb,
and gcc_dwarf.

LLDB also contains its own internal numbering scheme, but the enum
for LLDB's numbering scheme was prefixed differently.  This patch
changes the names of these enums to use the same naming scheme for
the enum values as the rest of the register kinds by removing gpr_
and fpu_ prefixes, and instead using lldb_ prefixes for all enum
values.

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.

Greg Clayton dacf689a34 Fixed a broken test suite test after recent editline merges.
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.

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".

- Add the ability to set the listener in SBLaunchInfo and SBAttachInfo in case you don't want to use the debugger as the default listener. 
- Modified all places that use the SBLaunchInfo/SBAttachInfo and the internal ProcessLaunchInfo/ProcessAttachInfo to not take a listener as a parameter since it is in the launch/attach info now
- Load a module's sections by default when removing a module from a target. Since we create JIT modules for expressions and helper functions, we could end up with stale data in the section load list if a module was removed from the target as the section load list would still have entries for the unloaded module. Target now has the following functions to help unload all sections a single or multiple modules:

    size_t
    Target::UnloadModuleSections (const ModuleList &module_list);

    size_t
    Target::UnloadModuleSections (const lldb::ModuleSP &module_sp);

Kate Stone e30f11d9ee Complete rewrite of interactive editing support for single- and multi-line input.
Improvements include:
* Use of libedit's wide character support, which is imperfect but a distinct improvement over ASCII-only
* Fallback for ASCII editing path
* Support for a "faint" prompt clearly distinguished from input
* Breaking lines and insert new lines in the middle of a batch by simply pressing return
* Joining lines with forward and backward character deletion
* Detection of paste to suppress automatic formatting and statement completion tests
* Correctly reformatting when lines grow or shrink to occupy different numbers of rows
* Saving multi-line history, and correctly preserving the "tip" of history during editing
* Displaying visible ^C and ^D indications when interrupting input or sending EOF
* Fledgling VI support for multi-line editing
* General correctness and reliability improvements

Greg Clayton 35c91347e6 Fixes for remote test suite execution of the "lldb/test/lang" directory.
Fixes include:
- Add a new lldbtest.TestBase function named registerSharedLibrariesWithTarget. This function can be called using the shared libraries for your test suite either as shared library basename ("foo"), path basename ("libfoo.dylib") or full path ("/tmp/lldb/test/lang/c/carp/libfoo.dylib"). These shared libraries are then registered with the target so they will be downloaded when the test is run remotely. 
- Changed a lot of tests over to use SBDebugger::CreateTarget(...) calls instead of using "file a.out" commands.
- Cleaned up some tests to add new locations for breakpoints that all compilers should be able to abide by. Some tests and constants being loaded into values of structs and some compilers like arm64 will often combine two constant data loads into a single source line so some breakpoint locations were not being set correctly. Adding lines like 'puts("")' allow us to lock onto a source line that will have code.

Zachary Turner 119767db85 [ProcessWindows] Create a TargetThreadWindows class.
This creates a TargetThreadWindows class and updates the thread
list of the Process with the main thread.  Additionally, we
fill out a few more overrides of Process base class methods.  We
do not yet update the thread list as threads are created and/or
destroyed, and we do not yet propagate stop reasons to threads as
their states change.

Ed Maste 9251e2e61c Add decorator for intermittently failing test on FreeBSD
This test has intermittently failed on FreeBSD for quite some time when
run as part of the full test suite.  It generally passes when run by
itself.  Mark as expected failure for now to reduce buildbot noise.

Jason Molenda b412e529e2 Add a little sketch of a program that can extract unwind
information from the compact unwind section used on darwin
for exception handling, and dump that information..

The UNWIND_X86_64_MODE_RBP_FRAME and UNWIND_X86_64_MODE_DWARF
entries look to be handled correctly.

UNWIND_X86_64_MODE_STACK_IMMD and UNWIND_X86_64_MODE_STACK_IND 
are still a work in progress.

Only x86_64 is supported right now.  Given that this is an
experiment in parsing the section contents, I don't expect to
add other architectures; they are trivial variations on this
arch.  There exists a real dumper included in the Xcode tools, 
unwinddump.

Jim Ingham 96a1596a7a For some reason, sometimes the directory paths that clang emits have internal
relative paths, like:

/whatever/llvm/lib/Sema/../../include/llvm/Sema/

That causes problems with our type uniquing, since we use the declaration file
and line as one component of the uniquing, and different ways of getting to the
same file will have different directory spellings, though they are functionally
equivalent.  We end up with two copies of the exact same type because of this, 
and that makes the expression parser give "duplicate type" errors.

I added a method to resolve paths with ../ in them and used that in the FileSpec::Equals,
for comparing Declarations and for doing Breakpoint compares as well, since they also
suffer from this if you specify breakpoints by full path (since nobody knows what
../'s to insert...)

Shawn Best 954eae0ed4 add Makefile rule for test program CREATE_STD_THREADS
Effectively removes -lpthreads from linux/gcc build of test programs in test/api/multithreaded. This was done due to that combination causing a test program to hang due, likely due to an issue with gcc linker and libstdc++ conflicting pthreads code in test program and pthread used by lldb.
