Jason Molenda a6f75467da Add support for UNWIND_X86_64_MODE_STACK_IND entries.
Correct the function offset computations in UNWIND_SECOND_LEVEL_REGULAR
tables.  A few other small fixes.

Jason Molenda 671001cc66 A little more work on the compact unwind dumper.
UNWIND_X86_64_MODE_STACK_IND mode is almost correct; extra stack
space allocated before the reg saves isn't handled right.  Still a
little wobbily on the file addresses of functions.  Finally understand
how the 6 registers that may be saved are ordered in just 10 its
of space -- the Lehmer code for the registers is derived and then
the sequence is encoded in a variable base number.  Added some
comments with references to what the code is doing so it'll be
easier for others to track down.

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

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.

sure we change all of the object ivars that might be used in
the process of fetching the CFA & caller's saved pc value 
and restore those if we decide not to use the fallback 
unwindplan.

Jim Ingham 893c932acf This is the first step of making lldb able to create target-specific things
(e.g. breakpoints, stop-hooks) before we have any targets - for instance in 
your ~/.lldbinit file.  These will then get copied over to any new targets 
that get created.  So far, you can only make stop-hooks.

Breakpoints will have to learn to move themselves from target to target for
us to get them from no-target to new-target.

We should also make a command & SB API way to prime this ur-target.

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.

adds a sanity check for that fallback unwind plan -- it must

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.

Zachary Turner 1019695b38 Move the thread logic around to fit better into LLDB's process model.
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).

Zachary Turner d553d00c79 Disable Editline on Windows.
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".

Greg Clayton 8012cadbf3 Fixed more fallout from running the test suite remotely on iOS devices.
Fixed include:
- Change Platform::ResolveExecutable(...) to take a ModuleSpec instead of a FileSpec + ArchSpec to help resolve executables correctly when we have just a path + UUID (no arch).
- 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);

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.

The UNWIND_X86_64_MODE_RBP_FRAME and UNWIND_X86_64_MODE_DWARF

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,

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...)

Greg Clayton bf702ceed1 Fixed "SBTarget SBDebugger::CreateTarget (const char *filename)" to use the same semantics as other SBDebugger::CreateTarget() functions.
The issues were:
- If you called this function with any arch other than the default target architecture, creating the target would fail because the Target::GetDefaultArchitecture() would not match the single architecture in the file specified. This caused running the test suite remotely with lldb-platform to fail many many tests due to the bad target.
- It would specify the currently selected platform which might not work for the specified platform

All other SBDebugger::CreateTarget calls do not assume an architecture or platform and if they aren't specified, they don't auto select the wrong one for you.

With this fix, SBTarget SBDebugger::CreateTarget (const char *filename) now behaves like the other SBDebugger::CreateTarget() variants.

Zachary Turner dcd80377f3 [ProcessWindows] Implement breakpoint stop / resume on Windows.
This patch implements basic support for stopping at breakpoints
and resuming later.  While a breakpoint is stopped at, LLDB will
cease to process events in the debug loop, effectively suspending
the process, and then resume later when ProcessWindows::DoResume

As a side effect, this also correctly handles the loader breakpoint
(i.e. the initial stop) so that LLDB goes through the correct state

Ed Maste 29a4584484 Fix new noreturn test on !darwin platforms
r221575 introduced a NoreturnUnwind test that did not skip the dsym
test on non-darwin platforms, and had the @dwarf_test case as an exact
copy of the dsym case (including the test name, test_with_dsym).

Jason Molenda bd07fd57f6 Add a RegisterNumber class to RegisterContextLLDB.h and start using
it in RegisterContext.cpp.

There's a lot of bookkeeping code in RegisterContextLLDB where it has
to convert between different register numbering schemes and it makes 
some methods like SavedLocationForRegister very hard to read or
maintain.  Abstract all of the details about different register numbering
systems for a given register into this new class to make it easier 
to understand what the method is doing.

Also add register name printing to all of the logging -- that's easy to
get now that I've got an object to represent the register numbers.

There were some gnarly corner cases of this method that I believe
I've translated correctly - initial testing looks good but it's
possible I missed a corner case, especially with architectures which
uses a link-register aka return address register like arm32/arm64.
Basic behavior is correct but there are a lot of corner casese that are
handled in this method ...

Jason Molenda cf29675d95 Fix a corner case with the handling of noreturn functions.
If a noreturn function was the last function in a section,
we wouldn't correctly back up the saved-pc value into the
correct section leading to us showing the wrong function in
the backtrace.

Also add a backtrace test with an attempt to elicit this 
particular layout.  It happens to work out with clang -Os
but other compilers may not quite get the same layout I'm
getting at that opt setting.  We'll still be exercising the
basic noreturn handling in the unwinder even if we don't get
one function at the very end of a section.

Zachary Turner 02862bc83a Remove the top-level DebugDriverThread in ProcessWindows.
Originally the idea was that we would queue requests to a master
thread that would dispatch them to other slave threads each
responsible for debugging an individual process.  This might make
some scenarios more scalable and responsive, but for now it seems
to be unwarranted complexity for no observable benefit.

Enrico Granata 03c9635199 SBValue::Cast is deprecated. This does not work as reliably as free-form casting via the expression evaluator. Some of our clients depend on it, so we can't remove it. But any new adopters should favor the expression parser as the way forward

Greg Clayton 860fac5338 Fixes so tests compile and run remotely.
Fixes include:
- dont set or change LDFLAGS, but set LD_EXTRAS instead
- fix compilation errors for iOS based builds with objective C code
    - fix test cases to create classes instead of relying on classes from AppKit 
    - rename things where it makes sense

Enrico Granata f35bc63220 This is a large, but clearical, commit that enables the C++ formatters to take on the additional TypeSummaryOptions argument. It is still not used for anything, but it is now there. Adding support for this extra argument to Python formatters will follow suit

Enrico Granata c1247f5596 Introduce the notion of "type summary options" as flags that can be passed down to individual summary formatters to alter their behavior in a formatter-dependent way
Two flags are introduced:
- preferred display language (as in, ObjC vs. C++)
- summary capping (as in, should a limit be put to the amount of data retrieved)

The meaning - if any - of these options is for individual formatters to establish
The topic of a subsequent commit will be to actually wire these through to individual data formatters
