"thread-pcs" key is added to the T (questionmark) packet in
gdb-remote protocol so that lldb doesn't need to query the
pc values of every thread before it resumes a process.
The only odd part with this is that I'm sending the pc
values in big endian order, so we need to know the endianness
of the remote process before we can use them. All other
register values in gdb-remote protocol are sent in native-endian
format so this requirement doesn't exist. This addition is a
performance enhancement -- lldb will fall back to querying the
pc of each thread individually if it needs to -- so when
we don't have the byte order for the process yet, we don't
use these values. Practically speaking, the only way I've
been able to elicit this condition is for the first
T packet when we attach to a process.

This patch reworks the breakpoint filter-by-language patch to use the
symbol context instead of trying to guess the language solely from the

will still do the same "guess"ing because Symbol::GetLanguage() is
implemented using Mangled::GuessLanguage(). The recognition of ObjC
names was merged into Mangled::GuessLanguage.

stl upper_bound method instead of lower_bound - we were
failing to find some cached data in the L1 cache resulting
in extra memory read packets while stepping.
The bug with the existing code looked like this:
If the L1 cache has 8 bytes at address 0x1000 and 8 bytes
at address 0x2000 and we are searching for 4 bytes at 0x2004,
the use of lower_bound would return the end() of the container

(the L1 cache is memory seeded from debugserver in the T aka

The standard remote debugging workflow with gdb is to start the
application on the remote host under gdbserver (e.g.: gdbserver :5039
a.out) and then connect to it with gdb.
The same workflow is supported by debugserver/lldb-gdbserver with a very
similar syntax but to access all features of lldb we need to be
connected also to an lldb-platform instance running on the target.
Before this change this had to be done manually with starting a separate
lldb-platform on the target machine and then connecting to it with lldb
before connecting to the process.
This change modifies the behavior of "platform connect" with
automatically connecting to the process instance if it was started by
the remote platform. With this command replacing gdbserver in a gdb
based worflow is usually as simple as replacing the command to execute
gdbserver with executing lldb-platform.

This is done by finding the types that are forward declarations that come from a module, and loading that module's debug info in a separate lldb_private::Module, and copying the type over into the current module using a ClangASTImporter object. ClangASTImporter objects are already used to copy types from on clang::ASTContext to another for expressions so the type copying code has been around for a while.
A new FindTypes variant was added to SymbolVendor and SymbolFile:
size_t
SymbolVendor::FindTypes (const std::vector<CompilerContext> &context, bool append, TypeMap& types);
size_t
SymbolVendor::FindTypes (const std::vector<CompilerContext> &context, bool append, TypeMap& types);
The CompilerContext is a way to represent the exact context of a type and pass it through an agnostic API boundary so that we can find that exact context elsewhere in another file. This was required here because we can have a module that has submodules, both of which have a "foo" type.
I am not able to add tests for this yet as we currently don't build our C/C++/ObjC binaries with the clang binary that we build. There are some driver issues where it can't find the header files for the C and C++ standard library which makes compiling these tests hard. We can't also guarantee that if we are building with clang that it supporst the exact format of -gmodule debugging that we are trying to test. We have had other versions of clang that had a different implementation of -gmodule debugging that we are no longer supporting, so we can't enable tests if we are building with clang without compiling something and looking at the structure of the DWARF that was generated to ensure that it is the format we can actually use.

Summary:
The following situation was occuring in TestAttachResume:
- we did a "continue" from a breakpoint (which involves a private start-stop to step over the
breakpoint)
- after receiving the stop-reply from the step-over, we issue a "detach" (which requires a
process interrupt)
- at this moment, the public state is "running", private state is "about-to-be-stopped" (the
stopped event was broadcast, but it was not received yet)
- StopForDestroyOrDetach (public thread) notes the public state is running, sends an interrupt
request to the private thread
- private thread gets the eBroadcastBitInterrupt (before the eStateStopped message), and asks the
process plugin to stop (via Halt())
- process plugin says it has nothing to do as the process is already stopped
- private thread shrugs and carries on. receives the stop event, restores the breakpoint and
resumes the process.
- after a while, the public thread times out and says it failed to stop the process
This patch does the following:
- splits Halt() into two functions, private and public, their usage depends on the context
- public Halt(): sends eBroadcastBitInterrupt to the private thread and waits for the Stop
event
- HaltPrivate(): asks the plugin to stop and makes a note that the halt was requested. When the
next stop event comes it sets the interrupt flag on it.
- removes HijackPrivateProcessEvents(), as the only user (old Halt()) has gone away
- removes the m_currently_handling_event hack, as the new Halt() does not need it
- adds a use_run_lock parameter to public Halt() and WaitForProcessToStop(). This was needed
because RunThreadPlan uses Halt() while holding the run lock and we don't want Halt() to take
it away from him.

Summary:
This makes sure we do not attempt to send output over the gdb-remote protocol when the client is
not expecting it (i.e., after sending the stop-reply packet). Normally, this should not happen
(the process cannot generate output when it is stopped), but due to the fact that pty
communication is asynchronous in the linux kernel (llvm.org/pr25652), we may sometimes get this
output too late. Instead, we just hold the output, and send it next time we resume. This is not
ideal, but at least it makes sure we do not violate the remote protocol. Given that this happens
extremely rarely it's not worth trying to work around it with sleeps or something like that.
I also remove the m_stdio_communication_mutex, as all of LLGS is now single-threaded anyway.

Summary:
- Reason of both bugs:
1. For the very first frame, Unwinder doesn't check the validity
of Full UnwindPlan before creating StackFrame from it:
When 'process launch' command is run after setting a breakpoint
in inferior, the Unwinder runs and saves only Frame 0 (the frame
in which breakpoint was set) in thread's StackFrameList i.e.
m_curr_frames_sp. However, it doesn't check the validity of the
Full UnwindPlan for this frame by unwinding 2 more frames further.
2. Unwinder doesn't update the CFA value of Cursor when Full UnwindPlan
fails and FallBack UnwindPlan succeeds in providing valid CFA values
for frames:
Sometimes during unwinding of stack frames, the Full UnwindPlan
inside the RegisterContextLLDB object may fail to provide valid
CFA values for these frames. Then the Fallback UnwindPlan is used
to unwind the frames.
If the Fallback UnwindPlan succeeds, then it provides a valid new
CFA value. The RegisterContextLLDB::m_cfa field of Cursor object
is updated during the Fallback UnwindPlan execution. However,
UnwindLLDB misses the implementation to update the 'cfa' field
of this Cursor with this valid new CFA value.
- This patch fixes both these issues.
- Remove XFAIL in test files corresponding to these 2 Bugs

of addresses, and the range has no branches, instead of running to the last instruction and
single-stepping over that, run to the first instruction after the end of the range. If there
are no branches in the current range, then the bytes right after it have to be in the current
function, and have to be instructions not data in code, so this is safe. And it cuts down one
extra stepi per source range step.
Incidentally, this also works around a bug in the llvm Intel assembler where it treats the "rep"
prefix as a separate instruction from the repeated instruction. If that were at the end of a
line range, then we would put a trap in place of the repeated instruction, which is undefined
behavior. Current processors just ignore the repetition in this case, which changes program behavior.
Since there would never be a line range break after the rep prefix, always doing the range stepping
to the beginning of the new range avoids this problem.

Summary:
Since this is within the lldb namespace, the compiler tries to
export a symbol for it. Unfortunately, since it is inlined, the
symbol is hidden and this results in a mess of warnings when
building on OS X with cmake.
Moving it to the lldb_private namespace eliminates that problem.

Summary:
On Linux, if a thread-specific conditional breakpoint was hit, it
won't necessarily be the thread that hit the breakpoint itself that
evaluates the conditional expression, so the thread that hit the
breakpoint could still be asked to stop, even though it hasn't been
allowed to run since the previous stop.

For language that support such a thing, this API allows to ask whether a type is anonymous (i.e. has been given no name)
Comes with test case

instance:
break set -l c++ -r Name
will only break on C++ symbols that match Name, not ObjC or plain C symbols. This also works
for "break set -n" and there are SB API's to pass this as well.

Memory history should not crash if it can't inspect its data. Added
error handling.

Summary:
The reason for it is limit of detecting ncurses on various systems. For
example, Ubuntu ships with <curses.h> and linkage from <ncurses.h>, <ncurses.h>
isn't detected by CMake. Detecting `<curses.h>` on NetBSD is reusing
conflicting header from the host curses(8) and pkgsrc's ncurses library.
ncurses ships on most (till conflicting) systems with curses.h. On NetBSD it
might be conflicting, so the ncurses headers are installed with pkgsrc to a
subdirectory "ncurses/".
Patch by Kamil Rytarowski. Thanks!

so when it is run on a kext (which won't activate
any platform plugins), you'll get a warning message
which may be helpful to the user.

in places where we check for Triple::IOS. They're mostly the same as far
as lldb is conerned.
.
Also add a base cass implementation for Process::IsAlive - Greg added this
last year but it didn't get upstreamed.

Summary:
This is a resubmission of r252179, but correctly ignores the source
files for other platforms.

LLDB could otherwise get confused if it is (for example) in a
root that is meant to install into an Xcode.app but hasn't
been installed yet. That way Xcode can fall back to the real
Xcode.app rather than trying to look for resources inside the
root.

This allows for command-line debugging of iOS simulator binaries (as long as UI is not required, or a full UI simulator has previously been otherwise launched), as well as execution of the LLDB test suite on the iOS simulator
This is known to compile on OSX 10.11 GM - feedback from people on other platforms and/or older versions of OSX as to the buildability of this code is greatly appreciated

callers had to do this by hand and we ended up never actually adding initial arguments and then
reusing them by passing in the struct address separately, so the distinction wasn't needed.

LLDB recently started supporting LLDB.framework without a
debugserver in it. When that happens, the Xcode-included debugserver
is searched for and used. This change fixes the code that looks for
Xcode when the housing process is not Xcode. In particular, this
addresses the problem where python is running the test suite and
the LLDB.framework does not contain a debugserver.

I am not adding a test case for this since I don't know how portable the __fp16 type is between compilers and I don't want to break the test suite.
