This does not work and causes the class to be silently skipped, which is a bad idea. This makes
sure it cannot happen accidentaly. I've played with the idea of actually making the decorator
work at class level, but it proved too magic to do at this moment.

The ELF symbol table always contain the size of the symbols so we
don't have to try to guess them based on the address of the next
symbol (it is needed for mach-o).
The change fixes an issue when a symbol is removed after a 0 size
symbol (e.g. because the second one is not public) what previously
caused the symbol lookup algorithm to end up with showing the 0 size
symbol even for the later addresses (what are not part of any symbol).
That symbol lookup error can confuse the user and also confuses the
current stack unwinder.

Reverts earlier commit r254910, which used function pointers for jitted expressions
to avoid a Mips64 compiler bug. Bug has since been fixed, and compiler longer issues the problem instruction.

TestConcurrentEvents was marked with a XFAIL decorator at class level, which actually does not
work, and causes the class to be silently skipped everywhere. It seems that making it work at
class level is quite a difficult task, so I will just move it to the individual test methods. I
will follow this up with a commit which makes the decorator blow up in case someone tries to
apply it to a class in the future.

1) It was forward declaring functions without 'extern "C"'. That used to work
but only because of another bug in how we passes symbol only function names to the
compiler and stopped working recently.
2) These forward declarations were in the body of the User Expression, and they actually
need to go in the prefix file.

If your program refers to modules (as indicated in DWARF) we will now try to
load these modules and give you access to their types in expressions. This used
to be gated by a setting ("settings set target.auto-import-clang-modules true")
but that setting defaulted to false. Now it defaults to true -- but you can
disable it by toggling the setting to false.

Both llvm and clang have an ArrayType class, which can cause resolution to fail when llvm headers that are implicitly included name this type.

The Green Dragon LLVM builders are starting to parse xunit output
on LLDB Xcode builders. By default the XML formatter treats
xpass (unexpected successes) as failures. The new flag added
ensures we simply ignore those for purposes of xUnit output.
LLDB is not currently XPASS clean.

If you have two folders with the same name but different cases,
MSBuild gets confused and generates an error when building

This patch renames it so that the cases of all folders named

We already have char** typemaps which were near copy-pastes of
the const char** versions. This way we have only one version that
works for both.

There were a number of problems preventing this from working:
1. The SWIG typemaps for converting Python lists to and from C++
arrays were not updated for Python 3. So they were doing things
like PyString_Check instead of using the PythonString from
PythonDataObjects.
2. ProcessLauncherWindows was ignoring the environment completely.
So any test that involved launching an inferior with any kind
of environment variable would have failed.
3. The test itself was using process.GetSTDOUT(), which isn't
implemented on Windows. So this was changed to save the
value of the environment variable in a local variable and
have the debugger look at the value of the variable.

Most of the time CONFIGURATION_BUILD_DIR and BUILT_PRODUCTS_DIR are the same,
but they are different in 'xcodebuild install' situations. The file needs to be
put into BUILT_PRODUCTS_DIR or lldb's Python interface doesn't work when lldb is
built using 'xcodebuild install'.

We have a check what warns if the offset of a class member is greater
then or equal to the size of the class. The warning is valid in most
case but it is invalid when the last data member is a 0 size array
because in this case the member offset can be equal to the class size
(subject to alignment limitations).
This CL fixis LLDB to not print out a warning in this special case.

This is a packet which allows the remote gdb stub to ask for the address
of a symbol in the process. lldb sends the packet (offering to provide
addresses for symbol names) after every solib loaded. I changed lldb so
that once the stub has indicated that it doesn't need any more symbol
addresses, lldb will stop sending the qSymbol:: packet on new solib loads.
This can yield a performance benefit over slower communication links when
there are many solibs involved.

The system can create threads for a system threadpool, so there is
no guarantee that the thread that is stopped is thread 1. So use
a more robust check.
llvm-svn: 257513
Summary:
Allows the remote to enumerate the link map when adding and removing
shared libraries, so that lldb doesn't need to read it manually from
the remote's memory.
This provides very large speedups (on the order of 50%) in total
startup time when using the ds2 remote on android or Tizen devices.

llvm-svn: 257502
Summary:
The testcase TestNoreturnUnwind.py was failing
because the unwind from the vdso library was not
successful for clang compiler while it was passing
for gcc. It was passing for gcc since the unwind plan
used was the assembly plan and the ebp register was
set by the main function in case of gcc and was not
used by the functions in the call flow to the vdso, whereas
clang did not emit assembly prologue for main and so
the assembly unwind was failing. Normally in case of
failure of assembly unwind, lldb switches to EH CFI frame
based unwinding, but this was not happening for
the first frame. This patch tries to fix this behaviour by
falling to EH CFI frame based unwinding in case of assembly
unwind failure even for the first frame.
The test is still marked as XFAIL since it relys on the fix
of another bug.

at each public stop to improve performance a bit. Most of the
information lldb needed was already in the jThreadsInfo response;
complete that information and catch a few cases where we could still
fall back to getting the information via discrete memory reads.
debugserver adds 'associated_with_dispatch_queue' and 'dispatch_queue_t
keys to the jThreadsInfo response for all the threads. lldb needs the
dispatch_queue_t value. And associated_with_dispatch_queue helps to
identify which threads definitively don't have any queue information so
lldb doesn't try to do memory reads to get that information just because
it was absent in the jThreadsInfo response.
Remove the queue information from the questionmark (T) packet. We'll
get the information for all threads via the jThreadsInfo response -
sending the information for the stopping thread (on all the private
stops, plus the less frequent public stop) was unnecessary information
being sent over the wire.
SystemRuntimeMacOSX will try to get information about queues by asking
the Threads for them, instead of reading memory.
ProcessGDBRemote changes to recognize the new keys being sent in the
jThreadsInfo response. Changes to ThreadGDBRemote to track the new
information. Also, when a thread is marked as definitively not
associated with a libdispatch queue, don't fall back to the system
runtime to try memory reads to find the queue name / kind / ID etc.
