Enrico Granata c3b0a5b099 In some cases, type lookup has to deal with situations where it cannot reconstruct a compile unit or a function, but it still has a valid symbol - and it can use that in order to figure out the preferential language for lookups
This is not the right thing for all clients (notably the expression parser), so put it in type lookup specific code

Fixes rdar://problem/22422313

Pavel Labath 7189b0fdb2 Fix logging in Listener.cpp
Clear() log message was claiming it was the destructor, which had me very confused when looking
at the log messages. Fix the message, and add a log message to the real destructor.

Also noticed that the destructor was needlessly locking the broadcaster mutex (as Clear was
locking it again anyway), so remove that as well.

Pavel Labath ebc7135f8e Fix race in TestExitDuringStep and unify pseudo_barrier handling
Summary:
TestExitDuringStep was very rarely hanging on the buildbots. I can't be sure, but I believe this
was because of the fact that it declared its pseudo_barrier variable as "volatile int", which is
not sufficient to guarantee corectness (also, all other tests used atomic variables for this, and
they were passing reliably AFAIK). Besides switching to an atomic variable in this test as well,
I have also took this opportunity to unify all the copies of the pseudo_barrier code to a single
place to reduce the chance of this happening again.

Sean Callanan f52c40c57f Fixed multiline expressions, and removed some dead code.
IOHandlerLinesUpdated() does nothing, and IOHandlerIsInputComplete should be
implemented but isn't.  This means that multiline expressions don't work.  This
patch fixes that.  Test case to follow in the next commit.

Jim Ingham 9b8eb155d8 Fix the way the ShouldStopHere checker handles the general case of "stepping through line 0 code".
That's good 'cause it means all the different kinds of source line stepping won't leave user in the middle of
compiler implementation code or code inlined from odd places, etc.  But it turns out that the compiler
also marks functions it MIGHT inline as all being of line 0.  That would mean we single step through this code
instead of just stepping out.  That is both inefficient, and more error prone 'cause these little nuggets tend
to be bits of hand-written assembly and the like and are hard to step through.

This change just checks and if the entire function is marked with line 0, we step out rather than step through.

Enrico Granata 5f57b6ee0f Revert r268591
"Allow LanguageRuntimes to return an error if they fail in the course of dynamic type discovery

This is not meant to report that a value doesn't have a dynamic type - it is only meant as a mechanism to propagate actual type discovery issues (e.g. malformed type metadata for languages that have such a notion)

This information is used by ValueObjectDynamic to set its own m_error, which is a fairly sharp and heavyweight tool to begin with

For the time being, this is an architectural improvement but a practical no-op as no existing runtimes are actually setting errors"

I need to think about what I want to do in this space more carefully - this attempt might be too heavy of a hammer for the nail I am trying to fix, and I don't want to leave it in while I ponder

Todd Fiala 57a4e5b3d0 Fix TestEvents.py on OS X
This change addresses a hang/segfault in TestEvents.py. The threads that
run the listener loops now do an SBListener.Clear() before they wrap up
their work. This prevents the test from trying to clean up the
SBListener too late.

There is a separate issue here which is that we should prevent this
clean-up time lock-up, but that is out of scope for this particular
change. I'd like to get these tests back and running the normal flow
rather than skipping them.

This addresses:
llvm.org/pr25924 (at least, the OS X side, although I suspect this will
also address Linux)

Adrian McCarthy 3f99810787 XFail TestLambdas.py on Windows after fixing some of the problems
1. Fixed semicolon placement in the lambda in the test itself.

2. Fixed lldbinline tests in general so that we don't attempt tests on platforms that don't use the given type of debug info. (For example, no DWO tests on Windows.) This fixes one of the two failures on Windows. (TestLambdas.py was the only inline test that wasn't XFailed or skipped on Windows.)

3. Set the error string in IRInterpreter::CanInterpret so that the caller doesn't print (null) instead of an explanation. I don't entirely understand the error, so feel free to suggest a better wording.

4. XFailed the test on Windows. The interpreter won't evaluate the lambda because the module has multiple function bodies. I don't exactly understand why that's a problem for the interpreter nor why the problem arises only on Windows.

We don't want a mutex in debugger as it will cause A/B locking issues with the lldb_private::Target's mutex, but we do need to stop two threads from doing Debugger::Clear at the same time. We have seen issues with this with the C++ global destructor chain where the global debugger list is being destroyed and the Debugger::~Debugger() is calling it while another thread was in the middle of running that function.

Jason Molenda 955dcf2dbc Add a way for an ObjectFile to indicate that assembly emulation
should not be used for this module -- for use when an ObjectFile
knows that it does not have meaningful or accurate function start
addresses.  

More commonly, it is not clear that function start addresses are
missing in a module.  There are certain cases on Mac OS X where we
can tell that a Mach-O binary has been stripped of this essential
information, and the unwinder can end up emulating many megabytes
of instructions for a single "function" in the binary.

When a Mach-O binary is missing both an LC_FUNCTION_STARTS load 
command (very unusual) and an eh_frame section, then we will assume 
it has also been stripped of symbols and that instruction emulation
will not be useful on this module.

Pavel Labath 240760207e Add a read_full_buffer argument to ConnectionFileDescriptor::Read
Summary:
AdbClient was attempting to handle the case where the socket input arrived in pieces, but it was
failing to handle the case where the connection was closed before that happened. In this case, it
would just spin in an infinite loop calling Connection::Read. (This was also the cause of the
spurious timeouts on the darwin->android buildbot. The exact cause of the premature EOF remains
to be investigated, but is likely a server bug.)

Since this wait-for-a-certain-number-of-bytes seems like a useful functionality to have, I am
moving it (with the infinite loop fixed) to the Connection class, and adding an
appropriate test for it.
