Adrian Prantl e885768640 Create a marker for Spotlight to never index $BUILD_DIR.
LLDB queries Spotlight to locate .dSYM bundles based on the UUID
embedded in a binary, and because the UUID is a hash of filename and
.text section, there *will* be conflicts inside $BUILD_DIR.

This should fix the broken green dragon bots.

Jim Ingham 0423fcac39 Added lldbutil.run_to_name_breakpoint and use it in one test.
Using the "run_to_{source,name}_breakpoint will allow us to remove
a lot of boiler-plate from the testsuite.  We mostly use source
breakpoints, but some tests use by name ones so this was needed.

Pavel Labath 71ad71e530 mock_gdb_server: rectify ack handling code
The mock server was sending acks back in response to spurious acks from
the client, but the client was not prepared to handle these. Most of the
time this would work because the only time the client was sending
unsolicited acks is after the initial connection, and there reply-ack
would get ignored in the "flush all packets from the server" loop which
came after the ack. However, this loop had only a 10ms delay, and
sometimes this was not enough to catch the reply (which meant the
connection got out of sync, and test failed).

Since this behavior not consistent with how lldb-server handles this
situation (it just ignores the ack), I fix the mock server to do the
same.

Adrian Prantl 5ec76fe720 Compile the LLDB tests out-of-tree.
This patch is the result of a discussion on lldb-dev, see
http://lists.llvm.org/pipermail/lldb-dev/2018-January/013111.html for
background.

For each test (should be eventually: each test configuration) a
separate build directory is created and we execute

  make VPATH=$srcdir/path/to/test -C $builddir/path/to/test -f $srcdir/path/to/test/Makefile -I $srcdir/path/to/test

In order to make this work all LLDB tests need to be updated to find
the executable in the test build directory, since CWD still points at
the test's source directory, which is a requirement for unittest2.

Although we have done extensive testing, I'm expecting that this first
attempt will break a few bots. Please DO NOT HESITATE TO REVERT this
patch in order to get the bots green again. We will likely have to
iterate on this some more.

Pavel Labath 1902ffd9a4 [lldb] Generic base for testing gdb-remote behavior
Summary:
Adds new utilities that make it easier to write test cases for lldb acting as a client over a gdb-remote connection.

- A GDBRemoteTestBase class that starts a mock GDB server and provides an easy way to check client packets
- A MockGDBServer that, via MockGDBServerResponder, can be made to issue server responses that test client behavior.
- Utility functions for handling common data encoding/decoding
- Utility functions for creating dummy targets from YAML files

Vedant Kumar 801362f067 Use test-specific module caches to avoid stale header conflicts
Stale global module caches cause problems for the bots. The modules
become invalid when clang headers are updated by version control, and
tests which use these modules fail to compile, e.g:

  fatal error: file '.../__stddef_max_align_t.h' has been modified since the module file '/var/.../Darwin.pcm' was built
  note: please rebuild precompiled header '/var/.../Darwin.pcm'

Eventually we should transition to having just a single module cache to speed
tests up. This patch should be just enough to fix the spurious bot failures due
to stale caches.

Lang Hames 48b32f4ced [lldb] Fix some C++ virtual method call bugs in LLDB expression evaluation by
building method override tables for CXXMethodDecls in 
DWARFASTParserClang::CompleteTypeFromDWARF.

C++ virtual method calls in LLDB expressions may fail if the override table for
the method being called is not correct as IRGen will produce references to the
wrong (or a missing) vtable entry.

This patch does not fix calls to virtual methods with covariant return types as
it mistakenly treats these as overloads, rather than overrides. This will be
addressed in a future patch.

Jim Ingham 5ec7cd7227 Fix Breakpoint::RemoveInvalidLocations to fix the exec testcase.
RemoveInvalidLocations was clearing out the m_locations in the
breakpoint by hand, and it wasn't also clearing the locations from
the address->location map, which confused us when we went to update
breakpoint locations.  

I also made Breakpoint::ModulesChanged check the Location's Section
to make sure it hadn't been deleted.  This shouldn't strictly be necessary,
but if the DynamicLoaderPlugin doesn't do it's job right (I'm looking at
you new Darwin DynamicLoader...) then it can end up leaving stale locations
on rerun.  It doesn't hurt to clean them up here as a backstop.

Pavel Labath 62930e57eb Add Utility/Environment class for handling... environments
Summary:
There was some confusion in the code about how to represent process
environment. Most of the code (ab)used the Args class for this purpose,
but some of it used a more basic StringList class instead. In either
case, the fact that the underlying abstraction did not provide primitive
operations for the typical environment operations meant that even a
simple operation like checking for an environment variable value was
several lines of code.

This patch adds a separate Environment class, which is essentialy a
llvm::StringMap<std::string> in disguise. To standard StringMap
functionality, it adds a couple of new functions, which are specific to
the environment use case:
- (most important) envp conversion for passing into execve() and likes.
  Instead of trying to maintain a constantly up-to-date envp view, it
  provides a function which creates a envp view on demand, with the
  expectation that this will be called as the very last thing before
  handing the value to the system function.
- insert(StringRef KeyEqValue) - splits KeyEqValue into (key, value)
  pair and inserts it into the environment map.
- compose(value_type KeyValue) - takes a map entry and converts in back
  into "KEY=VALUE" representation.

With this interface most of the environment-manipulating code becomes
one-liners. The only tricky part was maintaining compatibility in
SBLaunchInfo, which expects that the environment entries are accessible
by index and that the returned const char* is backed by the launch info
object (random access into maps is hard and the map stores the entry in
a deconstructed form, so we cannot just return a .c_str() value). To
solve this, I have the SBLaunchInfo convert the environment into the
"envp" form, and use it to answer the environment queries. Extra code is
added to make sure the envp version is always in sync.

(This also improves the layering situation as Args was in the Interpreter module
whereas Environment is in Utility.)
