86e4d7ea35 [lldb] [lldbsuite] Use a unique class name for TestValueVarUpdate
It looks like when this test was added, it was based on TestHelloWorld and it ended up with the same class name. This is an issue because the logs associated with the tests use the class name as the identifier for the file and if two tests have the same name their logs overwrite each other. On non-windows, this just means we lose one of the logs, but on Windows this means that one of the tests will fail occasionally because the file are locked by the other test.

21929d49d5 Revert "Disable the step over skipping calls feature since buildbots are not happy."
While this fixed the windows bot failures, it also broke all other bots.

Upon closer inspection, it turns out that the windows bots were "broken"
because two tests were unexpectedly passing -- i.e., the original patch
(r360375) actually improved our stepping support on windows.

So instead, I remove the relevant XFAILs.

This reverts commit r360397.

539b7e65b4 Make TestPrintStackTraces deterministic
This test contained an incredibly complicated inferior, but in reality,
all it was testing was that we can backtrace up to main and see main's
arguments.

However, the way this was implemented (setting a breakpoint on a
separate thread) meant that each time the test would run, it would stop
in a different location on the main thread. Most of the time this
location would be deep in some libc function, which meant that the
success of this test depended on our ability to backtrace out of a
random function of the c library that the user happens to have
installed.

This makes the test unpredictable. Backtracing out of a libc function is
an important functionality, but this is not the way to test it. Often it
is not even our fault that we cannot backtrace out because the C library
contains a lot of assembly routines that may not have correct unwind
info associated with them.

For this reason the test has accumulated numerous @expectedFail/Flaky
decorators. In this patch, I replace the inferior with one that does not
depend on libc functions. Instead I create a couple of stack frames of
user code, and have the test verify that. I also simplify the test by
using lldbutil.run_to_source_breakpoint.

4da5a1dbab modify-python-lldb.py: clean up __iter__ and __len__ support
Summary:
Instead of modifying the swig-generated code, just add the appropriate
methods to the interface files in order to get the swig to do the
generation for us.

This is a straight-forward move from the python script to the interface
files. The single class which has nontrivial handling in the script
(SBModule) has been left for a separate patch.

For the cases where I did not find any tests exercising the
iteration/length methods (i.e., no tests failed after I stopped emitting
them), I tried to add basic tests for that functionality.

8d6b60c14c Embed swig version into lldb.py in a different way
Summary:
Instead of doing string chopping on the resulting python file, get swig
to output the version for us. The two things which make slightly
non-trivial are:
- in order to get swig to expand SWIG_VERSION for us, we cannot use
  %pythoncode directly, but we have to go through an intermediate macro.
- SWIG_VERSION is a hex number, but it's components are supposed to be
  interpreted decimally, so there is a bit of integer magic needed to
  get the right number to come out.

I've tested that this approach works both with the latest (3.0.12) and
oldest (1.3.40) supported swig.

2946cd7010 Update the file headers across all of the LLVM projects in the monorepo
to reflect the new license.

We understand that people may be surprised that we're moving the header
entirely to discuss the new license. We checked this carefully with the
Foundation's lawyer and we believe this is the correct approach.

Essentially, all code in the project is now made available by the LLVM
project under our new license, so you will see that the license headers
include that license only. Some of our contributors have contributed
code under our old license, and accordingly, we have retained a copy of
our old license notice in the top-level files in each project and

f3a9ab07aa Fix a couple of more tests to not create files in the source tree
Summary:
These were not being flaky, but they're still making the tree dirty.

These tests were using lldbutil.append_to_process_working_directory to
derive the file path so I fix them by modifying the function to return
the build directory for local tests.

Technically, now the path returned by this function does not point to
the process working directory for local tests, but I think it makes
sense to keep the function name, as I think we should move towards
launching the process in the build directory (and I intend to change
this for the handful of inferiors that actually care about their PWD,
for example because they need to create files there).

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.

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.)

b8318155eb Enable TestReadMemCString on non-darwin targets
The test works fine on linux, and I believe other targets should not
have an issue with as well. If they do, we can start blacklisting
instead of whitelisting.

The idea of using "-1" as the value of the pointer on non-apple targets
backfired, as it fails the "address != LLDB_INVALID_ADDRESS" test (-1 is
the value of LLDB_INVALID_ADDRESS).  However, it should be safe to use
0x100 for other targets as well. The first page of memory is generally

fd9a526a30 Makefile.rules: compile all tests with -fno-limit-debug-info
Summary:
This flag is on by default for darwin and freebsd, but off for linux.
Without it, clang will sometimes not emit debug info for types like
std::string. Whether it does this, and which tests will fail because of
that depends on the linux distro and c++ library version.

A bunch of tests were already setting these flags manually, but here
instead I take a whole sale approach and enable this flag for all tests.
Any test which does not want to have this flag (right now we have one
such test) can turn it off explicitly via
CFLAGS_EXTRAS+=$(LIMIT_DEBUG_INFO_FLAGS)

This fixes a bunch of data formatter tests on red-hat.

The motivation behind this is to provide an easy way to disable watchpoint
tests on systems where the watchpoint functionality is not present/unreliable.

8652b249e6 Initial patchset to get the testsuite running against armv7 and arm64 iOS devices.
Normal customer devices won't be able to run these tests, we're hoping to get
a public facing bot set up at some point.  Both devices pass the testsuite without
any errors or failures.

I have seen some instability with the armv7 test runs, I may submit additional patches
to address this.  arm64 looks good.

I'll be watching the bots for the rest of today; if any problems are introduced by
this patch I'll revert it - if anyone sees a problem with their bot that I don't
see, please do the same.  I know it's a rather large patch.

One change I had to make specifically for iOS devices was that debugserver can't 
create files.  There were several tests that launch the inferior process redirecting
its output to a file, then they retrieve the file.  They were not trying to test
file redirection in these tests, so I rewrote those to write their output to a file
directly.
