16624b8ca6 [dotest] Remove the curses result formatter.
This removes the curses result formatter which appears to be broken.
Passing --curses to dotest.py screws up my terminal and doesn't run any
tests. It even crashes Python on occasion.

165d47969a [dotest] Don't try to guess the llvm binary dir.
Now that all supported build systems create a valid dotest.py
invocation, we no longer need to guess the directory where any of the
llvm tools live. Additionally, the current logic is incomplete: it
doesn't try to find any other tools than FileCheck, such as dsymutil for
example.

If no FileCheck is provided, we should print a warning and skip the
tests that need it, but that's not part of this patch.

b543c16869 [dotest] Remove -q (quiet) flag.
This patch removes the -q (quiet) flag and changing the default
behavior. Currently the flag serves two purposes that are somewhat
contradictory, as illustrated by the difference between the argument
name (quiet) and the configuration flag (parsable). On the one hand it
reduces output, but on the other hand it prints more output, like the
result of individual tests. My proposal is to guard the extra output
behind the verbose flag and always print the individual test results.

The single-process test runner is invoked in a number of different
scenarios, including when multiple test dirs are specified or (afaict)

Unfortunately the --test-subdir option did not work with the single

  Failure URL: https://ci.swift.org/job/swift-PR-Linux/6841

87951b6693 [testsuite] Implement a category to skip libstdcxx tests
On systems where it's not supported.
As far as I understand Linux is the only systems which now ships
with libstdcxx (maybe NetBSD?, but I'm not entirely sure of the
state of lldb on the platform).
We could make this more fine grained looking for the header as
we do for libcxx. This is a little tricky as there's no such
thing as /usr/include/c++/v1, but libstdcxx encodes the version
number in the path (i.e. /usr/include/c++/5.4). I guess we might
match a regex, but it seems fragile to me.

fdfeefd6c2 [dotest] Make the set of tests independent of the test configuration
Summary:
In the magic test duplicator, we were making the decision whether to
create a test variant based on the compiler and the target platform.
This meant that the set of known tests was different for each test
configuration.

This patch makes the set of generated test variants static and handles
the skipping via runtime checks instead. This is more consistent with
how we do other test-skipping decision (e.g. for libc++ tests), and
makes it easier to expose the full set of tests to lit, which now does
not need to know anything about what things can potentially cause tests
to appear or disappear.

45ae11cd80 [test] Skip a test when using an out-of-tree debugserver
The test "test_fp_special_purpose_register_read" in TestRegisters.py
fails on Darwin machines configured to use an out-of-tree debugserver.

The error message is: 'register read ftag' returns expected result, got
'ftag = 0x80'. This indicates that the debugserver in use is too old.

This commit introduces a decorator which can be used to skip tests which
rely on having a just-built debugserver. This resolves the issue:

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.

01a28ca7f8 Centralize libc++ test skipping logic
Summary:
This aims to replace the different decorators we've had on each libc++
test with a single solution. Each libc++ will be assigned to the
"libc++" category and a single central piece of code will decide whether
we are actually able to run libc++ test in the given configuration by
enabling or disabling the category (while giving the user the
opportunity to override this).

I started this effort because I wanted to get libc++ tests running on
android, and none of the existing decorators worked for this use case:
 - skipIfGcc - incorrect, we can build libc++ executables on android
 with gcc (in fact, after this, we can now do it on linux as well)
 - lldbutil.skip_if_library_missing - this checks whether libc++.so is
 loaded in the proces, which fails in case of a statically linked
 libc++ (this makes copying executables to the remote target easier to
 manage).

To make this work I needed to split out the pseudo_barrier code from the
force-included file, as libc++'s atomic does not play well with gcc on
linux, and this made every test fail, even though we need the code only
in the threading tests.

So far, I am only annotating one of the tests with this category. If
this does not break anything, I'll proceed to update the rest.

r298203 make SBPlatform::MakeDirectory less recursive, which breaks the

I also make the runner complain more loudly when it fails to create the

most of the tests to hang, which is not very helpful in diagnosing the
