Alex Langford 72cb10c364 Modify lldb_suite.py to enable python debugging
Summary:
pudb and pdb interfere with the behavior of the inspect module. calling
`inspect.getfile(inspect.currentframe())` returns a different result
depending on whether or not you're in a debugger. Calling
`os.path.abspath` on the result of `inspect.getfile(...)` normalizes the
result between the two environments.

Jonas Devlieghere 60cbbb4440 [CMake] Move some variables around
This improves consistency by creating a CMake variable for the dsymutil
path. The motivation is that for Swift, the dsymutil binary and the lldb
binary live in different directories and we need an option to configure
this from the build script.

Jonas Devlieghere 52721286b2 [CMake] Unify and relayer testing
This patch restructures part of LLDB's testing configuration:

1. I moved the test dependencies up the chain so every dotest dependency
   becomes a lit dependency as well. It wouldn't make sense for dotest to
   have other dependencies when it's being run by lit. Lit on the other
   hand can still specify extra dependencies.

2. I replaced as much generator expressions with variables as possible.
   This is consistent with the rest of LLVM and doesn't break generators
   that support multiple targets (MSVC, Xcode). This wasn't a problem
   before, but now we need to expand the dotest arguments in the lit
   configuration and there's only one test suite even with multiple
   targets.

3. I moved lldb-dotest into it's own directory under utils since there's
   no need anymore for it to located under `test/`.

Jonas Devlieghere 49f4aee0e3 [lit] Generate a single lit cfg file for tests that require dotest.py
The current way that the lit configuration is generated for the LLDB
tests that run using dotest causes cmake to fail when using a generator
which supports multiple configurations (such as Visual Studio). The
failure is because file GENERATE will create a file *per possible
configuration* resulting in the same lit configuration file being
overwritten multiple times.

To fix the issue, we need to create a single lit file that is agnostic
of the configurations and can be used for any configuration.

Jonas Devlieghere 1a928f3fc7 [LIT] Have lit run the lldb test suite
This is the first in what will hopefully become a series of patches to
replace the driver logic in dotest.py with LIT. The motivation for this
change is that there's no point in maintaining two driver
implementations. Since all of the LLVM projects are using lit, this is
the obvious choice.

Obviously the goal is maintain full compatibility with the functionality
offered by dotest. As such we won't be removing anything until that
point has been reached.

This patch is the initial attempt (referred to as v1) to run the lldb
test suite with lit. To do so we introduced a custom LLDB test format
that invokes dotest.py with a single test file.

Summary:

This will also allow us to re-enable TestUnicodeSymbols which was
failing because of the discrepancy in how Unicode symbols were hashed in
lldb and older versions of dsymutil.

Pavel Labath 63047d05c0 [dotest] Clean up test folder clean-up
Summary:
This patch implements a unified way of cleaning the build folder of each
test. This is done by completely removing the build folder before each
test, in the respective setUp() method. Previously, we were using a
combination of several methods, each with it's own drawbacks:
- nuking the entire build tree before running dotest: the issue here is
  that this did not take place if you ran dotest manually
- running "make clean" before the main "make" target: this relied on the
  clean command being correctly implemented. This was usually true, but
  not always.
- for files which were not produced by make, each python file was
  responsible for ensuring their deleting, using a variety of methods.

With this approach, the previous methods become redundant. I remove the
first two, since they are centralized. For the other various bits of
clean-up code in python files, I indend to delete it when I come
across it.

Vedant Kumar 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:

$ ./bin/llvm-dotest -p TestRegisters.py -v
  1 out of 617 test suites processed - TestRegisters.py

Jonas Devlieghere a52cb80db6 [test] Add dotest wrapper
This adds a wrapper around dotest, similar to llvm-lit in llvm. The
wrapper is created in the binary directory, next to LLDB and allows you
to invoke dotest without having to pass any of the configuration
arguments yourself. I think this could also be useful for re-running a
particular test case when it fails, as an alternative to "Command
Invoked".

The motivation for this is that I'd like to replace the driver part of
dotest with lit. As a first step, I'd like to have lit invoke dotest,
which would just run the complete test suite, completely identical to
what the CMake target does today. Once this is in place, we can have lit
run dotest for the different test directories, and ultimately once per
python file. Along the way we can strip out driver functionality from
dotest where appropriate.

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.

- Utility functions for handling common data encoding/decoding
- Utility functions for creating dummy targets from YAML files

On Darwin, if a test machine isn't set up for code-signing (see

Summary:
Using the in-tree clang should be the default test configuration as that
is the one compiler that we can be sure everyone has (better
reproducibility of test results). Also, it should hopefully reduce the
impact of pr35040.

This also reduces the number of settings which control the compiler
used. LLDB_TEST_C_COMPILER is used for C files and
LLDB_TEST_CXX_COMPILER for C++ files. Both of the settings default to
the in-tree clang.

*** to conform to clang-format’s LLVM style.  This kind of mass change has
*** two obvious implications:

Firstly, merging this particular commit into a downstream fork may be a huge
effort.  Alternatively, it may be worth merging all changes up to this commit,
performing the same reformatting operation locally, and then discarding the
merge for this particular commit.  The commands used to accomplish this
reformatting were as follows (with current working directory as the root of
the repository):

    find . \( -iname "*.c" -or -iname "*.cpp" -or -iname "*.h" -or -iname "*.mm" \) -exec clang-format -i {} +
    find . -iname "*.py" -exec autopep8 --in-place --aggressive --aggressive {} + ;

The version of clang-format used was 3.9.0, and autopep8 was 1.2.4.

Secondly, “blame” style tools will generally point to this commit instead of
a meaningful prior commit.  There are alternatives available that will attempt
to look through this change and find the appropriate prior commit.  YMMV.
