Use llvm_codesign to sign debugserver with entitlements.
Set global LLVM_CODESIGNING_IDENTITY from LLDB_CODESIGN_IDENTITY (if given).
Pass through ENTITLEMENTS from add_lldb_executable to add_llvm_executable.
Handle reconfigurations correctly.
We have a lot of cases, make them explicit:

* LLDB_NO_DEBUGSERVER=OFF (default)
* On Darwin: LLDB_USE_SYSTEM_DEBUGSERVER=OFF (default)
* On Darwin: LLVM_CODESIGNING_IDENTITY == lldb_codesign
(2) use system debugserver, if on Darwin and any of:
* LLDB_USE_SYSTEM_DEBUGSERVER=ON and found on system (explicit case)
* LLVM_CODESIGNING_IDENTITY != lldb_codesign and found on system (fallback case)
(3) debugserver will not be available, in case of:
* LLDB_NO_DEBUGSERVER=ON
* On Darwin: LLVM_CODESIGNING_IDENTITY != lldb_codesign and not found on system
(4) error state, in case of:
* LLDB_USE_SYSTEM_DEBUGSERVER=ON and not found on system
* LLDB_USE_SYSTEM_DEBUGSERVER=ON and LLDB_NO_DEBUGSERVER=ON

Recently I tried to port LLDB's lit configuration files over to use a
on the surface, but broke some cases that weren't broken before and also
exposed some additional problems with the old approach that we were just
getting lucky with.
When we set up a lit environment, the goal is to make it as hermetic as
possible. We should not be relying on PATH and enabling the use of
arbitrary shell commands. Instead, only whitelisted commands should be
allowed. These are, generally speaking, the lit builtins such as echo,
cd, etc, as well as anything for which substitutions have been
explicitly set up for. These substitutions should map to the build
output directory, but in some cases it's useful to be able to override
this (for example to point to an installed tools directory).
This is, of course, how it's supposed to work. What was actually
happening is that we were bringing in PATH and LD_LIBRARY_PATH and then
just running the given run line as a shell command. This led to problems
such as finding the wrong version of clang-cl on PATH since it wasn't
even a substitution, and flakiness / non-determinism since the
environment the tests were running in would change per-machine. On the
other hand, it also made other things possible. For example, we had some
tests that were explicitly running cl.exe and link.exe instead of
clang-cl and lld-link and the only reason it worked at all is because it
was finding them on PATH. Unfortunately we can't entirely get rid of
these tests, because they support a few things in debug info that
clang-cl and lld-link don't (notably, the LF_UDT_MOD_SRC_LINE record
which makes some of the tests fail.
The high level changes introduced in this patch are:
1. Removal of functionality - The lit test suite no longer respects
LLDB_TEST_C_COMPILER and LLDB_TEST_CXX_COMPILER. This means there is no
more support for gcc, but nobody was using this anyway (note: The
functionality is still there for the dotest suite, just not the lit test
suite). There is no longer a single substitution %cxx and %cc which maps
to <arbitrary-compiler>, you now explicitly specify the compiler with a
substitution like %clang or %clangxx or %clang_cl. We can revisit this
in the future when someone needs gcc.
2. Introduction of the LLDB_LIT_TOOLS_DIR directory. This does in spirit
what LLDB_TEST_C_COMPILER and LLDB_TEST_CXX_COMPILER used to do, but now
more friendly. If this is not specified, all tools are expected to be
the just-built tools. If it is specified, the tools which are not
themselves being tested but are being used to construct and run checks
(e.g. clang, FileCheck, llvm-mc, etc) will be searched for in this
directory first, then the build output directory.
3. Changes to core llvm lit files. The use_lld() and use_clang()
functions were introduced long ago in anticipation of using them in
lldb, but since they were never actually used anywhere but their
respective problems, there were some issues to be resolved regarding
generality and ability to use them outside their project.
4. Changes to .test files - These are all just replacing things like
clang-cl with %clang_cl and %cxx with %clangxx, etc.
5. Changes to lit.cfg.py - Previously we would load up some system
environment variables and then add some new things to them. Then do a
bunch of work building out our own substitutions. First, we delete the
system environment variable code, making the environment hermetic. Then,
we refactor the substitution logic into two separate helper functions,
one which sets up substitutions for the tools we want to test (which
must come from the build output directory), and another which sets up
substitutions for support tools (like compilers, etc).
6. New substitutions for MSVC -- Previously we relied on location of
MSVC by bringing in the entire parent's PATH and letting
subprocess.Popen just run the command line. Now we set up real
substitutions that should have the same effect. We use PATH to find
them, and then look for INCLUDE and LIB to construct a substitution
command line with appropriate /I and /LIBPATH: arguments. The nice thing
about this is that it opens the door to having separate %msvc-cl32 and
%msvc-cl64 substitutions, rather than only requiring the user to run
vcvars first. Because we can deduce the path to 32-bit libraries from
64-bit library directories, and vice versa. Without these substitutions
this would have been impossible.

Add a "filecheck" method to the LLDB test base. This allows test authors
to pattern match command output using FileCheck, making it possible to
write stricter tests than what `self.expect` allows.
For context (motivation, examples of stricter checking, etc), see the
lldb-dev thread: "Using FileCheck in lldb inline tests".

This improves consistency by creating a CMake variable for the dsymutil

The framework argument was broken when I removed the generator

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/`.

The lit site configuration for the test suite can contain generator
expressions such as $<TARGET_FILE:debugserver> that need to be
substituted.
llvm-svn: 331277
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.

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.

With the upstream implementation of dsymutil containing almost all

This will also allow us to re-enable TestUnicodeSymbols which was

lldb and older versions of dsymutil.

If we don't wrap arguments to the wrapper in single quotes, combined

separate arguments, causing the latter to fail.
llvm-svn: 328020
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.

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:

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.

Also, fix a missing dependency, as lit requires llvm-config
to run. This is becoming more and more important as we

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.

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

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

CMake's framework target generation was unable to generate POST_BUILD steps (see: https://gitlab.kitware.com/cmake/cmake/issues/16363).
It turns out working around this is really not reasonable. The more reasonable solution to me is just to not support LLDB.framework unless you are on CMake 3.7 or newer.
Since CMake 3.7.1 is released that's how I'm going to handle this.

This ensures that the Resources and clang headers are properly symlinked in LLDB's framework. This should fix the modules-related tests when building on Darwin with CMake if you are building a framework.

dotest.py has a framework option that is not respected. This patch makes the framework path properly configurable via the --framework option.
This patch also adds a function to the lldbtest.Base class named "hasDarwinFramework" which allows us to not rely on the host platform to determine if a framework is present. If running on Darwin, and not building a framework, this will follow the *nix code paths which are appropriate for Darwin.

*** 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.
