Jan Kratochvil 8c82c41262 [lldb] [test] Extend D55859 symbols.enable-external-lookup=false for more testcases
D55859 <https://reviews.llvm.org/D55859> has no effect for some of the
testcases so this patch extends it even for (all?) other testcases known to me.
LLDB was failing when LLDB prints errors reading system debug infos
(`*-debuginfo.rpm`, DWZ-optimized) which should never happen as LLDB testcases
should not be affected by system debug infos.

`lldb/packages/Python/lldbsuite/test/api/multithreaded/driver.cpp.template` is
using only SB API which does not expose `ModuleList` so I had to call
`HandleCommand()` there.

`lldb-test.cpp` could also use `HandleCommand` and then there would be no need
for `ModuleListProperties::SetEnableExternalLookup()` but I think it is cleaner
with API and not on based on text commands.

Jonas Devlieghere 306809f292 [Reproducers] Capture return values of functions returning by ptr/ref
For some reason I had convinced myself that functions returning by
pointer or reference do not require recording their result. However,
after further considering I don't see how that could work, at least not
with the current implementation. Interestingly enough, the reproducer
instrumentation already (mostly) accounts for this, though the
lldb-instr tool did not.

This patch adds the missing macros and updates the lldb-instr tool.

Jan Kratochvil 94b1ff72f5 Sanity check --max-gdbserver-port
In mail
	[lldb-dev] Remote debugging a docker process
	https://lists.llvm.org/pipermail/lldb-dev/2019-March/014795.html
user was confused by --min-gdbserver-port and --max-gdbserver-port options
being ignored. I think there is even a bug that --max-gdbserver-port is upper
exclusive limit (and not upper inclusive limit appropriate for max).

At least this patch should catch such mistake by an error message. The question
is whether --max-gdbserver-port should not be changed to really be max and not
max+1 but that would break backward compatibility.

Now the mail example does produce:
	error: --min-gdbserver-port (5001) is not lower than --max-gdbserver-port (5001)

Add a convenience 'expectedFailureNetBSD' decorator and mark all tests

working.

It seems that there are also some flaky tests.  I am going to address

Zachary Turner 58db03a116 Fix some issues with LLDB's lit configuration files.
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.

Zachary Turner b6355cc561 Refactor the lit configuration files
A year or so ago, I re-wrote most of the lit infrastructure in LLVM so
that it wasn't so boilerplate-y. I added lots of common helper type
stuff, simplifed usage patterns, and made the code more elegant and
maintainable.

We migrated to this in LLVM, clang, and lld's lit files, but not in
LLDBs. This started to bite me recently, as the 4 most recent times I
tried to run the lit test suite in LLDB on a fresh checkout the first
thing that would happen is that python would just start crashing with
unhelpful backtraces and I would have to spend time investigating.

You can reproduce this today by doing a fresh cmake generation, doing
ninja lldb and then python bin/llvm-lit.py -sv ~/lldb/lit/SymbolFile at
which point you'll get a segfault that tells you nothing about what your
problem is.

I started trying to fix the issues with bandaids, but it became clear
that the proper solution was to just bring in the work I did in the rest
of the projects. The side benefit of this is that the lit configuration
files become much cleaner and more understandable as a result.

* This patch fixes hanging of the test in case of using python3, changes callback

* Also, the test didn't work properly since it didn't contain a call of
  filecheck_proc.communicate(), that means that filecheck didn't run and its
  return code was equal to 0 in all cases.

Alexander Polyakov 42be321ca8 [lldb-mi] Fix hanging of target-select-so-path.test
Summary:
The target-select-so-path test might hang on

was in incorrect usage of Filecheck and lldb-mi

to Filecheck, we should run lldb-mi session,
finish the session, collect its output and then pass
it to Filecheck.
Also, this patch adds a timer to the test to prevent
it from hanging in the future.
