Ilya Biryukov da0bf49b45 [Tooling] Restore working dir in ClangTool.
Summary:
And add an option to disable this behavior. The option is only used in
AllTUsExecutor to avoid races when running concurrently on multiple
threads.

This fixes PR38869 introduced by r340937.

Ilya Biryukov 6509b6d9b6 [Tooling] Do not restore working dir in ClangTool
Summary:
Resolve all relative paths before running the tool instead.

This fixes the usage of ClangTool in AllTUsExecutor. The executor will
try running multiple ClangTool instances in parallel with compile
commands that usually have the same working directory.

Changing working directory is a global operation, so we end up
changing working directory in the middle of running other actions,
which leads to spurious compile errors.

Nicola Zaghen ff0626ea3c [clang] Update uses of DEBUG macro to LLVM_DEBUG.
The DEBUG() macro is very generic so it might clash with other projects.
The renaming was done as follows:
- git grep -l 'DEBUG' | xargs sed -i 's/\bDEBUG\s\?(/LLVM_DEBUG(/g'
- git diff -U0 master | ../clang/tools/clang-format/clang-format-diff.py -i -p1 -style LLVM

Explicitly avoided changing the strings in the clang-format tests.

This is similar to the LLVM change https://reviews.llvm.org/D46290.

We've been running doxygen with the autobrief option for a couple of
years now. This makes the \brief markers into our comments
redundant. Since they are a visual distraction and we don't want to
encourage more \brief markers in new code either, this patch removes
them all.

Summary:
Noticed during review of D41102.

I'm not sure whether there are any principal reasons why it returns raw owning pointer,
or it is just a old code that was not updated post-C++11.

I'm not too sure what testing i should do, because `check-all` is not error clean here for some reason,
but it does not //appear// asif those failures are related to these changes.

This is clang part.
Clang-tools-extra part is D43780.

Eric Liu e7a10639e3 [Tooling] A new framework for executing clang frontend actions.
Summary:
This defines a `clang::tooling::ToolExecutor` interface that can be extended to support different execution plans including standalone execution on a given set of TUs or parallel execution on all TUs in a codebase.

In order to enable multiprocessing execution, tool actions are expected to output result into a `ToolResults` interface provided by executors. The `ToolResults` interface abstracts how results are stored e.g. in-memory for standalone executions or on-disk for large-scale execution.

New executors can be registered as `ToolExecutorPlugin`s via the `ToolExecutorPluginRegistry`. CLI tools can use `createExecutorFromCommandLineArgs` to create a specific registered executor according to the command-line arguments.

This patch also implements `StandaloneToolExecutor` which has the same behavior as the current `ClangTool` interface, i.e. execute frontend actions on a given set of TUs. At this point, it's simply a wrapper around `ClangTool` at this point.

This is still experimental but expected to replace the existing `ClangTool` interface so that specific tools would not need to worry about execution.

Sterling Augustine 2b311bba46 Allow CompilerInvocations to generate .d files.
Summary:
Most clang tools should ignore the -M
family of options because one wouldn't want them
to generate a new dependency (.d) file. However,
some tools may want this dependency file. This
patch creates a mechanism for them to do this.

This implementation just plumbs a boolean down
several layers of calls. Each of the modified calls
has several call sites, and so a single member
variable or new API entry point won't work.

An alternative would be to write a function to filter
the -M family of arguments out of CC1Args, and have
each caller call that function by hand before calling
newInvocation, Invocation::run, or buildAstFromCodeWithArgs.
This is a more complicated and error-prone solution.
Why burden all the callers to remember to use
this function?

But I could rewrite this patch to use that method if
that is deemed more appropriate.

a block for implementing D33013, because after that change driver will
refuse to create compilation if command line contains erroneous options.

This change adds additional argument to loadFromCommandLine, which is
assigned error message text if compilation object was not created. This is
the same way as other methods of CompilationDatabase report failure.

Manuel Klimek 0d0de1222f Adds a way for tools to deduce the target config from a compiler name.
Adds `addTargetAndModeForProgramName`, a utility function that will add
appropriate `-target foo` and `--driver-mode=g++` tokens to a command
line for driver invocations of the form `a/b/foo-g++`. It is intended to
support tooling: for example, should a compilation database record some
invocation of `foo-g++` without these implicit flags, a Clang tool may
use this function to add them back.

Adrian Prantl 5f4be954a1 Introduce a PCHContainerOperations interface (NFC).
A PCHContainerOperations abstract interface provides operations for
creating and unwrapping containers for serialized ASTs (precompiled
headers and clang modules). The default implementation is
RawPCHContainerOperations, which uses a flat file for the output.

The main application for this interface will be an
ObjectFilePCHContainerOperations implementation that uses LLVM to
wrap the module in an ELF/Mach-O/COFF container to store debug info
alongside the AST.

Manuel Klimek b3cf7e2fbf Re-apply r222646 (was reverted in r222667). Adding 4 ASTMatchers: typedefDecl, isInMainFile, isInSystemFile, isInFileMatchingName
Change to original: ifndef out tests in Windows due to /-separated
paths.

Summary:
Often one is only interested in matches within the main-file or matches
that are not within a system-header, for which this patch adds
isInMainFile and isInSystemFile. They take no arguments and narrow down
the matches.

The isInFileMatchingName is mainly thought for interactive
clang-query-sessions, to make a matcher more specific without restarting
the session with the files you are interested in for that moment. It
takes a string that will be used as regular-expression to match the
filename of where the matched node is expanded.

Patch by Hendrik von Prince.

Alexander Kornienko ffbc78615c [Tooling] Restore current directory after processing each file.
Summary:
If we actually change directory before processing a file, we need to
restore it afterwards. This was broken in r216620.

Added a comment for the changes in r216620.

Justin Bogner 6597883c1e Driver: Use pointee_iterator rather than iterating over unique_ptrs
There's probably never a good reason to iterate over unique_ptrs. This
lets us use range-for and say Job.foo instead of (*it)->foo in a few
places.
