The core engine of clang-rename will be used for local and global renames in the
new refactoring engine, as mentioned in
http://lists.llvm.org/pipermail/cfe-dev/2017-June/054286.html.
The clang-rename tool is still supported but might get deprecated in the future.

Use the new llvm_canonicalize_cmake_booleans() function to canonicalize
booleans for lit tests. Replace the duplicate ENABLE_CLANG* variables
used to hold canonicalized values with in-place canonicalization. Use
implicit logic in Python code to avoid overrelying on exact 0/1 values.

Recommitted after formal approval.
LLVM's JIT is now the foundation of dynamic-compilation features for many languages. Clang also has low-level support for dynamic compilation (ASTImporter and ExternalASTSource, notably). How the compiler is set up for dynamic parsing is generally left up to individual clients, for example LLDB's C/C++/Objective-C expression parser and the ROOT project.
Although this arrangement offers external clients the flexibility to implement dynamic features as they see fit, the lack of an in-tree client means that subtle bugs can be introduced that cause regressions in the external clients but aren't caught by tests (or users) until much later. LLDB for example regularly encounters complicated ODR violation scenarios where it is not immediately clear who is at fault.
Other external clients (notably, Cling) rely on similar functionality, and another goal is to break this functionality up into composable parts so that any client can be built easily on top of Clang without requiring extensive additional code.
I propose that the parts required to build a simple expression parser be added to Clang. Initially, I aim to have the following features:
A piece that looks up external declarations from a variety of sources (e.g., from previous dynamic compilations, from modules, or from DWARF) and uses clear conflict resolution rules to reconcile differences, with easily understood errors. This functionality will be supported by in-tree tests.
A piece that works hand in hand with the LLVM JIT to resolve the locations of external declarations so that e.g. variables can be redeclared and (for high-performance applications like DTrace) external variables can be accessed directly from the registers where they reside.
This commit adds a tester that parses a sequence of source files and then uses them as source data for an expression. External references are resolved using an ExternalASTSource that responds to name queries using an ASTImporter. This is the setup that LLDB uses, and the motivating reason for MinimalImport in ASTImporter. When complete, this tester will implement the first of the above goals.

Fix the test run to declare missing HAVE_LIBZ value in stand-alone
builds, using the LLVM_ENABLE_ZLIB that is exported in LLVMConfig.cmake.
When using in-tree builds, HAVE_LIBZ is declared in
cmake/config-ix.cmake as a result of LLVM's CMake checks. When building
stand-alone, this value is not available and as a result caused clang to
wrongly assume that LLVM was built without zlib support.
To fix it, set it to the value of LLVM_ENABLE_ZLIB. While this variable
is originally used to control the user preference, LLVM updates its
value to 0 if zlib checks fail. Therefore, we can use it to reliably
determine whether LLVM was built with zlib support or not.

Running 'check-clang' on a stock checkout of llvm+clang doesn't work on
Darwin, because test/Driver/darwin-ld-lto.c can't find libLTO.dylib. Add
libLTO as a clang test dependency on Darwin to fix the problem.
Note: We don't have this issue with check-all because libLTO is in the
test-depends target.

Summary:
One of the goals of programming models that support offloading (e.g. OpenMP) is to enable users to offload with little effort, by annotating the code with a few pragmas. I'd also like to save users the trouble of changing their existent applications' build system. So having the compiler always return a single file instead of one for the host and each target even if the user is doing separate compilation is desirable.
This diff proposes a tool named clang-offload-bundler (happy to change the name if required) that is used to bundle files associated with the same user source file but different targets, or to unbundle a file into separate files associated with different targets.
This tool supports the driver support for OpenMP under review in http://reviews.llvm.org/D9888. The tool is used there to enable separate compilation, so that the very first action on input files that are not source files is a "unbundling action" and the very last non-linking action is a "bundling action".
The format of the bundled files is currently very simple: text formats are concatenated with comments that have a magic string and target identifying triple in between, and binary formats have a header that contains the triple and the offset and size of the code for host and each target.
The goal is to improve this tool in the future to deal with archive files so that each individual file in the archive is properly dealt with. We see that archives are very commonly used in current applications to combine separate compilation results. So I'm convinced users would enjoy this feature.
This tool can be used like this:
`clang-offload-bundler -targets=triple1,triple2 -type=ii -inputs=a.triple1.ii,a.triple2.ii -outputs=a.ii`
or
`clang-offload-bundler -targets=triple1,triple2 -type=ii -outputs=a.triple1.ii,a.triple2.ii -inputs=a.ii -unbundle`
I implemented the tool under clang/tools. Please let me know if something like this should live somewhere else.
This patch is prerequisite for http://reviews.llvm.org/D9888.

Summary:
When this flag is specified, the target llvm-lto is not built, but is still
used as a dependency of the test targets. cmake 2.8 silently ignored this
situation, but with cmake_minimum_required(3.4) it becomes an error. Fix this
by avoiding the inclusion the target as a dependency.

Summary:
Adds new option -fthinlto-index=<file> to invoke the LTO pipeline
along with function importing via clang using the supplied function
summary index file. This supports invoking the parallel ThinLTO
backend processes in a distributed build environment via clang.
Additionally, this causes the module linker to be invoked on the bitcode
file being compiled to perform any necessary promotion and renaming of
locals that are exported via the function summary index file.
Add a couple tests that confirm we get expected errors when we try to
use the new option on a file that isn't bitcode, or specify an invalid
index file. The tests also confirm that we trigger the expected function
import pass.

This patch adds ObjectFilePCHContainerOperations uses the LLVM backend

This is done to facilitate module debugging by makeing it possible to

The .pcm files become containers that hold the serialized AST which allows
us to store debug information in the module file that can be shared by all
object files that were built importing the module.
This reapplies r230044 with a fixed configure+make build and updated

The rewrite facility's footprint is small so it's not worth going to these
lengths to support disabling at configure time, particularly since key compiler
features now depend on it.
Meanwhile the Objective-C rewriters have been moved under the
ENABLE_CLANG_ARCMT umbrella for now as they're comparatively heavy and still
potentially worth excluding from lightweight builds.
Tests are now passing with any combination of feature flags. The flags
historically haven't been tested by LLVM's build servers so caveat emptor.

The tests were correctly getting skipped but the targets still mistakenly got
built.

Performs behind-the-scenes RUN line substitution similarly to what's done with
clang-check and clang-format to ensure the executable is found.

In preparation for using a binary format for instrumentation based
profiling, explicitly treat the test inputs as text and transform them
before running. This will allow us to leave the checked in files in
human readable format once the instrumentation format is binary.
No functional change.

LLVM_*_OUTPUT_INTDIR should be available everywhere. It was my mistake when I introduced INTDIR stuff.
