Vedant Kumar c56f8ceda8 Revert "[test] Add libLTO as a clang test dependency on Darwin"
This reverts commit r280142. Mehdi suggested a better way to fix up the
test: just create a fake libLTO.dylib and tell the driver where to find
it. Patch incoming...

Vedant Kumar 139756308a [test] Add libLTO as a clang test dependency on Darwin
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.

Samuel Antao 1006ca7176 clang-offload-bundler - offload files bundling/unbundling tool
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.

Justin Bogner 2a15ffa2bf Re-apply "test: Use add_lit_testsuites so that subsets of tests can be specified"
This version should actually remove the empty directories I removed
all of the files from. Thanks to tstellar for pointing out git-svn's
--rmdir flag.

Original message:

This creates make/ninja targets like check-clang-codegen and
check-clang-unit, much like LLVM already has. I had to move some input
files into Input directories so they weren't picked up as test
directories.

Pavel Labath 42f978065b [cmake] Fix builds with LLVM_ENABLE_PIC=0
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.

Teresa Johnson aff223278c [ThinLTO] Option to invoke ThinLTO backend passes and importing
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.

Adrian Prantl e50371b948 Wrap clang modules and pch files in an object file container.
This patch adds ObjectFilePCHContainerOperations uses the LLVM backend
to put the contents of a PCH into a __clangast section inside a COFF, ELF,
or Mach-O object file container.

This is done to facilitate module debugging by makeing it possible to
store the debug info for the types defined by a module alongside the AST.

Adrian Prantl 8bf7af3de8 Wrap clang module files in a Mach-O, ELF, or COFF container.
This is a necessary prerequisite for debugging with modules.
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
dependencies and testcase requirements. Over the last iteration this
version adds
- missing target requirements for testcases that specify an x86 triple,
- a missing clangCodeGen.a dependency to libClang.a in the make build.

Alp Toker 0621cb2e7d Make clang's rewrite engine a core feature
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.

NAKAMURA Takumi e6d79ec0eb [CMake][Standalone] Rewrite standalone build based on llvm-config. CLANG_PATH_TO_LLVM_*(s) are deprecated.
Checked on VS10(multiconfig) and some singleconfig builders.

* Assumptions

  - You should specify llvm-config as LLVM_CONFIG.
    CMake could find one in $PATH by default.

  - ENABLE_ASSERTIONS obeys LLVM's.

* Use cases

  a) With LLVM build tree

    Assume llvm-config is in your build tree.
    Everything should work as ever.

  b) With *installed* LLVM

    Assume distributions. The source tree can be optional.

    b1) The source tree is provided on the location `llvm-config --src-root`

      - Test utils, FileCheck &c., are imported and built in the new tree.
      - Gtest is built in the tree if gtest library is not found.
      - Lit is used in $(SRCROOT)/utils/lit/lit.py.

    b2) The source tree is not provided

      - clang and utilities can be built.
      - All tests, unittests and check-clang are invalidated and not built.
