Teresa Johnson 9e3f4746d5 CodeGen: Replace ThinLTO backend implementation with a client of LTO/Resolution.
Summary:
This changes clang to use the llvm::lto::thinBackend function instead of
its own less comprehensive ThinLTO backend implementation.

Samuel Antao 3f465c095b [OpenMP] Reorganize code to allow specialized code generation for different devices.
Summary:
Different devices may in some cases require different code generation schemes in order to implement OpenMP. This is required not only for performance reasons, but also because it may not be possible to have the current (default) implementation working for these devices. E.g. GPU's cannot implement the same scheme a target such as powerpc or x86b would use, in the sense that it does not have the ability to fork threads, instead all the threads are always executing and need to be managed by the implementation. 

This patch proposes a reorganization of the code in the OpenMP code generation to pave the way to have specialized implementation of OpenMP support. More than a "real" patch this is more a request for comments in order to understand if what is proposed is acceptable or if there are better/easier ways to do it.

In this patch part of the common OpenMP codegen infrastructure is moved to a new file under a new namespace (CGOpenMPCommon) so it can be shared between the default implementation and the specialized one. When CGOpenMPRuntime is created, an attempt to select a specialized implementation is done.

In the patch a specialization for nvptx targets is done which currently checks if the target is an OpenMP device and trap if it is not. 

Let me know comments suggestions you may have.

Justin Lebar 3039a593db [CUDA] Make printf work.
Summary:
The code in CGCUDACall is largely based on a patch written by Eli
Bendersky:
http://lists.llvm.org/pipermail/llvm-commits/Week-of-Mon-20140324/210218.html

That patch implemented an LLVM pass lowering printf to vprintf; this
one does something similar, but in Clang codegen.

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.

Alexey Samsonov 8d043e82ef Move SanitizerBlacklist to clangBasic. NFC.
This change moves SanitizerBlacklist.h from lib/CodeGen
to public Clang headers in include/clang/Basic. SanitizerBlacklist
is currently only used in CodeGen to decide which functions/modules
should be instrumented, but this will soon change as ASan will
optionally modify class layouts during AST construction
(http://reviews.llvm.org/D5687). We need blacklist machinery
to be available at this point.

Alexey Samsonov 4b8de11c81 [Sanitizer] Introduce SanitizerMetadata class.
It is responsible for generating metadata consumed by sanitizer instrumentation
passes in the backend. Move several methods from CodeGenModule to SanitizerMetadata.
For now the class is stateless, but soon it won't be the case.

Instead of creating globals providing source-level information to ASan, we will create
metadata nodes/strings which will be turned into actual global variables in the
backend (if needed).

No functionality change.

Alexey Samsonov b7dd329f2f Decouple llvm::SpecialCaseList text representation and its LLVM IR semantics.
Turn llvm::SpecialCaseList into a simple class that parses text files in
a specified format and knows nothing about LLVM IR. Move this class into
LLVMSupport library. Implement two users of this class:
  * DFSanABIList in DFSan instrumentation pass.
  * SanitizerBlacklist in Clang CodeGen library.
The latter will be modified to use actual source-level information from frontend
(source file names) instead of unstable LLVM IR things (LLVM Module identifier).

Remove dependency edge from ClangCodeGen/ClangDriver to LLVMTransformUtils.

No functionality change.

David Majnemer e2cb8d198f CodeGen: Refactor RTTI emission
Let's not expose ABI specific minutia inside of CodeGenModule and Type.
Instead, let's abstract it through CXXABI.

This gets rid of:
CodeGenModule::getCompleteObjectLocator,
CodeGenModule::EmitFundamentalTypeDescriptor{s,},
CodeGenModule::getMSTypeDescriptor,
CodeGenModule::getMSCompleteObjectLocator,
CGCXXABI::shouldRTTIBeUnique,
CGCXXABI::classifyRTTIUniqueness.

CGRTTI was *almost* entirely centered around providing Itanium-style
RTTI information.  Instead of providing interfaces that only it
consumes, move it to the ItaniumCXXABI implementation file.  This allows
it to have access to Itanium-specific implementation details without
providing useless expansion points for the Microsoft ABI side.

NAKAMURA Takumi 7da9487dd4 [CMake] Get rid of explicit dependencies to include/clang/*.inc and introduce CLANG_TABLEGEN_TARGETS.
This does;
  - clang_tablegen() adds each tblgen'd target to global property CLANG_TABLEGEN_TARGETS as list.
  - List of targets is added to LLVM_COMMON_DEPENDS.
  - all clang libraries and targets depend on generated headers.

You might wonder this would be regression, but in fact, this is little loss.
  - Almost all of clang libraries depend on tblgen'd files and clang-tblgen.
  - clang-tblgen may cause short stall-out but doesn't cause unconditional rebuild.
  - Each library's dependencies to tblgen'd files might vary along headers' structure.
    It made hard to track and update *really optimal* dependencies.

Each dependency to intrinsics_gen and ClangSACheckers is left as DEPENDS.

Summary:
No functionality change.

This code should live here long-term because we should be able to use it
to compute correct vftable names.

It turns out that the most natural way to implement the naming algorithm
is to use a caching layer similar to what we already have for virtual
table info in VTableContext.  Subsequent changes will take advantage of
this to fix PR17748, where we have a vbtable name collision.
