Andrew Trick 4e67cba8a6 MachineModel: Add a ProcResGroup class.
This allows abitrary groups of processor resources. Using something in
a subset automatically counts againts the superset. Currently, this
only works if the superset is also a ProcResGroup as opposed to a
SuperUnit.

This allows SandyBridge to be expressed naturally, which will be
checked in shortly.

Andrew Trick 3821d9d028 MIsched machine model: tablegen subtarget emitter improvement.
Fix the way resources are counted. I'm taking some time to cleanup the
way MachineScheduler handles in-order machine resources. Eventually
we'll need more PPC/Atom test cases in tree.

Kostya Serebryany cf880b9443 Unify clang/llvm attributes for asan/tsan/msan (LLVM part)
These are two related changes (one in llvm, one in clang).
LLVM: 
- rename address_safety => sanitize_address (the enum value is the same, so we preserve binary compatibility with old bitcode)
- rename thread_safety => sanitize_thread
- rename no_uninitialized_checks -> sanitize_memory

CLANG: 
- add __attribute__((no_sanitize_address)) as a synonym for __attribute__((no_address_safety_analysis))
- add __attribute__((no_sanitize_thread))
- add __attribute__((no_sanitize_memory))

for S in address thread memory
If -fsanitize=S is present and __attribute__((no_sanitize_S)) is not
set llvm attribute sanitize_S

Jim Grosbach 86c652a6b2 Allow targets to add custom asm operand matching logic.
For example, ARM has several instructions with a literal '#0' immediate in the syntax
that's not represented as an actual operand. The asm matcher is expected a token
operand, but the parser will have created an immediate operand. This is currently
handled by dedicated per-instruction C++ munging of the ParsedAsmOperand list, but
will be better handled by this hook.

Bob Wilson 5dba16c581 Preprocess Apple llvmCore headers to reflect NDEBUG setting. <rdar://12568983>
If an Apple llvmCore build is done without assertions, and a client uses
the llvmCore headers with assertions enabled, or vice versa, then things will
break because some of the structure sizes in the API are different.  Use the
unifdef tool to make the headers unconditionally match the way the llvmCore
libraries were built.

Jack Carter 9c1a027fe8 This patch that sets the EmitAlias flag in td files
and enables the instruction printer to print aliased 
instructions. 

Due to usage of RegisterOperands a change in common 
code (utils/TableGen/AsmWriterEmitter.cpp) is required 
to get the correct register value if it is a RegisterOperand.

Tim Northover e0e3aefdd3 Add AArch64 as an experimental target.
This patch adds support for AArch64 (ARM's 64-bit architecture) to
LLVM in the "experimental" category. Currently, it won't be built
unless requested explicitly.

This initial commit should have support for:
    + Assembly of all scalar (i.e. non-NEON, non-Crypto) instructions
      (except the late addition CRC instructions).
    + CodeGen features required for C++03 and C99.
    + Compilation for the "small" memory model: code+static data <
      4GB.
    + Absolute and position-independent code.
    + GNU-style (i.e. "__thread") TLS.
    + Debugging information.

The principal omission, currently, is performance tuning.

This patch excludes the NEON support also reviewed due to an outbreak of
batshit insanity in our legal department. That will be committed soon bringing
the changes to precisely what has been approved.

Further reviews would be gratefully received.

NAKAMURA Takumi 61a8f974a7 [CMake][Lit][unittests] Deprecate CMAKE_BUILD_TYPE in each build directory for unittests.
For example,
cur) unittests/ADT/Release/ADTTests
new) unittests/ADT/ADTTests

RUNTIME_BUILD_MODE can be substituted to CMAKE_CFG_INTDIR.

With Make and Ninja, the tree is not built with multiple configurations.
Then, including the build type in target directory doesn't make sense.
See also "How can I build multiple modes without switching?"
http://www.cmake.org/Wiki/CMake_FAQ
CMAKE_CFG_INTDIR is set to "."

With multiple-configuration-aware build system, like Visual Studio, each unittest is built on appropriate directory, for example,
unittests/ADT/Release/ADTTests.exe
CMAKE_CFG_INTDIR is set to build system's variable, like "$(Configuration)" or "$(OutDir)".

Thus, "--param build_config" is also deprecated.

Bill Wendling d154e283f2 Add the IR attribute 'sspstrong'.
SSPStrong applies a heuristic to insert stack protectors in these situations:

* A Protector is required for functions which contain an array, regardless of
  type or length.

* A Protector is required for functions which contain a structure/union which
  contains an array, regardless of type or length.  Note, there is no limit to
  the depth of nesting.

* A protector is required when the address of a local variable (i.e., stack
  based variable) is exposed. (E.g., such as through a local whose address is
  taken as part of the RHS of an assignment or a local whose address is taken as
  part of a function argument.)

This patch implements the SSPString attribute to be equivalent to
SSPRequired. This will change in a subsequent patch.
