-Patches commit r241343: case 'armv7l' was unhandled in
ARMTargetInfo::getCPUAttr(), and thus it was returning invalid
characters for macro definition.

MSVC 4.2 didn't have bool as a builtin type but MSVC 5.0 does. When
they added it, they added a macro (__BOOL_DEFINED) which allows build
scripts and the like to know if they should provide their own bool.
Clang always supports bool as a builtin type in C++ mode.

For Mips direct-to-nacl, the goal is to be close to le32 front-end and
use Mips32EL backend. This patch defines new NaClMips32ELTargetInfo and
modifies it slightly to be close to le32. It also adds necessary parts,
inline with ARM and X86.

- Patch for commit 241267: ShouldUseInlineAtomic was set incorrectly when subArch was
not specified, causing regressions.

This reinstates part of the hack removed in r233223, by special
casing sse4 as part of the feature additions. The notable change
here is that we consider it only as part of setting the SSE level
and not as part of the actual target features set which handles
setting the rest of the masks.

This matches the implementation of the gcc support for the same
feature, including checking the values set up by libgcc at runtime.
The structure looks like this:
unsigned int __cpu_vendor;
unsigned int __cpu_type;
unsigned int __cpu_subtype;
unsigned int __cpu_features[1];
with a set of enums to match various fields that are field out after
parsing the output of the cpuid instruction.
This also adds a set of errors checking for valid input (and cpu).
compiler-rt support for this and the other builtins in this family
(__builtin_cpu_init and __builtin_cpu_is) are forthcoming.

when iterating through the Features vector if we don't
keep track of what's already been set. This could lead to
the macro __ARM_FP getting the wrong value. This patch
fixes this issue by keeping track of the bits that have
already been set in the loop.

As specified in the SysV AVX512 ABI drafts. It follows the same scheme
as AVX2:
Arguments of type __m512 are split into eight eightbyte chunks.
The least significant one belongs to class SSE and all the others
to class SSEUP.
This also means we change the OpenMP SIMD default alignment on AVX512.
Based on r240337.

In r239421, the mangling of long double on PowerPC Linux targets
was changed to use "g" instead of "e". This same change also needs
to be done for SystemZ (all targets, since we support only Linux
on SystemZ anyway).
This is because an old ABI variant set "long double" to a 64-bit
type equivalent to "double", and the "e" mangling code is still
used to refer to that old ABI for compatibility reasons.

Some people want to experiment with building i686 CloudABI binaries. I
am not entirely sure this is a good idea, as I'd rather see Intel x32
support appear.
As it only requires a two-line change, let's at least provide compiler
to ease experimenting.

GCC mangles long double like __float128 in order to support
compatibility with ABI variants which had a different interpretation of
long double.
This fixes PR23791.

They should be 'int' instead of 'long int' everywhere else except
NetBSD too, from what I gather in GCC's spec files. So, optimistically
changing it for everyone else, too.

Cygwin (and MinGW) targets define __declspec to __attribute__ unless
-fms-extensions is specified. It turns out that cygwin headers rely on
the existence of this macro.

Avoiding ugly combination of string parsing in the front-end. We still
need to move away from CPU parsing at all, but that's for a different
commit.

This patch adds support for the following new instructions in the
Power ISA 2.07:
vpksdss
vpksdus
vpkudus
vpkudum
vupkhsw
vupklsw
These instructions are available through the vec_packs, vec_packsu,
vec_unpackh, and vec_unpackl built-in interfaces. These are
lane-sensitive instructions, so the built-ins have different
implementations for big- and little-endian, and the instructions must
be marked as killing the vector swap optimization for now.
The first three instructions perform saturating pack operations. The
fourth performs a modulo pack operation, which means it can be
represented with a vector shuffle, and conversely the appropriate
vector shuffles may cause this instruction to be generated. The other
instructions are only generated via built-in support for now.
I noticed during patch preparation that the macro __VSX__ was not
previously predefined when the power8-vector or direct-move features
are requested. This is an error, and I've corrected that here as
well.
Appropriate tests have been added.
There is a companion patch to llvm for the rest of this support.

Follow-up to commit for revision 236848.
Just a test case for the macro definition under the right CPU/Arch.
One combination was actually missed in the initial fix:
- powerpc64-unknown-unknown -mcpu=pwr8 (rather than -mcpu=power8).
llvm-svn: 237386
This patch adds support for the z13 architecture type. For compatibility
with GCC, a pair of options -mvx / -mno-vx can be used to selectively
enable/disable use of the vector facility.
When the vector facility is present, we default to the new vector ABI.
This is characterized by two major differences:
- Vector types are passed/returned in vector registers
(except for unnamed arguments of a variable-argument list function).
- Vector types are at most 8-byte aligned.
The reason for the choice of 8-byte vector alignment is that the hardware
is able to efficiently load vectors at 8-byte alignment, and the ABI only
guarantees 8-byte alignment of the stack pointer, so requiring any higher
alignment for vectors would require dynamic stack re-alignment code.
However, for compatibility with old code that may use vector types, when
*not* using the vector facility, the old alignment rules (vector types
are naturally aligned) remain in use.
These alignment rules are not only implemented at the C language level,
but also at the LLVM IR level. This is done by selecting a different
DataLayout string depending on whether the vector ABI is in effect or not.
Based on a patch by Richard Sandiford.

Cyclone actually supports all the goodies you'd expect to come with an AArch64
CPU, so it doesn't need its own clause. Also we should probably be testing
these clauses.
