Move the logic for determining the `wchar_t` type information into the
driver. Rather than passing the single bit of information of
`-fshort-wchar` indicate to the frontend the desired type of `wchar_t`
through a new `-cc1` option of `-fwchar-type` and indicate the
signedness through `-f{,no-}signed-wchar`. This replicates the current
logic which was spread throughout Basic into the
`RenderCharacterOptions`.
Most of the changes to the tests are to ensure that the frontend uses
the correct type. Add a new test set under `test/Driver/wchar_t.c` to
ensure that we calculate the proper types for the various cases.

to support operator keywords used in Windows SDK, alter token type when
seen in system headers
Hello, I submitted D33505 to address this problem, but the
proposal was rejected as too big a hammer.
This change will allow clang to parse the WindowsSDK header <query.h>
which uses the operator name "or" as a field name. Treat cpp operator
keywords as ordinary identifiers inside the Microsoft headers, but
treat them as usual in the user's program.

size_t is usually defined as unsigned long, but on 64-bit platforms,
stdint.h currently defines SIZE_MAX using "ull" (unsigned long long).
Although this is the same width, it doesn't necessarily have the same
alignment or calling convention. It also triggers printf warnings when
using the format flag "%zu" to print SIZE_MAX.
This changes SIZE_MAX to reuse the compiler-provided __SIZE_MAX__, and
provides similar fixes for the other integers:
- INTPTR_MIN
- INTPTR_MAX
- UINTPTR_MAX
- PTRDIFF_MIN
- PTRDIFF_MAX
- INTMAX_MIN
- INTMAX_MAX
- UINTMAX_MAX
- INTMAX_C()
- UINTMAX_C()
... and fixes the typedefs for intptr_t and uintptr_t to use
__INTPTR_TYPE__ and __UINTPTR_TYPE__ instead of int32_t, effectively
reverting r89224, r89226, and r89237 (r89221 already having been
effectively reverted).
We can probably also kill __INTPTR_WIDTH__, __INTMAX_WIDTH__, and
__UINTMAX_WIDTH__ in a follow-up, but I was hesitant to delete all the
per-target CHECK lines in this commit since those might serve their own
purpose.

This fixes compiling with headers from the Windows SDK for ARM, where the
YieldProcessor function (in winnt.h) refers to _ARM_BARRIER_ISHST.
The actual MSVC armintr.h contains a lot more definitions, but this is enough to
build code that uses the Windows SDK but doesn't use ARM intrinsics directly.
An alternative would to just keep the addition to intrin.h (to include
armintr.h), but not actually ship armintr.h, instead having clang's intrin.h
include armintr.h from MSVC's include directory. (That one works fine with
clang, at least for building code that uses the Windows SDK.)

Before, clang's internal assembler would reject the inline asm in clang's
Intrin.h. To make sure this doesn't happen for other Intrin.h functions using
__asm__ blocks, add 32-bit and 64-bit codegen tests for Intrin.h.
Sadly, these tests discovered that __readcr3 and __writecr3 have bad
implementations in 64-bit builds. This will have to be fixed in a follow-up.

This involved removing the conditional inclusion and replacing them
with target attributes matching the original conditional inclusion
and checks. The testcase update removes the macro checks for each
file and replaces them with usage of the __target__ attribute, e.g.:
int __attribute__((__target__(("sse3")))) foo(int a) {
_mm_mwait(0, 0);
return 4;
}
This usage does require the enclosing function have the requisite
__target__ attribute for inlining and code generation - also for
any macro intrinsic uses in the enclosing function. There's no change
for existing uses of the intrinsic headers.

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.

Clang has introduced ::max_align_t in stddef.h in r201729, but libc++ was
already defining std::max_align_t on Darwin because there was none in the
global namespace. After that Clang commit though, libc++ started defining
std::max_align_t to be a typedef for ::max_align_t, which has a different
definition. This changed the ABI. This commit restores the previous
definition.

This patch adds builtin support for xvdivdp and xvdivsp, along with a

llvm-svn: 221984
The use of the vec_lvsl and vec_lvsr interfaces are discouraged for
little endian targets since Power8 hardware is a minimum requirement,
and Power8 provides reasonable performance for unaligned vector loads
and stores. Up till now we have not provided "correct" (i.e., big-
endian-compatible) code generation for these interfaces, as to do so
produces poorly performing code. However, this has become the source
of too many questions.
With this patch, LLVM will now produce compatible code for these
interfaces, but will also produce a deprecation warning message for
PPC64LE when one of them is used. This should make the porting direction
clearer to programmers. A similar patch has recently been committed to
GCC.
This patch includes a test for the warning message. There is a companion
patch that adds two unit tests to projects/test-suite.

When building with modules enabled, we were defining max_align_t as a typedef

This commit makes two changes:
- Remove the push and pop instructions that were saving and restoring %ebx
before and after cpuid in 32-bit pic mode. We were doing this to ensure we
don't lose the GOT address in pic register %ebx, but this isn't necessary
because the GOT address is kept in a virtual register.
- In 64-bit mode, preserve base register %rbx around cpuid.
This fixes PR20311 and rdar://problem/17686779.

This restores the original behaviour of -fmsc-version. The older option
remains as a mechanism for specifying the basic version information. A
secondary option, -fms-compatibility-version permits the user to specify an
extended version to the driver.
The new version takes the value as a dot-separated value rather than the
major * 100 + minor format that -fmsc-version format. This makes it easier to
specify the value as well as a more flexible manner for specifying the value.
Specifying both values is considered an error.
The older parameter is left solely as a driver option, which is normalised into
the newer parameter. This allows us to retain a single code path in the
compiler itself whilst preserving the semantics of the old parameter as well as
avoid having to determine which of two formats are being used by the invocation.
The test changes are due to the fact that the compiler no longer supports the
old option, and is a direct conversion to the new option.

This adds the ARM ACLE hint intrinsic wrappers to arm_acle.h. These need to be
