GCC will interpret `__attribute__((__aligned__))` as 8-byte alignment on
ARM, but clang will not. Explicitly specify the alignment. This
mirrors the declaration in libunwind.
llvm-svn: 311576
The C++ ABI requires that the exception object (which under AEABI is the
`_Unwind_Control_Block`) is double-word aligned. The attribute was
applied to the `_Unwind_Exception` type, but not the
`_Unwind_Control_Block`. This should fix the libunwind test for the
alignment of the exception type.

OpenCL 2.0 atomic builtin functions have a scope argument which is ideally
represented as synchronization scope argument in LLVM atomic instructions.
Clang supports translating Clang atomic builtin functions to LLVM atomic
instructions. However it currently does not support synchronization scope
of LLVM atomic instructions. Without this, users have to use LLVM assembly
code to implement OpenCL atomic builtin functions.
This patch adds OpenCL 2.0 atomic builtin functions as Clang builtin
functions, which supports generating LLVM atomic instructions with
synchronization scope operand.
Currently only constant memory scope argument is supported. Support of
non-constant memory scope argument will be added later.

Clang specifies a max type alignment of 16 bytes on darwin targets (annoyingly in the driver not via cc1), meaning that the builtin nontemporal stores don't correctly align the loads/stores to 32 or 64 bytes when required, resulting in lowering to temporal unaligned loads/stores.
This patch casts the vectors to explicitly aligned types prior to the load/store to ensure that the require alignment is respected.

llvm-svn: 309327
Ensure that we define the `_Unwind_Control_Block` structure used on ARM
EHABI targets. This is needed for building libc++abi with the unwind.h
from the resource dir. A minor fallout of this is that we needed to
create a typedef for _Unwind_Exception to work across ARM EHABI and
non-EHABI targets. The structure definitions here are based originally
on the documentation from ARM under the "Exception Handling ABI for the
ARM® Architecture" Section 7.2. They are then adjusted to more closely
reflect the definition in libunwind from LLVM. Those changes are
compatible in layout but permit easier use in libc++abi and help
maintain compatibility between libunwind and the compiler provided
definition.

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

For a << b (as original vec_sl does), if b >= sizeof(a) * 8, the

the generated multiple instructions back to a single shift.

Summary: Previously global 64-bit versions of _Interlocked functions broke buildbots on i386, so now I'm adding them as builtins for x86-64 and ARM only (should they be also on AArch64? I had problems with testing it for AArch64, so I left it)

Summary: _BitScan intrinsics (and some others, for example _Interlocked and _bittest) are supposed to work on both ARM and x86. This is an attempt to isolate them, avoiding repeating their code or writing separate function for each builtin.

These were reverted in r283753 and r283747.
The first patch added a header to the root 'Headers' install directory,
instead of into 'Headers/cuda_wrappers'. This was fixed in the second
patch, but by then the damage was done: The bad header stayed in the
'Headers' directory, continuing to break the build.
We reverted both patches in an attempt to fix things, but that still
didn't get rid of the header, so the Windows boostrap build remained
broken.
It's probably worth fixing up our cmake logic to remove things from the
install dirs, but in the meantime, re-land these patches, since we
believe they no longer have this bug.

Summary:
We do this by wrapping <complex> and <algorithm>.
Tests are in the test-suite.

llvm-svn: 283679
Summary:
Currently we declare our inline __device__ math functions in namespace
std. But libstdc++ and libc++ declare these functions in an inline
namespace inside namespace std. We need to match this because, in a
later patch, we want to get e.g. <complex> to use our device overloads,
and it only will if those overloads are in the right inline namespace.

Summary: We need x86-64-specific builtins if we want to implement some of the MS intrinsics - winnt.h contains definitions of some functions for i386, but not for x86-64 (for example _InterlockedOr64), which means that we cannot treat them as builtins for both i386 and x86-64, because then we have definitions of builtin functions in winnt.h on i386.

This patch corresponds to review:
https://reviews.llvm.org/D24397
It adds the __POWER9_VECTOR__ macro and the -mpower9-vector option along with
a number of altivec.h functions (refer to the code review for a list).

On ARM, there are multiple versions of each of the intrinsics, with
acquire/relaxed/release barrier semantics.
The newly added ones are provided as inline functions here instead of builtins,
since they should only be available on certain archs (arm/aarch64).
This is necessary in order to compile C++ code for ARM in MSVC mode.

This patch adds the msa.h header file containing the shorter names for the
MSA instrinsics, e.g. msa_sll_b for builtin_msa_sll_b.

Summary:
We need to add a bunch more "using"s, which weren't necessary with
libstdc++.
Once this is in I can check in a test to the test-suite.
