Summary:
See comments in patch; we were assuming that some stdlib math functions
would be defined in namespace std, when in fact the spec says they
should be defined in the global namespace. libstdc++4.9 became more
conforming and broke us.
This new implementation seems to cover the known knowns.

Summary:
This is necessary for a future patch which will make all constexpr
functions implicitly host+device. cmath may declare constexpr
functions, but these we do *not* want to be host+device. The forward
declares added in this patch prevent this (because the rule will be,
constexpr functions become implicitly host+device unless they're
preceeded by a decl with __device__).

Summary:
We decided this makes life too difficult for code authors. For example,
people may want to detect NVCC and disable variadic templates, which
NVCC does not support, but which we do.
Since people are going to have to change compiler flags *anyway* in
order to compile with clang, if they really want the old behavior, they
can pass -D__NVCC__.
Tested with tensorflow and thrust, no apparent problems.

Summary:
This lets you write, e.g.
uint3 a = threadIdx;
uint3 b = blockIdx;
dim3 c = gridDim;
dim3 d = blockDim;
which is legal in nvcc, but was not legal in clang.
The fact that e.g. the type of threadIdx is not actually uint3 is still
observable, but now you have to try to observe it.

Summary:
curand.h includes curand_mtgp32_kernel.h. In host mode, this header
redefines threadIdx and blockDim, giving them their "proper" types of
uint3 and dim3, respectively.
clang has its own plan for these variables -- their types are magic
builtin classes. So these redefinitions are incompatible.
As a hack, we force-include the offending CUDA header and use #defines
to get the right types for threadIdx and blockDim.

CUDA expects math functions in std:: namespace to work on device side.
In order to make it work with clang without allowing device-side code
generation for functions w/o appropriate target attributes, this patch
provides device-side implementations for <cmath> functions. Most of
them call global-scope math functions provided by CUDA headers. In few

Currently it's easy to break CUDA compilation by passing
"-isystem /path/to/cuda/include" to compiler which leads to
compiler including real cuda_runtime.h from there instead

Header files that come with CUDA are assuming split host/device
compilation and are not usable by clang out of the box.
With a bit of preprocessor magic it's possible to twist them
into something clang can use.
This wrapper always includes CUDA headers exactly the same way during
host and device compilation passes and produces identical preprocessed
content during host and device side compilation for sm_35 GPUs. Device
compilation passes for older GPUs will see a smaller subset of device
functions supported by particular GPU.
The wrapper assumes specific contents of CUDA header files and works
only with CUDA 7.0 and 7.5.

These two intrinsics are defined in arm_acle.h.
__rev16l needs to rotate by 16 bits, bit it was actually rotating by 2 bits.
For AArch64, where long is 64 bits, this would still be wrong.
__rev16ll was incorrect, it reversed the bytes in each 32-bit word, rather than
each 16-bit halfword. The correct implementation is to apply __rev16 to the top
and bottom words of the 64-bit value.
For AArch32 targets, these get compiled down to the hardware rev16 instruction
at -O1 and above. For AArch64 targets, the 64-bit ones get compiled to two
32-bit rev16 instructions, because there is not currently a pattern for the
64-bit rev16 instruction.

test that our intrinsics behave the same under -fsigned-char and
-funsigned-char.
This further testing uncovered that AVX-2 has a broken cmpgt for 8-bit
elements, and has for a long time. This is fixed in the same way as
SSE4 handles the case.
The other ISA extensions currently work correctly because they use
specific instruction intrinsics. As soon as they are rewritten in terms
of generic IR, they will need to add these special casts. I've added the
necessary testing to catch this however, so we shouldn't have to chase
it down again.
I considered changing the core typedef to be signed, but that seems like
a bad idea. Notably, it would be an ABI break if anyone is reaching into
the innards of the intrinsic headers and passing __v16qi on an API
boundary. I can't be completely confident that this wouldn't happen due
to a macro expanding in a lambda, etc., so it seems much better to leave
it alone. It also matches GCC's behavior exactly.
A fun side note is that for both GCC and Clang, -funsigned-char really
does change the semantics of __v16qi. To observe this, consider:
% cat x.cc
#include <smmintrin.h>
#include <iostream>
int main() {
__v16qi a = { 1, -1, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0};
__v16qi b = _mm_set1_epi8(-1);
std::cout << (int)(a / b)[0] << ", " << (int)(a / b)[1] << '\n';
}
% clang++ -o x x.cc && ./x
-1, 1
% clang++ -funsigned-char -o x x.cc && ./x
0, 1
However, while this may be surprising, both Clang and GCC agree.
Differential Revision: http://reviews.llvm.org/D13324
llvm-svn: 249097
recently when we started using direct conversion to model sign
extension. The __v16qi type we use for SSE v16i8 vectors is defined in
terms of 'char' which may or may not be signed! This causes us to
generate pmovsx and pmovzx depending on the setting of -funsigned-char.
This patch just forms an explicitly signed type and uses that to
formulate the sign extension. While this gets the correct behavior
(which we now verify with the enhanced test) this is just the tip of the
ice berg. Now that I know what to look for, I have found errors of this
sort *throughout* our vector code. Fortunately, this is the only
specific place where I know of users actively having their code
miscompiled by Clang due to this, so I'm keeping the fix for those users
minimal and targeted.
I'll be sending a proper email for discussion of how to fix these
systematically, what the implications are, and just how widely broken
this is... From what I can tell, we have never shipped a correct set of
builtin headers for x86 when users rely on -funsigned-char. Oops.

Before, clang's internal assembler would reject the inline asm in clang's

This patch adds support for the System Z vector built-in functions.
The API-defined header file has the name vecintrin.h.
The user-level functions are defined in the same style as the clang
version of altivec.h, making heavy use of the __overloadable__ and
__always_inline__ attributes. Where possible the functions expand to
generic operations rather than specific built-in functions, in the hope
that that form can be optimised better.
Where a built-in routine is specified to require an immediate integer
argument, the __enable_if__ attribute is used to verify the argument is
in fact constant and in the appropriate range.
Based on a patch by Richard Sandiford.

The 3DNOW/PRFCHW cpu targets define both the PREFETCHW (set cache line modified) and PREFETCH (set cache line exclusive) instructions but only the _m_prefetchw (PREFETCHW) intrinsic is included in the header. This patch adds the missing _m_prefetch intrinsic.
I'm basing this off AMD documentation - the intel docs on the support for PREFETCHW isn't clear whether Silvermont/Broadwell properly support PREFETCH but given that the intrinsic implementation is a default __builtin_prefetch call, it is safe whatever.

_ReadBarrier, _WriteBarrier, and _ReadWriteBarrier are essentially

__faststorefence is a curious intrinsic. It's single purpose seems to

is not always slow and is, in general, preferable to a 'lock or'
sequence on certain CPUs. Give the compiler freedom to select the best

The vec_sld interface provides access to the vsldoi instruction.
Unlike most of the vec_* interfaces, we do not attempt to change the
generated code for vec_sld based on the endian mode. It is too
difficult to correctly infer the desired semantics because of
different element types, and the corrected instruction sequence is
expensive, involving loading a permute control vector and performing a
generalized permute.
For GCC, this was implemented as "Don't touch the vec_sld"
implementation. When it came time for the LLVM implementation, I did
the same thing. However, this was hasty and incorrect. In LLVM's
version of altivec.h, vec_sld was previously defined in terms of the
vec_perm interface. Because vec_perm semantics are adjusted for
little endian, this means that leaving vec_sld untouched causes it to
generate something different for LE than for BE. Not good.
This patch adjusts the form of vec_perm that is used for vec_sld and
vec_vsldoi, effectively undoing the modifications so that the same
vsldoi instruction will be generated for both BE and LE.
There is an accompanying back-end patch to take care of some small
ripple effects caused by these changes.

add 2 bit to ObjCOrBuiltinID (changed from 11bits to 13bits), see discussion in
Add new intrinsics support that already covered by the BE.
All the intrinsics are covered by tests
Differential Revision: http://reviews.llvm.org/D10893
llvm-svn: 242144
Three things:
- The atomic intrinsics mandate memory barriers, let's start emitting
some.
- We don't need to manually create RMW operations, we can just do
__atomic_fetch_foo instead of performing __atomic_foo_fetch and
undoing foo.
- Don't use inline assembly, we don't need it for these intrinsics.
This fixes PR24101.
llvm-svn: 242009
This patch corresponds to review:
http://reviews.llvm.org/D10972
Fix for the handling of dependent features that are enabled by default
on some CPU's (such as -mvsx, -mpower8-vector).
Also provides a number of new interfaces or fixes existing ones in
altivec.h.
Changed signatures to conform to ABI:
