assume that ::operator new provides no more alignment than is necessary for any
primitive type, except when we're on a GNU OS, where glibc's malloc guarantees
to provide 64-bit alignment on 32-bit systems and 128-bit alignment on 64-bit
systems. This can be controlled by the command-line -fnew-alignment flag.

Like NetBSD, OpenBSD prefers having a consistent set of typedefs
across the architectures it supports over strictly following the ARM
ABIs. The diff below makes sure that clang's view of those types
matches OpenBSD's system header files. It also adds a test that
checks the relevant types on all OpenBSD platforms that clang works
on. Hopefully we can add mips64 and powerpc to that list in the
future.

Summary:
This fixes a bug where we were unable to compile the following CUDA
file with libstdc++ (didn't try libc++):
#include <future>
void foo() { std::shared_future<int> x; }
The problem is that <future> only defines std::shared_future if
__GCC_ATOMIC_INT_LOCK_FREE > 1. When we compiled this file for device,
the macro was set to 1, and then the class didn't exist at all.

OpenCL requires __ENDIAN_LITTLE__ be set for little endian targets.
The default for targets was also apparently big endian, so AMDGPU
was incorrectly reported as big endian. Set this from the triple
so targets don't have another place to set the endianness.

I'm in the progress of adding ARMv6 support to CloudABI. On the compiler
side, everything seems to work properly with this tiny change applied.
llvm-svn: 280672
Summary:
We want wasm and asmjs to have matching ABIs, and right now asmjs uses
unsigned int for its size_t. This causes exported symbols in libcxx to
not match and can cause weird breakage where libcxx doesn't get linked
as a result. Long-term we probably want wasm32, wasm64, and asmjs to
all use unsigned long, but that would cause unnecessary ABI churn for
asmjs so defer that until we can make all the ABI changes at once.

Recently, Microsoft added support for a flag, /std, which controls which
version of the language rules MSVC should use.
MSVC hasn't updated __cplusplus though.
Instead, they added a new macro, _MSVC_LANG, which is defined in a
similar fashion to __cplusplus. This is used to indicate which mode the
compiler is in.

The PIC and PIE levels are not independent. In fact, if PIE is defined
it is always the same as PIC.
This is clear in the driver where ParsePICArgs returns a PIC level and
a IsPIE boolean. Unfortunately that is currently lost and we pass two
redundant levels down the pipeline.
This patch keeps a bool and a PIC level all the way down to codegen.

This reverts commit r270688 and r270689. The issue is not a random order, but a

Embedded ARM MachO targets are AAPCS but not full EABI (we don't use
__aeabi_whatever and the functions are allowed to be hard-float).
Turns out there was already a test for this, but its original purpose had
become corrupted over the years.

llvm-svn: 268951
This patch corresponds to reviews:
http://reviews.llvm.org/D15120http://reviews.llvm.org/D19125
It adds support for the __float128 keyword, literals and target feature to
enable it. Based on the latter of the two aforementioned reviews, this feature
is enabled on Linux on i386/X86 as well as SystemZ.
This is also the second attempt in commiting this feature. The first attempt
did not enable it on required platforms which caused failures when compiling
type_traits with -std=gnu++11.
If you see failures with compiling this header on your platform after this
commit, it is likely that your platform needs to have this feature enabled.

Replace use of /dev/null with /var/empty. lit will substitute the /dev/null
include path resulting in failures. Use a path under /var/empty which is
supposed to be empty to ensure that we can successfully test.
llvm-svn: 268784
From the GCC manpage:
-I dir
... If dir begins with =, then the = will be replaced by the sysroot prefix;
see --sysroot and -isysroot.
Add support to expand the `=` as a prefix of the include path with the sysroot
if specified. `-isysroot` takes precedence over `--sysroot` as the normal
argument behaviour occurs. The ordering of the `-isysroot` is relevant to the
path substituted. If no `--sysroot=` or `-isysroot` option is present, the = is
not expanded.
Resolves PR26965!

Summary:
Host and device types must match, otherwise when we pass values back and
forth between the host and device, we will get the wrong result.
This patch makes NVPTXTargetInfo inherit most of its type information

Summary:
According to the ACLE spec, "__ARM_FEATURE_FMA is defined to 1 if
the hardware floating-point architecture supports fused floating-point
multiply-accumulate".
This changes clang's behaviour from emitting this macro for v7-A and v7-R
cores to only emitting it when the target has VFPv4 (and therefore support
for the floating point multiply-accumulate instruction).

Since this patch provided support for the __float128 type but disabled it
on all platforms by default, some platforms can't compile type_traits with
-std=gnu++11 since there is a specialization with __float128.
This reverts the patch until D19125 is approved (i.e. we know which platforms
need this support enabled).
llvm-svn: 266460
This patch corresponds to review:
http://reviews.llvm.org/D15120
It adds support for the __float128 keyword, literals and a target feature to
enable it. This support is disabled by default on all targets and any target
that has support for this type is free to add it.
Based on feedback that I've received from target maintainers, this appears to
be the right thing for most targets. I have not heard from the maintainers of
X86 which I believe supports this type. I will subsequently investigate the
impact of enabling this on X86.

Summary:
The parsing logic has been separated out from the macro implementation logic, leading to a number of improvements:
* Gracefully handle unexpected/invalid tokens, too few, too many and nested parameters
* Provide consistent behaviour between all built-in feature-like macros
* Simplify the implementation of macro logic
* Fix __is_identifier to correctly return '0' for non-identifiers
