Summary:
Historically, NetBSD, FreeBSD and OpenBSD have defined the macro ABICALLS in
the preprocessor when -mabicalls is in effect.
Mainline GCC later defined __mips_abicalls when -mabicalls is in effect.
This patch teaches the preprocessor to define these macros when appropriate.
NetBSD does not require the ABICALLS macro.
This resolves PR/31694.
Thanks to Sean Bruno for highlighting this issue!

GCC 7 will predefine two new macros on s390x:
- __ARCH__ indicates the ISA architecture level
- __VX__ indicates that the vector facility is available
This adds those macros to clang as well to ensure continued
compatibility with GCC.

GCC does not generate `__unix` nor `unix` macros. The latter already
intrudes into the user's namespace and should be avoided. Use the
canonical spelling of `__unix__` across all the targets.

Summary:
This patch enables the following
1. AMD family 17h architecture using "znver1" tune flag (-march, -mcpu).
2. ISAs that are enabled for "znver1" architecture.
3. Checks ADX isa from cpuid to identify "znver1" flag when -march=native is used.
4. ISAs FMA4, XOP are disabled as they are dropped from amdfam17.
5. For the time being, it uses the btver2 scheduler model.
6. Test file is updated to check this flag.

Summary:
CUDA lets users share structs between the host and device, so for that
and other reasons, primitive types such as ptrdiff_t should be the same
on both sides of the compilation.
Our code to do this wasn't entirely successful. In particular, we did a
bunch of work during the NVPTXTargetInfo constructor, only to override
it in the NVPTX{32,64}TargetInfo constructors. It worked well enough on
Linux and Mac, but Windows is LLP64, which is different enough to break
it.
This patch removes the NVPTX{32,64}TargetInfo classes entirely and fixes
the bug described above.

This patch adds barebones support in Clang for the (experimental) AVR target. It uses the integrated assembler for assembly, and the GNU linker for linking, as lld doesn't know about the target yet.
The DataLayout string is the same as the one in AVRTargetMachine.cpp. The alignment specs look wrong to me, as it's an 8 bit target and all types only need 8 bit alignment. Clang failed with a datalayout mismatch error when I tried to change it, so I left it that way for now.

Summary:
This used to work because system headers are found in a (somewhat)
predictable set of locations on Linux. But this is not the case on
MacOS; without this change, we don't look in the right places for our

For compatibility with other compilers on the platform, allow specifying
levels of the z/Architecture instead of model names with -march. In
particular, the following aliases are now supported:
-march=arch8 equals -march=z10
-march=arch9 equals -march=z196
-march=arch10 equals -march=zEC12
-march=arch11 equals -march=z13
This parallels the equivalent (and prerequisite) LLVM change in r285577.

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.
