to include the Unaligned Access and Floating-point Half-precision
attributes. the former marks ELF objects that may access ARMv6 style
unaligned data, the latter that the binary uses the VFPv3/Advanced SIMD
half-precision extension.
These may be emmitted by clang so it's best to print a warning when the
linker hits one of them.

Fix assert instantiating string init of static variable
... when the variable's type is a typedef of a ConstantArrayType. Just
look through the typedef (and any other sugar). We only use the
constant array type here to get the element count.
This fixes an assertion failure when building the games/redeclipse port.

where we want to create a new IP datagram.
o Add support for RFC6864, which allows to set IP ID for atomic IP
datagrams to any value, to improve performance. The behaviour is
controlled by net.inet.ip.rfc6864 sysctl knob, which is enabled by
default.
o In case if we generate IP ID, use counter(9) to improve performance.
o Gather all code related to IP ID into ip_id.c.

The __builtin_init_dwarf_reg_size_table function is unimplemented in
clang 3.6 for AArch64. Comment it out for now and replace it with
a message and abort.
Tracked in upstream LLVM PR 22997
https://llvm.org/bugs/show_bug.cgi?id=22997
Submitted by: andrew
As is described at http://llvm.org/bugs/show_bug.cgi?id=22408, the GNU
linkers ld.bfd and ld.gold currently only support a subset of the
whole range of AArch64 ELF TLS relocations. Furthermore, they assume
that some of the code sequences to access thread-local variables are
produced in a very specific sequence. When the sequence is not as the
linker expects, it can silently mis-relaxe/mis-optimize the
instructions.
Even if that wouldn't be the case, it's good to produce the exact
sequence, as that ensures that linkers can perform optimizing
relaxations.
This patch:
* implements support for 16MiB TLS area size instead of 4GiB TLS area
size. Ideally clang would grow an -mtls-size option to allow support
for both, but that's not part of this patch.
* by default doesn't produce local dynamic access patterns, as even
modern ld.bfd and ld.gold linkers do not support the associated
relocations. An option (-aarch64-elf-ldtls-generation) is added to
enable generation of local dynamic code sequence, but is off by
default.
* makes sure that the exact expected code sequence for local dynamic
and general dynamic accesses is produced, by making use of a new
pseudo instruction. The patch also removes two
(AArch64ISD::TLSDESC_BLR, AArch64ISD::TLSDESC_CALL) pre-existing
AArch64-specific pseudo SDNode instructions that are superseded by
the new one (TLSDESC_CALLSEQ).

[libcxx] Fix PR22771 - Support access control SFINAE in the library
version of is_convertible.
Summary:
Currently the conversion check does not take place in a context where
access control SFINAE is applied. This patch changes the context of
the test expression so that SFINAE occurs if access control does not
permit the conversion.

Changes affecting future time stamps
Mongolia will start observing DST again this year, from the last
Saturday in March at 02:00 to the last Saturday in September at 00:00.
(Thanks to Ganbold Tsagaankhuu.)
Palestine will start DST on March 28, not March 27. Also,
correct the fall 2014 transition from September 26 to October 24.
Adjust future predictions accordingly. (Thanks to Steffen Thorsen.)
Changes affecting past time stamps
The 1982 zone shift in Pacific/Easter has been corrected, fixing a 2015a
regression. (Thanks to Stuart Bishop for reporting the problem.)
Some more zones have been turned into links, when they differed
from existing zones only for older time stamps. As usual,
these changes affect UTC offsets in pre-1970 time stamps only.
Their old contents have been moved to the 'backzone' file.
The affected zones are: America/Antigua, America/Cayman,
Pacific/Midway, and Pacific/Saipan.
Changes affecting time zone abbreviations
Correct the 1992-2010 DST abbreviation in Volgograd from "MSK" to "MSD".
(Thanks to Hank W.)
ARM: treat [N x i32] and [N x i64] as AAPCS composite types
The logic is almost there already, with our special homogeneous
aggregate handling. Tweaking it like this allows front-ends to emit
AAPCS compliant code without ever having to count registers or add
discarded padding arguments.
Only arrays of i32 and i64 are needed to model AAPCS rules, but I
decided to apply the logic to all integer arrays for more consistency.
This fixes a possible "Unexpected member type for HA" error when
compiling lib/msun/bsdsrc/b_tgamma.c for armv6.

These are generated, and not "optimized" in any way, since I am not
entirely sure of the syntax or format of this type of file. Feel free
to suggest ways of shortening these lists.
The general idea is the same for all three files, though:
* Get rid of upstream build infrastructure (CMakeLists, Makefiles, etc)
* Delete tests, tools and utilities we don't want or use (including
samples)
* Remove various bits of upstream metadata files that we don't want or
use (.arcconfig, .gitignore, etc)

This change comes from 8.15 but is being backported to FreeBSD releases
not yet using 8.15.
