however it will fail to output them if the type is not set correctly. This
can happen when it finds an attribute it hasn't seen before, for example
when building shared objects it will use the attributes from crti.o, hwever
this file has no attributes set.

Run configure for drill (I forgot to do it when I imported 1.6.17, but the
omission was harmless). Note that running configure --with-drill at the

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.

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AArch64-specific pseudo SDNode instructions that are superseded by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).

Currently the conversion check does not take place in a context where
