Duncan P. N. Exon Smith 78b66ecd70 Revert "Bitcode: ArrayRef-ize EmitRecordWithAbbrev(), NFC"
This reverts commit r247107.  Turns out clang calls these functions
directly, and `ArrayRef<T>` doesn't have a working implicit conversion
from `SmallVector<T>`.

Duncan P. N. Exon Smith 98b3cd9280 Bitcode: ArrayRef-ize EmitRecordWithAbbrev(), NFC
Change `EmitRecordWithAbbrev()` and friends to take an `ArrayRef<T>`
instead of requiring a `SmallVectorImpl<T>`.  No functionality change
intended.

Davide Italiano 9a429b766f [llvm-readobj] MachO -- dump LinkerOptions load command.
Example output:

Linker Options {
  Size: 32
  Count: 2
  Strings [
    Value: -framework
    Value: Cocoa
  ]
}

There were only two tests using this -- so I converted them as part of
this commit rather than separately.

Michael Zolotukhin 84df12375c Introduce __builtin_nontemporal_store and __builtin_nontemporal_load.
Summary:
Currently clang provides no general way to generate nontemporal loads/stores.
There are some architecture specific builtins for doing so (e.g. in x86), but
there is no way to generate non-temporal store on, e.g. AArch64. This patch adds
generic builtins which are expanded to a simple store with '!nontemporal'
attribute in IR.

Devin Coughlin 00691e3169 Revert "[Static Analyzer] BugReporter.cpp:2869: Assertion failed: !RemainingNodes.empty() && "No error node found in the trimmed graph""
This is making our internal build bot fail because it results in extra warnings being
emitted past what should be sink nodes. (There is actually an example of this in the
updated malloc.c test in the reverted commit.)

I'm working on a patch to fix the original issue by adding a new checker API to explicitly
create error nodes. This API will ensure that error nodes are always tagged in order to
prevent them from being reclaimed.

This reverts commit r246188.

Reid Kleckner 51189f0a1d [WinEH] Avoid creating MBBs for LLVM BBs that cannot contain code
Typically these are catchpads, which hold data used to decide whether to
catch the exception or continue unwinding. We also shouldn't create MBBs
for catchendpads, cleanupendpads, or terminatepads, since no real code
can live in them.

This fixes a problem where MI passes (like the register allocator) would
try to put code into catchpad blocks, which are not executed by the
runtime. In the new world, blocks ending in invokes now have many
possible successors.

Using '-f FILTER' or unnamed arguments (directories) to dotest.py

Evgeniy Stepanov 4c2dd111f2 [msan] Unpoison dlpi_phdr in dl_iterate_phdr.
In some cases, PHDR table is allocated with malloc() by the linker
instead of being mapped from file. It needs to be unpoisoned in the
dl_iterate_phdr callback then.

This happens when program headers are not part of any loadable ELF
segment.

Alexey Samsonov 63eaeca7d0 [CMake] Remove all uses of LLVM_NATIVE_ARCH.
Instead, assume we're going to target triple specified by
COMPILER_RT_DEFAULT_TARGET_TRIPLE and build runtimes for this triple
(and hope that the host compiler can target them).

This will help users that use cross-compiler on their host to build
Clang that would work on a different architecture. This will also come in
handy if one would want to configure several compiler-rt build trees on
the same host, using just-built Clang that can target many
architectures.

This doesn't change the behavior in the default build configuration.

Reid Kleckner df1295173f [WinEH] Emit prologues and epilogues for funclets
Summary:
32-bit funclets have short prologues that allocate enough stack for the
largest call in the whole function. The runtime saves CSRs for the
funclet. It doesn't restore CSRs after we finally transfer control back
to the parent funciton via a CATCHRET, but that's a separate issue.
32-bit funclets also have to adjust the incoming EBP value, which is
what llvm.x86.seh.recoverframe does in the old model.

64-bit funclets need to spill CSRs as normal. For simplicity, this just
spills the same set of CSRs as the parent function, rather than trying
to compute different CSR sets for the parent function and each funclet.
64-bit funclets also allocate enough stack space for the largest
outgoing call frame, like 32-bit.

Peter Collingbourne c634ed0b1a LowerBitSets: Extend pass to support functions as bitset members.
This change extends the bitset lowering pass to support bitsets that may
contain either functions or global variables. A function bitset is lowered to
a jump table that is laid out before one of the functions in the bitset.

Also add support for non-string bitset identifier names. This allows for
distinct metadata nodes to stand in for names with internal linkage,
as done in D11857.

Johannes Doerfert 717b866798 Allow PHI nodes in the region exit block
While we do not need to model PHI nodes in the region exit (as it is not part
  of the SCoP), we need to prepare for the case that the exit block is split in
  code generation to create a single exiting block. If this will happen, hence
  if the region did not have a single exiting block before, we will model the
  operands of the PHI nodes as escaping scalars in the SCoP.
