Various targets use std::swap on specific MCAsmOperands (ARM and

as final, to ensure that the availability of move/copy operations can't
lead to slicing. (same sort of requirements as the non-vitual dtor -

AMDGPU/SI: Add implicit register operands in the correct order.
This commit fixes a bug in the class 'SIInstrInfo' where the implicit register
machine operands were added to a machine instruction in an incorrect order -
the implicit uses were added before the implicit defs.
I found this bug while working on moving the implicit register operand
verification code from the MIR parser to the machine verifier.
This commit also makes the method 'addImplicitDefUseOperands' in the machine
instruction class public so that it can be reused in the 'SIInstrInfo' class.

IR: Add a broad bitcode compatibility test
Successive versions of LLVM should retain the ability to parse bitcode
generated by old releases of the compiler. This adds a bitcode format
compatibility test, which is intended to provide good (albeit not
entirely exhaustive) coverage of the current LangRef.
This also includes compatibility tests for LLVM 3.6. After every 3.X.0
release, the compatibility.ll file from the 3.X branch should be copied
to compatibility-3.X.ll on trunk, and the 3.X.0 release used to generate
a corresponding bitcode file.

- The printer isn't factored out to handle recursive AST code yet, since it can't even handle control flow anyways.
- The assembly format isn't full s-expressions yet either, this will be added later.
- This currently disables PrologEpilogCodeInserter as well as MachineCopyPropagation becasue they don't like virtual registers, which WebAssembly likes quite a bit. This will be fixed by factoring out NVPTX's change (currently a fork of PrologEpilogCodeInserter).

fix memcpy/memset/memmove lowering when optimizing for size
Fixing MinSize attribute handling was discussed in D11363.
This is a prerequisite patch to doing that.
The handling of OptSize when lowering mem* functions was broken
on Darwin because it wants to ignore -Os for these cases, but the
existing logic also made it ignore -Oz (MinSize).
The Linux change demonstrates a widespread problem. The backend
doesn't usually recognize the MinSize attribute by itself; it
assumes that if the MinSize attribute exists, then the OptSize
attribute must also exist.
Fixing this more generally will be a follow-on patch or two.

[mips][FastISel] Apply only zero-extension to constants prior to their materialization.
Summary:
Previously, we would sign-extend non-boolean negative constants and
zero-extend otherwise. This was problematic for PHI instructions with
negative values that had a type with bitwidth less than that of the
register used for materialization.
More specifically, ComputePHILiveOutRegInfo() assumes the constants
present in a PHI node are zero extended in their container and
afterwards deduces the known bits.
For example, previously we would materialize an i16 -4 with the
following instruction:
addiu $r, $zero, -4
The register would end-up with the 32-bit 2's complement representation
of -4. However, ComputePHILiveOutRegInfo() would generate a constant
with the upper 16-bits set to zero. The SelectionDAG builder would use
that information to generate an AssertZero node that would remove any
subsequent trunc & zero_extend nodes.
In theory, we should modify ComputePHILiveOutRegInfo() to consult
target-specific hooks about the way they prefer to materialize the
given constants. However, git-blame reports that this specific code
has not been touched since 2011 and it seems to be working well for every
target so far.

The fix here was to use std::enable_if for overload resolution. Thanks to David
Blaikie for lots of help on this, and for the extra tests!
Original commit message follows:
For cases where we needed a foreach loop in reverse over a container,
we had to do something like
for (const GlobalValue *GV : make_range(TypeInfos.rbegin(),
TypeInfos.rend())) {
This provides a convenience method which shortens this to
for (const GlobalValue *GV : reverse(TypeInfos)) {
There are 2 versions of this, with a preference to the rbegin() version.
The first uses rbegin() and rend() to construct an iterator_range.
The second constructs an iterator_range from the begin() and end() methods
wrapped in std::reverse_iterator's.

schedulers looks like it has no effect on Cortex-A53 or A57. In general you'd
expect a MOV to be about the most efficient instruction with its semantics,
even though the official "UXTW" alias is really a UBFX.

[X86][SSE] Vectorize i64 ASHR operations
This patch vectorizes the v2i64/v4i64 ASHR shift operations - the last remaining integer vector shifts that are still being transferred to/from the scalar unit to be completed.

Revert "Add reverse(ContainerTy) range adapter."
This reverts commit r243563.
The GCC buildbots were extremely unhappy about this. Reverting while
we discuss a better way of doing overload resolution.

Add reverse(ContainerTy) range adapter.
For cases where we needed a foreach loop in reverse over a container,
we had to do something like
for (const GlobalValue *GV : make_range(TypeInfos.rbegin(),
TypeInfos.rend())) {
This provides a convenience method which shortens this to
for (const GlobalValue *GV : reverse(TypeInfos)) {
There are 2 versions of this, with a preference to the rbegin() version.
The first uses rbegin() and rend() to construct an iterator_range.
The second constructs an iterator_range from the begin() and end() methods
wrapped in std::reverse_iterator's.

[ASan] Disable dynamic alloca and UAR detection in presence of returns_twice calls.
Summary:
returns_twice (most importantly, setjmp) functions are
optimization-hostile: if local variable is promoted to register, and is
changed between setjmp() and longjmp() calls, this update will be
undone. This is the reason why "man setjmp" advises to mark all these
locals as "volatile".
This can not be enough for ASan, though: when it replaces static alloca
with dynamic one, optionally called if UAR mode is enabled, it adds a
whole lot of SSA values, and computations of local variable addresses,
that can involve virtual registers, and cause unexpected behavior, when
these registers are restored from buffer saved in setjmp.
To fix this, just disable dynamic alloca and UAR tricks whenever we see
a returns_twice call in the function.
