Profiling tests *do* need a JIT. They'll pass if a cross-compiler targetting
AArch64 by default has been built, but fail if a native AArch64 compiler has
been build. Therefore XFAIL is inappropriate and we mark them unsupported.
ExecutionEngine tests are JIT by definition, they should also be unsupported.
Transforms/LICM only uses the interpreter to check the output is still sane
after optimisation. It can be switched to use an interpreter.

Previously we seemed to be assuming that all functions were definitions and all
methods were declarations. This may be consistent with how Clang uses DIBuilder
but doesn't have to be true of all clients (such as DragonEgg).

at this time, llvm is generating a different but equivalent pattern
that would lead to this instruction. I am trying to think of a way
to get it to generate this. If I can't, I may just remove the pseudo.

This expansion will be moved to expandISelPseudos as soon as I can figure
out how to do that. There are other instructions which use this
ExpandFEXT_T8I816_ins and as soon as I have finished expanding them all,
I will delete the macro asm string text so it has no way to be used
in the future.

This fixes PR15289. This bug was introduced (recently) in r175215; collecting
all std::vector references for candidate pairs to delete at once is invalid
because subsequent lookups in the owning DenseMap could invalidate the
references.
bugpoint was able to reduce a useful test case. Unfortunately, because whether
or not this asserts depends on memory layout, this test case will sometimes
appear to produce valid output. Nevertheless, running under valgrind will
reveal the error.

GCC warns about the attribute being ignored if it occurs after void*.
There seems to be some kind of incompatibility between clang and gcc here, but
I can't fathom who's right.
void* LLVM_LIBRARY_VISIBILITY foo(); // clang: hidden, gcc: default
LLVM_LIBRARY_VISIBILITY void *bar(); // clang: hidden, gcc: hidden
void LLVM_LIBRARY_VISIBILITY qux(); // clang: hidden, gcc: hidden

arguably better than forward iterators for this use case, they are confusing and
there are some implementation problems with reverse iterators and MI bundles.

MachineBasicBlock::SplitCriticalEdge. Since this is an iterator rather than
an instr_iterator, the isBundled() check only passes if getFirstTerminator()
returned end() and the garbage memory happens to lean that way.
Multiple successors can be present without any terminator instructions in the
case of exception handling with a fallthrough.

terminators that actually have register uses when splitting critical edges.
This commit also introduces a method repairIntervalsInRange() on LiveIntervals,
which allows for repairing LiveIntervals in a small range after an arbitrary
target hook modifies, inserts, and removes instructions. It's pretty limited
right now, but I hope to extend it to support all of the things that are done
by the convertToThreeAddress() target hooks.

(or (bool?A:B),(bool?C:D)) --> (bool?(or A,C):(or B,D))
By the time the OR is visited, both the SELECTs have been visited and not
optimized and the OR itself hasn't been transformed so we do this transform in
the hopes that the new ORs will be optimized.
The transform is explicitly disabled for vector-selects until "codegen matures
to handle them better".

Avoids malloc and is a lot denser. We lose iteration over target independent
attributes, but that's a strange interface anyways and didn't have any users
outside of AttrBuilder.

when I do it. I've been experimenting with this. No new test cases
are needed.

GNU as rejects them and there are configure scripts in the wild that check if
the assembler rejects ".align 3" to determine whether the alignment is in bytes
or powers of two.

It's completely unnecessary and can be replace with proper
SReg_64 handling instead.
This actually fixes a piglit test on SI.
v2: use correct register class in addRegisterClass,
set special classes as not allocatable
v3: revert setting special classes as not allocateable
This is a candidate for the stable branch.

Seems to be allot simpler, and also paves the
way for further improvements.
v2: rebased on master, use 0 in BUFFER_LOAD_FORMAT_XYZW,
use VGPR0 in dummy EXP, avoid compiler warning, break
after encoding the first literal.
v3: correctly use V_ADD_F32_e64
