predicate and TB encoding fields. This fix the encoding for the
attached testcase. This fixes PR10625.

50b37c7920 Fix PR10656. It's only profitable to use 128-bit inserts and extracts 
when AVX mode is one. Otherwise is just more work for the type
legalizer.

f03bb260c9 Move "atomic" and "volatile" designations on instructions after the opcode 
of the instruction.

Note that this change affects the existing non-atomic load and store
instructions; the parser now accepts both forms, and the change is noted
in the release notes.

53cae1362d The VPERM2F128 is a AVX instruction which permutes between two 256-bit 
vectors. It operates on 128-bit elements instead of regular scalar
types. Recognize shuffles that are suitable for VPERM2F128 and teach
the x86 legalizer how to handle them.

b1831c6640 Allow loop unrolling to get known trip counts from ScalarEvolution. 
SCEV unrolling can unroll loops with arbitrary induction variables. It
is a prerequisite for -disable-iv-rewrite performance. It is also
easily handles loops of arbitrary structure including multiple exits
and is generally more robust.

This is under a temporary option to avoid affecting default
behavior for the next couple of weeks. It is needed so that I can
checkin unit tests for updateUnloop.

5e742a3e1b [AVX] If the data which is going to be saved is already in two XMM registers 
(for example, after integer operation), do not pack the registers into a YMM
before saving. Its better to save as two XMM registers.

Before:
                vinsertf128         $1, %xmm3, %ymm0, %ymm3
                vinsertf128         $0, %xmm1, %ymm3, %ymm1
                vmovaps              %ymm1, 416(%rsp)

After:
                vmovaps              %xmm3, 416+16(%rsp)
                vmovaps              %xmm1, 416(%rsp)

f4ea68fa5a fix PR10605 / rdar://9930964 by adding a pretty scary missed check. 
It's somewhat surprising anything works without this.  Before we would
compile the testcase into:

test:                                   # @test
	movl	$4, 8(%rdi)
	movl	8(%rdi), %eax
	orl	%esi, %eax
	cmpl	$32, %edx
	movl	%eax, -4(%rsp)          # 4-byte Spill
	je	.LBB0_2

now we produce:

test:                                   # @test
	movl	8(%rdi), %eax
	movl	$4, 8(%rdi)
	orl	%esi, %eax
	cmpl	$32, %edx
	movl	%eax, -4(%rsp)          # 4-byte Spill
	je	.LBB0_2

614061bfb4 When performing a truncating store, it is sometimes possible to rearrange the 
data in-register prior to saving to memory.  When we reorder the data in memory
we prevent the need to save multiple scalars to memory, making a single regular
store.

6ad251358e The following X86 pattern is incorrect: 
def : Pat<(X86Movss VR128:$src1,
                   (bc_v4i32 (v2i64 (load addr:$src2)))),
          (MOVLPSrm VR128:$src1, addr:$src2)>;
This matches a MOVSS dag with a MOVLPS instruction. However, MOVSS will replace only the low 32 bits of the register, while the MOVLPS instruction will replace the low 64 bits. A testcase is added and illustrates the bug and also modified the one that was already present. Patch by Tanya Lattner.

b1eede1281 Fix the LoopUnroller to handle nontrivial loops and partial unrolling. 
These are not individual bug fixes. I had to rewrite a good chunk of
the unroller to make it sane. I think it was getting lucky on trivial
completely unrolled loops with no early exits. I included some fairly
simple unit tests for partial unrolling. I didn't do much stress
testing, so it may not be perfect, but should be usable now.

4a74b3b933 Inflate register classes after coalescing. 
Coalescing can remove copy-like instructions with sub-register operands
that constrained the register class.  Examples are:

  x86: GR32_ABCD:sub_8bit_hi -> GR32
  arm: DPR_VFP2:ssub0 -> DPR

Recompute the register class of any virtual registers that are used by
less instructions after coalescing.

This affects code generation for the Cortex-A8 where we use NEON
instructions for f32 operations, c.f. fp_convert.ll:

  vadd.f32  d16, d1, d0
  vcvt.s32.f32  d0, d16

The register allocator is now free to use d16 for the temporary, and
that comes first in the allocation order because it doesn't interfere
with any s-registers.

66b0f515d5 Don't clobber pending ST regs when FP regs are killed. 
X86FloatingPoint keeps track of pending ST registers for an upcoming
inline asm instruction with fixed stack register constraints.  It does
this by remembering which FP register holds the value that should appear
at a fixed stack position for the inline asm.

When that FP register is killed before the inline asm, make sure to
duplicate it to a scratch register, so the ST register still has a live
FP reference.

This could happen when the same FP register was copied to two ST
registers, or when a spill instruction is inserted between the ST copy
and the inline asm.

This fixes PR10602.

06988bcf6a Made SCEV's UDiv expressions more canonical. When dividing a 
recurrence, the initial values low bits can sometimes be ignored.

To take advantage of this, added FoldIVUser to IndVarSimplify to fold
an IV operand into a udiv/lshr if the operator doesn't affect the
result.

-indvars -disable-iv-rewrite now transforms

i = phi i4
i1 = i0 + 1
idx = i1 >> (2 or more)
i4 = i + 4

into

i = phi i4
idx = i0 >> ...

7ce057983e ARM refactoring assembly parsing of memory address operands. 
Memory operand parsing is a bit haphazzard at the moment, in no small part
due to the even more haphazzard representations of memory operands in the .td
files. Start cleaning that all up, at least a bit.

The addressing modes in the .td files will be being simplified to not be
so monolithic, especially with regards to immediate vs. register offsets
and post-indexed addressing. addrmode3 is on its way with this patch, for
example.

This patch is foundational to enable going back to smaller incremental patches
for the individual memory referencing instructions themselves. It does just
enough to get the basics in place and handle the "make check" regression tests
we already have.

Follow-up work will be fleshing out the details and adding more robust test
cases for the individual instructions, starting with ARM mode and moving from
there into Thumb and Thumb2.

This includes registers like EFLAGS and ST0-ST7. We don't check for
liveness issues in the verifier and scavenger because registers will
never be allocated from these classes.

While in SSA form, we do care about the liveness of unallocatable
unreserved registers. Liveness of EFLAGS and ST0 neds to be correct for
MachineDCE and MachineSinking.

c37d4bbf1f Fix llvm-mc handing of x86 instructions that take 8-bit unsigned immediates. 
llvm-mc gives an "invalid operand" error for instructions that take an unsigned
immediate which have the high bit set such as:
    pblendw $0xc5, %xmm2, %xmm1
llvm-mc treats all x86 immediates as signed values and range checks them.
A small number of x86 instructions use the imm8 field as a set of bits.
This change only changes those instructions and where the high bit is not
ignored.  The others remain unchanged.

162ee5c725 Add a neat little two's complement hack for x86. 
On x86 we can't encode an immediate LHS of a sub directly. If the RHS comes from a XOR with a constant we can
fold the negation into the xor and add one to the immediate of the sub. Then we can turn the sub into an add,
which can be commuted and encoded efficiently.

This code is generated for __builtin_clz and friends.

6a32adc4e5 - Handle special scalar_to_vector case: splats. Using a native 128-bit 
shuffle before inserting on a 256-bit vector.
- Add AVX versions of movd/movq instructions
- Introduce a few COPY patterns to match insert_subvector instructions.
This turns a trivial insert_subvector instruction into a register copy,
coalescing the xmm into a ymm and avoid emiting on more instruction.

580f4a9c1c ARM assembly parsing and encoding for SSAT instruction. 
Fix the Rn register encoding for both SSAT and USAT. Update the parsing of the
shift operand to correctly handle the allowed shift types and immediate ranges
and issue meaningful diagnostics when an illegal value or shift type is
specified. Add aliases to parse an ommitted shift operand (default value of
'lsl #0').

Add tests for diagnostics and proper encoding.

f2a35fbd60 Move some ELF directives into ELF asm parser. 
The .local, .hidden, .internal, and .protected are not legal for all supported
file formats (in particular, they're invalid for MachO). Move the parsing for
them into the ELF assembly parser since that's the format they're for.
Similarly, .weak is used by COFF and ELF, but not MachO, so move the parsing
to the COFF and ELF asm parsers. Previously, using any of these directives
on Darwin would result in an assertion failure in the parser; now we get
a diagnostic as we should.

b09701db9e Correctly handle <undef> tied uses when rewriting after a split. 
This fixes PR10463. A two-address instruction with an <undef> use
operand was incorrectly rewritten so the def and use no longer used the
same register, violating the tie constraint.

Fix this by always rewriting <undef> operands with the register a def
operand would use.
