Unlike a lot of NEON instructions, vext isn't _actually_ parameterized by element size. Instead,
...
all of the different element sizes are pseudo instructions that map down to vext.8 underneath, with
the immediate shifted left to reflect the increased element size.

"The register specified for a dregpair is the corresponding Q register, so to
get the pair, we need to look up the sub-regs based on the qreg. Create a
lookup function since we don't have access to TargetRegisterInfo here to

Additionaly, fix the NEON VLD1* and VST1* instruction patterns not to use
the dregpair modifier for the 2xdreg versions. Explicitly specifying the two
registers as operands is more correct and more consistent with the other
instruction patterns. This enables further cleanup of special case code in the

Change ARM VFP VLDM/VSTM instructions to use addressing mode #4 , just like
...
all the other LDM/STM instructions. This fixes asm printer crashes when
compiling with -O0. I've changed one of the NEON tests (vst3.ll) to run
with -O0 to check this in the future.
Prior to this change VLDM/VSTM used addressing mode #5 , but not really.
The offset field was used to hold a count of the number of registers being
loaded or stored, and the AM5 opcode field was expanded to specify the IA
or DB mode, instead of the standard ADD/SUB specifier. Much of the backend
was not aware of these special cases. The crashes occured when rewriting
a frameindex caused the AM5 offset field to be changed so that it did not
have a valid submode. I don't know exactly what changed to expose this now.
Maybe we've never done much with -O0 and NEON. Regardless, there's no longer
any reason to keep a count of the VLDM/VSTM registers, so we can use
addressing mode #4 and clean things up in a lot of places.

They get expanded to the real VST4 instructions with 4 separate D register
operands. Once this conversion is complete, we'll be able to remove the

Add instruction encoding for the Neon VMOV immediate instruction. This changes
...
the machine instruction representation of the immediate value to be encoded
into an integer with similar fields as the actual VMOV instruction. This makes
things easier for the disassembler, since it can just stuff the bits into the
immediate operand, but harder for the asm printer since it has to decode the
value to be printed. Testcase for the encoding will follow later when MC has
more support for ARM.

Further changes for Neon vector shuffles:
...
- change isShuffleMaskLegal to show that all shuffles with 32-bit and 64-bit
elements are legal
- the Neon shuffle instructions do not support 64-bit elements, but we were
not checking for that before lowering shuffles to use them
- remove some 64-bit element vduplane patterns that are no longer needed

example, this:
(set DPR:$dst, (fsub (fneg (fmul DPR:$a, DPR:$b)), DPR:$dstin))
is ambiguous because DPR contains both f64 and v2f32. tblgen
currently accidentally picks f64 because it's first in the
regclass.

so I generalized the class for VTRN in the .td file to handle all 3 of them.

Implement Neon VTRN instructions. For now, anyway, these are selected

directly from the intrinsics produced by the frontend. If it is more
convenient to have a custom DAG node for using these to implement shuffles,
we can add that later.

When using NEON for single-precision FP, the NEON result must be placed in D0-D15 as these are the only D registers with S subregs. Introduce a new regclass to represent D0-D15 and use it in the NEON single-precision FP patterns.

Change DAG nodes for Neon VLD2/3/4 operations to return multiple results.

Get rid of yesterday's code to fix the register usage during isel.
Select the new DAG nodes to machine instructions. The new pre-alloc pass
to choose adjacent registers for these results is not done, so the
results of this will generally not assemble yet.

For other VLDn and VSTn operations, we need to list the multiple registers
explicitly anyway, so there's no point in special-casing this one usage.

- Add some NEON ld / st instruction static encoding.

- Make bits 25-27 for ldrh, etc. explicitly zero. Previously only the JIT uses the encoding information and it's assuming anything not specified to be zero. Making them explicit so the disassembler is happy.
