AVX512: shuff62x2 DAG lowering

[igorb]

Summary

AVX512: Implemented DAG lowering for shuff62x2/shufi62x2 instructions ( shuffle packed values at 128-bit granularity )
example

  shufflevector <8 x double> %x, <8 x double> %x1, <8 x i32> <i32 0, i32 1, i32 4, i32 5, i32 0, i32 1,  i32 4, i32 5>
Before optimization the follow instructions was generated:
  vmovdqa64	LCPI0_0(%rip), %zmm1
  vpermpd	%zmm0, %zmm1, %zmm0

After optimization:

vshuff64x2 $136, %zmm0, %zmm0, %zmm0

Shouldn't this be called DecodeVSHUF64x2Mask?

Is this actually necessary? I'd expect it to have been dealt with by canonicalization in lowerVectorShuffle.

Why isn't this CHECK-NEXT any more?

Nothing to do with this patch but its a shame that this is ANDing with a 512-bit constant mask instead of pre-ANDing with a 128-bit constant mask and then calling vpmovzxwq.

Simon, Thank you very much for your review! I have updated the patch according to your comments.

This function decode mask for SHUFF32x4/SHUFF64x2/SHUFI32x4/SHUFI64x2 instructions.

I can't do canonicalization for 256bit vector, lowerV2X128VectorShuffle can't be moved to lowerVectorShuffle, a lot of test failed.

This is AND with a 512-bit vector broadcasted from a 64-bit memory location.

vpandq	LCPI0_0(%rip){1to8}, %zmm1, %zmm1

You can use a macro to hide the bunch of "cases" and handle 256-bit form of these instructions.
You also can distinguish between memory and register forms in one boolean variable.

What I meant was the Decode functions in this file tend to be named after the x86 instruction itself and not the shuffle / ISD type. AFAICT all of these use the VSHUFF64x2 / VSHUFI64x2 instruction - that's why I suggested calling it DecodeVSHUF64x2Mask.

lib/Target/X86/X86ISelLowering.cpp

OK.
