Adding support for Vector128.ExtractMostSignificantBits intrinsic on ARM64 LLVM.

Implementation

The implementation for LLVM follows the same approach as with miniJIT introduced in #84345.

To unify LLVM and miniJIT approaches, the previously introduced opcodes OP_ARM64_USHL and OP_ARM64_EXT_IMM were removed and replaced with INTRINS_AARCH64_ADV_SIMD_USHL and OP_XLOWER/OP_XUPPER as these were already supported on LLVM.

This change introduces a slight change in generated assembly by miniJIT. Specifically, in byte/sbyte element types scenario the code changes from:

and.16b v0, v0, v1 ldr q1,0x60 ushl.16b v0, v0, v1 eor.16b v1, v1, v1**ext.16b v2, v1, v0, #0x8** addv.16b b2, v2 umov.b w1, v2[0] ext.16b v0, v0, v1, #0x8 addv.16b b0, v0 umov.b w0, v0[0]lsl x0, x0, #8 orr w0, w0, w1

to:

and.16b v0, v0, v1 ldr q1,0x60 ushl.16b v0, v0, v1 eor.16b v1, v1, v1**mov.8b v1, v0** addv.16b b1, v1 umov.b w1, v1[0]**eor.16b v16, v16, v16** ext.16b v0, v0, v16, #0x8 addv.16b b0, v0 umov.b w0, v0[0]lsl x0, x0, #8 orr w0, w0, w1

The change removed 1xext.16b instruction and added two new ones (mov.8b and eor.16b). If this change introduces any significant regressions we can revert the change for miniJIT.

An extract of generated code for byte element type using LLVM fullAOT:

and.16b v0, v1, v0 ushl.16b v0, v0, v2 ext.16b v1, v0, v0, #0x8 addv.8b b0, v0 addv.8b b1, v1 fmov w9, s0 fmov w8, s1 orr w0, w9, w8,lsl #8

Contributes to #76025.

Adding support for Vector128.ExtractMostSignificantBits intrinsic on ARM64 LLVM.

Implementation

The implementation for LLVM follows the same approach as with miniJIT introduced in #84345.

To unify LLVM and miniJIT approaches, the previously introduced opcodes OP_ARM64_USHL and OP_ARM64_EXT_IMM were removed and replaced with INTRINS_AARCH64_ADV_SIMD_USHL and OP_XLOWER/OP_XUPPER as these were already supported on LLVM.

This change introduces a slight change in generated assembly by miniJIT. Specifically, in byte/sbyte element types scenario the code changes from:

and.16b v0, v0, v1 ldr q1,0x60 ushl.16b v0, v0, v1 eor.16b v1, v1, v1**ext.16b v2, v1, v0, #0x8** addv.16b b2, v2 umov.b w1, v2[0] ext.16b v0, v0, v1, #0x8 addv.16b b0, v0 umov.b w0, v0[0]lsl x0, x0, #8 orr w0, w0, w1

to:

and.16b v0, v0, v1 ldr q1,0x60 ushl.16b v0, v0, v1 eor.16b v1, v1, v1**mov.8b v1, v0** addv.16b b1, v1 umov.b w1, v1[0]**eor.16b v16, v16, v16** ext.16b v0, v0, v16, #0x8 addv.16b b0, v0 umov.b w0, v0[0]lsl x0, x0, #8 orr w0, w0, w1

The change removed 1xext.16b instruction and added two new ones (mov.8b and eor.16b). If this change introduces any significant regressions we can revert the change for miniJIT.

An extract of generated code for byte element type using LLVM fullAOT:

and.16b v0, v1, v0 ushl.16b v0, v0, v2 ext.16b v1, v0, v0, #0x8 addv.8b b0, v0 addv.8b b1, v1 fmov w9, s0 fmov w8, s1 orr w0, w9, w8,lsl #8

Contributes to #76025.
