Revert of Turbofan: Add MachineOperators for SIMD. (patchset #5 id:70001 of https://codereview.chromium.org/1848433003/ ) Reason for revert: [Sheriff] Speculative revert. Compile now times out on msan: https://build.chromium.org/p/client.v8/builders/V8%20Linux%20-%20arm64%20-%20sim%20-%20MSAN/builds/7705 Original issue's description: > Turbofan: Add MachineOperators for SIMD. > > Takes the SIMD runtime intrinsics as a starting point for defining TF machine operators. The rationale for omitting functions is: > > - UInt constructors. int and uint aren't distinguished in wasm. > - Check functions. > - 'FromXxxBits' functions. These are essentially casts. > - Simple Load / Store functions. Existing load / store with SIMD type should work. > - Uint functions, except where their behavior is bitwise different from the Int function. > > Skipped fns: > > Float32x4Check > Float32x4FromInt32x4Bits > Float32x4FromUint32x4Bits > Float32x4FromInt16x8Bits > Float32x4FromUint16x8Bits > Float32x4FromInt8x16Bits > Float32x4FromUint8x16Bits > Float32x4Load > Float32x4Store > > Int32x4Check > Int32x4FromUint32x4 > Int32x4FromFloat32x4Bits > Int32x4FromUint32x4Bits > Int32x4FromInt16x8Bits > Int32x4FromUint16x8Bits > Int32x4FromInt8x16Bits > Int32x4FromUint8x16Bits > Int32x4Load > Int32x4Store > > CreateUint32x4 > Uint32x4Check > Uint32x4ExtractLane > Uint32x4ReplaceLane > Uint32x4Add > Uint32x4Sub > Uint32x4Mul > Uint32x4And > Uint32x4Or > Uint32x4Xor > Uint32x4Not > Uint32x4Equal > Uint32x4NotEqual > Uint32x4Select > Uint32x4Swizzle > Uint32x4Shuffle > Uint32x4FromInt32x4 > Uint32x4FromFloat32x4Bits > Uint32x4FromInt32x4Bits > Uint32x4FromInt16x8Bits > Uint32x4FromUint16x8Bits > Uint32x4FromInt8x16Bits > Uint32x4FromUint8x16Bits > Uint32x4Load > Uint32x4Load1 > Uint32x4Load2 > Uint32x4Load3 > Uint32x4Store > Uint32x4Store1 > Uint32x4Store2 > Uint32x4Store3 > > Bool32x4Check > > Int16x8Check > Int16x8FromUint16x8 > Int16x8FromFloat32x4Bits > Int16x8FromInt32x4Bits > Int16x8FromUint32x4Bits > Int16x8FromUint16x8Bits > Int16x8FromInt8x16Bits > Int16x8FromUint8x16Bits > Int16x8Load > Int16x8Store > > CreateUint16x8 > Uint16x8Check > Uint16x8ExtractLane > Uint16x8ReplaceLane > Uint16x8Add > Uint16x8Sub > Uint16x8Mul > Uint16x8And > Uint16x8Or > Uint16x8Xor > Uint16x8Not > Uint16x8Equal > Uint16x8NotEqual > Uint16x8Select > Uint16x8Swizzle > Uint16x8Shuffle > Uint16x8FromInt16x8 > Uint16x8FromFloat32x4Bits > Uint16x8FromInt32x4Bits > Uint16x8FromUint32x4Bits > Uint16x8FromInt16x8Bits > Uint16x8FromInt8x16Bits > Uint16x8FromUint8x16Bits > Uint16x8Load > Uint16x8Store > > Bool16x8Check > > Int8x16Check > Int8x16FromUint8x16 > Int8x16FromFloat32x4Bits > Int8x16FromInt32x4Bits > Int8x16FromUint32x4Bits > Int8x16FromInt16x8Bits > Int8x16FromUint16x8Bits > Int8x16FromUint8x16Bits > Int8x16Load > Int8x16Store > > CreateUint8x16 > Uint8x16Check > Uint8x16ExtractLane > Uint8x16ReplaceLane > Uint8x16Add > Uint8x16Sub > Uint8x16Mul > Uint8x16And > Uint8x16Or > Uint8x16Xor > Uint8x16Not > Uint8x16Equal > Uint8x16NotEqual > Uint8x16Select > Uint8x16Swizzle > Uint8x16Shuffle > Uint8x16FromInt8x16 > Uint8x16FromFloat32x4Bits > Uint8x16FromInt32x4Bits > Uint8x16FromUint32x4Bits > Uint8x16FromInt16x8Bits > Uint8x16FromUint16x8Bits > Uint8x16FromInt8x16Bits > Uint8x16Load > Uint8x16Store > > Bool8x16Check > > LOG=N > BUG=v8:4124 > > Committed: https://crrev.com/3831d41e4ce7b162775732cb6ac1f8139e60aa30 > Cr-Commit-Position: refs/heads/master@{#35213} TBR=bradnelson@chromium.org,gdeepti@chromium.org,titzer@chromium.org,mtrofin@chromium.org,bradnelson@google.com,bmeurer@chromium.org,bbudge@chromium.org # Skipping CQ checks because original CL landed less than 1 days ago.
