WebAssembly SIMD load instructions - WebAssembly

Load and load lane

load: Loads a v128 value interpretation from a given heap address.
load8_lane: Loads a single value from a given heap address into the specified lane of a v128 i8x16 value interpretation.
load16_lane: Loads a single value from a given heap address into the specified lane of a v128 i16x8 value interpretation.
load32_lane: Loads a single value from a given heap address into the specified lane of a v128 i32x4 value interpretation.
load64_lane: Loads a single value from a given heap address into the specified lane of a v128 i64x2 value interpretation.

load8x8_s: Loads eight 8-bit integers from a given heap address and sign extends each one to a 16-bit lane, outputting a v128 i16x8 value interpretation.
load8x8_u: Loads eight 8-bit integers from a given heap address and zero extends each one to a 16-bit lane, outputting a v128 i16x8 value interpretation.
load16x4_s: Loads four 16-bit integers from a given heap address and sign extends each one to a 32-bit lane, outputting a v128 i32x4 value interpretation.
load16x4_u: Loads four 16-bit integers from a given heap address and zero extends each one to a 32-bit lane, outputting a v128 i32x4 value interpretation.
load32x2_s: Loads two 32-bit integers from a given heap address and sign extends each one to a 64-bit lane, outputting a v128 i64x2 value interpretation.
load32x2_u: Loads two 32-bit integers from a given heap address and zero extends each one to a 64-bit lane, outputting a v128 i64x2 value interpretation.

load8_splat: Loads a single value from a given heap address into all lanes of a v128 i8x16 value interpretation.
load16_splat: Loads a single value from a given heap address into all lanes of a v128 i16x8 value interpretation.
load32_splat: Loads a single value from a given heap address into all lanes of a v128 i32x4 value interpretation.
load64_splat: Loads a single value from a given heap address into all lanes of a v128 i64x2 value interpretation.

load32_zero: Loads a single value from a given heap address into the first lane of a v128 i32x4 value interpretation, and initializes the other lanes to 0.
load64_zero: Loads a single value from a given heap address into the first lane of a v128 i64x2 value interpretation, and initializes the other lane to 0.
