WebAssembly SIMD load/store instructions.

Load and load lane

• load

  • : Loads all lanes of a v128 value interpretation with values from a given memory address.

  load8_lane

  • : Loads a single value from a given memory address into the specified lane of a v128 i8x16 value interpretation.

  load16_lane

  • : Loads a single value from a given memory address into the specified lane of a v128 i16x8 value interpretation.

  load32_lane

  • : Loads a single value from a given memory address into the specified lane of a v128 i32x4 value interpretation.

  load64_lane

  • : Loads a single value from a given memory address into the specified lane of a v128 i64x2 value interpretation.

Load and extend

• load8x8_s

  • : Loads eight 8-bit integers from a given memory 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 memory 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 memory 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 memory 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 memory 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 memory address and zero extends each one to a 64-bit lane, outputting a v128 i64x2 value interpretation.

Load and splat

• load8_splat

  • : Loads a single value from a given memory address into all lanes of a v128 i8x16 value interpretation.

  load16_splat

  • : Loads a single value from a given memory address into all lanes of a v128 i16x8 value interpretation.

  load32_splat

  • : Loads a single value from a given memory address into all lanes of a v128 i32x4 value interpretation.

  load64_splat

  • : Loads a single value from a given memory address into all lanes of a v128 i64x2 value interpretation.

Load and zero-pad

• load32_zero

  • : Loads a single value from a given memory 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 memory address into the first lane of a v128 i64x2 value interpretation, and initializes the other lane to 0.

Store and store lane

• store

  • : Stores all lanes of a v128 value interpretation at a given memory address.

  store8_lane

  • : Stores a specified lane of a v128 i8x16 value interpretation at a given memory address.

  store16_lane

  • : Stores a specified lane of a v128 i16x8 value interpretation at a given memory address.

  store32_lane

  • : Stores a specified lane of a v128 i32x4 value interpretation at a given memory address.

  store64_lane

  • : Stores a specified lane of a v128 i64x2 value interpretation at a given memory address.
