Bytes

[0xfc, 0x0e]

Prefix

0xFC bulk-memory / saturating conversions / table extension space

Encoding

0xFC 0x0E <dst:u32-leb128> <src:u32-leb128>

Immediates

Proposal

bulk-memory

Browser Support

Feature-detect runtime support before executing examples.

Validation Rules

Operands and result types must match the instruction signature.
The instruction must appear in a valid structured control context.

Common Mistakes

Using the instruction with the wrong operand type.
Forgetting that WAT validation is stack-typed.

Example

(func $example
  ;; table.copy example
)
