Bytes

[0xfc, 0x0c]

Prefix

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

Encoding

0xFC 0x0C <elemidx:u32-leb128> <tableidx:u32-leb128>

Immediates

elemidx: u32-leb128
tableidx: u32-leb128

Category

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.init example
)
