<p>Ordinary instructions are encoded with the WebAssembly mnemonics as
|
||
|
|
listed at:
|
||
|
|
<a href="https://github.com/WebAssembly/design/blob/master/BinaryEncoding.md">https://github.com/WebAssembly/design/blob/master/BinaryEncoding.md</a>.
|
||
|
|
</p>
|
||
|
|
<p>Opcodes are written directly in the order in which they are encoded,
|
||
|
|
without going through an intermediate sexp-style expression as in the
|
||
|
|
<code>was</code> format.
|
||
|
|
</p>
|
||
|
|
<p>For “typed” opcodes (block, if, etc.), the type of the block is
|
||
|
|
specified in square brackets following the opcode: <code>if[i]</code>,
|
||
|
|
<code>if[]</code>.
