Instructions

Instructions are syntactically distinguished into plain and structured instructions.

\[\begin{split}\begin{array}{llclll} \def\mathdef3103#1{{}}\mathdef3103{instruction} & \href{../text/instructions.html#text-instr}{\mathtt{instr}}_I &::=& \mathit{in}{:}\href{../text/instructions.html#text-plaininstr}{\mathtt{plaininstr}}_I &\Rightarrow& \mathit{in} \\ &&|& \mathit{in}{:}\href{../text/instructions.html#text-blockinstr}{\mathtt{blockinstr}}_I &\Rightarrow& \mathit{in} \\ \end{array}\end{split}\]

In addition, as a syntactic abbreviation, instructions can be written as S-expressions in folded form, to group them visually.

Labels

Structured control instructions can be annotated with a symbolic label identifier. They are the only symbolic identifiers that can be bound locally in an instruction sequence. The following grammar handles the corresponding update to the identifier context by composing the context with an additional label entry.

\[\begin{split}\begin{array}{llcllll} \def\mathdef3103#1{{}}\mathdef3103{label} & \href{../text/instructions.html#text-label}{\mathtt{label}}_I &::=& v{:}\href{../text/values.html#text-id}{\mathtt{id}} &\Rightarrow& v, \{\href{../text/conventions.html#text-context}{\mathsf{labels}}~v\} \href{../syntax/conventions.html#notation-compose}{\oplus} I & (\mathrel{\mbox{if}} v \notin I.\href{../text/conventions.html#text-context}{\mathsf{labels}}) \\ &&|& v{:}\href{../text/values.html#text-id}{\mathtt{id}} &\Rightarrow& v, \{\href{../text/conventions.html#text-context}{\mathsf{labels}}~v\} \href{../syntax/conventions.html#notation-compose}{\oplus} (I \href{../syntax/conventions.html#notation-replace}{\mathrel{\mbox{with}}} \href{../text/conventions.html#text-context}{\mathsf{labels}}[i] = \epsilon) & (\mathrel{\mbox{if}} I.\href{../text/conventions.html#text-context}{\mathsf{labels}}[i] = v) \\ &&|& \epsilon &\Rightarrow& \epsilon, \{\href{../text/conventions.html#text-context}{\mathsf{labels}}~(\epsilon)\} \href{../syntax/conventions.html#notation-compose}{\oplus} I \\ \end{array}\end{split}\]

Note

The new label entry is inserted at the beginning of the label list in the identifier context. This effectively shifts all existing labels up by one, mirroring the fact that control instructions are indexed relatively not absolutely.

If a label with the same name already exists, then it is shadowed and the earlier label becomes inaccessible.

Control Instructions

Structured control instructions can bind an optional symbolic label identifier. The same label identifier may optionally be repeated after the corresponding \(\mathtt{end}\) or \(\mathtt{else}\) keywords, to indicate the matching delimiters.

Their block type is given as a type use, analogous to the type of functions. However, the special case of a type use that is syntactically empty or consists of only a single result is not regarded as an abbreviation for an inline function type, but is parsed directly into an optional value type.

Note

The side condition stating that the identifier context \(I'\) must only contain unnamed entries in the rule for \(\href{../text/modules.html#text-typeuse}{\mathtt{typeuse}}\) block types enforces that no identifier can be bound in any \(\href{../text/types.html#text-functype}{\mathtt{param}}\) declaration for a block type.

Memory Instructions

The offset and alignment immediates to memory instructions are optional. The offset defaults to \(\mathtt{0}\), the alignment to the storage size of the respective memory access, which is its natural alignment. Lexically, an \(\href{../text/instructions.html#text-memarg}{\mathtt{offset}}\) or \(\href{../text/instructions.html#text-memarg}{\mathtt{align}}\) phrase is considered a single keyword token, so no white space is allowed around the \(\def\mathdef3263#1{\mbox{‘}\mathtt{#1}\mbox{’}}\mathdef3263{=}\).

Folded Instructions

Instructions can be written as S-expressions by grouping them into folded form. In that notation, an instruction is wrapped in parentheses and optionally includes nested folded instructions to indicate its operands.

In the case of block instructions, the folded form omits the \(\def\mathdef3742#1{\mbox{‘}\mathtt{#1}\mbox{’}}\mathdef3742{end}\) delimiter. For \(\href{../syntax/instructions.html#syntax-instr-control}{\mathsf{if}}\) instructions, both branches have to be wrapped into nested S-expressions, headed by the keywords \(\def\mathdef3743#1{\mbox{‘}\mathtt{#1}\mbox{’}}\mathdef3743{then}\) and \(\def\mathdef3744#1{\mbox{‘}\mathtt{#1}\mbox{’}}\mathdef3744{else}\).

The set of all phrases defined by the following abbreviations recursively forms the auxiliary syntactic class \(\href{../text/instructions.html#text-foldedinstr}{\mathtt{foldedinstr}}\). Such a folded instruction can appear anywhere a regular instruction can.

Note

For example, the instruction sequence

\[\mathtt{(local.get~\$x)~(i32.const~2)~i32.add~(i32.const~3)~i32.mul}\]

can be folded into

\[\mathtt{(i32.mul~(i32.add~(local.get~\$x)~(i32.const~2))~(i32.const~3))}\]

Folded instructions are solely syntactic sugar, no additional syntactic or type-based checking is implied.

Expressions

Expressions are written as instruction sequences. No explicit \(\def\mathdef3774#1{\mbox{‘}\mathtt{#1}\mbox{’}}\mathdef3774{end}\) keyword is included, since they only occur in bracketed positions.
