(loop...)
Creates a code block that can be used to loop execution, repeating the same inner code a number of times.
When the instruction comes to the end of the loop it will not automatically move to the top again.
You have to manually branch to the top of the loop using either the br
or br_if
instructions.
Syntax
(loop $label (param...) (result...))
loop $label (param...) (result...)
...
end
Parameters
$label Optional
The name of the loop. This is used with the branch instructions br
and br_if
.
Each code block, both loop
and block
, are given an index. The inner most code block
will have index 0 and its parent will have index 1, and so on.
Example
loop $name_of_loop_section
br $name_of_loop_section
end
