Function signatures are specified with the <code>signature</code>
|
||
|
|
pseudo-opcode, followed by a simple function signature imitating a
|
||
|
|
C++-mangled function type: <code>F</code> followed by an optional <code>v</code>,
|
||
|
|
then a sequence of <code>i</code>, <code>l</code>, <code>f</code>, and <code>d</code>
|
||
|
|
characters to mark i32, i64, f32, and f64 parameters, respectively;
|
||
|
|
followed by a final <code>E</code> to mark the end of the function
|
||
|
|
signature.
