The main interpreted instruction type. This is what is returned by InstructionIter, but it is not what is stored internally. For that, see InstructionInternal.

Variants

GetLocal(u32)

Push a local variable or an argument from the specified depth.

SetLocal(u32)

Pop a value and put it in at the specified depth.

TeeLocal(u32)

Copy a value to the specified depth.

Br(Target)

Similar to the Wasm ones, but instead of a label depth they specify direct PC.

BrIfEqz(Target)BrIfNez(Target)BrTable(BrTargets<'a>)

br_table [t1 t2 t3 .. tn] tdefault

Pops the value from the stack. Then this value is used as an index to the branch table.

However, the last target represents the default target. So if the index is greater than length of the branch table, then the last index will be used.

Validation ensures that there should be at least one target.
