Bases: YulStatementAbc
Leave statement exits the execution of the current function.
It is analogous to the return statement in Solidity, except that it does not accept any arguments to be returned as a return value.
Instead, it returns the last-assigned values to the return variables of the function (or default values if none were assigned).
Example
assembly {
function foo() {
leave
// execution stops here
}
foo()
// execution continue here
}
