The new code is appended to the provided list of instructions, which may be at a code generation position unrelated to the receiver. The extracted outer variable will be written to the provided target register.
Return
The L2ReadBoxedOperand holding the outer value.
Parameters
instruction
The instruction that produced the function. Its operation is the receiver.
function
The register holding the function at the code generation point.
outer
