OPTIMIZATIONS
Performs the reverse of inlining. It detects common code parts in the generated code. The Compiler moves the common code to a different place and replaces all occurrences with a JSR to the moved code. At the end of the common code, the Compiler inserts an RTS instruction. The Compiler increases all SP uses by an address size. This optimization takes care of stack allocation, control flow, and of functions having arguments on the stack.
