e/Jump threading

Information
has gloss	eng: In computing, jump threading is a compiler optimization. In this pass, conditional jumps in the code that branch to identical or inverse tests are detected, and can be "threaded" through a second conditional test. This is easily done in a single pass through the program, following acyclic chained jumps until you arrive at a fixed point.
