 JITs is that their optimizers are much easier to write. Because a tracing JIT
 produces only linear pieces of code without control flow joins, many
 optimization passes on traces can have a very simple structure. They often
-consist of one forward pass through the trace, discarding and replacing
-operations in the trace by simpler ones as they walk along it. This makes
-optimization of traces very similar to symbolic execution. Many

 difficult problems in traditional optimizers become tractable if the optimizer
 does not need to deal with control flow merges.
