Assumptions like loop equivalence can fall apart when considering the CFG ( control flow graph) interpretation versus ... languages it helps to write your code as straightforward as possible ...

Some applications are so inherently complicated that it is difficult to dig through the many layers of connected algorithms to expose the parts of the code ripe for optimization. This makes them a ...

Recent compilers attempt to prevent this by emitting additional checks before dereferencing code pointers, thus placing restrictions on the control flow graph. This makes exploitation more difficult.
