The Code Generation Phase occurs when a programmer employs CHECK blocks in their program. After the Code Generation Phase comes to the Parse Tree Reconstruction Phase, note that the above two-phase can be skipped if the programmer does not employ code generators.

Finally, we have the Execution phase or the run phase. The interpreter takes the parse tree from the compiler or the code generator and then executes it.
