| Pass | Description |
|---|---|
| 1 | Constants subexpressions elimination (CSE) true, false, null, etc. Optimize series of ADD_STRING / ADD_CHAR Convert CAST(IS_BOOL,x) into BOOL(x) Convert INIT_FCALL_BY_NAME + DO_FCALL_BY_NAME into DO_FCALL |
| 2 | Convert constant operands to expected types Convert conditional JMP with constant operands Optimize static BRK and CONT |
| 3 | Convert $a = $a + expr into $a += expr Convert $a++ into ++$a Optimize series of JMP |
| 4 | PRINT and ECHO optimization (defunct) |
| 5 | Block Optimization - most expensive pass Performs many different optimization patterns based on control flow graph (CFG) |
| 9 | Optimize register allocation (allows re-usage of temporary variables) |
| 10 | Remove NOPs |
