| 9 | // The StripSymbols transformation implements code stripping. Specifically, it |
| 10 | // can delete: |
| 11 | // |
| 12 | // * names for virtual registers |
| 13 | // * symbols for internal globals and functions |
| 14 | // * debug information |
| 15 | // |
| 16 | // Note that this transformation makes code much less readable, so it should |
| 17 | // only be used in situations where the 'strip' utility would be used, such as |
| 18 | // reducing code size or making it harder to reverse engineer code. |
