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. |
