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.
