0009 // The StripSymbols transformation implements code stripping. Specifically, it
0010 // can delete:
0011 //
0012 //   * names for virtual registers
0013 //   * symbols for internal globals and functions
0014 //   * debug information
0015 //
0016 // Note that this transformation makes code much less readable, so it should
0017 // only be used in situations where the 'strip' utility would be used, such as
0018 // reducing code size or making it harder to reverse engineer code.
