  33 // When you are porting perftools to a new compiler or architecture
  34 // (win64 vs win32) for instance, you'll need to change the mangled
  35 // symbol names for operator new and friends at the top of
  36 // patch_functions.cc.  This file helps you do that.
  37 //
  38 // It does this by defining these functions with the proper signature.
  39 // All you need to do is compile this file and the run dumpbin on it.
  40 // (See http://msdn.microsoft.com/en-us/library/5x49w699.aspx for more
  41 // on dumpbin).  To do this in MSVC, use the MSVC commandline shell:
  42 //    http://msdn.microsoft.com/en-us/library/ms235639(VS.80).aspx)
  43 //
  44 // The run:
  45 //    cl /c get_mangled_names.cc
  46 //    dumpbin /symbols get_mangled_names.obj
  47 //
  48 // It will print out the mangled (and associated unmangled) names of
  49 // the 8 symbols you need to put at the top of patch_functions.cc
