  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
  50. #include <sys/types.h> // for size_t
  51. #include <new> // for nothrow_t
  52. static char m; // some dummy memory so new doesn't return NULL.
  53. void* operator new(size_t size) { return &m; }
