| // When you are porting perftools to a new compiler or architecture |
| // (win64 vs win32) for instance, you'll need to change the mangled |
| // symbol names for operator new and friends at the top of |
| // patch_functions.cc. This file helps you do that. |
| // |
| // It does this by defining these functions with the proper signature. |
| // All you need to do is compile this file and the run dumpbin on it. |
| // (See http://msdn.microsoft.com/en-us/library/5x49w699.aspx for more |
| // on dumpbin). To do this in MSVC, use the MSVC commandline shell: |
| // http://msdn.microsoft.com/en-us/library/ms235639(VS.80).aspx) |
| // |
| // The run: |
| // cl /c get_mangled_names.cc |
| // dumpbin /symbols get_mangled_names.obj |
| // |
| // It will print out the mangled (and associated unmangled) names of |
| // the 8 symbols you need to put at the top of patch_functions.cc |
| |
| #include <sys/types.h> // for size_t |
| #include <new> // for nothrow_t |
| |
| static char m; // some dummy memory so new doesn't return NULL. |
