- // 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.
- void* operator new(size_t size) { return &m; }
- void operator delete(void* p) throw() { }
- void* operator new[](size_t size) { return &m; }
- void operator delete[](void* p) throw() { }
- void* operator new(size_t size, const std::nothrow_t&) throw() { return &m; }
- void operator delete(void* p, const std::nothrow_t&) throw() { }
- void* operator new[](size_t size, const std::nothrow_t&) throw() { return &m; }
- void operator delete[](void* p, const std::nothrow_t&) throw() { }
