// 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 nullptr.

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() { }
