Wrong options. -DINLINE_AMD is what you want. But then you are doing the wrong thing anyway, as intel doesn't produce 64 bit code. You will do better to either get a 64 bit version of MSVC, or install/build GCC for the AMD64 architecture... However, the inlineamd.h file might not work with intel for 32 bit architectures. It won't know about 64 bit bsf/bsr instructions... >> >>Has anyone else ever seen that? > >It may mean that the compiler generated better assembly than you did. > >It may also mean that you pulled in the wrong assembly.
