This is more of a Visual Studio (2012) question. Basically I've got a few functions written in x64 assembly. They are defined as extern "C" in the c++ source files in which they are used. They are faster then their c++ equivalent but not by a huge amount (because c++ equivalent functions are inlined and that saves call time for short functions). Is there any way I can get the linker to inline them (inline keyword doesn't seem to work)?
