My (humble) suggestion would be to start with the compiler builtins, rather than by writing assembler. My understanding is that gcc >= 4.1 on virtually all platforms and the Intel compiler have compatible sets of builtins, and the Microsoft compiler has something equivalent. I don't know about the other Boost-supported compilers - can anyone fill in the gaps? The biggest hole that this would leave is gcc < 4.1; what's the policy about ongoing support for older compilers?
In the working version (still in my machine) gcc builtins will be used for gcc > 4.1, but I need asm implementations for gcc < 4.1 (Intel + PowerPC).
