Willing to help on these implementations? We also need to write our own versions to avoid license issues with the original Apache implementation (basically we need our implementation of gcc Intel & PowerPC asm versions).
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?
