Yeah, using NASM is no issue at all, but inline ASM would be nice.
Thanks in advance.

As a developer, I can say, that ICC do not disable any optimizations, when compiling for AMD. Moreover, you can compile code on Intel machine, but execute it on AMD, so ICC cannot do anything bad, even if it wanted. But, of course, ICC supports more optimizations for features "unsupported" in AMD, and this can affect performance, but this is a rare case. If you write normal code (not system-specific, like SVM or smth else) - ICC is a good choice even for AMD platform.
