Correct, but this pseudo-language is not portable between architectures. > Therefore, is it possible to re-write the above to a cross-compilable form? The assembly in the Go distribution is already cross-compilable, but looking at your example you are not concerned whether the assembly is cross-compilable or not (that depends on the toolchain, and not on the assembly code), but you want the assembly to be portable between architectures. Apart from the most trivial of cases, this is not possible. Different targets use different instructions and different registers. The Go assembler uses the same *syntax* on every architecture, so it can be parsed and processed by a single program, however the assembly code required for each target is very different. -- Aram Hăvărneanu -- You received this message because you are subscribed to the Google Groups "golang-nuts" group.
