Code duplication can also mean more errors and a lot more work for porters. You'll also see plenty of other examples in popular open-source projects such as the Linux and FreeBSD kernel. The reduction in amount of duplication is significant.

For example: For SPARCv9 for example, the macro system generates 138 functions from only the 25 or so the developer provides. To top it off, this would work across memory models as well.
