As long as "modest" means most of the speedup, agreed. I'm arguing that it is easier to get most of the increase by having a good instruction set and targeting improvements at that rather than adding fancy new instructions and hoping the world catches up. Linus wrote about the recompilation issue, and that is a big problem. The time taken to add new instructions to compilers and for developers to upgrade to those compilers is often several years.

Even when compilers are available, many developers decide not to upgrade their existing projects for all sorts of valid reasons. In the embedded space large and long running projects may never upgrade to a new compiler as it is just too risky - this despite the much higher importance of getting the smallest (or fastest) code compared to desktops.

>Having one or two omissions from your original instruction set is not a huge problem.

While fixing is certainly feasible (and most architectures do it), in my experience it is very expensive. Similar to fixing software bugs, the overall cost of fixing those omissions is many times larger than adding them early on. Of course an end user often doesn't see that cost, but that doesn't mean it wasn't there. It is a huge problem for everybody else.

That's the right thing to do if most OS calls are made from shared libaries/DLLs - upgrading them would improve many legacy applications without needing recompilation.

Yes, the x87 unit was disliked since the start, so people jump onto a better solution.

It can go wrong as well - early XScales had performance issues which led to several major design wins being lost.
