Hi Andrew,

I have merged this in and tested it on the RTSM model which shows an appreciable performance gain on a range of benchmarks.

I have also briefly scanned the > 4000 lines of diffs.

One question I had was the following

+  ins_pipe(pipe_class_default);
+%}
+// BEGIN This section of the file is automatically generated. Do not edit --------------
+
+

Is the section in question in fact automatically generated? And if so where is the tool to generate it?

Otherwise it all looks good to me, please push.

Thanks for this,
Ed.
