Later on you would use -prof-gen-sampling to, among other things, create a map from object code to line number in the source code. This map should be a superset of data you are looking for, which is instantiation count for templates. For templates that don't end up with any object code (meta-functions) I think you would find no instantiations in the map, whereas you might still find that the compiler evaluated the meta-function many times with your warning based approach. I guess it depends on what you are looking for.
Metafunction instantiations are my primary concern.
My own interest is that I would like to do performance profiling and tuning of template instantiated code with VTune. It looks like these compiler options in icc are more well suited to that than the static information you are looking for.
Yep. Oh well.
Is there a way to write a meta-function that implements a counter?
There is no legal way to implement such a counter, AFAIK. There are illegal ways, though. In Christ, Steven Watanabe
