Just fyi: the cxx compiler has verbose template instantiation mode.

Ingenious, you are automatically inserting a compile time error into every basic block of the template code to be profiled, compiling the translation unit and counting how many error are generated for each template to get a count of how many times the compiler tries (and fails) to instantiate the template.
Actually it only generates warnings. Otherwise, the compiler is liable to stop before it finishes compiling everything.
There may be a more direct way to extract this information with VTune related profiling features provided in icc. I'll follow up and let you know.
Ok. It would be great if compilers supported this directly.
