+These programs come from the embenchen benchmark suite.  The source
+code and Makefiles from which they were built can be found in
+https://github.com/lars-t-hansen/embenchen/, in the src directory.
+
+Invariably, the Makefiles were set up with -DJITTEST (see comments in
+those files), to configure the programs with very small input problems
+that will run to completion in many configurations even on slower
+systems.
+
+(Should that repo not be available, it should be possible to piece
+together sources from https://github.com/kripken/embenchen and
+https://github.com/kripken/emscripten/.)
