+Each module compiled with -fhpc declares an initialisation function of
+the form `hpc_init_<module>()`, which is emitted into the _stub.c file
+and annotated with __attribute__((constructor)) so that it gets
+executed at startup time.
+
+The function's purpose is to call hs_hpc_module to register this
+module with the RTS, and it looks something like this:
+
+static void hpc_init_Main(void) __attribute__((constructor));
