Dhrystone definition

A short synthetic benchmark program by Reinhold Weicker , , intended to be representative of system (integer) programming. It is available in ADA, Pascal and C.
The current version is Dhrystone 2.1. The author says, "Relying on MIPS V1.1 (the result of V1.1) numbers can be hazardous to your professional health."
Due to its small size, the memory system outside the cache is not tested. Compilers can too easily optimise for Dhrystone. String operations are somewhat over-represented.
