forth_coremark provides a port of CoreMark benchmark to Forth program language. It allows to benchmark Forth compilers vs. Forth compilers and vs. C compilers on the same machine. Furthermore, forth_coremark allows to benchmark Stack machines programmed in Forth vs. CPUs programmed in C.

I wrote forth_coremark using ANS94 to allow an easy porting and optimization on as much as possible Forth environments and Stack machines.
