ykcbf

A collection of simple BF interpreters:

• bf_base.c: the base BF interpreter upon which others are built. This deliberately does not do any preprocessing/optimisation of the BF program.
• yk_simple_yk.c: the minimum changes from bf_base.c to make the BF interpreter run under yk.
• yk_simple2_yk.c: adds some simple trace optimisations to yk_simple_yk.c.
