This is an intermediate step. We'll replace CPS bit by bit. If it turns out to be a terrible idea we can just revert. * module/Makefile.am (TREE_IL_LANG_SOURCES): Remove compile-cps.scm. (CPS_LANG_SOURCES): Remove arities.scm. * module/language/cps/arities.scm: Remove. * module/language/tree-il/compile-cps.scm: Remove. * module/language/tree-il/spec.scm: Remove use of compile-cps.scm. * module/language/cps/compile-bytecode.scm: Remove use of arities.scm. Instead, incoming terms are expected to call their continuations with the correct number of arguments.
