annotate libinterp/corefcn/interpreter.cc @ 26113:8a15f3bace49

move eval_string inside interpreter/evaluator class * tree_evaluator.h, tree_evaluator.cc (tree_evaluator::eval_string): New functions. * interpreter.h, interpreter.cc (interpreter::eval_string): New functions. Forward to evaluator eval_string functions. * parse.h, oct-parse.yy (eval_string): Deprecate and forward to interpreter eval_string functions. Change all uses. * pt.h, pt.cc (tree::meets_bp_condition): Accept reference to tree_evaluator as argument. Change all uses. (tree::is_breakpoint): Split into separate is_breakpoint and is_active_breakpoint functions. Change all uses.
