octave: libinterp/parse-tree/parse.h annotate

annotate libinterp/parse-tree/parse.h @ 23655:bbcc1e08aaed

improve colon expression construction and avoid possible memory leak Don't allow errors to be thrown during colon expression construction. * pt-colon.h, pt-colon.cc (tree_colon_expression::tree_colon_expression): Construct either two- or three-element expressions. (tree_colon_expression::append): Delete. (tree_colon_expression::line, tree_colon_expression::colum): Delete. * parse.h, oct-parse.in.yy (base_parser::make_colon_expression): New function. (base_parser::finish_colon_expression): Delete. (colon_expr1): Delete non-terminal (tree_colon_expression_type): Delete. (colon_expr): Construct two- or three-element expressions only. (simple_expr): Handle single oper_expr separately here.
