genmatch.c (struct expr): Add force_single_use flag.
2015-07-09 Richard Biener <rguenther@suse.de>
* genmatch.c (struct expr): Add force_single_use flag.
(expr::expr): Add copy constructor.
(capture_info::walk_match): Gather force_single_use captures.
(expr::gen_transform): Use possibly NULLified sequence.
(dt_simplify::gen): Apply single-use restrictions by NULLifying
seq if any constrained expr is not single-use.
(parser::parse_expr): Refactor to allow multiple flags. Handle
's' flag to force an expression have a single-use if the pattern
simplifies to more than one statement.
* match.pd: Convert most single_use conditionals to :s flags.
