2017-11-24Factor out division by squaresJackson Woodruff6-30/+289
This patch implements the some of the division optimizations discussed in https://gcc.gnu.org/bugzilla/show_bug.cgi?id=71026. The division reciprocal optimization now handles divisions by squares: x / (y * y) -> x * (1 / y) * (1 / y) This requires at least one more division by y before it triggers - the 3 divisions of (1/ y) are then CSEd into a single division. Overall this changes 1 division into 1 multiply, which is generally much faster. 2017-11-24 Jackson Woodruff <jackson.woodruff@arm.com> gcc/ PR tree-optimization/71026 * tree-ssa-math-opts (is_division_by_square, is_square_of): New.
