re PR middle-end/79665 (gcc's signed (x*x)/200 is slower than clang's)
PR middle-end/79665
* internal-fn.c (get_range_pos_neg): Moved to ...
* tree.c (get_range_pos_neg): ... here. No longer static.
* tree.h (get_range_pos_neg): New prototype.
* expr.c (expand_expr_real_2) <case TRUNC_DIV_EXPR>: If both arguments
are known to be in between 0 and signed maximum inclusive, try to
expand both unsigned and signed divmod and use the cheaper one from
those.
