Sebastian Pop <spop at gcc dot gnu.org> changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |spop at gcc dot gnu.org --- Comment #7 from Sebastian Pop <spop at gcc dot gnu.org> --- I think the patch is ok. If in the future we want to handle those other loops, we will need to compute the loop bound in add_loop_constraints() with a check for whether the stmt is dominated by the exit or not. Here is what we do today for all stmts in the loop: tree nb_iters = number_of_latch_executions (loop); if (TREE_CODE (nb_iters) == INTEGER_CST) { /* loop_i <= cst_nb_iters */ the constraint '<=' on statements' iteration domains implies that the loop should be under a do-while form.
