(reset_sched_cycles_in_current_ebb): Also recheck the DFA state in the advancing loop when we have issued issue_rate insns. Backport from mainline 2010-12-22 Andrey Belevantsev <a...@ispras.ru> PR rtl-optimization/45352 PR rtl-optimization/46521 PR rtl-optimization/46522 * sel-sched.c (reset_sched_cycles_in_current_ebb): Recheck the DFA state on the last iteration of the advancing loop. (sel_sched_region_1): Propagate the rescheduling bit to the next block also for empty blocks. Backport from mainline 2010-11-08 Andrey Belevantsev <a...@ispras.ru> PR rtl-optimization/45352 * sel-sched.c (find_best_expr): Do not set pneed_stall when the variable_issue hook is not implemented. (fill_insns): Remove dead variable stall_iterations. (init_seqno_1): Force EBB start for resetting sched cycles on any successor blocks of the rescheduled region. (sel_sched_region_1): Use bitmap_bit_p instead of bitmap_clear_bit. (reset_sched_cycles_in_current_ebb): Add debug printing. New variable issued_insns. Advance state when we have issued issue_rate insns.
