cfghooks.c (lv_flush_pending_stmts, [...]): New.
2005-03-30 Mostafa Hagog <mustafa@il.ibm.com> * cfghooks.c (lv_flush_pending_stmts, cfg_hook_duplicate_loop_to_header_edge, extract_cond_bb_edges, lv_adjust_loop_header_phi, lv_add_condition_to_bb): New. * cfghooks.h (cfg_hook_duplicate_loop_to_header_edge, lv_add_condition_to_bb, lv_adjust_loop_header_phi, extract_cond_bb_edges, flush_pending_stmts): New in cfg_hooks structure. (cfg_hook_duplicate_loop_to_header_edge, lv_flush_pending_stmts, extract_cond_bb_edges, lv_adjust_loop_header_phi, lv_add_condition_to_bb): New declarations. * cfgloop.h (duplicate_loop_to_header_edge): Change return type to bool. (loop_version): Declare. * cfgloopmanip.c (cfghooks.h): Include. (duplicate_loop_to_header_edge): Change return type to bool. (loop_version, lv_adjust_loop_entry_edge): Move here. * cfgrtl.c (cfgloop.h): Include. (rtl_verify_flow_info_1): Fix. (rtl_lv_add_condition_to_bb, rtl_extract_cond_bb_edges): New. (rtl_cfg_hooks, cfg_layout_rtl_cfg_hook): Add hooks to initialization. * tree-cfg.c (tree_lv_adjust_loop_header_phi, tree_lv_add_condition_to_bb): New. (tree_cfg_hooks): Add new hooks to initialization. * tree-ssa-loop-manip.c (lv_adjust_loop_header_phi, lv_adjust_loop_entry_edge, tree_ssa_loop_version): Remove. From-SVN: r97481
