From ed7e22069d2345aced81f8cc3f1dbfb258ba05e4 Mon Sep 17 00:00:00 2001 From: steven Date: Mon, 13 Aug 2012 21:02:19 +0000 Subject: * tree-ssa-pre.c (do_regular_insertion): Add FIXME markers at points of potentially huge memset overhead. (do_partial_partial_insertion): Likewise. * cfgexpand.c (gimple_expand_cfg): Use XCNEWVEC instead of xcalloc. * tree-vrp.c (find_assert_locations): Use XNEWVEC instead of XCNEWVEC for arrays to be filled by pre_and_rev_post_order_compute. Allocate the right number of slots, not that number plus NUM_FIXED_BLOCKS. * tree-ssa-reassoc.c (init_reassoc): Likewise. * cfganal.c (dfs_enumerate_from): Use XNEWVEC instead of XCNEWVEC for array used as stack. * tree-ssa-sccvn.c (init_scc_vn): Use XNEWVEC instead of XCNEWVEC for arrays to be filled by pre_and_rev_post_order_compute. * cfgloopmanip.c (find_path): Use XNEWVEC instead of XCNEWVEC for array to be filled by dfs_enumerate_from. (remove_path): Likewise. (duplicate_loop_to_header_edge): Use XNEWVEC instead of XCNEWVEC for array of loops that is filled on the next lines. * cfgloop.c (get_loop_body): Use XNEWVEC instead of XCNEWVEC for array of basic blocks to be returned. (get_loop_body_in_dom_order): Likewise. (get_loop_body_in_bfs_order): Likewise. * tree-ssa-loop-manip.c (loop_renamer_obstack): New static obstack for all bitmaps used for rewriting into loop-closed SSA form. (add_exit_phis_var): Allocate the def bitmap on it. Clear the livein bitmap at the end to release a lot of memory. (add_exit_phis): Allocate the exits bitmap on the new obstack. (get_loops_exits): Allocate the exits bitmap on the new obstack. (find_uses_to_rename_use): Allocate a use_blocks bitmap if ver is seen for the first time. (find_uses_to_rename): Add "???" for why the whole function must be re-scanned if changed_bbs is empty. (rewrite_into_loop_closed_ssa): Allocate bitmaps on the new obstack. Use XNEWVEC to allocate the use_blocks array. Initialize the new obstack, and free it at the end. Remove loop over all SSA names. (check_loop_closed_ssa_stmt): Look only at SSA_OP_USE operands. * tree-cfg.c (move_sese_region_to_fn): Use XNEWVEC instead of xcalloc to allocate edge_pred and edge_flag arrays. git-svn-id: svn+ssh://gcc.gnu.org/svn/gcc/trunk@190359 138bc75d-0d04-0410-961f-82ee72b054a4 --- gcc/cfgloop.c | 6 +++--- 1 file changed, 3 insertions(+), 3 deletions(-) (limited to 'gcc/cfgloop.c') diff --git a/gcc/cfgloop.c b/gcc/cfgloop.c index 0c51682897e..dd75be668e3 100644 --- a/gcc/cfgloop.c +++ b/gcc/cfgloop.c @@ -805,7 +805,7 @@ get_loop_body (const struct loop *loop) gcc_assert (loop->num_nodes); - body = XCNEWVEC (basic_block, loop->num_nodes); + body = XNEWVEC (basic_block, loop->num_nodes); if (loop->latch == EXIT_BLOCK_PTR) { @@ -865,7 +865,7 @@ get_loop_body_in_dom_order (const struct loop *loop) gcc_assert (loop->num_nodes); - tovisit = XCNEWVEC (basic_block, loop->num_nodes); + tovisit = XNEWVEC (basic_block, loop->num_nodes); gcc_assert (loop->latch != EXIT_BLOCK_PTR); @@ -904,7 +904,7 @@ get_loop_body_in_bfs_order (const struct loop *loop) gcc_assert (loop->num_nodes); gcc_assert (loop->latch != EXIT_BLOCK_PTR); - blocks = XCNEWVEC (basic_block, loop->num_nodes); + blocks = XNEWVEC (basic_block, loop->num_nodes); visited = BITMAP_ALLOC (NULL); bb = loop->header; -- cgit v1.2.1
