From d793732c70a447d8c5b075a62d6483c00e12ee24 Mon Sep 17 00:00:00 2001 From: dnovillo Date: Fri, 9 Jul 2004 15:12:48 +0000 Subject: * tree-dfa.c (dump_variable): If the variable is a pointer SSA_NAME, also dump its points-to information. * tree-flow.h (struct ptr_info_def): Add field is_dereferenced. (dump_points_to_info_for): Declare. (debug_points_to_info_for): Declare. * tree-optimize.c (init_tree_optimization_passes): Add a second alias analysis pass after DOM2. Move pass_del_pta to a later spot. * tree-ssa-alias.c (compute_points_to_and_addr_escape): Do not create a name tags when we find a dereferenced pointer. Just mark the pointer dereferenced. (collect_points_to_info_for): Move code to clear points-to information to create_name_tags. (create_name_tags): New function. (compute_flow_sensitive_aliasing): Call it. (setup_pointers_and_addressables): Mark type tags for renaming here instead of ... (create_memory_tag): ... here. (merge_pointed_to_info): Do not merge PT_MALLOC attributes. (dump_points_to_info_for): Declare extern. (debug_points_to_info_for): New function. git-svn-id: svn+ssh://gcc.gnu.org/svn/gcc/trunk@84377 138bc75d-0d04-0410-961f-82ee72b054a4 --- gcc/tree-optimize.c | 3 ++- 1 file changed, 2 insertions(+), 1 deletion(-) (limited to 'gcc/tree-optimize.c') diff --git a/gcc/tree-optimize.c b/gcc/tree-optimize.c index 750c7af7b4f..aa65ab93c22 100644 --- a/gcc/tree-optimize.c +++ b/gcc/tree-optimize.c @@ -294,7 +294,6 @@ init_tree_optimization_passes (void) NEXT_PASS (pass_may_alias); NEXT_PASS (pass_tail_recursion); NEXT_PASS (pass_ch); - NEXT_PASS (pass_del_pta); NEXT_PASS (pass_profile); NEXT_PASS (pass_lower_complex); NEXT_PASS (pass_sra); @@ -303,6 +302,7 @@ init_tree_optimization_passes (void) NEXT_PASS (DUP_PASS (pass_redundant_phi)); NEXT_PASS (DUP_PASS (pass_dce)); NEXT_PASS (pass_dse); + NEXT_PASS (DUP_PASS (pass_may_alias)); NEXT_PASS (DUP_PASS (pass_forwprop)); NEXT_PASS (DUP_PASS (pass_phiopt)); NEXT_PASS (pass_ccp); @@ -320,6 +320,7 @@ init_tree_optimization_passes (void) NEXT_PASS (pass_tail_calls); NEXT_PASS (pass_late_warn_uninitialized); NEXT_PASS (pass_warn_function_return); + NEXT_PASS (pass_del_pta); NEXT_PASS (pass_del_ssa); NEXT_PASS (pass_nrv); NEXT_PASS (pass_remove_useless_vars); -- cgit v1.2.3
