(struct variable_info): Add is_restrict_var flag and ruid member. (new_var_info): Initialize is_restrict_var. (make_constraint_from_restrict): Likewise. (create_variable_info_for): Exclude restricts from global vars from new handling. (intra_create_variable_infos): But not those from parameters. (visit_loadstore): New function. (maybe_set_dependence_info): Likewise. (compute_dependence_clique): Likewise. (compute_may_aliases): Call compute_dependence_clique. * tree-data-ref.c (dr_analyze_indices): Copy dependence info to fake MEM_REF. (dr_may_alias_p): Use recorded dependence info to answer alias query. * tree-core.h (struct tree_base): Add clique, base struct in union. * tree.h (MR_DEPENDENCE_CLIQUE): New macro. (MR_DEPENDENCE_BASE): Likewise. * tree-inline.h (dependence_hasher): New hash-map kind. (struct copy_body_data): Add dependence_map pointer. * gimple-fold.c (maybe_canonicalize_mem_ref_addr): Avoid throwing away dependence info. * tree-streamer-in.c (unpack_value_fields): Stream dependence info. * tree-streamer-out.c (streamer_pack_tree_bitfields): Likewise. * gcc.dg/tree-ssa/restrict-5.c: New testcase. git-svn-id: svn+ssh://gcc.gnu.org/svn/gcc/trunk@218004 138bc75d-0d04-0410-961f-82ee72b054a4 --- gcc/function.h | 3 +++ 1 file changed, 3 insertions(+) (limited to 'gcc/function.h') diff --git a/gcc/function.h b/gcc/function.h index 3a6305ca700..a93090164ee 100644 --- a/gcc/function.h +++ b/gcc/function.h @@ -589,6 +589,9 @@ struct GTY(()) function { a string describing the reason for failure. */ const char * GTY((skip)) cannot_be_copied_reason; + /* Last assigned dependence info clique. */ + unsigned short last_clique; + /* Collected bit flags. */ /* Number of units of general registers that need saving in stdarg -- cgit v1.2.1
