Speed up use-after-scope (v2): rewrite into SSA
2017-01-23 Martin Liska <mliska@suse.cz>
* asan.c (create_asan_shadow_var): New function.
(asan_expand_poison_ifn): Likewise.
* asan.h (asan_expand_poison_ifn): New declaration.
* internal-fn.c (expand_ASAN_POISON): Likewise.
* internal-fn.def (ASAN_POISON): New builtin.
* sanopt.c (pass_sanopt::execute): Expand
asan_expand_poison_ifn.
* tree-inline.c (copy_decl_for_dup_finish): Make function
external.
* tree-inline.h (copy_decl_for_dup_finish): Likewise.
* tree-ssa.c (is_asan_mark_p): New function.
(execute_update_addresses_taken): Rewrite local variables
(identified just by use-after-scope as addressable) into SSA.
