New Revision: 192375

URL: http://gcc.gnu.org/viewcvs?root=gcc&view=rev&rev=192375
Log:
	* Makefile.in (GTFILES): Add $(srcdir)/asan.c.
	* asan.c (shadow_ptr_types): New variable.
	(report_error_func): Change is_store argument to bool, don't append
	newline to function name.
	(PROB_VERY_UNLIKELY, PROB_ALWAYS): Define.
	(build_check_stmt): Change is_store argument to bool.  Emit GIMPLE
	directly instead of creating trees and gimplifying them.  Mark
	the error reporting function as very unlikely.
	(instrument_derefs): Change is_store argument to bool.  Use
	int_size_in_bytes to compute size_in_bytes, simplify size check.
	Use build_fold_addr_expr instead of build_addr.
	(transform_statements): Adjust instrument_derefs caller.
	Use gimple_assign_single_p as stmt test.  Don't look at MEM refs
	in rhs2.
	(asan_init_shadow_ptr_types): New function.
	(asan_instrument): Don't push/pop gimplify context.
	Call asan_init_shadow_ptr_types if not yet initialized.
	* asan.h (ASAN_SHADOW_SHIFT): Adjust comment.
