-	PR tree-optimization/94015
-	* tree-ssa-strlen.c (count_nonzero_bytes): Split portions of the
-	function where EXP is address of the bytes being stored rather than
-	the bytes themselves into count_nonzero_bytes_addr.  Punt on zero
-	sized MEM_REF.  Use VAR_P macro and handle CONST_DECL like VAR_DECLs.
-	Use ctor_for_folding instead of looking at DECL_INITIAL.  Punt before
-	calling native_encode_expr if host or target doesn't have 8-bit
-	chars.  Formatting fixes.
-	(count_nonzero_bytes_addr): New function.
-
-	* gcc.dg/pr94015.c: New test.
