+ * Rules (test-bp-inputs, make-test-out): New variables.
+ ($(objpfx)%-bp.out): New rule.
+ ($(objpfx)%.out): Rewrite in terms of new variables.
+
+ * libio/iovswscanf.c (vswscanf): Pass _IO_FILE_plus pointer to
+ internal function that uses vtable.
+ * libio/vsnprintf.c (_IO_vsnprintf): Likewise.
+ * libio/vswprintf.c (_IO_vswprintf): Likewise.
+
+ * malloc/malloc.c (mem2chunk): Define in terms of chunk_at_offset.
+ (malloc_extend_top): Convert brk to chunk using chunk_at_offset.
+ (chunk_align): Likewise.
+
+ * time/asctime.c (ab_day_name, ab_month_name): Rewrite expression
+ in a way that conforms to decl, and avoids spurious bounds violation.
+
+ * sysdeps/arm/frame.h (struct layout): Make pointers __unbounded.
+ * sysdeps/generic/frame.h: Likewise.
+ * sysdeps/generic/backtrace.c (ADVANCE_STACK_FRAME): Wrap bounds
+ around return value.
+ (__backtrace): Qualify frame-pointer chain and return address
+ pointers as __unbounded. Wrap bounds around variable `current'.
