Update.

2000-07-29  Greg McGary  <greg@mcgary.org>

	* 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'.
	* sysdeps/generic/segfault.c (ADVANCE_STACK_FRAME): Wrap bounds
	around return value.
	(catch_segfault): Qualify frame-pointer chain and return address
	pointers as __unbounded.  Wrap bounds around variable `current'.
	* sysdeps/i386/backtrace.c (struct layout): Make pointers __unbounded.
	(ADVANCE_STACK_FRAME): Wrap bounds around return value.
	* sysdeps/powerpc/backtrace.c (struct layout): Make pointers __unbounded.
	(__backtrace): Qualify frame-pointer chain and return address
	pointers as __unbounded.  Wrap bounds around variable `current'.

	* sysdeps/i386/addmul_1.S: s2_limb is scalar so remove bounds check.
	* sysdeps/i386/mul_1.S: Likewise.
	* sysdeps/i386/submul_1.S: Likewise.
	* sysdeps/i386/i586/addmul_1.S: Likewise.
	* sysdeps/i386/i586/mul_1.S: Add bounds checks.
	* sysdeps/i386/i586/submul_1.S: Likewise.
