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.
