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.
