2000-07-26 Greg McGary <greg@mcgary.org>
* Makeconfig (+link-bounded, link-libc-bounded,
link-extra-libs-bounded): New variables.
(built-program-cmd): Omit $(run-program-prefix) for static BP tests.
* Makerules (do-tests-clean, common-mostlyclean): Remove BP test files.
* Rules (tests-bp.out): New variable.
(tests): Conditionally add BP tests.
(binaries-bounded): Add variable and associated rule.
* csu/Makefile [build-bounded] (extra-objs, install-lib):
Move conditional stuff after place where condition is defined.
* malloc/malloc.c (bp-checks.h): Add #include.
(mem2chunk, chunk_at_offset, bin_at): Wrap BOUNDED_1 around expression.
(_bin_at): Add unbounded version of bin_at.
(IAV, chunk_alloc): Use unbounded _bin_at.
(mALLOc, rEALLOc, chunk_realloc, mEMALIGn, cALLOc,
chunk2mem_check, realloc_check, malloc_starter, malloc_atfork):
Wrap BOUNDED_N around return value.
(chunk_realloc): Adjust oldsize once.
* sysdeps/generic/bp-checks.h (__memchr): Remove incorrect decl.
(__ubp_memchr): Add correct decl.
(_CHECK_STRING): Use __ubp_memchr.
* sysdeps/alpha/memchr.S [!__BOUNDED_POINTERS__] (__ubp_memchr):
New alias for unbounded-pointer __memchr.
* sysdeps/i386/memchr.S: Likewise.

* sysdeps/sparc/sparc64/memchr.S: Likewise.
* sysdeps/vax/memchr.s: Likewise.
* sysdeps/i386/strtok.S: Fix bounds checks to pass tests.
(SAVE_PTR): New macro. (save_ptr): Expand size as BP.
(strtok): Don't bother to write into SAVE_PTR when returning NULL.
* sysdeps/i386/i686/strtok.S: Likewise.
* sysdeps/i386/bp-asm.h (RETURN_BOUNDED_POINTER,
RETURN_NULL_BOUNDED_POINTER): Use %ecx as the scratch register.
* sysdeps/i386/bits/string.h [!__BOUNDED_POINTERS__]: Disable inlines.
* sysdeps/i386/i486/bits/string.h [!__BOUNDED_POINTERS__]: Likewise.
