*	Fix x86_64 memchr for large input sizes	Adhemerval Zanella	2016-12-27	1	-0/+6
\| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \|	Current optimized memchr for x86_64 does for input arguments pointers module 64 in range of [49,63] if there is no searchr char in the rest of 64-byte block a pointer addition which might overflow: * sysdeps/x86_64/memchr.S 77 .p2align 4 78 L(unaligned_no_match): 79 add %rcx, %rdx Add (uintptr_t)s % 16 to n in %rdx. 80 sub $16, %rdx 81 jbe L(return_null) This patch fixes by adding a saturated math that sets a maximum pointer value if it overflows (UINTPTR_MAX). Checked on x86_64-linux-gnu and powerpc64-linux-gnu. [BZ# 19387] * sysdeps/x86_64/memchr.S (memchr): Avoid overflow in pointer addition. * string/test-memchr.c (do_test): Remove alignment limitation. (test_main): Add test that trigger BZ# 19387.
