glibc: update upstream patches
2017-10-10 16:38:13 +02:00

Subject: [PATCH 37] string/stratcliff.c: Replace int with size_t [BZ
#21982]
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
Fix GCC 7 errors when string/stratcliff.c is compiled with -O3:
stratcliff.c: In function ‘do_test’:
cc1: error: assuming signed overflow does not occur when assuming that (X - c) <= X is always true [-Werror=strict-overflow]
[BZ #21982]
* string/stratcliff.c (do_test): Declare size, nchars, inner,
middle and outer with size_t instead of int. Repleace %d and
%Zd with %zu in printf. Update "MAX (0, nchars - 128)" and
"MAX (outer, nchars - 64)" to support unsigned outer and
nchars. Also exit loop when outer == 0.
(cherry picked from commit 376b40a27a6783ea7f73ae577be320df66aeb36d)
