From f465b21b06a17e26c1af7d75603afc481ebce0f6 Mon Sep 17 00:00:00 2001 From: Stefan Liebler Date: Thu, 18 Aug 2022 09:10:48 +0200 Subject: S390: Fix werror=unused-variable in ifunc-impl-list.c. MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit If the architecture level set is high enough, no IFUNCs are used at all and the variable i would be unused. Then the build fails with: ../sysdeps/s390/multiarch/ifunc-impl-list.c: In function ‘__libc_ifunc_impl_list’: ../sysdeps/s390/multiarch/ifunc-impl-list.c:76:10: error: unused variable ‘i’ [-Werror=unused-variable] 76 | size_t i = max; | ^ cc1: all warnings being treated as errors --- sysdeps/s390/multiarch/ifunc-impl-list.c | 4 +++- 1 file changed, 3 insertions(+), 1 deletion(-) (limited to 'sysdeps/s390') diff --git a/sysdeps/s390/multiarch/ifunc-impl-list.c b/sysdeps/s390/multiarch/ifunc-impl-list.c index 5d0c730..7bee543 100644 --- a/sysdeps/s390/multiarch/ifunc-impl-list.c +++ b/sysdeps/s390/multiarch/ifunc-impl-list.c @@ -73,7 +73,9 @@ size_t __libc_ifunc_impl_list (const char *name, struct libc_ifunc_impl *array, size_t max) { - size_t i = max; + /* If the architecture level set is high enough, no IFUNCs are used at all + and the variable i would be unused. */ + size_t i __attribute__ ((unused)) = max; /* Get hardware information. */ unsigned long int dl_hwcap = GLRO (dl_hwcap); -- cgit v1.1
