From 609054152fd77c9b572bb04c4af2f8da1ed0c86e Mon Sep 17 00:00:00 2001 From: Joseph Myers Date: Fri, 17 Feb 2023 17:23:50 +0000 Subject: Fix ifunc-impl-list.c build for s390 Builds for s390 recently started failing with: ../sysdeps/s390/multiarch/ifunc-impl-list.c: In function '__libc_ifunc_impl_list': ../sysdeps/s390/multiarch/ifunc-impl-list.c:83:21: error: unused variable 'dl_hwcap' [-Werror=unused-variable] 83 | unsigned long int dl_hwcap = features->hwcap; | ^~~~~~~~ https://sourceware.org/pipermail/libc-testresults/2023q1/010855.html Add __attribute__ ((unused)) as already done for another variable there. Tested with build-many-glibcs.py (compilers and glibcs) for s390x-linux-gnu and s390-linux-gnu. Note: s390x-linux-gnu-O3 started failing with a different error earlier; that problem may still need to be fixed after this fix is in. https://sourceware.org/pipermail/libc-testresults/2023q1/010829.html --- sysdeps/s390/multiarch/ifunc-impl-list.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/sysdeps/s390/multiarch/ifunc-impl-list.c b/sysdeps/s390/multiarch/ifunc-impl-list.c index 1532258af2..faa428f9ab 100644 --- a/sysdeps/s390/multiarch/ifunc-impl-list.c +++ b/sysdeps/s390/multiarch/ifunc-impl-list.c @@ -80,7 +80,7 @@ __libc_ifunc_impl_list (const char *name, struct libc_ifunc_impl *array, /* Get hardware information. */ const struct cpu_features *features = &GLRO(dl_s390_cpu_features); - unsigned long int dl_hwcap = features->hwcap; + unsigned long int dl_hwcap __attribute__ ((unused)) = features->hwcap; const unsigned long long * __attribute__((unused)) stfle_bits = features->stfle_bits; -- cgit 1.4.1
