From cc1b91eabd806057aa7e3058a84bf129ed36e157 Mon Sep 17 00:00:00 2001 From: Stefan Liebler Date: Tue, 30 Jan 2024 09:34:32 +0100 Subject: [PATCH] S390: Fix building with --disable-mutli-arch [BZ #31196] MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Starting with commits - 7ea510127e2067efa07865158ac92c330c379950 string: Add libc_hidden_proto for strchrnul - 22999b2f0fb62eed1af4095d062bd1272d6afeb1 string: Add libc_hidden_proto for memrchr building glibc on s390x with --disable-multi-arch fails if only the C-variant of strchrnul / memrchr is used. This is the case if gcc uses -march < z13. The build fails with: ../sysdeps/s390/strchrnul-c.c:28:49: error: ‘__strchrnul_c’ undeclared here (not in a function); did you mean ‘__strchrnul’? 28 | __hidden_ver1 (__strchrnul_c, __GI___strchrnul, __strchrnul_c); With --disable-multi-arch, __strchrnul_c is not available as string/strchrnul.c is just included without defining STRCHRNUL and thus we also don't have to create the internal hidden symbol.
