From: Stefan Liebler Date: Tue, 18 Dec 2018 12:57:03 +0000 (+0100) Subject: S390: Use hwcap instead of dl_hwcap in ifunc-resolvers. X-Git-Tag: glibc-2.29~184 X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=e8023f2685c9f97e72bbe9d2a9c968e0d8438371;p=thirdparty%2Fglibc.git S390: Use hwcap instead of dl_hwcap in ifunc-resolvers. The renaming of hwcap arguments in ifunc-resolvers is needed in order to prepare for further commits which refactors ifunc handling for memset, memcmp, and memcpy. Now you are able to use s390_libc_ifunc_init which stores the stfle bits within the expression for an ifunc-resolver generated by s390_libc_ifunc_expr.
