From: Zeng Heng Date: Tue, 15 Aug 2023 04:09:15 +0000 (+0800) Subject: kselftest/arm64: add jscvt feature to hwcap test X-Git-Tag: v6.6-rc1~184^2^2~1 X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=fcb0b51a5dca1f69f408dfe5fd970cf167d41538;p=thirdparty%2Flinux.git kselftest/arm64: add jscvt feature to hwcap test Add the jscvt feature check in the set of hwcap tests. Due to the requirement of jscvt feature, a compiler configuration of v8.3 or above is needed to support assembly. Therefore, hand encode is used here instead.
