Subject: [PATCH 4.19 04/22] crypto: x86/crc32c - fix building with clang ias
Date: Fri, 22 Jan 2021 15:12:22 +0100 [thread overview]
Message-ID: <20210122135732.098221677@linuxfoundation.org> (raw)
In-Reply-To: <20210122135731.921636245@linuxfoundation.org>
From: Arnd Bergmann <arnd@arndb.de>
commit 44623b2818f4a442726639572f44fd9b6d0ef68c upstream.
The clang integrated assembler complains about movzxw:
arch/x86/crypto/crc32c-pcl-intel-asm_64.S:173:2: error: invalid instruction mnemonic 'movzxw'
It seems that movzwq is the mnemonic that it expects instead,
and this is what objdump prints when disassembling the file.
Fixes: 6a8ce1ef3940 ("crypto: crc32c - Optimize CRC32C calculation with PCLMULQDQ instruction")
