From: Fangrui Song <maskray@sourceware.org> To: glibc-cvs@sourceware.org Subject: [glibc] i386: Replace movzx with movzbl Date: Thu, 4 Aug 2022 21:06:52 +0000 (GMT) [thread overview] Message-ID: <20220804210652.1F0E03858407@sourceware.org> (raw) https://sourceware.org/git/gitweb.cgi?p=glibc.git;h=525ca33a61edd733e8ad8c0456f8f811adc2ccb9 commit 525ca33a61edd733e8ad8c0456f8f811adc2ccb9 Author: Fangrui Song <maskray@google.com> Date: Thu Aug 4 14:06:50 2022 -0700 i386: Replace movzx with movzbl Similar to 6720d36b6623c5e48c070d86acf61198b33e144e for x86-64. Clang cannot assemble movzx in the AT&T dialect mode. Change movzx to movzbl, which follows the AT&T dialect and is used elsewhere in the file.
