Subject: [PATCH] x86-64: Replace movzx with movzbl
|
|
Content-type: text/plain; charset=UTF-8
|
|
|
|
Clang cannot assemble movzx in the AT&T dialect mode.
|
|
|
|
../sysdeps/x86_64/strcmp.S:2232:16: error: invalid operand for instruction
|
|
movzx (%rsi), %ecx
|
|
^~~~
|
|
|
|
Change movzx to movzbl, which follows the AT&T dialect and is used
|
|
elsewhere in the file.
