Bug ID: 31080
Summary: xacquire/xrelease parsed improperly
Product: libraries
Version: 3.9
Hardware: PC
OS: All
Status: NEW
Severity: normal
Priority: P
Component: Backend: X86
Assignee: [email protected]

```
$ llvm-mc
xrelease lock subq $1,4(%rip)
.text
<stdin>:1:15: error: unexpected token in argument list
xrelease lock subq $1,4(%rip)
^
```
gcc accepts this fine. For now treating is as a separate instruction with `;`
works,
but seems a little wrong.
```
xrelease; lock subq $1,4(%rip)
```
