<pre>clang --target=aarch64-linux on this .s file:
```
.text
.pushsection .other,"a",%progbits
0:.skip 2
1:
.popsection
mov x0, #1b - 0b
```
fails with `error: expected compatible register or logical immediate`
The GNU assembler accepts this input. The LLVM assembler accepts the
equivalent construct for x86.</pre>
