Bug ID: 45781
Summary: assembler doesn't accept label arithmetic in immediate
Product: libraries
Version: trunk
Hardware: All
OS: All
Status: NEW
Severity: normal
Priority: P
Component: Backend: AArch64
Assignee: unassignedb...@nondot.org
Reporter: rol...@hack.frob.com
CC: arnaud.degrandmai...@arm.com,
llvm-bugs@lists.llvm.org, smithp...@googlemail.com,
ties.st...@arm.com
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.
