Bug ID: 39228
Summary: error("misaligned ldr/str offset") on aarch64-windows
build
Product: lld
Version: unspecified
Hardware: PC
OS: Windows NT
Status: NEW
Severity: enhancement
Priority: P

We're hitting a case where `Size` is 8 but `Imm` ends with hex digit 4 at
https://github.com/llvm-mirror/lld/blob/1b68a4c56aee3d9008dd08e8bbc49e314a12b592/COFF/Chunks.cpp#L247
This happens with cl.exe as the compiler, as we can't yet build with clang-cl
due to missing support of https://reviews.llvm.org/D51204. Under link.exe these
files link without any errors. I'm assuming that means that lld-link ought to
handle it too.
Hopefully the attached zip file has enough state to reproduce this, but let me
know if I've missed something.
