[Qemu-devel] [Bug 1834399] [NEW] AArch64: branch out of range

[Kai]

Public bug reported:

I build lib32-qemu which is a multilib variant for mips o32 on project
Yocto with qemumips64. It finally runs command and fails:

The gcc version is 9.1. I have verified that gcc 8.3 works. And there is no 
error when remove option '-Og' with gcc 9.1.

I am not sure whether it is a defect of gcc 9.1 or capstone. Should it
be fixed in capstone? Thanks.
