Hi all, I'd like to report a bug for toolchain related with arm64.
When I work on perf tool and found some kernel symbols are failed to be parsed based on kernel address. This issue can be simplized with the command addr2line: $ aarch64-none-linux-gnu-addr2line -e vmlinux ffff800010e11bb4 :? $ aarch64-none-linux-gnu-addr2line -e vmlinux ffff800010259700 :? I tried two toolchains, one in on X86 and another is on Arm64 native, both have the same result. The toolchain versions are: addr2line on Juno-r2 board: root@debian:~/coresight_test# addr2line -v GNU addr2line (GNU Binutils for Debian) 2.31.1 Copyright (C) 2018 Free Software Foundation, Inc.
