Thanks for filing a bug report! Please fill out the TODOs below.

Steps to Reproduce

# build on aarch64 centos 7.9
yum install -y epel-release centos-release-scl
yum install -y git make llvm-toolset-7 devtoolset-7
source /opt/rh/devtoolset-7/enable
export LIBCLANG_PATH=/opt/rh/llvm-toolset-7.0/root/lib64/

@bxq2011hust thanks for the report! Can you show the output of cc --version and as --version?

I suspect that really old versions of GNU as may not support referring to the fp and lr registers as fp and lr -- see e.g. the patch in Comment 8 on this WebKit bug: https://bugs.webkit.org/show_bug.cgi?id=175512

If so, we could modify our assembly to always spell these as x29 and x30 respectively, though that's a bit unfortunate... cc @akirilov-arm , thoughts on this re: aarch64 toolchain requirements/expectations?

Thanks very much. I compare ubuntu 20.04 and CentOS7 and found that ubuntu 20.04 use gcc9. I tried gcc9 on aarch64 CentOS7, now it works fine.

akirilov-arm commented on issue #4226:

I think it is reasonable to support older toolchain versions, provided that it is not too much of a hassle, which seems to be the case here. Personally, I think I have found myself wondering what register numbers fp and lr correspond to more often than the other way round, so I'd say that the proposed fix wouldn't even necessarily diminish readability.

I will incorparate the fix in PR #4195, since I am tinkering with the fiber code anyway.
