Could you please specify which version of LLVM this is for, the full compiler invocation and the compiler version you are using? Without that, it is impossible to say if it is an issue with your build environment or an issue in LLVM

commit bebc969 (HEAD -> main, origin/main, origin/HEAD)
Author: David Green [email protected]
Date: Mon Sep 26 09:55:10 2022 +0100

[AArch64] Enable FeatureFuseAdrpAdd for all Arm cpus

The commit D120104 enabled FeatureFuseAdrpAdd for -mcpu=generic,
allowing the linker to relax adrp;add pairs where possible. D132075
extended that to neoverse-n1, this patch extends it to all other cortex
and neoverse cpus for the same reasons.

Hello, thank you for your reply.
For the official git repo, I did not change any code.

It looks like you are using manual build commands. Please make sure to use the same flags as if configured by cmake when building.

clang++ -g -O2 -fno-omit-frame-pointer -std=c++11 $f -c &

This doesn't look correct, latest LLVM requires C++17 to build: https://llvm.org/docs/CodingStandards.html#c-standard-versions
