Hi @davemgreen, I am seeing flang/clang failures in the llvm-test-suite after this patch with tests involving copy sign:
- clang failure: https://lab.llvm.org/buildbot/#/builders/183/builds/15854
- flang failure: https://lab.llvm.org/buildbot/#/builders/197/builds/9424 (For instance the SIGN intrinsic is failing in this test: https://github.com/llvm/llvm-test-suite/blob/main/Fortran/gfortran/torture/execute/intrinsic_sign.f90)

Can you check if this is related to your patch that involves copy sign on aarch64?
