This was an aarch64 build. It looks like -arm-add-build-attributes is
from Target/ARM/AsmParser/ARMAsmParser.cpp which is only built for
LLVM_TARGET_ARM but not LLVM_TARGET_AARCH64.
Looking in contrib/llvm/tools/clang/lib/Driver/ToolChains/Clang.cpp I
see the option is only added for:
case llvm::Triple::arm:
case llvm::Triple::armeb:
case llvm::Triple::thumb:
case llvm::Triple::thumbeb:
But not llvm::Triple::aarch64. So where is it coming from?
