Caveat empptor: I have no access to arm64 hardware nor SPEC code. I would be surprised if -fall-intrinsics is the issue or related to the issue. This option is only relevant if one of the -std= options is used (e.g., -std=f2018). The options, I suspect you need to be concerned about, are -fallow-argument-mismatch and -DSPEC_LP64.
