Hi,
While testing Anshuman Khandual's branch stack sampling ABI, and BRBE driver ([1] and [2] respectively) I've been using this test to check the consistency between arches (x86 and Arm64).
We might extend it with Arm64-specific tests once the BRBE driver has been reviewed and merged, but for now I think this is generic enough to cover both x86 LBR and Arm BRBE.
Thanks, German
