I haven't looked into the impl yet, but my API-reaction is: "why is this method allowed to fail? Either something is on the cache, or it's not. It should never fail to answer this question". In that case, I would just return an `optional`, or a pointer to MemoryRegionInfo (if it's a big data structure) https://github.com/llvm/llvm-project/pull/202509 _______________________________________________ lldb-commits mailing list [email protected] https://lists.llvm.org/cgi-bin/mailman/listinfo/lldb-commits
