Hi, At this point this series is mostly a draft for Pierrick. It implement his idea of a per-binary structure containing all target-specific information, exposing them via a target-agnostic API. Commits are barely commented, since I'd rather get feedback before pursuing further.
Available here, based on tcg-next: https://gitlab.com/philmd/qemu/-/tags/single-binary-target-info-api-rfc-v1 Another series will follow with the ARM implementation. Regards, Phil.
