Hi, At this point this series is mostly a draft for Pierrick.
After introducing the generic TargetInfo API [*], we implement the ARM variants, then use the API to remove target-specific code, allowing to eventually remove the target-specific arm_ss[] source set in meson.build, having all objects in arm_common_ss[]. Various header cleanups are necessary before getting there. Regards, Phil.
