Hi everyone, This patch series implements all the BPF CO-RE builtins. It improves the support for __builtin_preserve_access_index and __builtin_preserve_field_info, but also introduces the support for __builtin_btf_type_id, __builtin_btf_preserve_type_info and __builtin_preserve_enum_value.
Regtested in host x86_64-linux-gnu and target bpf-unknown-none. Looking forward to your comments. Best regards, Cupertino
