8 BTF (BPF Type Format) is the metadata format which encodes the debug info
10 types. The BTF was later extended to include function info for defined
11 subroutines, and line info for source/line information.
13 The debug info is used for map pretty print, function signature, etc. The
15 info helps generate source annotated translated byte code, jited code and
23 verifies the BTF info before using it. The ELF file format is a user space
27 debug info (mostly types related) referenced by the bpf program. These two
88 Note that the type section encodes debug info, not just pure types.
