This patch implements BTF types deduplication algorithm. It allows to greatly compress typical output of pahole's DWARF-to-BTF conversion or LLVM's compilation output by detecting and collapsing identical types emitted in isolation per compilation unit. Algorithm also resolves struct/union forward declarations into concrete BTF types representing referenced struct/union. If undesired, this resolution can be disabled through specifying corresponding options. Algorithm itself and its application to Linux kernel's BTF types is described in details at: https://facebookmicrosites.github.io/bpf/blog/2018/11/14/btf-enhancement.html Signed-off-by: Andrii Nakryiko <andriin@fb.com> Signed-off-by: Daniel Borkmann <daniel@iogearbox.net> |
