Connor O'Brien 2573965c5e Add option to generate BTF debug info for bpf programs ... Add "btf" option that generates BTF debug info to support easier map inspection. This is accomplished by passing the "-g" flag to clang when compiling the BPF program. The "-g" option also generates a number of DWARF debug sections which are not necessary for loading BTF information, so strip these to avoid increasing file size unnecessarily. bpfloader currently only supports BTF info for maps, not programs, so we also strip the .BTF.ext section containing program BTF info. Bug: 203823368 Test: libbpf_load_test Test: verify time_in_state.o includes .BTF section iff "btf: true" is set Test: verify time_in_state.o still loads if BTF is enabled Change-Id: Ica25b253bace59d04130b0210350188399889bbe Signed-off-by: Connor O'Brien <connoro@google.com>		2022-01-27 12:00:45 -08:00
