Looking forward to the upcoming btf_tag > patches! Great! Thanks. I already have a rough pahole patch. Will do a little bit more testing and add flags control and then will send out. > > - Arnaldo > >> [1] https://reviews.llvm.org/D106621 >> [2] https://lore.kernel.org/bpf/20210914223015.245546-1-yhs@fb.com >> >> Signed-off-by: Yonghong Song <yhs@fb.com> >> --- >> lib/bpf | 2 +- >> 1 file changed, 1 insertion(+), 1 deletion(-) >> >> diff --git a/lib/bpf b/lib/bpf >> index 986962f..980777c 160000 >> --- a/lib/bpf >> +++ b/lib/bpf >> @@ -1 +1 @@ >> -Subproject commit 986962fade5dfa89c2890f3854eb040d2a64ab38 >> +Subproject commit 980777cc16db75d5628a537c892aefc2640bb242 >> -- >> 2.30.2 >

Latest upstream LLVM now supports to emit btf_tag to dwarf ([1]) and the kernel support for btf_tag is also landed ([2]). Sync with latest libbpf which has btf_tag support. Next step will be to implement dwarf -> btf conversion for btf_tag.
