Re: [PATCH bpf-next 6/9] tools/bpftool: generalize BPF skeleton support and generate vmlinux.h

2020-06-17 09:18 UTC-0700 ~ Andrii Nakryiko [off-list ref]

Adapt Makefile to support BPF skeleton generation beyond single profiler.bpf.c
case. Also add vmlinux.h generation and switch profiler.bpf.c to use it.

clang-bpf-global-var feature is extended and renamed to clang-bpf-co-re to
check for support of preserve_access_index attribute, which, together with BTF
for global variables, is the minimum requirement for modern BPF programs.
