From 05aca6da3b5ab3c5c6003dbbefc9580d9a6a308b Mon Sep 17 00:00:00 2001 From: Andrii Nakryiko <andriin@fb.com> Date: Fri, 19 Jun 2020 16:17:00 -0700 Subject: tools/bpftool: Generalize BPF skeleton support and generate vmlinux.h 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.
