From bc2dc4406c463174613047d8b7946e12c8808cda Mon Sep 17 00:00:00 2001 From: Nick Desaulniers Date: Sat, 21 Nov 2020 22:17:01 -0800 Subject: [PATCH] compiler-clang: remove version check for BPF Tracing bpftrace parses the kernel headers and uses Clang under the hood. Remove the version check when __BPF_TRACING__ is defined (as bpftrace does) so that this tool can continue to parse kernel headers, even with older clang sources.
