From 0a62291d697f1d2882650f5b9f97d331ad9a505b Mon Sep 17 00:00:00 2001 From: Andrii Nakryiko Date: Tue, 29 Sep 2020 15:06:03 -0700 Subject: libbpf: Compile libbpf under -O2 level by default and catch extra warnings For some reason compiler doesn't complain about uninitialized variable, fixed in previous patch, if libbpf is compiled without -O2 optimization level. So do compile it with -O2 and never let similar issue slip by again. -Wall is added unconditionally, so no need to specify it again.
