Subject: [PATCH 36/44] perf feature detection: Add -lopcodes to feature-libbfd
Date: Thu, 21 Mar 2019 15:51:34 -0300	[thread overview]
Message-ID: <20190321185142.11441-37-acme@kernel.org> (raw)
In-Reply-To: <20190321185142.11441-1-acme@kernel.org>

From: Song Liu <songliubraving@fb.com>

Both libbfd and libopcodes are distributed with binutil-dev/devel. When
libbfd is present, it is OK to assume that libopcodes also present. This
has been a safe assumption for bpftool.

This patch adds -lopcodes to perf/Makefile.config. libopcodes will be
used in the next commit for BPF annotation.
