From d0bfbedad72b74f93b028c26474acba1ba3d73ed Mon Sep 17 00:00:00 2001 From: Jiri Olsa Date: Wed, 13 Feb 2019 13:32:37 +0100 Subject: [PATCH] perf tools: Compile perf with libperf-in.o instead of libperf.a There's no need for perf build to use libperf.a, we can use directly libperf-in.o. The libperf.a stays as a target if needed: $ make libperf.a ...
