Subject: [PATCH iproute2-next] Makefile: pass -pipe to the compiler
Date: Tue, 11 Jun 2019 20:05:13 +0200 [thread overview]
Message-ID: <20190611180513.30772-1-mcroce@redhat.com> (raw)
Pass the -pipe option to GCC, to use pipes instead of temp files.
On a slow AMD G-T40E CPU we get a non negligible 6% improvement
in build time.
