Subject: [added to the 3.18 stable tree] ARC: Override toplevel default -O2 with -O3
Date: Thu, 30 Jul 2015 22:10:18 -0400	[thread overview]
Message-ID: <1438308644-15635-18-git-send-email-sasha.levin@oracle.com> (raw)
In-Reply-To: <1438308644-15635-1-git-send-email-sasha.levin@oracle.com>

From: Vineet Gupta <vgupta@synopsys.com>

This patch has been added to the 3.18 stable tree. If you have any
objections, please let us know.

===============

[ Upstream commit 97709069214eb75312c14946803b9da4d3814203 ]

ARC kernels have historically been built with -O3, despite top level
Makefile defaulting to -O2. This was facilitated by implicitly ordering
of arch makefile include AFTER top level assigned -O2.

An upstream fix to top level a1c48bb160f ("Makefile: Fix unrecognized
cross-compiler command line options") changed the ordering, making ARC
-O3 defunct.

Fix that by NOT relying on any ordering whatsoever and use the proper
arch override facility now present in kbuild (ARCH_*FLAGS)

Depends-on: ("kbuild: Allow arch Makefiles to override {cpp,ld,c}flags")
