From d3539dd53bf9e37538fd4d8b89783a11fded119f Mon Sep 17 00:00:00 2001 From: Thomas Petazzoni Date: Sat, 2 Nov 2013 16:39:06 +0100 Subject: arch: pass cpu option instead of tune option on ARM Currently, the ARM Config.in logic specifies values for --with-arch/-march and --with-tune/-mtune, but not for --with-cpu/-mcpu. However, this causes problems on ARMv4, because specifying --with-arch=armv4t isn't enough to make gcc generate ARMv4 code: one should also pass --with-cpu=. Moreover, since Buildroot is generally designed to generate code specifically for the configured target, it makes sense to give our own --with-cpu/-mcpu value instead of relying on the default value used by gcc, and only do small optimizations with -mtune.
