* without this patch it does apply --fix-v4bx not only to armv4, but also all higher (because they also have armv4 in TUNE_FEATURES) * it causes SIGILL on armv4t http://lists.linuxtogo.org/pipermail/openembedded-devel/2012-November/042298.html * someone please test on armv4 device (I tested only bitbake -e output that it's correctly applied with DEFAULTTUNE == armv4 * maybe we can should fix this in binutils instead (both 2.22 and 2.23 are affected) (From OE-Core rev: efe03fc00fc051bede69ced6643a8f25d02eabde) Signed-off-by: Martin Jansa <Martin.Jansa@gmail.com> Signed-off-by: Saul Wold <sgw@linux.intel.com> Signed-off-by: Richard Purdie <richard.purdie@linuxfoundation.org>
