From patchwork Fri Dec 23 12:25:42 2011 Content-Type: text/plain; charset="utf-8" MIME-Version: 1.0 Content-Transfer-Encoding: 7bit Subject: Change -mno-thumb to -marm Date: Fri, 23 Dec 2011 12:25:42 -0000 From: Ken Werner X-Patchwork-Id: 17545 Message-Id: <1324643142-29474-2-git-send-email-ken.werner@linaro.org> To: openembedded-core@lists.openembedded.org Recent versions of the GCC reject the -mno-thumb option. In order to prevent the compiler from generating code for the Thumb instruction set the -marm switch should be used instead. For details see GNU bug #47930.
