From d354bfde174514973309e788e11c286f1667c2f5 Mon Sep 17 00:00:00 2001 From: Alexey Brodkin Date: Thu, 19 May 2016 08:20:33 +0300 Subject: toolchain: Bump ARC tools to arc-2016.03 This change switches ARC tools to the most recent arc-2016.03 version. ARC GNU tools of version arc-2016.03 bring some quite significant changes like: * Binutils v2.26+ (upstream commit id 202ac19 with additional ARC * patches) * GCC v4.8.5 * GDB 7.10 More about changes, improvements and fixes could be found here: https://github.com/foss-for-synopsys-dwc-arc-processors/toolchain/releases/tag/arc-2016.03 Signed-off-by: Alexey Brodkin --- .../001-revert_register_mode_search.patch | 65 ------ .../patches/arc-2015.06/002-weak_data_fix.patch | 42 ---- .../arc-2015.06/003-universal_initializer.patch | 94 -------- .../patches/arc-2015.06/004-case_insensitive.patch | 14 -- .../patches/arc-2015.06/010-documentation.patch | 23 -- .../patches/arc-2015.06/020-no-plt-backport.patch | 28 --- .../gcc/patches/arc-2015.06/100-uclibc-conf.patch | 33 --- .../210-disable_libsanitizer_off_t_check.patch | 11 -
