Subject: toolchain: Bump ARC tools to arc-2016.03
X-Git-Url: http://git.openwrt.org/?p=openwrt%2Fstaging%2Fwigyori.git;a=commitdiff_plain;h=d354bfde174514973309e788e11c286f1667c2f5

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

-	This patch brings over a few features from MirBSD:
-	* -fhonour-copts
-	  If this option is not given, it's warned (depending
-	  on environment variables). This is to catch errors
-	  of misbuilt packages which override CFLAGS themselves.
-	* -Werror-maybe-reset
-	  Has the effect of -Wno-error if GCC_NO_WERROR is
-	  set and not '0', a no-operation otherwise. This is
-	  to be able to use -Werror in "make" but prevent
-	  GNU autoconf generated configure scripts from
-	  freaking out.
-	* Make -fno-strict-aliasing and -fno-delete-null-pointer-checks
-	  the default for -O2/-Os, because they trigger gcc bugs
-	  and can delete code with security implications.
-
-	This patch was authored by Thorsten Glaser <tg at mirbsd.de>
-	with copyright assignment to the FSF in effect.

+	This patch brings over a few features from MirBSD:
+	* -fhonour-copts
+	  If this option is not given, it's warned (depending
+	  on environment variables). This is to catch errors
+	  of misbuilt packages which override CFLAGS themselves.
+	* -Werror-maybe-reset
+	  Has the effect of -Wno-error if GCC_NO_WERROR is
+	  set and not '0', a no-operation otherwise. This is
+	  to be able to use -Werror in "make" but prevent
+	  GNU autoconf generated configure scripts from
+	  freaking out.
+	* Make -fno-strict-aliasing and -fno-delete-null-pointer-checks
+	  the default for -O2/-Os, because they trigger gcc bugs
+	  and can delete code with security implications.
+
+	This patch was authored by Thorsten Glaser <tg at mirbsd.de>
+	with copyright assignment to the FSF in effect.
