+Subject: [PATCH] Fix ARM build with GCC trunk.
+
+sysdeps/unix/sysv/linux/arm/unwind-resume.c and
+sysdeps/unix/sysv/linux/arm/unwind-forcedunwind.c have static
+variables that are written in C code but only read from toplevel asms.
+Current GCC trunk now optimizes away such apparently write-only static
+variables, so causing a build failure.  This patch marks those
+variables with __attribute_used__ to avoid that optimization.
+
+Tested that this fixes the build for ARM.
+
+	* sysdeps/unix/sysv/linux/arm/unwind-forcedunwind.c
+	(libgcc_s_resume): Use __attribute_used__.
+	* sysdeps/unix/sysv/linux/arm/unwind-resume.c (libgcc_s_resume):
+	Likewise.
