+	* lib/target-supports.exp (check_effective_target_powerpc_future_ok):
+	New target support.
+
+==================== Branch work253-sha, patch #410 ====================
+
+Add xvrlw support.
+
+This patch adds support for a possible new variant of the vector rotate left
+instruction that might be added to a future PowerPC.  This variant (xvrlw) can
+use any VSX register instead of requiring only Altivec registers.
+
+As a potential test, add other variants of vxvrl<x> enabled with the -mxvrld option.
