+x86-64: Don't use temp for argument in a TImode register
+
+Don't use temp for a PARALLEL BLKmode argument of an EXPR_LIST expression
+in a TImode register.  Otherwise, the TImode variable will be put in
+the GPR save area which guarantees only 8-byte alignment.
+    
+	PR target/116621
+	* config/i386/i386.cc (ix86_gimplify_va_arg): Don't use temp for
+	a PARALLEL BLKmode container of an EXPR_LIST expression in a
+	TImode register.
+
+	* gcc.target/i386/pr116621.c: New test.
