2014-06-17  Kugan Vivekanandarajah  <kuganv@linaro.org>

	* config/arm/arm.c (arm_atomic_assign_expand_fenv): call
	default_atomic_assign_expand_fenv for !TARGET_HARD_FLOAT.
	(arm_init_builtins) : Initialize builtins __builtins_arm_set_fpscr and
	__builtins_arm_get_fpscr only when TARGET_HARD_FLOAT.
	* config/arm/vfp.md (set_fpscr): Make pattern conditional on
	TARGET_HARD_FLOAT.
	(get_fpscr) : Likewise.
