xscale arm build bootstrap fails

[jeroen dobbelaere <jeroen dot dobbelaere at acunia dot com>]

For some time now, my 'daily' cvs-head bootstraps fails on armv5l-unknown-linux-gnu with :

Configure is done with :

../gcc/configure --with-cpu=xscale --enable-languages=c,c++,f77,objc


For some reason, the gcc/config/arm.md part :

(define_insn "*arm_extendsfdf2"
  [(set (match_operand:DF                  0 "s_register_operand" "=f")
	(float_extend:DF (match_operand:SF 1 "s_register_operand"  "f")))]
  "TARGET_ARM && TARGET_HARD_FLOAT"
  "mvf%?d\\t%0, %1"
  [(set_attr "type" "ffarith")
   (set_attr "predicable" "yes")]
)


seems to be ignored....

any suggestions ?
