[PATCH] Fix PR11674

[Zdenek Dvorak]

Hello,

this bug is caused by this pattern in md:

(define_expand "floatunssisf2"
  [(use (match_operand:SF 0 "register_operand" ""))
   (use (match_operand:SI 1 "register_operand" ""))]
  "TARGET_SSE && TARGET_SSE_MATH && !TARGET_64BIT"
  "x86_emit_floatuns (operands); DONE;")

x86_emit_floatuns only works for DImode.  I am not sure what was the
intent here, but making x86_emit_floatuns to also handle SImode
seems to solve the problem.

Zdenek

	* config/i386/i386.c (x86_emit_floatuns): Also handle SImode
	operand.
