-Hi!
-
-PR25600 change introduced an optimization of (neg (lt x 0)) to
-(ashirtrt x C), but it is not checking whether x's mode is suitable
-for it.  As it checks that op1 is const0_rtx, I believe MODE_FLOAT
-or VECTOR_MODE_P modes are not a problem, CC modes can certainly appear
-in LT's first operand with second operand const0_rtx.
-So, when we optimize
-(neg:DI (lt:DI (reg:CC ...) (const_int 0)))
-we create something like
-(sign_extend:DI (ashirtrt:CC (reg:CC ...) (const_int 31)))
-which is IMHO invalid RTL, ashirtrt is documented on fixed point modes
-only (guess vector modes aren't listed just by omission) and so is
-sign_extend.
-
-Ok for 4.2/trunk?

-	PR rtl-optimization/33148
-	* simplify-rtx.c (simplify_unary_operation_1): Only optimize
-	(neg (lt X 0)) if X has scalar int mode.
-
-	* gcc.c-torture/compile/20070827-1.c: New test.
