[PATCH] sim: common: Fix pointer sign warnings

[Stafford Horne <shorne@gmail.com>]

When compiling we get the following warnings:

  common/cgen-accfp.c: In function ‘fixsfsi’:
  common/cgen-accfp.c:370:18: warning: pointer targets in passing argument 1 of ‘sim_fpu_to32i’ differ in signedness [-Wpointer-sign]
     sim_fpu_to32i (&res, &op1, sim_fpu_round_near);
                  ^
  common/cgen-accfp.c: In function ‘fixdfsi’:
  common/cgen-accfp.c:381:18: warning: pointer targets in passing argument 1 of ‘sim_fpu_to32i’ differ in signedness [-Wpointer-sign]
     sim_fpu_to32i (&res, &op1, sim_fpu_round_near);
                  ^
sim/common/ChangeLog:

yyyy-mm-dd  Stafford Horne  <shorne@gmail.com>

	* cgen-accfp.c (fixsfsi): Change res from unsigned32 to signed32.
	(fixdfsi): Change res from unsigned32 to signed32.
