Subject: think-o: ARM register byte ps VS fps?
Date: Wed, 17 Apr 2002 13:06:00 -0000	[thread overview]
Message-ID: <3CBDD5E2.7000904@cygnus.com> (raw)

Hello,

I'm looking at the code:

static int
arm_register_byte (int regnum)
{
   if (regnum < ARM_F0_REGNUM)
     return regnum * INT_REGISTER_RAW_SIZE;
   else if (regnum < ARM_PS_REGNUM)
     return (NUM_GREGS * INT_REGISTER_RAW_SIZE
	    + (regnum - ARM_F0_REGNUM) * FP_REGISTER_RAW_SIZE);
   else
     return (NUM_GREGS * INT_REGISTER_RAW_SIZE
	    + NUM_FREGS * FP_REGISTER_RAW_SIZE
	    + (regnum - ARM_FPS_REGNUM) * STATUS_REGISTER_SIZE);
}

where:

#define ARM_FPS_REGNUM 24	/* floating point status register */
#define ARM_PS_REGNUM 25	/* Contains processor status */

While I suspect it ``works'', would ``(regnum < ARM_FPS_REGNUM)'' be better?

enjoy,
Andrew
