[xmlvm-users] Rotate Right

[Troy G. <tro...@gm...>]

>From what I can tell, it looks like the objective C instruction might not
always be the same when doing a shift right.  I posted the following Java
code and corresponding Objective C code to illustrate this.  In Java the
value ends up positive and Objective C negative.  I'm not sure if the left
shift has this same issue.

Thanks again!

   int k2 = -2147483648;

k2 = k2 >>> 1;

assertEquals(1073741824, k2); //this passes


//objective c generated code

   int _r34.i = -2147483648;

_r34.i = _r34.i >> (0x1f & 1);

   STAssertEquals(1073741824, _r34.i, @"Should be 1073741824 and not
-1073741824");
