How about smiLeftShift()?

[srdjan, 2011/12/15 22:27:16]

Once I do changes to the left shift. This CL changes only right shift.

+    int ShiftRight(int a, int b) { return a >> b; }
+    
+    for (int i = 0; i < 2000; i++) {
+      var r = ShiftRight(10, 2);
+      Expect.equals(2, r);
+    }
+    // ShiftRight is optimized.
+    Expect.equals(0, ShiftRight(10, 64));
+    // Deoptimize ShiftRight because 'a' is a Mint.
+    var mint = 1 << 63;
+    Expect.equals(1 << 3, ShiftRight(mint, 60));
+  }
