I ran the spec2006/17 performance again on top of the ToT.  Here is the number:

| Benchmark          | Performance (+ is better) | Code Size (+ is larger) |
| spec2006/milc      | +6.14%                    | -0.04%                  |
| spec2017/deepsjeng | +1.06%                    | -0.32%                  |
| spec2017/xalancbmk | +0.74%                    | 0%                      |
| spec2006/povray    | +0.14%                    | 0%                      |
| spec2006/h264ref   | +0.02%                    | +0.13%                  |

| spec2017/gcc       | -0.02%                    | 0%                      |
| spec2017/povray    | -0.12%                    | 0%                      |
