I've tested on two systems with -O3 -fomit-frame-pointer:

* 1.2 GHz UltraSPARC-T2:

real        1:34.16
user        1:33.32
sys            0.43

 phase opt and generate  :  93.17 (99%) usr   0.40 (95%) sys  93.58 (99%) wall 
 31673 kB (93%) ggc

 alias stmt walking      :  30.76 (33%) usr   0.03 ( 7%) sys  30.84 (33%) wall 
    25 kB ( 0%) ggc

* 1.35 GHz UltraSPARC-IV:

real          49.37
user          44.41
sys            0.47

 phase opt and generate  :  44.40 (99%) usr   0.33 (97%) sys  47.62 (99%) wall 
 31673 kB (93%) ggc

 alias stmt walking      :  12.93 (29%) usr   0.02 ( 6%) sys  13.05 (27%) wall 
    25 kB ( 0%) ggc
