I am attaching a C example where tree-ssa is slower:
[zhivago2:~/src/testspeed] pinskia% time ~/gcc-tree-ssa/bin/gcc fold-const.i -S
18.640u 1.480s 0:21.38 94.1% 0+0k 0+5io 0pf+0w
[zhivago2:~/src/testspeed] pinskia% time ~/fsf-clean-nocheck/bin/gcc fold-const.i -S
9.060u 0.540s 0:09.93 96.6% 0+0k 0+4io 0pf+0w
