--- Comment #14 from Richard Biener <rguenth at gcc dot gnu.org> ---
Fixed on trunk which now takes 1.4s on my machine. There is the reported
'alias stmt walking' costs which is somewhat expected.
tree FRE : 0.02 ( 1%) 0.00 ( 0%) 0.04 ( 2%)
1126k ( 3%)
`- alias stmt walking : 0.52 ( 34%) 0.03 ( 18%) 0.52 ( 30%)
248k ( 1%)
tree PRE : 0.02 ( 1%) 0.00 ( 0%) 0.02 ( 1%)
751k ( 2%)
`- alias stmt walking : 0.17 ( 11%) 0.00 ( 0%) 0.17 ( 10%)
75k ( 0%)
I don't think it's necessary to backport this unless we get to see a testcase
that doesn't require turning off so many passes.
