In term of ports, yes I am agree. As the preformance even with last
Paolo's patches (some changes could be applied to the mainline too,
so it is not only about df), the branch compiler is still 8.7% slower
for SPECint2000 compilation on 2.66Ghz Core2 with
--enable-check=release.
Just to straighten things, only one patch (the one approved by Roger
for mainline) has been applied to dataflow branch.
Of the four patches I posted, the CSE patch could also go into mainline.
The combine patches (not yet applied to dataflow-branch even) give ~1%
in addition to that and Kenny has a patch to provide LUIDs for free to
all passes; that will probably give another 0.5-1%.
Paolo, you did a really great job!
As for posted number, sorry I should be more clear. I posted numbers
for all your 4 patches which I applied manualy to the branch. And
comparison is done with the mainline on the last merge done by Danny.
