On the attached testcase with -O1 cc1plus either hangs, or spends enormous
amount of time in:

there was a patch that spark wanted to get in at the end of 4.3 that
changes the order that we traverse blocks, but it had a problem. I
think that we may want to get that patch correct and see if it improves
this.

I'm still building the compiler to reproduce the problem.
But can somebody try compiling with --param df-double-queue-threshold-factor=0
and see if it helps ?

--param df-double-queue-threshold-factor=0 helps, at -O1 with it the testcase
compiled under 45seconds (with standard trunk checking).

------- Comment #9 from steven at gcc dot gnu dot org 2008-11-16 12:17 -------
Advice to folks caring about compiler stability instead of supposedly faster:
Always use double-queue instead of overeager. The overeager solver is just not
reliable enough, and I have never found any proof for the speed benefit that
Seongbae claimed it has.
The theoretical worst-case time for the overeager algorithm is exponential in
the number of basic blocks, for densely connected CFGs. I have argued before
that such an algorithm should *never* have been selected as the default for
GCC, even if it is, say, 0.5% faster for a GCC bootstrap (but I did the
comparison last year and I have never actually measured any benefits of
overeager over double queue).
For the double queue, and also for the hybrid search, the number of passes has
a reasonable proven upper bound for any CFG, so these algorithms are much more
reliable.

------- Comment #10 from spark at gcc dot gnu dot org 2008-11-17 06:13 -------
I agree that the overeager has the worse worst-case bound. I'll happily approve
a patch that drops overeager and leave double-queuing only, provided we have
empirical data over some known programs to show that it is a compile time
neutral change (I bet it will be so, or worst case, only a very slight
slowdown).

Created an attachment (id=16842)
--> (http://gcc.gnu.org/bugzilla/attachment.cgi?id=16842&action=view)
Remove overeager solver
Bootstrapped and tested on ia64-unknown-linux-gnu.
Time-tested by compiling cc1-i/cc1plus-i files for ia64, CSiBE, and various
test cases for old PRs about slow data flow solving.
