Do you also have revision numbers in those logs?

Unfortunately not, but I can see that rev. 193357 was definitely ok
and rev. 193534 definitely broken.  Maybe rev. 193429 also was still ok,
but I'm not sure on that.  Happens with both -O3 (base flags) and -O3
-funroll-loops -fpeel-loops (peak flags).

In the larger revision range the only suspicious patches are the one
for PR51447 and the gcse reg-pressure work from Bin Cheng.

It seems to be compiling build-disjuncts.c btw.

which is from 197.parser - where the compiler currently is after two hours
(but in schedule_block this time).  So maybe that's an entirely different
issue (no compile-time regression recorded for 197.parser in past logfiles).

Oh, and 1080x seems to be what ulimit -t is for these jobs - thus this are
endless loops.

The last time I built and tested the compiler on IA-64, the C testsuite results
were rather bad, especially at -O3.

I just retried and there are still a bunch of C/C++/Fortran failures at -O3.

Don't you have the tentative patch for PR rtl-opt/55158 in your tree?  It
changes ICEs into timeouts in the testsuite.

At trunk 20121203, most of these are the same as PR55158:

$ grep -c "internal compiler error" gcc/testsuite/gcc/gcc.log.sent
947
$ egrep -c "sched-rgn.c:299[08]" gcc/testsuite/gcc/gcc.log.sent
676
