Gcj 3.0 on Itanium, again

[Boehm, Hans]

I tried a recent (5/15?) gcj 3.0 on an Itanium processor.  I ran into two
problems at the hello.java level of testing:

1) gcj --main=hello hello.java dies with an ICE at dwarf2out.c:4652.  This
goes away with -O (as expected, I guess).  This sounds familiar.  Is it
still expected?

2) No executables actually run, since the boehm-gc/headers.c file is
miscompiled, apparently due to a somewhat known scheduler bug.  I filed it
as PR 2844.  (I'm told this can be worked around with -fno-schedule-insns2,
though I didn't yet try that.)
