RE: [Linux-ia64] gcc 3.0.2 questions

["Boehm, Hans" <hans_boehm@hp.com>]

How did you configure the compiler?  I believe fastjar is needed only for
Java.

I wouldn't recommend using the 3.0.2 compiler for Java on Itanium.  I
haven't tried it, but I believe it has serious problems with generating
object layout information for the garbage collector.  3.0 and 3.0.1 are
probably more functional.

If you want the Java compiler, your best bet at this stage is probably the
3.1 cvs tree and asking me for some patches.  But I haven't built an IA32 to
IA64 cross-compiler in a long time.
