There are failures on the libjava testsuites for sh4-unknown-linux-gnu

and it looks that the same failures have been seen for {alpha, hppa,
ia64, powerpc, s390}*-*-linux-gnu in gcc-testresults, though there is
no such failure in the testresults on {i686, x86_64}-*-linux-gnu and
powerpc-apple-darwin*. A typical error is:
Exception in thread "main" java.lang.NoClassDefFoundError: two
at InvokeInterface.class$ (Throwable.java:37)
at InvokeInterface.main (InvokeInterface.java:42)
on sh4-unknown-linux-gnu.

------- Additional Comments From pinskia at gcc dot gnu dot org 2005-05-24 18:15 -------
Confirmed, here is some analysis from RTH on IRC:
[16:54] < rth> we hashed a plt entry.
[16:54] < rth> grrr.
[17:30] < tromey> ah
[17:30] < tromey> I'm glad you debugged this then
[17:32] < rth> so the problem is that we're not marking some methods as local, which means the
make_local_function_alias trick fails.
[17:35] < tromey> in make_local_function_alias I see:
[17:35] < tromey> if (DECL_EXTERNAL (method))
[17:35] < tromey> return method;
[17:35] < tromey> the problem here is that all CNI native methods will be DECL_EXTERNAL, I think
[17:35] < tromey> is this even fixable? (I have no idea about this code either)
[17:35] < rth> oh, is forName a cni method?
[17:36] < tromey> there are 2 overloads, one is native
[17:36] < tromey> oh, wait, both are native
[17:36] < tromey> I didn't realize that
[17:37] < rth> it's very tricky.
[17:37] < tromey> ok
[17:37] < rth> we would have to create hidden aliases for all native methods, and Just Know to use that
alias when building the class table.
[17:38] < rth> so i guess it's not that tricky. just a bit o coordination between c++ and java front ends.
[17:38] < tromey> oh, I see... modify g++ to also emit the hidden aliases
[17:38] < rth> It does assume that cni methods are linked together with its java class.
[17:38] < rth> yes.
[17:39] < tromey> at the moment there is no other way to really use cni methods
[17:39] < tromey> so that is fine, I think
[17:40] < rth> i'll see what i can come up with.
[17:40] < tromey> thank you
And this is reason why it works just fine on ppc-darwin, because darwin always use the function
address and not a stub/plt entry for the function pointers.

Richard's change didn't fix the failures on the PA. I think we need
our own version of UNWRAP_FUNCTION_DESCRIPTOR as function pointers don't
always point to a function descriptor in the 32-bit runtime.
