Fails after PRE.

Reduced testcase requiring just a jc1 executable (assuming gcc is built in a
subdirectory of the toplevel, i.e. ../configure):

Interesting, can you try the command-line I posted on both ppc and
i386, plus -fdump-tree-all-details, and see what the differences are
in the tree dumps?

Thanks!

> can you try the command-line I posted

I guess it is from comment #6. Using a stupid copy and paste, I get

RefTemplate: Undefined variable.

After some trial and error, I ran

/opt/gcc/gcc4.5w/libexec/gcc/i686-apple-darwin9/4.5.0/jc1
/opt/gcc/_gcc_clean/libjava/classpath/lib/gnu/CORBA/Poa/gnuPOA.class

-findirect-dispatch -fno-indirect-classes -fno-common
-fbootclasspath=/opt/gcc/_gcc_clean/libjava/classpath/lib/
-fdump-tree-all-details

and the same variant on ppc, and got no errors but a bunch of files in
/opt/gcc/_gcc_clean/libjava/classpath/lib/gnu/CORBA/Poa/
I have moved them to another directory, but don't know what to do with them .

On Intel jc1 comes from revision 146795. For my last bootstrap I have only
(successfully) build c, c++, and fortran, so if I need a matching jc1, I'll
have to do a full (failing) bootstrap and won't have anything before tomorrow
morning.

Note, I really don't know anything about Java except the name.

-mtune=generic should be eliminated from the ppc build, too (but intel
fails also without it)

This is precisely why I have tried the test without -m64.

[Bug java/39940] [4.5 Regression] Bootstrap failure in libjava on i686-apple-darwin9

[rguenth at gcc dot gnu dot org]

------- Comment #18 from rguenth at gcc dot gnu dot org  2009-05-01 19:54 -------
Hm, with a cross configured like

configure --disable-nls --enable-languages=java --target=i686-apple-darwin9

and make all-gcc I just get

gcc$ ./jc1 -quiet
~/src/trunk/libjava/classpath/lib/gnu/CORBA/Poa/gnuPOA\$RefTemplate.class
-fhash-synchronization -fuse-divide-subroutine -fcheck-references

-findirect-dispatch -fno-indirect-classes -fno-common
-fbootclasspath=~/src/trunk/libjava/classpath/lib 
Segmentation fault

:/

So I still cannot reproduce this.  The segfault happens because the FE
endlessly recurses in

#295 0x080ddae8 in layout_class_methods (this_class=0xb7761a8c)
    at /home/richard/src/trunk/gcc/java/class.c:2559

Also reproducible with compiler to powerpc-apple-darwin, same error message.

But jc1 builds if you just "make jc1", and it exhibits the same bug.

The difference between ppc and intel, is that for the former it does not break
bootstrap. Any idea why?

Now this is funny.  I get the same error even with a cross from i686-darwin to
i686-pc-linux-gnu!
