------- Comment #1 from g0dsowncountry at yahoo dot com 2008-09-05 20:46 -------
Noticed that if GCC is configured with additional parameters
'--with-arch=5kc --with-tune=5kc', PASS 1 build completes (gcc version 4.4.0
20080904 (experimental)).
mipsisa64-linux-* builds fine w/o these extra configure options.
If this is the intended way to currently configure/build for mipsisa64r2-linux
targets, please confirm, so that this could be marked as invalid..?

I guess this issue can be fixed by following (untested) trivial patch:

Nebu, can you bootstrap and regression test this patch on your target?

Using top-of-stack GCC and Binutils from Nov 17, issue still present; Applied
the below patch and re-tried, no change in behavior. Fails the same way...
FYI, This is what I'm using to configure GCC: -
../gcc-svn-111708/configure --prefix=<> --host=i686-host_pc-linux-gnu
--target=mipsisa64r2-linux --build=i686-host_pc-linux-gnu --disable-nls
--with-newlib --disable-shared --disable-threads --with-gnu-as --with-gnu-ld
--disable-soft-float --enable-symvers=gnu --enable-__cxa_atexit
--disable-libmudflap --disable-libssp --disable-libffi --disable-libgomp
--with-local-prefix=<> --with-sysroot=<> --enable-multilib --enable-languages=c

This one is tested with a cross and works for me:

With the patch in Comment #5, the test case passes; but the GCC Build fails
with the following error message while creating
