testsuite issues

[Dan Kegel]

Hi all!

I've been building and testing gcc crosscompilers lately,
and have come across a couple issues with the libstdc++-v3
testsuite.   All of these happen reliably on all targets
I've tried so far (sh4, ppc405, ppc750).  My build scripts
are available at http://kegel.com/crosstool if you want to
check to see what kind of crack I'm smoking :-)

First, the issues I have fixes for:

1. The recent changes to set LD_LIBRARY_PATH seem to have
broken the ability to test libstdc++-v3 remotely.

2. Not sure when this started, but the testsuite invokes the
wrong compiler, and gets confused trying to find itself.

And the fixes:

http://www.kegel.com/crosstool/crosstool-0.13/gcc-3.3-patches/gcc-3.2.3-g++.exp.patch
http://www.kegel.com/crosstool/crosstool-0.13/gcc-3.3-patches/compat.exp.patch
http://www.kegel.com/crosstool/crosstool-0.13/gcc-3.3-patches/gcc-3.3-libstdc++-v3-dg.exp.patch

I'd appreciate feedback on those patches.  Are they good enough to submit?

Now, the issues I haven't solved yet:

1. http://gcc.gnu.org/bugzilla/show_bug.cgi?id=11610
FAIL: 27_io/filebuf_members.cc execution test
rsh output is filebuf_members.exe.7466: .../gcc-ss-3_3-20030714/libstdc++-v3/testsuite/27_io/filebuf_members.cc:62: void test_01(): Assertion `fb_01.is_open()' failed.
XYZ134ZYX
Aborted

Suggestions welcome...

2. A whole bunch more of the same :-(  I can provide details of
how these are failing if anyone's interested.

FAIL: 27_io/filebuf_virtuals.cc execution test
FAIL: 27_io/ifstream_members.cc execution test
FAIL: 27_io/istream_extractor_other.cc execution test
FAIL: 27_io/istream_seeks.cc execution test
FAIL: 27_io/istream_unformatted.cc execution test
FAIL: 27_io/ostream_inserter_other.cc execution test

I gather these aren't failing on x86 native builds.  Is anyone
else seeing them?

3. The platforms I run the tests on have a very limited amount
of disk space available.  I hear some of the tests create very
large files.  This won't work well... there's probably a maximum
of 4MB of space available for each test to work with.  I imagine
I'll find out if that's a problem soon.

Thanks,
Dan
