glibc-2.2.5 regression test results with sh4 and gcc-3.3

[Dan Kegel]

Hi all,
I can build x86->sh4 crosstoolchains with gcc-3.3/glibc-2.2.5 from scratch
without any trouble, and the resulting toolchains pass most of the
gcc regression tests.  However, there is trouble with many glibc tests.
(I know, glibc-2.2.5 is old, and I should be testing glibc-2.3.2.
I will try that again soon; last time I had trouble getting started with it.)

For what it's worth, the patches I'm using are
http://www.kegel.com/crosstool/crosstool-0.14/glibc-2.2.5-patches/
and
http://www.kegel.com/crosstool/crosstool-0.14/gcc-ss-3_3-20030714-patches/
(These are the minimal patches to get gcc/glibc to compile on all
the platforms glibc supports, and to get the test suites to work remotely.)

The trouble breaks down into four basic symptoms; see the summary below.
If you know of patches that address any of these, please let me know.
I've looked briefly at the patches in
http://www.sh-linux.org/rpm-2003/SRPMS/glibc-2.2.5-8.src.rpm
but didn't see anything obviously related.
Thanks!

------------------

One test, test-fpucw, terminates with the message
   control word is 0x80004 but should be 0x80000.

The code for that test is simple:
   _FPU_GETCW (cw);

   cw &= ~_FPU_RESERVED;

   if (cw != (_FPU_DEFAULT & ~_FPU_RESERVED))
     printf ("control word is 0x%lx but should be 0x%lx.\n",
             (long int) cw, (long int) (_FPU_DEFAULT & ~_FPU_RESERVED));

------------------

The following tests fail with:
   Floating point exception
   Error 136

test-fenv
test-misc
test-float
test-double
test-ifloat
test-idouble

------------------

The following tests fail with:
   Didn't expect signal from child: got `File size limit exceeded'
   Error 1

tst-preadwrite
tst-preadwrite64

(Daniel Jacobowitz posted a patch that may fix pread/pwrite; it's
at http://www.kegel.com/crosstool/crosstool-0.14/glibc-2.3.2-patches/glibc-drow-sh.patch
but I haven't really looked at it, nor have I tried backporting the
pread/pwrite part of the patch to glibc-2.2.5 yet.)

------------------

The following tests fail with errors like:
   Operation failed : Invalid argument
   aio_write: wrong size: 100, should be 1000
   comparison failed for aio_read test
   lio_listio (write): wrong size: 0, should be 1000
   aio_fsync (aio_write): wrong size: 0, should be 1000
   Error 1

tst-aio
tst-aio64
