The easiest way to make this go away, is to make TImode not a workable mode on
mips64.

I think TImode has to be a workable mode for IRIX 6.  Long double is TFmode,
and it would certainly seem odd to support TImode and not TFmode.  (I seem to
remember the s390 folks having to add TImode support exactly because they had
TFmode support.

How hard is it to add the TI mode functions? Is it specific to IRIX, or does it
happen (as I believe) on mips-linux as well? And are the maintainers ready to
do it?

I'm adding mips maintainers in the Cc list.

Subject: RE:  [4.1/4.2 regression] libgfortran unresolvable symbols on irix6.5

Just tried to check this on an irix6.5.22m Origin 300

Bootstrap fails in stage 2 with repeated messages:
/disk4/billingd/src/gcc/gcc/toplev.h:183: undefined reference to `__ctzdi2'

I am building with
  ${SRCDIR}/configure \
    --enable-shared \
    --enable-haifa \
    --enable-threads=single \
    --disable-libjava \
    --with-as=/disk4/billingd/tmp/binutils-2.16.1/bin/as \
    --with-ld=/disk4/billingd/tmp/binutils-2.16.1/bin/ld \
    --disable-nls \
    --with-gmp=/usr/local \
    --enable-languages=c \
    --prefix=${PREFIX}
  make bootstrap

Any ideas?

[Bug target/22209] [4.1 regression] libgfortran unresolvable symbols on irix6.5

[roger at eyesopen dot com]

------- Comment #10 from roger at eyesopen dot com  2006-02-09 14:41 -------
Hi David, nm $objdir/gcc/libgcc.a contains both __ctzdi2 and __ctzti2 for me.

grasp% nm libgcc.a | grep ctz
_ctzsi2.o:
00000000 T __ctzdi2
_ctzdi2.o:
00000000 T __ctzti2

The post-commit bootstrap and regression test on IRIX 6.5.19m just completed
fine for me, with the following gfortran test results.

gfortran
# of expected passes            11485
# of unexpected failures        20
# of expected failures          12
# of unsupported tests          26

Could you investigate this failure a bit further?  I've no idea why you should
be seeing these problems.  If it makes any difference I configure with:

${SRCDIR}/configure --with-gnu-as --with-as=/usr/local/bin/as \
                    --with-gnu-ld --with-ld=/usr/local/bin/ld

Where the above as and ld are both binutils 2.16.  I've had trouble with
binutils 2.16.1's ld on IRIX built both with MIPSPro cc and gcc 3.4.3 so we
currently stick with 2.16, but I'll investigate if that makes a difference.

------- Comment #11 from roger at eyesopen dot com  2006-02-09 14:54 -------
p.s. I can also confirm that this patch fixes the test case in PR25028 for me
on mips-sgi-irix6.5.  This failed previously with undefined references to
__floattisf and __floattidf, but now not only compiles and links but produces
the correct output.

Many thanks to Mark, Richard and David!  This is now fixed on both mainline and
the gcc-4_1-branch in time for the 4.1 release.  On mips-sgi-irix6.5, for the
4.1 branch I now see the following (which is much better than before!)
