------- Comment #3 from mexas at bristol dot ac dot uk  2009-08-11 11:14 -------
Some very basic analysis.
gcc43 builds on alpha, but not on ia64,
so I was trying to spot the difference.

# pwd
/usr/ports/lang/gcc43
# grep -C3 crtfastmath ./work/build/gcc/Makefile

# List of extra object files that should be compiled for this target machine.
# The rules for compiling them should be in the t-* file for the machine.
EXTRA_PARTS = crtbegin.o crtend.o crtbeginS.o crtendS.o crtfastmath.o

so I had a search for t-* files on alpha and ia64, and it seems
some t-* files are missing from ia64:

#################
on alpha
#################

# uname -srm
FreeBSD 6.4-STABLE alpha
# pwd
/usr/ports/lang/gcc43
# find . -name "t-crt*"|grep alpha
./work/gcc-4.3-20090726/gcc/config/alpha/t-crtfm
./work/gcc-4.3-20090726/libgcc/config/alpha/t-crtfm
# 

#################
on ia64
#################

# uname -srm
FreeBSD 8.0-BETA2 ia64
# pwd
/usr/ports/lang/gcc43
# find . -name "t-crt*" | grep ia64
#

so I copied the above 2 t-crtfm files from alpha to ia64
config directory and substituted "alpha" for "ia64":

# cat ./work/gcc-4.3-20090726/gcc/config/ia64/t-crtfm
EXTRA_PARTS += crtfastmath.o

$(T)crtfastmath.o: $(srcdir)/config/ia64/crtfastmath.c $(GCC_PASSES)
        $(GCC_FOR_TARGET) $(LIBGCC2_CFLAGS) -frandom-seed=gcc-crtfastmath -c \
                -o $(T)crtfastmath.o $(srcdir)/config/ia64/crtfastmath.c

# cat ./work/gcc-4.3-20090726/libgcc/config/ia64/t-crtfm
# FIXME drow/20061228 - I have preserved this -frandom-seed option
# while migrating this rule from the GCC directory, but I do not
# know why it is necessary if no other crt file uses it.
crtfastmath.o: $(gcc_srcdir)/config/ia64/crtfastmath.c
        $(gcc_compile) -frandom-seed=gcc-crtfastmath -c \
                $(gcc_srcdir)/config/ia64/crtfastmath.c
#

But the error is still there.

------- Comment #4 from sje at cup dot hp dot com  2009-08-26 22:58 -------
In addition to copying the t-* files over, you also need to modify config.gcc.

If you look at the 'alpha*-*-freebsd*' entry in that file you will see where
tmake_file is set to a list of files including t-crtfm.  The 'ia46*-*-freebsd*'
entry needs the same thing.

------- Comment #7 from sje at cup dot hp dot com  2009-11-16 18:14 -------
The patch worked for me after changing some leading spaces to tabs  If you
grabbed it with a cut-n-paste the patch may have had spaces in it instead of
tabs (or perhaps it was put in the report that way).  You can either change the
spaces to tabs by hand and use patch or you could just apply the patch by hand,
there is only one instance of ia64*freebsd in the libgcc/config.host file and
all you need to do is add the two new lines to the file at that location.

Does freebsd use glibc?  Does freebsd have a system libunwind?  I am going to
guess yes to the first question and no to the second in which case you need to
edit gcc/config.gcc and modify the 'ia64*-*-freebsd*' entry to include the
t-libunwind-elf and ia64/t-glibc-libunwind makefile fragments to the tm_file
list.  That is what 'ia64*-*-linux* does when 'with_system_libunwind' is set to
no.

FreeBSD does not use glibc; never has and never will.
FreeBSD does not have a libunwind.

I think you will need to create a fde-freebsd.c file in gcc/config/ia64 to
define Unwind_FindTableEntry.  See fde-glibc.c and fde-vms.c for examples.

can I add a FBSD ia64 developer email to the CC list (xcllnt@mac.com)?
I tried to do this before, but was refused.

I'm just reporting the bug. I've neigher skill not time
to deal with this.

Sure. sje@ doesn't quite know what he's talking about
because he doesn't know FreeBSD.

See also below.

_Unwind_FindTableEntry is defined in libc.

------- Comment #16 from mexas at bristol dot ac dot uk  2009-12-17 23:00 -------
I just checked that gcc4.2.5 installs fine on ia64 FreeBSD 9.0 current, but
all newer versions fail to build. Is it possible/feasible to debug this
by comparing gcc42 and gcc43? Unfortunately it's beyond my skills, but
I'll be happy to try any patch or something.

After making the change to libgcc/config.host that is also described in
comment #5 I get the same.

libc indeed does feature  _Unwind_FindTableEntry() as I can easily verify
with the following program:

  void _Unwind_FindTableEntry();
  int main() { _Unwind_FindTableEntry(); }

Just, why do we then get this link failure?  Adding -v I see that 
/lib/libc.so.7 is explicitly part of the collect2 invocation.

Because _Unwind_FindTableEntry is marked hidden.
