Linking libstdc++ with gcc-3.0.2 prerelease fails on IA64

Linking libstdc++ with gcc-3.0.2 prerelease fails on IA64

[Krishnakumar B]

Hi,

I am trying to bootstrap IA-64. During the link stage of libstdc++, I get
the following message. I can reproduce the failure at the same stage with
the snapshots 200011001 and 20011007 also.

I see this with the mainline CVS.  Rather than looking into it I've just
avoided building c++ and java.  Unless someone already knows what the
problem is I can look into it.

As I said, the same failure occurs with the CVS mainline.

I believe it is a binutils bug. Please tell me how to reproduce it. I
will make sure it is fixed.

Thanks.

Just try bootstrapping gcc on IA64. Linking libstdc++ fails with this
error. True for both the mainline or prerelease. I resorted to linking
using binutils 2.11.90.0.8 though I am sure that it will link with any
binutils other than 2.11.92.0.5.

Yes, the failure occurs with GNU ld version 2.11.92.0.5 20011005 but not
with GNU ld version 2.11.90.0.8 (with BFD 2.11.90.0.8).  Build C and C++;
it doesn't require a bootstrap.  I get the same failure with a cross
build on i686-unknown-linux-gnu.  Use any recent 3.0 or 3.1 GCC source.

I need the exact steps in order to duplicate the problem.

OK, here's what I did on an IA-64 system; it's pretty basic.
gcc-mainline is a symbolic link to the CVS gcc tree, last updated
Wed Oct 10 19:07:42 UTC 2001.

ld -v:
   GNU ld version 2.11.92.0.5 20011005.
gcc -v (partial):
   gcc version 2.96 20000731 (Red Hat Linux 7.1 2.96-96).
uname -a:
   Linux elm3a81 2.4.7-2smp #1 SMP Tue Aug 14 04:31:14 EDT 2001 ia64 unknown

mkdir gcc-obj
cd gcc-obj
../gcc-mainline/configure --prefix=/home/janis/gnu/tools \
  --enable-languages="c,c++" > configure.log 2>&1
make > make.log 2>&1

I've got two object files that will cause the same failure with the command
"ld -G stl-inst.o string-inst.o -o libx.so", with either a native ia64-linux
linker or a cross linker on i686-pc-linux-gnu (both 2.11.92.0.5).  Let me
know if you'd like those files.
