[Bug target/14925] New: libunwind enabled gcc generates incompatible libgcc_s.so.1

[Bug target/14925] New: libunwind enabled gcc generates incompatible libgcc_s.so.1

[hjl at lucon dot org]

When libunwind is installed on the system, the gcc configure
will enable it automatically by default. As the result, the new
libgcc_s.so.1 is very different and not backward compatible with
the previous libgcc_s.so.1. The new libgcc_s.so.1 depends on
libunwind.so. Many symbols used to defined in libgcc_s.so.1 are
now provided by libunwind.so and unversioned. Anything referencing
those symbols won't work now like:

/usr/lib/gcc-lib/ia64-redhat-linux/3.2.3/adalib//libgnat.so: undefined reference
to `_Unwind_GetRegionStart@GCC_3.0'
/usr/lib/gcc-lib/ia64-redhat-linux/3.2.3/adalib//libgnat.so: undefined reference
to `_Unwind_SetGR@GCC_3.0'
/usr/lib/gcc-lib/ia64-redhat-linux/3.2.3/adalib//libgnat.so: undefined reference
to `_Unwind_GetLanguageSpecificData@GCC_3.0'
/usr/lib/gcc-lib/ia64-redhat-linux/3.2.3/adalib//libgnat.so: undefined reference
to `_Unwind_GetIP@GCC_3.0'
/usr/lib/gcc-lib/ia64-redhat-linux/3.2.3/adalib//libgnat.so: undefined reference
to `_Unwind_GetGR@GCC_3.0'
/usr/lib/gcc-lib/ia64-redhat-linux/3.2.3/adalib//libgnat.so: undefined reference
to `_Unwind_SetIP@GCC_3.0' collect2: ld returned 1 exit status

I do not think there is any way around this.  Either use libunwind or not use it, do not build one 
compiler with and then one without or the other way around.

I don't think gcc 3.4.0 should enable libunwind by default before
binary compatibility issue is resolved.

Until someone (Richard Henderson?) says that this is really a defect, I'm not
going to treat it as a showstopper.

There's a backwards compatible fix for 3.4.1 -- have the new libgcc define the
old, versioned symbols even when using libunwind.  Since there's a backwards
compatible fix later, I'm not worried now: any distributors using 3.4.0 directly
can use --disable-libunwind.

I think this was decided this is not a bug, as anything changes the ABI is really not a bug if it is more 
correct.

I see the email was posted and nothing came out of it, basically this bug is invalid.  Not because it 
would change the ABI but the different between using libunwind and not using it is an ABI difference 
and an known one which means that you should be care full when trying to mix the binaries so closing 
as invalid.

With the patch

http://gcc.gnu.org/ml/gcc-patches/2004-08/msg01398.html

applied, the ABI-compliant 3rd party libunwind can be used in gcc without causing
any binary incompatibility. libunwind 0.98 from David Mosberger is one of such
libraries.
