Re: RFC: cxxsupp test linkage on synth linux

The problem is that these missing functions come from a new separate library, libgcc_eh.a in gcc-lib.I can't seem to correctly specify that library's inclusion on the command line. Instead the only way to get it included is to edit synth.ld so that's probably what's required.

But why haven't people noticed this before? Versions of GCC 3.x before GCC 3.2.1 wouldn't work unless people were going back as far as gcc 2.9x.

With RedHat 9.0 (gcc-3.2.2), there are some problems with libgcc_eh.a included. Testsuite for linux-synthetic target breaks with:

make[1]: Leaving directory `/home/dejan/tmp/synth_build/infra/current'

In function `_Unwind_Find_FDE':
make: Leaving directory `/home/dejan/tmp/synth_build'
: undefined reference to `dl_iterate_phdr'

I was worried something like this might happen. We can do an explicit check for _GNUC_PATCHLEVEL_ but it would be nice to know if this is maybe something specific with the RH9 3.2.2 or not. Or 3.2.3 or GCC CVS for that matter. Anyone got those native tools and willing to try it quickly?

I'm not running RH9 myself I'm afraid.
