            Bug ID: 64900
           Summary: gotools don't link on Solaris 11/x86
           Product: gcc
           Version: 5.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: go
          Assignee: ian at airs dot com
          Reporter: ro at gcc dot gnu.org
                CC: cmang at google dot com
              Host: i?86-*-solaris2.11
            Target: i?86-*-solaris2.11
             Build: i?86-*-solaris2.11

Unfortunately, the fix for PR go/64738 (not linking gotools statically) caused
Solaris 11/x86 bootstrap with gas/gld to fail:

/vol/gcc/bin/gld-2.24: gofmt: hidden symbol `_Unwind_GetLanguageSpecificData'
in
/var/gcc/regression/trunk/11-gcc-gas-gld/build/./gcc/libgcc_eh.a(unwind-dw2.o)
is referenced by DSO
/vol/gcc/bin/gld-2.24: final link failed: Bad value
collect2: error: ld returned 1 exit status
make[2]: *** [gofmt] Error 1

Adding -static-libgo back in does restore it.  Strangely, this is neither an
issue on Solaris 10/x86 with gas/gld nor on Solaris 11/SPARC with gas/gld.
