help needed for defining hppa __clz_tab gcc-compat symbol

[Randolph Chung <tausq@debian.org>]

Hi all,

I've been working with Carlos to try to get the libgcc-compat patch put
together for hppa. Somehow it's not quite working. Hope someone can help
:)

The missing symbol in our case is __clz_tab. This is an array instead of
a function like the case for other archs.

I've created a libgcc-compat.c that has something like this:

#if SHLIB_COMPAT(libc, GLIBC_2_2, GLIBC_2_2_6)
symbol_version (__clz_tab_internal, __clz_tab, GLIBC_2.2);
typedef unsigned int UQItype  __attribute__ ((mode (QI)));
static const UQItype __clz_tab_internal[] = { ... }
#endif

The resulting libc.so.6 has:
legolas[8:03] obj% readelf -a ./libc.so.6|grep clz
    94: 0011f760   256 OBJECT  LOCAL  DEFAULT   13 __clz_tab_internal
    95: 0011f760   256 OBJECT  LOCAL  DEFAULT   13 __clz_tab@GLIBC_2.2
  3695: 00134df0   256 OBJECT  LOCAL  HIDDEN   13 __clz_tab

but this still triggers errors:

legolas[8:05] obj% LD_LIBRARY_PATH=`pwd` ldd /usr/src/chroot-stable/usr/bin/wget
        libssl.so.0.9.6 => /usr/lib/libssl.so.0.9.6 (0x40029000)
        libcrypto.so.0.9.6 => /usr/lib/libcrypto.so.0.9.6 (0x4006c000)
        libdl.so.2 => /lib/libdl.so.2 (0x4015b000)
        libc.so.6 => /usr/src/glibc/glibc-package/hppa-linux/obj/libc.so.6 (0x4016e000)
        /lib/ld.so.1 => /lib/ld.so.1 (0x40000000)
        
legolas[8:05] obj% LD_LIBRARY_PATH=`pwd` /usr/src/chroot-stable/usr/bin/wget
/usr/src/chroot-stable/usr/bin/wget: relocation error: /usr/src/chroot-stable/usr/bin/wget: undefined symbol: __clz_tab

What am i missing?

thanks
