Update.
2002-02-28 Jakub Jelinek <jakub@redhat.com> * elf/rtld.c (_rtld_global): Remove .protected. (_rtld_local): Strong alias to _rtld_global. * elf/Makefile (CFLAGS-.os): Add -D_RTLD_LOCAL if compiling rtld only .os object. * sysdeps/generic/ldsodefs.h (GL): If SHARED and _RTLD_LOCAL, use _rtld_local instead of _rtld_global. (_rtld_local): Add hidden extern, possibly in .sdata section. * configure.in: Add tests for visibility attribute and .sdata. * config.h.in: Add HAVE_VISIBILITY_ATTRIBUTE and HAVE_SDATA_SECTION. * sysdeps/alpha/dl-machine.h: Use _rtld_local instead of _rtld_global. * sysdeps/arm/dl-machine.h: Likewise. * sysdeps/generic/ldsodefs.h: Likewise. * sysdeps/hppa/dl-machine.h: Likewise. * sysdeps/cris/dl-machine.h: Likewise. * sysdeps/i386/dl-machine.h: Likewise. * sysdeps/ia64/dl-machine.h: Likewise. * sysdeps/m68k/dl-machine.h: Likewise. * sysdeps/mips/mips64/dl-machine.h: Likewise. * sysdeps/mips/dl-machine.h: Likewise. * sysdeps/sparc/sparc32/dl-machine.h: Likewise. * sysdeps/sparc/sparc64/dl-machine.h: Likewise. * sysdeps/sh/dl-machine.h: Likewise. * sysdeps/s390/s390-32/dl-machine.h: Likewise. * sysdeps/s390/s390-64/dl-machine.h: Likewise. * sysdeps/x86_64/dl-machine.h: Likewise.
