Update.
2003-12-02 David Mosberger <davidm@hpl.hp.com> * sysdeps/ia64/elf/initfini.c: Add unwind info. * sysdeps/ia64/dl-machine.h (elf_machine_matches_host): Mark with attribute "unused". (elf_machine_dynamic): Mark with attributes "unused" and "const". (elf_machine_runtime_setup): Likewise. * sysdeps/generic/dl-fptr.c (make_fptr_table): Mark with attribute "always_inline". * sysdeps/ia64/dl-machine.h (__ia64_init_bootstrap_fdesc_table): Likewise. * configure.in: Check whether compiler has libunwind support. * config.make.in (have-cc-with-libunwind): New variable. * config.h.in (HAVE_CC_WITH_LIBUNWIND): New macro. * Makeconfig (gnulib): If have-cc-withh-libunwind is "yes", also mention -lunwind. 003-11-12 David Mosberger <davidm@hpl.hp.com> * sysdeps/unix/sysv/linux/ia64/sysdep.h: Define DO_CALL_VIA_BREAK. Redefine DO_CALL to use vdso if supported, otherwise DO_CALL_VIA_BREAK. Likewise for DO_INLINE_SYSCALL. Make INTERNAL_SYSCALL use DO_INLINE_SYSCALL. * sysdeps/unix/sysv/linux/ia64/vfork.S: Use DO_CALL_VIA_BREAK() instead of DO_CALL(). * sysdeps/unix/sysv/linux/ia64/clone2.S: Use break directly instead of DO_CALL(). * sysdeps/unix/sysv/linux/ia64/brk.S (__curbrk): Restructure it to take advantage of DO_CALL() macro. * sysdeps/unix/sysv/linux/ia64/setcontext.S: Likewise. * sysdeps/unix/sysv/linux/ia64/getcontext.S: Likewise. * elf/rtld.c (dl_main): Restrict dl_sysinfo_dso check to first program header. On ia64, the check failed previously because there are two program headers. * sysdeps/generic/s_nexttowardf.c: Likewise. * math/bug-nexttoward.c: New file.
