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.
