As promised, here a summary of what the patches do.
Thanks,

------------------
GCC patches:
Fix unwind info for C startup/finalization code so that it can be
unwound:
config/ia64/crtbegin.asm:
(__dso_handle): Really define it as a BSS symbol.
(__do_global_dtors_aux): Add unwind directives.
(__do_jv_register_classes): Likewise.
config/ia64/crtend.asm:
(__do_global_ctors_aux): Add unwind directives.
Fix two compiler bugs which caused bad unwind info for sibcalls
and for functions which had multiple copies of the epilogue (patches
by Jim Wilson).
config/ia64/ia64.c:
(ia64_expand_epilogue): Mark "alloc" in front of a sibcall as
frame-related.
(process_set): Generate unwind directives for sibcall "alloc".
emit-rtl.c:
(emit_copy_of_insn_after): Also copy frame-related predicate.
Fix GCC for libunwind.
gcc.c:
(init_spec): Also specific -lunwind for the shared case.
------------------
GLIBC patches:
Make GLIBC buildable with a libunwind-enabled GCC (patches by HJ Lu):
Makeconfig: Use $(static-gnulib) instead of $(gnulib).
If compiler is libunwind-enabled, link against -lunwind.
Makerules:
(LDLIBS-c.so): Use $(libc.so-gnulib) instead of $(gnulib).
config.h.in:
(HAVE_CC_WITH_LIBUNWIND): New macro.
config.make.in:
(have-cc-with-libunwind): New macro.
configure.in:
Add a check to see whether compiler is libunwind-enabled.
Fix unwind-info for NPTL _init/_fini routines.
nptl/sysdeps/unix/sysv/linux/ia64/pt-initfini.c:
(_init): Add unwind directives.
(_fini): Likewise.
------------------
Binutils/GAS patch:
Fix handling of psp-relative offsets (patch by Jim Wilson).
tc-ia64.c:
(ENCODED_PSP_OFFSET): New macro.
Fix off-by-16 bug by using ENCODED_PSP_OFFSET() macro to
calculate all psp-relative offsets.
