(update_frame_state): Handle ABI_MARKER_LINUX_INTERRUPT by calling linux_interrupt().
If c->abi_marker is non-zero, copy it to c->last_abi_marker.
(Logical change 1.89)
(access_reg) [HAVE_SYS_UC_ACCESS_H]: Sanitize and simplify this routine. Turns out
uc_access(3) works pretty much the way we need it, the only problem is that
the unwind info for getcontext() seems to be missing as of HP-UX 11.22.
(ia64_uc_access_reg): New function.
(ia64_uc_access_fpreg): Ditto.
(ia64_local_addr_space_init): Initialize "abi" member of local address space based
on the platform we're compiling on.
(Logical change 1.87)
nice backtrace, handling unwinding across signal handlers just fine. Main missing
piece right now is that unw_resume() doesn't work because uc_access(3) refuses to
write ar.bsp. Duh.

Rename: src/ia64/Lmk_cursor_i-ia64.c -> src/ia64/mk_Lcursor_i-ia64.c
(Logical change 1.87)
(remote_install_cursor): Enable the short-cut for Linux only. Since HP-UX uses
an opaque data-structure for ucontext_t, we can't play the same trick
there. Fix two typos: "> 0" -> ">= 0".
(unw_resume): Handle non-UNW_LOCAL_ONLY case simp;u bu calling
remote_install_cursor().
(Logical change 1.87)
support for HP-UX.
(access_nat): Check for uc-location and pass it on to ia64_put()/ia64_get() if
it is. Handle NaT-bit-saved-in-scratch-register only for Linux.
(ia64_access_reg): Change dprintf() into debug() statement.
(ia64_access_fpreg): Move fph-partition initialization code to ia64_scratch_loc().
Change dprintf() into debug() statement.
(Logical change 1.87)
(foo): Add some newlines for better readability.
(sighandler): Always declare as per Single UNIX Spec.
On HP-UX, use __uc_get_ip() to read the interruption IP.
(main): Always use sigaction() to install a signal handler, so we can
turn on the SA_SIGINFO flag.
(Logical change 1.87)
end up not using it.
(UNWIND_TBL_32BIT): New macro.
(struct unwind_header): Rename "unknown1" member to "header_version".
(tdep_find_proc_info) [HAVE_DLMODINFO]: Don't forget to initialize di.gp.
Check unwind-header version and format.
(Logical change 1.87)
Rename Gmk_cursor to mk_Gcursor, Lmk_cursor to mk_Lcursor so to avoid
scripts/make-L-files overwriting the (handcrafted) local version.
(EXTRA_DIST): Mention libunwind_la_SOURCES_os_hpux.
(Logical change 1.87)
Update code to work both for UNW_LOCAL_ONLY-version of the cursor and the
generic version of the cursor.
(ia64_install_cursor): New macro.
}(Logical change 1.85)
Update code to work both for UNW_LOCAL_ONLY-version of the cursor and the
generic version of the cursor.
(ia64_install_cursor): New macro.

and Linstall_cursor.S.
(Gmk_cursor_i_ia64_SOURCES): Rename from mk_cursor_i_ia64_SOURCES.
(Lmk_cursor_i_ia64_SOURCES): New mcro.
(Gcursor_i.h): Rename rule from cursor_i.h.
(Lcursor_i.h): New rule.
(noinst_PROGRAMS): Rename mk_cursor_i-ia64 to Gmk_cursor_i-ia64 and add
Lmk_cursor_i-ia64.
(BUILT_SOURCES): Ditto.
(Logical change 1.85)
more or less unchanged, but for the generic version, the save-location has been
expanded from a single word to two words. This is needed to accommodate 32-bit
targets and targets which require accessing the ucontext_t structure via uc_access(3).
Overall, this should be like a big no-op for Linux (apart from slowing down
the generic case a bit). However, at the moment, unw_resume() has not been updated
for the generic case (UNW_LOCAL_ONLY works fine though).
