actually work, linking of libgcc_s.so.1 on ia64 will fail with:
unwind-ia64.So(.text+0x1762): In function `_Unwind_FindEnclosingFunction':
: undefined reference to `_Unwind_FindTableEntry'
unwind-ia64.So(.text+0x1d82): In function `uw_frame_state_for':
: undefined reference to `_Unwind_FindTableEntry'
/usr/bin/ld: libgcc_s.so.1: hidden symbol `_Unwind_FindTableEntry' isn't defined
Repair this by not hiding the _Unwind_FindTableEntry symbol; on FreeBSD,
it is in libc, not in libgcc.

thread specific informations.
In order to do that, and in order to avoid KBI breakage with existing
infrastructure the following semantic is implemented:
- For live programs, a new member to the PT_LWPINFO is added (pl_tdname)
- For cores, a new ELF note is added (NT_THRMISC) that can be used for
storing thread specific, miscellaneous, informations. Right now it is
just popluated with a thread name.
GDB, then, retrieves the correct informations from the corefile via the
BFD interface, as it groks the ELF notes and create appropriate
pseudo-sections.

Not doing so may cause all sorts of random libraries to expose
libcompiler_rt's functions, which should of course not be done.

to 3 bytes of uninitialized garbage; as a result, .ko files could
change vary between builds.

read_initial_length detects pointer size by checking first
4 bytes of .debug_line and stores it in struct comp_unit_head *
passed to it as second argument. By passing NULL to a
read_initial_length we ignore actual pointer size (8 bytes) and
use default (4 bytes) which results in wrong offsets of header fields.
asctime.c:
* Set errno to EINVAL and return "??? ??? ?? ??:??:?? ????\n" if
asctime_r is called with a NULL struct tm pointer. (Note that
asctime_r is called by ctime_r and asctime; asctime is called by
ctime.)
localtime.c:
* Set errno to EINVAL and return WRONG if time1 is called with a
NULL struct tm pointer; avoid dereference if a NULL struct tm
pointer is passed to timelocal, timegm, or timeoff. (Note that
time1 is called by mktime, timegm, and timeoff; mktime is called
by timelocal.)
* more core-avoidance work
* Change to set timezone and altzone based on time types with
greatest transition times (for the benefit of Asia/Seoul).
zic.8:
* Warning about case-sensitivity of names, but not of abbrevations
zic.c:
* Conditionally output extra types with most-recently-use offsets
last (for use by systems with pre-2011 versions of localtime.c,
helping to ensure that globals "altzone and "timezone" get set
correctly).
The code has been running for nearly four weeks on my laptop running
FreeBSD 8.1 without a problem.

make it like xArg because they are different ('x' doesn't accept sign,
but 'r' does).
This fixes some warnings when building DDB with clang.
With help from: rdivacky
Make "clang -print-multi-os-directory" return "." on amd64, matching
gcc's behaviour. This is needed because some ports use the option to
determine the installation directory for their libraries.

stack unwinding, instead of naively trying to check the instruction at
that location. This fixes signal handling in threaded applications after
recent changes regarding unwinding in libthr. While here, clean up our
MD_FROB_UPDATE_CONTEXT() implementation a little.
