42decb4196 Seperate the Paul Kranenburg a.out rtld stuff into a stand-alone area away
from the gpl ld code.  This is part 2 of something that I began in 1996.
A repository copy has happened behind cvs's back.

08bdd3d27d Get rid of the dynamic linker's internal malloc package, and arrange
things so that it uses the same malloc as is used by the program
being executed.  This has several advantages, the big one being
that you can now debug core dumps from dynamically linked programs
and get useful information out of them.  Until now, that didn't
work.  The internal malloc package placed the tables describing
the loaded shared libraries in a mapped region of high memory that
was not written to core files.  Thus the debugger had no way of
determining what was loaded where in memory.  Now that the dynamic
linker uses the application's malloc package (normally, but not
necessarily, the system malloc), its tables end up in the regular
heap area where they will be included in core dumps.  The debugger
now works very well indeed, thank you very much.

Also ...

Bring the program a little closer to conformance with style(9).
There is still a long way to go.

Add minimal const correctness changes to get rid of compiler warnings
caused by the recent const changes in <dlfcn.h> and <link.h>.

Improve performance by eliminating redundant calculations of symbols'
hash values.

9453d60b10 Fixed `make depend' and related bogons. LDFLAGS was used for
ld-specific flags.  LDFLAGS is really for ld-related flags for cc,
not for ld, and some flags, e.g., -Bshareable, mean completely
different things to cc and ld.  Having the wrong things in LDFLAGS
also broke the standard ${PROG} target.  This was kludged around
by using a special rule that depended on LDFLAGS being bogus.
Fixing `make depend' broke the special rule but fixed the standard
rule (except in the DESTDIR case, which was handled more strictly
here than elsewhere).

1130b656e5 Make the long-awaited change from $Id$ to $FreeBSD$
This will make a number of things easier in the future, as well as (finally!)
avoiding the Id-smashing problem which has plagued developers for so long.

Boy, I'm glad we're not using sup anymore.  This update would have been
insane otherwise.

5584286a91 Update to handle new version ld.so.hints and info in executable for
configurable fallback search paths, as well as new crt interface version.

Also:
 - even faster getenv(), get all environment variable settings in a single
   pass.
 - ldd printf-like format specifications
 - minor code cleanups, one vsprintf -> vsnprintf (harmless)

The library search sequence is a little more complete now. Before,
it'd search $LD_LIBRARY_PATH (by opendir/readdir/closedir), then read
the hints file, then read /usr/lib (again by scanning thr directory).  It
would then fail if there was no "found" library.

Now, it does LD_LIBRARY_PATH and the hints file the same, but then uses
a longer fallback path.  The -R path is fetched from the executable if
specified at build time, the ldconfig path is appended, and /usr/lib is
appended to that. Duplicates are suppressed.  This means that simply
placing a new library in /usr/local/lib will work (the same as it did in
/usr/lib) without needing ldconfig -m.  It will find it quicker if the
ldconfig is run though.

Similar changes have been made to the NetBSD ld.so, but ours is rather
different now due to John Polstra's speedups and fixes from a while back.

The ldd printf-like format support came direct from NetBSD.

87d0dcafca Use `install -C' instead of lots of shell commands to install ld.so
as atomically as possible.

(Immutable targets can't be renamed without opening a window when
neither the source nor the target is immutable.  Perhaps there
should be a rename_immutable syscall to do this if unsetting the
immutable flags would work.)

c79eac4c4c Weak symbol support from NetBSD. This should bring us in sync with the
NetBSD ld code except for local changes for dlopen() and friends and
the hashing on the minor value of the shlibs.  We should be binary
compatible now with all their libraries.

2577a8acef Add dependencies on libraries to DPADD. Someday this should be done
automagically.  -lfoo has to be right to work, but ${LIBFO0} is too
easy to forget or misspell; nothing checks it and it should be
different for shared libraries.

3507018b5b Due to the deletion of the gcc support from libc we need again the
-lgcc_pic library. rtld uses the udivd3 routine from it.
Repeat the bug by simply compiling ld on current.

09e3d49d92 This is Paul K's latest set of ld changes. A commit was necessary at this
late stage due to the fact that link.h was copyright Sun Microsystems.

This version of ld sync's us up with NetBSD's ld and supports compatablily
with NetBSD's -[zZ] flags (which we had reversed).  Compiling with this
new ld will give you RRS warnings for libraries which do not contain .type
infomation - these wsarnings are harmless and will go away as soon as you
recompile your libraries (cd /usr/src; make libraries).
