Implemented symbol memorizing to reduce the number of calls to lookup(),
making relocation go faster. While relocating a given shared object,
the dynamic linker maintains a memorizing vector that is directly
indexed by the symbol number in the relocation entry. The first time a
given symbol is looked up, the memorizing vector is filled in with a
pointer to the symbol table entry, and a pointer to the so_map of the
shared object in which the symbol was defined. On subsequent uses of
the same symbol, that information is retrieved directly from the
memorizing vector, without calling lookup() again.
A symbol that is referenced in a relocation entry is typically
referenced in many relocation entries, so this memorizing reduces the
number of calls to lookup() dramatically. The overall improvement in
the speed of dynamic linking is also dramatic -- as much as a factor of
three for programs that use many shared libaries.

bsd.man.mk when I change the latter to use `::' instead of `:'
dependencies. (bsd.man.mk is included because NOMAN isn't defined.
The maninstall target is supposed to be private to bsd.man.mk so
bsd.man.mk doesn't bother testing if it is already defined. The
test for redefinition in Makefile.dev was too early to do anything.)
Change install target to a beforeinstall target (perhaps there should
be an `extrainstall' target so that Makefiles don't have to abuse
one of beforeinstall, install, realinstall or afterinstall). Don't
bother testing for the install target already being defined. Rewrite
the shell loop as a make loop (this reduces the time for installing
groff from 78s to 65s here).
include this in the old makefiles.
I intended to fix only the private maninstall rule but found a lot of
other bogons and bugs:
- strong resistance to installing the program anywhere other than
${DESTDIR}/usr/bin (first, ../../Makefile.inc was not included.
../Makefile/inc was redundantly included instead. Second, /usr/bin
was hard coded).
- the owner, group and permissions were hard coded.
- the man page was installed twice.
- MANDEPEND wasn't necessary.
- calculations to determine the obj directory weren't necessary.
- there were unnecessary private rules for depend, rcsfreeze and tags.
We don't support the rcsfreeze target.
- there was an extra, bogus, rule for `all'.
The final version uses suffix rules to eliminate the remaining verboseness
involving directories (${.CURDIR}) and to potentially allow multiple
shell programs in one directory.

instead of the uninitialized one $(DEVICE).
I hoped these changes would fix some of the large runtime macro processing
bugs, but they seem to only fix some small build-time macro substitution
bugs. E.g., `man ms' now tells you to invoke groff with the flags `-ms'
instead of the bogus flags `-m'; `man groff now tells you that the default
device is `ps' instead of the bogus device `'.
shared library. Formerly, the message looked like this:
ld.so: run: libjdp1.so.1.0: Undefined error: 0
The new message looks like this:

(Where "run" is the name of the program being executed.)

symbols.
An easy example to see this is to develop an X program which links
against Xt, but doesn't add -lX11 to the link line. It will link fine,
but cause run-time errors by ld.so because of missing symbols used by Xt
defined in X11. This patch makes the errors more readable.

subdirectories that have the same name not patch the same file. For example
a diff with patches to Makefile, des/Makefile, usr.bin/Makefile would attempt
to patch Makefile three times.
"update -jHEAD" when a file has been added on the specified tag.
It doesn't actually make cvs 'handle' it, it just stops it from dying
and leaving stray locks and other wreckage.
This was suggested by the CVS maintainers, and is in cvs-1.5.1-950901.
1: It stops invalid files being created in the cvs tree
2: It stops the import from aborting without mailing a commit message..
The first is simple, it opens the file for reading before touching the
repository, and the second catches the pieces when it hits an unreadable
file rather than just aborting mid-way through, leaving the repository in
a bit mess.

Change c++rt0.o to avoid using atexit to call destructors, allowing dlclose to

Change interface between crt0 and ld.so to allow crt0 to call a function on

These changes are backwards compatible. Old binaries will work with the new

cpio/copyout.c:
Don't output a file if the major, minor or totality of its rdev would be
truncated. Print a message about the skipped files to stderr but don't
report the error in the exit status. cpio's abysmal error handling doesn't
allow continuing after an error, and the rdev checks had to be misplaced
to avoid the problem of returning an error code from routines that return
void.
pax/pax.h:
Use the system macros for major(), minor() and makedev().
pax already checks _all_ output conversions for overflow. This has the
undesirable effect that failure to convert relatively useless fields
such as st_dev for regular files causes files not to be output. pax
doesn't report exactly which fields couldn't be converted.
tar/create.c:
Don't output a file if the major or minor its rdev would be truncated.
Print a message about the skipped files to stderr and report the error
in the exit status.
tar/tar.c:
For not immediately fatal errors, exit with status 1, not the error count
(mod 256).
All:
Minor numbers are limited to 21 bits in pax's ustar format and to 18
bits in archives created by gnu tar (gnu tar wastes 3 bits for padding).
pax's and cpio's ustar format is incompatible with gnu tar's ustar
format for other reasons (see cpio/README).
