contains the libraries for Address Sanitizer (asan), Undefined Behavior
Sanitizer (ubsan) and Profile Guided Optimization.
ASan is a fast memory error detector. It can detect the following types
of bugs:
Out-of-bounds accesses to heap, stack and globals
Use-after-free
Use-after-return (to some extent)
Double-free, invalid free
Memory leaks (experimental)
Typical slowdown introduced by AddressSanitizer is 2x.
UBSan is a fast and compatible undefined behavior checker. It enables a
number of undefined behavior checks that have small runtime cost and no
impact on address space layout or ABI.
PLEASE NOTE: the sanitizers still have some rough edges on FreeBSD,
particularly on i386. These will hopefully be smoothed out in the
coming time.

issue. lib/atf isn't a prereq_lib, since it isn't required for other
libraries to build. Remove it. The old kludge of always building it
had effectively been retired. Since we don't want to build the
libraries with the tests when we're bootstrapping, invent
MK_TESTS_SUPPORT which normally defaults to the current MK_TESTS
value, except when explicitly defined. Make lib/atf depend on it being
yes. When building the libraries set MK_TESTS to no, and
MK_TESTS_SUPPORT to the current value of MK_TESTS so that later stages
of the build work correctly. This should fix (and does for me)
people's issues with parallel builds racing between lib/atf and
libexec/atf. Since lib/atf is built during the libraries phase, the
race disappears.
This allows us to use libevent for other application in the future.
For now libevent is still INTERNALLIB and no shared library is installed.

during SUBDIR_PARALLEL builds. This augments the coarse .WAIT mechanism,
which is still useful if you've got a situation such as "almost everything
depends on A and B".
Because the parallel subdir mechanism uses non-obvious mangling of
target names, which should probably remain a private detail of the
implementation, it's not easy to do things like "libfoo: libbar", so
instead the new mechanism lets you set a variable that lists dependencies:
SUBDIR_DEPEND_libfoo= libgroodah libpouet
Note that while I'm using libraries as an example here, it really has
nothing to do with the generated library files. This is really saying
"build in directory libfoo after building in the libgroodah and libpouet
directories."
This updates lib/Makefile with dependency information based on the old
almost-accurate comment block and by combing through lib/* makefiles
looking for LDADD dependencies to other libraries within lib/*.

all the SUBDIR entries in parallel, instead of serially. Apply this
option to a selected number of Makefiles, which can greatly speed up the
build on multi-core machines, when using make -j.
This can be extended to more Makefiles later on, whenever they are
verified to work correctly with parallel building.
I tested this on a 24-core machine, with make -j48 buildworld (N = 6):

E.g. the build was approximately 45% faster in real time. On machines
with less cores, or with lower -j settings, the speedup will not be as
impressive. But at least you can now almost max out a machine with

IPX was a network transport protocol in Novell's NetWare network operating
system from late 80s and then 90s. The NetWare itself switched to TCP/IP
as default transport in 1998. Later, in this century the Novell Open
Enterprise Server became successor of Novell NetWare. The last release
that claimed to still support IPX was OES 2 in 2007. Routing equipment
vendors (e.g. Cisco) discontinued support for IPX in 2011.
Thus, IPX won't be supported in FreeBSD 11.0-RELEASE.

FreeBSD systems usually implemented this as a third party module and
our implementation hasn't played as nicely with the old way as it could
have.
To that end:
* Rename the iconv* symbols in libc.so.7 to have a __bsd_ prefix.
* Provide .symver compatability with existing 10.x+ binaries that
referenced the iconv symbols. All existing binaries should work.
* Like on Linux/glibc systems, add a libc_nonshared.a to the ldscript
at /usr/lib/libc.so.
* Move the "iconv*" wrapper symbols to libc_nonshared.a
This should solve the runtime ambiguity about which symbols resolve
to where. If you compile against the iconv in libc, your runtime
dependencies will be unambiguous.
Old 9.x libraries and binaries will always resolve against their
libiconv.so.3 like they did on 9.x. They won't resolve against libc.
Old 10.x binaries will be satisified by the .symver helpers.
This should allow ports to selectively compile against the libiconv
port if needed and it should behave without ambiguity now.

Move the installation of /usr/tests/lib/Kyuafile from src/tests/lib/
to src/lib/. This is to keep the src/tests/ hierarchy unaware of the
rest of the tree, which makes things clearer in general. In particular:
1) Everything related to the construction of /usr/tests/lib/ is kept
in src/lib/. There is no need to think about different directories
and how they relate to each other. (The same applies for libexec,
usr.bin, etc. but these are not yet handled.)
2) src/tests becomes the place to keep cross-functional test programs
and nothing else, which also helps in simplifying things.

There is no reason to keep the two knobs separate: if tests are
enabled, the ATF libraries are required; and if tests are disabled,
the ATF libraries are not necessary. Keeping the two just serves
to complicate the build.

This splits that functionality and enables the parts that shouldn't
interfere with the port by default.
WITH_ICONV (now on by default) - adds iconv.h, iconv_open(3) etc.
WITH_LIBICONV_COMPAT (off by default) adds the libiconv_open etc API, linker
symbols and even a stub libiconv.so.3 that are good enough to be able
to 'pkg delete -f libiconv' on a running system and reasonably expect it
to work.
I have tortured many machines over the last few days to try and reduce
the possibilities of foot-shooting as much as I can. I've successfully
recompiled to enable and disable the libiconv_compat modes, ports that use
libiconv alongside system iconv etc. If you don't enable the
WITH_LIBICONV_COMPAT switch, they don't share symbol space.
This is an extension of behavior on other system. iconv(3) is a standard
libc interface and libiconv port expects to be able to run alongside it on
systems that have it.
