also unchanged from 1.9.2. Full list of changes between 1.9.4 and
earlier versions:

Note that the two security issues fixed in 1.9.4 (CVE-2016-2167 and
CVE-2016-2168) do not affect the version of Subversion in the FreeBSD
base system, since neither SASL nor Apache modules are enabled.

- xalloc(..) ensures that e will be non-null via malloc + err.
- `e` is already dereferenced above, so logically it's impossible
to hit the lower test without crashing if it was indeed NULL.

Pass dwarf-version to cc1as.

This should fix possible crashes when using -g in combination with
-save-temps.
Modify trapframe decoding to properly analyze trapframe.
Provide method for fixup_pc. It happens, that in some kernel
functions, the GDB stack frame decoder cannot determine both
func name and frame size. This is because these functions
either contain invalid instruction, or their format does
not match standard schema. Detect that scenarios and move
PC accordingly to jump into known function schema, which
GDB is able to parse.

Fix a symbol table handling bug in elfcopy: elfcopy puts .symtab,
.strtab and .shstrtab sections in the end of the output object. If
the input objects have more sections after any of these 3 sections,
the section table will be reordered, and in that case the section
symbols should be regenerated for relocations.
The bug is triggered since newer clang puts .strtab section in the
beginning of the object produced.

Add xo_set_file{,_h} functions
Fix LIBXO_* variables; add -L and -I as needed
add --disable-silent-rules and an explicit make; s/PACKAGE-NAME/PACKAGE_NAME/; add /download/ to 'url'

0.6.0:
Add --with-retain-size to set the size (in bits) of the retain hash buckets
Add The Argument Modifier ({a:})
Add retain and no-retain to --libxo
autoconf: Add test for monitor.h
Document quote heuristic
go deep with nroff backslashes

FreeBSD doesn't specifically list this as a supported error, and in some
configurations/versions of FreeBSD, this test will segfault as the memory
address might be evaluated in userspace, instead of in kernel space like
in NetBSD.

[libcxx] Enable noexcept for GCC 4.6 and greater
Summary:
This patch allows GCC 4.6 and above to use `noexcept` as opposed to
`throw()`.
Is it an ABI safe change to suddenly switch on `noexcept`? I imagine
it must be because it's disabled in w/ clang in C++03 but not C++11.

with libc++, which is also C++11. Also change one _Static_assert (which
is really C11) back into static_assert, like upstream.
This should help when compiling libcxxrt with newer versions of gcc,
which refuse to recognize any form of static assertions, if not
compiling for C++11 or higher.
While here, add -nostdinc++ to CFLAGS, to prevent picking up any C++
headers outside the source tree.
[X86] Emit a proper ADJCALLSTACKDOWN in EmitLoweredTLSAddr

Add <atomic> to ThreadPool.h, since std::atomic is used
Summary:
Apparently, when compiling with gcc 5.3.2 for powerpc64, the order of
headers is such that it gets an error about std::atomic<> use in
ThreadPool.h, since this header is not included explicitly. See also:

Fix this by including <atomic>. Patch by Bryan Drewery.

Merge ELF Tool Chain r3434:
Previously, elfcopy defines:
VMA: section virtual address
LMA: PHDR(p_vaddr)
While binutils(libbfd) defines:
VMA: section virtual address and PHDR(p_vaddr).
LMA: PHDR(p_paddr)
For elfcopy, p_paddr is considered not meaningful and is always set
to the same value as p_vaddr.
elfcopy was implemented that way because I thought p_paddr is not
used/meaningful according to the ELF ABI. However it turned out
p_paddr is at least used in some ELF files, e.g. the FreeBSD kernel.
This change made elfcopy treat p_paddr as LMA, same as libbfd.
(However, some VMA/LMA related command line option still need tweaking
to make them compatible with binutils objcopy. This will be improved
later)

Archive member handling works again

Update dirdeps.mk - much improved startup time.
Update meta.stage.mk - avoid ln when chmod required.
struct tcpstat, because the structure can be zeroed out by netstat(1) -z,
and of course running connection counts shouldn't be touched.
Place running connection counts into separate array, and provide
separate read-only sysctl oid for it.
ftruncate/11, open/20, and truncate/11 copy sleep(1) to a temporary file on the
target filesystem, execute the binary, then expect a result. This doesn't work
with scenarios where the target binary cannot be executed, e.g. the filesystem
was mounted with -o noexec.
Ensure the filesystem hasn't been mounted with -o noexec for the testcases
before executing them.

Pull in r255585 from upstream libc++ trunk (by Eric Fiselier):
Fix various GCC mis-configurations for newer versions.
This patch goes through and enables C++11 and C++14 features for newer GCC's.
The main changes are:
1. Turn on variable templates. (Uses __cpp_variable_templates)
2. Assert atomic<Tp> is trivially copyable (Uses _GNUC_VER >= 501).
3. Turn on trailing return support for GCC. (Uses _GNUC_VER >= 404)
4. XFAIL void_t test for GCC 5.1 and 5.2. Fixed in GCC 6.
Together, these should fix building clang 3.8.0 as part of building
world with recent versions of gcc (e.g. the devel/*-xtoolchain-gcc
ports).
