When merging docsinstall and zfsboot updates to stable/9 it was discovered
that the slightly older dialog(1) requires --separate-output when using the
--checklist widget to force response to produce unquoted values (whereas in
stable/10 --checklist widget without --separate-output will only quote the
checklist labels in the response if the label is multi-word (contains any
whitespace).
Since these enhancements (see revisions 263956 and 264437) were developed
originally on 10, the --separate-output option was omitted. When merged to
stable/9, we (Allan Jude) and I found during testing that the "always-
quoting" of the response was causing things like struct interpolation to
fail (`f_struct device_$dev' would produce `f_struct device_\"da0\"' for
example -- literal quotes inherited from dialog(1) --checklist response).
To see the behavior, execute the following on stable/9 versus stable/10:
dialog --checklist disks: 0 0 0 da0 "" off da1 "" off
Check both items and hit enter. On stable/10, the response is:
da0 da1
On stable/9 the response is:
"da0" "da1"
If you use the --separate-output option, the response is the same for both:
da0
da1
So applying --separate-output on every platform until either one of two
things occurs 1) dialog(1,3) gets synchronized between stable/9, higher or
2) we drop support for stable/9.

Treat a zero length passed to ssleay_rand_add a no op: the existing logic
zeroes the md value which is very bad. OpenSSL itself never does this
internally and the actual call doesn't make sense as it would be passing
zero bytes of entropy.
Thanks to Marcus Meissner <meissner@suse.de> for reporting this bug.

This is a direct commit to stable/8 and stable/9. -HEAD and stable/10
already have this fix as part of OpenSSL 1.0.1g.
Create a symlink to sys/elf32.h, sys/elf64.h, and sys/elf_common.h.
When building libelf in the bootstrap stage this would include the tree
versions of, for example, sys/_types.h. This would work as long as the
tree's version of this file was close enough to the system's version of
the file. If, however, there was a change in the tree such that the location
of a typedef was moved this would cause problems. In this case the version
of sys/_types.h in the tree no longer defines __wchar_t and expects it to
to be defined in machine/_types.h, however we pick up machine/_types.h from
the system and find it is not defined there. The solution is to restrict the
parts of sys er include from the tree to those that are needed.
This fixes the recent Tinderbox failure.
MFC r237531:
Add the sys directory we create to the list of items to clean.
MFC r238741:
Don't ever build files depending on the directory where they are placed in.
It is obvious that its modification time will change with each such file
builded.
This bug cause whole libelf to rebuild itself each second make run
(and relink that files on each first make run) in the loop.
Don't pass a timeout of 0 ticks to pause() for a delay of less than 1
hz tick. On 8.x this results in an infinite sleep as pause() does not
support a delay of 0 ticks. Since all delay values are converted from
nanoseconds to ticks using a floor function, skipping the sleep for a
delay smaller than 1 tick is the more consistent than rounding up to a
single tick.
This is a direct commit to 8 and 9 as 10.x and later use pause_sbt()
instead.

The use case here is that /usr/src, /usr/doc, and /usr/ports

is possible (and happens quite often) that the included

for -RELEASE builds, but does happen for snapshot builds.)

Aliases are processed in numerical ascending order.

MFC r238468: sh: Expand assignment-like words specially for
export/readonly/local.
Examples:
export x=~
now expands the tilde
local y=$1
is now safe, even if $1 contains IFS characters or metacharacters.
For a word to "look like an assignment", it must start with a name followed
by an equals sign, none of which may be quoted.
The special treatment applies when the first word (potentially after
"command") is "export", "readonly" or "local". There may be quoting
characters but no expansions. If "local" is overridden with a function there
is no special treatment ("export" and "readonly" cannot be overridden with a
function).
If things like
local arr=(1 2 3)
are ever allowed in the future, they cannot call a "local" function. This
would either be a run-time error or it would call the builtin.
This matches Austin Group bug #351, planned for the next issue of POSIX.1.
As for the MFC, it is easy to depend on this feature inadvertently, and
adding this fixes a regression from stable/8 that may be apparent in things
like
local x=${y+a @}.

MFC r262501:
Refresh our implementation of OpenBSD's Blowfish password format.
Notable changes:
- Support of $2b$ password format to address a problem where very
long passwords (more than 256 characters, when an integer
overflow would happen and cause the length to wrap at 256).
- Updated pseudo code in comments to reflect the reality.
- Removed our local shortcut of processing magic string and rely
on the centralized and tigntened validation.
- Diff reduction from upstream.
For now we are still generating the older $2a$ format of password
but we will migrate to the new format once the format is formally
finalized.

Reland "Fix miscompile of MS inline assembly with stack realignment"
This re-lands commit r196876, which was reverted in r196879.
The tests have been fixed to pass on platforms with a stack alignment
larger than 4.
Update to clang side tests will land shortly.
Pull in r196986 from upstream llvm trunk (by Reid Kleckner):
Revert the backend fatal error from r196939
The combination of inline asm, stack realignment, and dynamic allocas
turns out to be too common to reject out of hand.
ASan inserts empy inline asm fragments and uses aligned allocas.
Compiling any trivial function containing a dynamic alloca with ASan is
enough to trigger the check.
XFAIL the test cases that would be miscompiled and add one that uses the
relevant functionality.
Pull in r202930 from upstream llvm trunk (by Hans Wennborg):
Check for dynamic allocas and inline asm that clobbers sp before building
selection dag (PR19012)
In X86SelectionDagInfo::EmitTargetCodeForMemcpy we check with MachineFrameInfo
to make sure that ESI isn't used as a base pointer register before we choose to
emit rep movs (which clobbers esi).
The problem is that MachineFrameInfo wouldn't know about dynamic allocas or
inline asm that clobbers the stack pointer until SelectionDAGBuilder has
encountered them.
This patch fixes the problem by checking for such things when building the
FunctionLoweringInfo.
Together, these commits fix the problem encountered in the devel/emacs
port on the i386 architecture, where a combination of stack realignment,
alloca() and memcpy() could incidentally clobber the %esi register,
leading to segfaults in the temacs build-time utility.

Pull in r203311 from upstream llvm trunk (by Arnold Schwaighofer):
ISel: Make VSELECT selection terminate in cases where the condition type has to
be split and the result type widened.
When the condition of a vselect has to be split it makes no sense widening the
vselect and thereby widening the condition. We end up in an endless loop of
widening (vselect result type) and splitting (condition mask type) doing this.
Instead, split both the condition and the vselect and widen the result.
I ran this over the test suite with i686 and mattr=+sse and saw no regressions.
Fixes PR18036.
With this fix the original problem case from the graphics/rawtherapee
port (posted in http://llvm.org/PR18036 ) now compiles within ~97MB RSS.

Add separate patch files for all the customizations we have currently
applied to our copy of llvm/clang. These can be applied in alphabetical
order to a pristine llvm/clang 3.4 release source tree, to result in the
same version used in FreeBSD.
This is intended to clearly document all the changes until now, which
mostly consist of cherry pickings from the respective upstream trunks,
plus a number of hand-written FreeBSD-specific ones. Hopefully those
can eventually be cleaned up and sent upstream too.

Merge the projects/clang-sparc64 branch back to head. This brings in
several updates from the llvm and clang trunks to make the sparc64
backend fully functional.
Apart from one patch to sys/sparc64/include/pcpu.h which is still under
discussion, this makes it possible to let clang fully build world and
kernel for sparc64.
Any assistance with testing this on actual sparc64 hardware is greatly
appreciated, as there will unavoidably be bugs left.
Many thanks go to Roman Divacky for his upstream work on getting the
sparc64 backend into shape.

Repair a few minor mismerges from r262261 in the clang-sparc64 project
branch. This is also to minimize differences with upstream.
