The mandoc search database generation uses each page's inode number as
a hash key to index hard linked pages only once. However, it also
processed the pages ordered by hash key resulting in effectively non-
deterministic output.
Instead:
1) provide fts_open() with a comparison function to process directories
and files in a deterministic order
2) in addition to the existing hash, insert pages into a linked list
which will be sorted (by virtue of 1)
3) iterate over pages by the list in 2, instead of hash order
I will work on upstreaming this change.

Don't warn about valid time zone abbreviations. POSIX
through 2000 says that an abbreviation cannot start with ':', and
cannot contain ',', '-', '+', NUL, or a digit. POSIX from 2001
on changes this rule to say that an abbreviation can contain only
'-', '+', and alphanumeric characters from the portable character
set in the current locale. To be portable to both sets of rules,
an abbreviation must therefore use only ASCII letters." Adapted

This commit is from John Marino in dragonfly with the following commit log:
====
This was a CTYPE encoding error involving consecutive points of the same
ctype. It was reported by myself to Illumos over a year ago but I was
unsure if it was only happening on BSD. Given the cause, the bug is also
present on Illumos.
Basically, if consecutive points were of the exact same ctype, they would
be defined as a range regardless. For example, all of these would be
considered equivalent:
<A> ... <C>, <H> (converts to <A> .. <H>)
<A>, <B>, <H> (converts to <A> .. <H>)
<A>, <J> ... <H> (converts to <A> .. <H>)
So all the points that shouldn't have been defined got "bridged" by the
extreme points.
The effects were recently reported to FreeBSD on PR 213013. There are
countless places were the ctype flags are misdefined, so this is a major
fix that has to be MFC'd.

The blacklistd daemon expects to see a message on stdout, instead
of just relying on the exit value from any invoked programs.
Change the pf filtering to create multiple filters, attached under
a the "blacklist/*" anchor point. This prevents the filtering for
each port's filtering rule from overwriting the previously installed
filtering rule. Check for an existing filtering rule for each port,
so the installation of a given filtering rule only happens once.
Reinstalling the same rule resets the counters for the pf rule, and
we don't want that.

[x86] don't try to create a vector integer inst for an SSE1 target
(PR30512)
This bug was introduced with:
http://reviews.llvm.org/rL272511
We need to restrict the lowering to v4f32 comparisons because that's
all SSE1 can handle.
This should fix:
https://llvm.org/bugs/show_bug.cgi?id=28044
This avoids a "Do not know how to custom type legalize this operation"
error when building the multimedia/ffmpeg port on i386 with SSE enabled.
build can break when different source files create the same target
files (case-insensitivity speaking). This is the case for object
files compiled with -fpic and shared libraries. The former uses
an extension of ".So", and the latter an extension ".so". Rename
shared object files from *.So to *.pico to match what NetBSD does.

[PPC] Claim stack frame before storing into it, if no red zone is

Unlike PPC64, PPC32/SVRV4 does not have red zone. In the absence of

stack frame first before storing into it.

Add ISD::EH_DWARF_CFA, simplify @llvm.eh.dwarf.cfa on Mips, fix on
PowerPC
LLVM has an @llvm.eh.dwarf.cfa intrinsic, used to lower the
GCC-compatible __builtin_dwarf_cfa() builtin. As pointed out in
PR26761, this is currently broken on PowerPC (and likely on ARM as
well). Currently, @llvm.eh.dwarf.cfa is lowered using:
ADD(FRAMEADDR, FRAME_TO_ARGS_OFFSET)
where FRAME_TO_ARGS_OFFSET defaults to the constant zero. On x86,
FRAME_TO_ARGS_OFFSET is lowered to 2*SlotSize. This setup, however,
does not work for PowerPC. Because of the way that the stack layout
works, the canonical frame address is not exactly (FRAMEADDR +
FRAME_TO_ARGS_OFFSET) on PowerPC (there is a lower save-area offset
as well), so it is not just a matter of implementing
FRAME_TO_ARGS_OFFSET for PowerPC (unless we redefine its semantics --
We can do that, since it is currently used only for
@llvm.eh.dwarf.cfa lowering, but the better to directly lower the CFA
construct itself (since it can be easily represented as a
fixed-offset FrameIndex)). Mips currently does this, but by using a
custom lowering for ADD that specifically recognizes the (FRAMEADDR,
FRAME_TO_ARGS_OFFSET) pattern.
This change introduces a ISD::EH_DWARF_CFA node, which by default
expands using the existing logic, but can be directly lowered by the
target. Mips is updated to use this method (which simplifies its
implementation, and I suspect makes it more robust), and updates
PowerPC to do the same.
Fixes PR26761.

[PowerPC] Don't spill the frame pointer twice
When a function contains something, such as inline asm, which
explicitly clobbers the register used as the frame pointer, don't
spill it twice. If we need a frame pointer, it will be saved/restored
in the prologue/epilogue code. Explicitly spilling it again will
reuse the same spill slot used by the prologue/epilogue code, thus
clobbering the saved value. The same applies to the base-pointer or
PIC-base register.
Partially fixes PR26856. Thanks to Ulrich for his analysis and the
small inline-asm reproducer.
[PowerPC] Add support for -mlongcall
The "long call" option forces the use of the indirect calling
sequence for all calls (even those that don't really need it). GCC
provides this option; This is helpful, under certain circumstances,
for building very-large binaries, and some other specialized use
cases.
Fixes PR19098.

This fixes building the multimedia/libx264 port on i386.
the end of libc++'s <exception>. This is a workaround for building
Firefox, which generates a rather convoluted maze of standard library
wrapper headers, and this leads to an unfortunate sequence of:
1. wrapper <new> includes libc++ <new>,
2. which includes wrapper <exception>,
3. which includes libc++ <exception>,
4. which includes wrapper <cstdio> (because of -fno-exception),
5. which includes libc++ <new> again,
6. which includes mozalloc.h,
7. which tries to declare operator new with std::bad_alloc,
8. which gives an error because std::bad_alloc is not yet defined.
The <new> inclusion at step 5 does nothing, because the header guard for
<new> was already encountered in step 1. Then when moz_alloc.h tries to
use std::bad_alloc, it is not yet defined, because we are still busy
processing <exception> (where this class is defined) from step 3.
Mozilla has https://bugzilla.mozilla.org/show_bug.cgi?id=1269171 for
this, reported by Jan Beich (jbeich@), but when the fix for it is
applied to Firefox, we get into another, similar problem situation:
1. some header includes wrapper <exception>,
2. which includes libc++ <exception>,
3. which includes wrapper <cstdio> (because of -fno-exceptions),
4. which includes mozalloc.h,
5. which includes wrapper <new>,
6. which includes libc++ <new>,
7. which gives an error defining std::bad_alloc, because std::exception
is not yet defined.
At step 3, we were at the top of libc++'s <exception>, and at that point
std::exception is not yet defined. At step 6, <new> does include
<exception> again, but similar to step 5 in the previous problem case,
the header guard was already encountered, so the whole header is
skipped.
In upstream libc++'s later revisions r279744 and r279763, the reason for
including <cstdio> and <cstdlib> was nullified again, but these commits
are rather large and intrusive. Therefore, move the includes to the
bottom of the file, just before where they are needed. At that point,
std::exception is already fully defined.
