GNU libtool checks the output from invoking the linker with --version
and --help, in order to determine the linker "flavour" and the command-
ine arguments to use for various link operations (e.g. generating shared
libraries). To detect GNU ld it looks for the strings "GNU" and
"supported targets:.*elf". Since LLD is compatible with GNU ld we
include those same strings to fool libtool.
Quoting from a comment in the change:
This is somewhat ugly hack, but in reality, we had no choice other
than doing this. Considering the very long release cycle of Libtool,
it is not easy to improve it to recognize LLD as a GNU compatible
linker in a timely manner. Even if we can make it, there are still a
lot of "configure" scripts out there that are generated by old
version of Libtool. We cannot convince every software developer to
migrate to the latest version and re-generate scripts. So we have
this hack.

- Add a new "qsize" parameter in audit_control and the getacqsize(3) API to
query it, allowing to set the kernel's maximum audit queue length.
- Add support to push a mapping between audit event names and event numbers
into the kernel (where supported) using new A_GETEVENT and A_SETEVENT
auditon(2) operations.
- Add audit event identifiers for a number of new (and not-so-new) FreeBSD
system calls including those for asynchronous I/O, thread management, SCTP,
jails, multi-FIB support, and misc. POSIX interfaces such as
posix_fallocate(2) and posix_fadvise(2).
- On operating systems supporting Capsicum, auditreduce(1) and praudit(1) now
run sandboxed.
- Empty "flags" and "naflags" fields are now permitted in audit_control(5).
Many thanks to Christian Brueffer for producing the OpenBSM release and
importing/tagging it in the vendor branch. This release will allow improved
auditing of a range of new FreeBSD functionality, as well as non-traditional
events (e.g., fine-grained I/O auditing) not required by the Orange Book or
Common Criteria.

builtins: Select correct code fragments when compiling for Thumb1/Thum2/ARM ISA.
Summary:
Value of __ARM_ARCH_ISA_THUMB isn't based on the actual compilation
mode (-mthumb, -marm), it reflect's capability of given CPU.
Due to this:
- use __tbumb__ and __thumb2__ insteand of __ARM_ARCH_ISA_THUMB
- use '.thumb' directive consistently in all affected files
- decorate all thumb functions using
DEFINE_COMPILERRT_THUMB_FUNCTION()
---------
Note: This patch doesn't fix broken Thumb1 variant of __udivsi3 !

implemented in top(1), rather than relying on K&R prototypes, which can
cause problems on targets where there are multiple incompatible calling
conventions and the compiler requires argument information to select the
correct one.
(There's a bit more to do here, since it looks like top(1) also sometimes
provides prototypes for various curses functions rather than relying on
the header file...)

Simplify some code.
realloc() with a null pointer is equivalent to malloc, so we don't need
to handle the two cases independently.
Fixes#46
This should help with lang/beignet and other programs, which expect
__cxa_demangle(name, NULL, NULL, &status) to return zero in status.

This is a painful change, but it is needed. On the one hand, we avoid
modifying them, and this slows down some ideas, on the other hand we still
eventually modify them and tools like netstat(1) never work on next version of
FreeBSD. We maintain a ton of spares in them, and we already got some ifdef
hell at the end of tcpcb.
Details:
- Hide struct inpcb, struct tcpcb under _KERNEL || _WANT_FOO.
- Make struct xinpcb, struct xtcpcb pure API structures, not including
kernel structures inpcb and tcpcb inside. Export into these structures
the fields from inpcb and tcpcb that are known to be used, and put there
a ton of spare space.
- Make kernel and userland utilities compilable after these changes.
- Bump __FreeBSD_version.

Add a clock_nanosleep() syscall, as specified by POSIX.
Make nanosleep() a wrapper around it.
Attach the clock_nanosleep test from NetBSD. Adjust it for the
FreeBSD behavior of updating rmtp only when interrupted by a signal.
I believe this to be POSIX-compliant, since POSIX mentions the rmtp
parameter only in the paragraph about EINTR. This is also what
Linux does. (NetBSD updates rmtp unconditionally.)
Copy the whole nanosleep.2 man page from NetBSD because it is complete
and closely resembles the POSIX description. Edit, polish, and reword it
a bit, being sure to keep any relevant text from the FreeBSD page.

We should never end up executing the inter-function padding, so we
are better off faulting than silently carrying on to whatever function
happens to be next.
Note that LLD will soon do this by default (although it currently pads

This commit replaces calloc calls, which called calloc() as if it were
malloc() by allocating a multiple of objects as a sizeof multiplied by
the number of objects. The patch rectifies this by calling calloc() as
it was meant to be called.
This commit also replaces realloc() with reallocarray() in a similar
fashion as above. Instead of calculating the memory to reallocated
(changed) by multiplying sizeof by the number of objects, the sizeof
and number are passed as separate arguments to reallocarray(), letting
reallocarray() do the multiplication instead. Like the calloc()
adjustment above, this is approach is cleaner and more elegant than
than the previous code.
This has been tested on my production firewall and a laptop (also
running ipfilter).

issues (non-functional __udivsi3 for example) with ARM specific instrict

disable all thumb[1][2] related feature.
I overlooked the fact that these manpages had been removed upstream
and replaced with their non *-api(3) equivalents. Follow upstream's

[SCEV] Decrease the recursion threshold for CompareValueComplexity
Fixes PR32142.
r287232 accidentally increased the recursion threshold for
CompareValueComplexity from 2 to 32. This change reverses that
change by introducing a separate flag for CompareValueComplexity's
threshold.
The latter revision fixes the excessive compile times for skein_block.c.
ATF_TP_ADD_TC should use `tp` as the second argument, not `tcs`, as
ATF_TP_ADD_TCS uses `tp` as its first argument.
