For buildworld orchestration, just prebuild libregex if GOOGLETEST is
enabled. googletest will get built in a later pass.
libregex is incomplete, but it's a bit less buggy than the in-base
libgnuregex and mostly OK.
While here, rename -DIWTH_GNU -> -DWITH_GNU_COMPAT; the option implies
that we're compatible with the GNU counterpart, not that we're including GNU
anything.
gtest tests want to use \w ([[:alnum:]]) at the very least, which was
causing them to fail after r363679.
Start linking against libregex so that this shorthand is implemented.
PR: 248452
The entire patch-set is not yet mature enough for commit, but this usable
subset is generally enough for googletest to be happy with and mostly map to
some existing concepts, so they're not as invasive.
The specific changes included here are:
- Branching in BREs with \|
- \w and \W for [[:alnum:]] and [^[:alnum:]] respectively
- \s and \S for [[:space:]] and [^[:space:]] respectively
- Additional quantifiers in BREs, \? and \+ (self-explanatory)
There's some #ifdef'd out work for allowing empty branches as a match-all.
This is a feature that's under assessment... future work will determine
how standard this behavior is and act accordingly.
The constant seems to exists on MacOS X >= 10.8.

The tests compare the command output (including of error cases) with the
expected output and exit code.
Not all tests are executed, since some expect to have a known good bc and
dc binary installed and compare results of large amounts of generated data
being processed by both versions to test for regressions.
This version omits the printing of a copyright header in interactive mode
and the dc command now exits after execution of the commands passed via -e
or -f instead of switching to interactive mode. To pass further commands
via STDIN when dc has been invoked with -e or -f, add "-f -" to the
parameter list.

This version makes dc exit after processing all commands passed via -e or -f

to emulate the behavior of versionm 3.1.3 and earlier, if desired).
The version and copyright message are no longer printed for interactive
sessions as was the case with the prior implementation in the FreeBSD base
system.

We bootstrap this file to allow compiling FreeBSD on Linux systems since
some boostrap tools use setmode(). Unfortunately, glibc's sys/stat.h
declares a non-static getumask() function (which is unimplemented!) and
that conflicts with the local getumask() function. To work around this
simply use a different name here.

GCC's cpp was exiting immediately when it failed to find requested
includes (<ncurses_cfg.h> and <ncurses_defs.h>). clang-cpp emitted an
error for the missing header files but continued processing the file
(thus not honoring any macros defined in the missing headers).
Arguably, the awk script is buggy since it doesn't check the return

Reduce code duplication when a bus is subclassed from simplebus by allowing

RISC-V doesn't support floating-point exceptions.
RISC-V Instruction Set Manual: Volume I: User-Level ISA, 11.2 Floating-Point
Control and Status Register: "As allowed by the standard, we do not support
traps on floating-point exceptions in the base ISA, but instead require
explicit checks of the flags in software. We considered adding branches
controlled directly by the contents of the floating-point accrued exception
flags, but ultimately chose to omit these instructions to keep the ISA simple."
We still need these functions, because some applications (notably Perl) call
them, but we cannot provide a meaningful implementation.

Currently the CONS_HISTORY and CONS_CLRHIST ioctls modify the state of the
active terminal instead of the terminal against which the ioctl was issued.
Because of the way vidcontrol(1) works, these are the same in most cases.
But a poorly-timed window switch can make them differ. This is reproducible
by issuing e.g. 'vidcontrol -s 2 && vidcontrol -C' to switch from vty 1 to
vty 2; teken will reset the cursor position on vty 1 but vt(4) will clear
the history buffer of vty 2, producing an interesting state of affairs.

The mvneta device requires MVNETA_TX_CMD_L4_CHECKSUM_NONE bit to be set in the tx descriptor is checksum not required. However, mvneta_tx_set_csumflag() is not setting this flag currently, causing the hardware to randomly corrupt IP header during transmission.
This affects injected IPv4 packets that skips kernel IP stack processing (e.g. DHCP), as well as all IPv6 packets, since the driver currently does not offload csum for IPv6.
The fix is to remove all the early return paths from mvneta_tx_set_csumflag() which do not set the MVNETA_TX_CMD_L4_CHECKSUM_NONE flag.

and getxattr operations.
This patch optionally enables generation of read, readlink and getxattr replies
in ext_pgs mbufs. Since neither of ND_EXTPG or ND_TLS are currently ever set,
there is no change in semantics at this time.
It also corrects the message in a couple of panic()s that should never occur.
This is another in the series of commits that add support to the NFS client
and server for building RPC messages in ext_pgs mbufs with anonymous pages.
This is useful so that the entire mbuf list does not need to be
copied before calling sosend() when NFS over TLS is enabled.
Use of ext_pgs mbufs will not be enabled until the kernel RPC is updated
to handle TLS.
