quantum bytewise to the address of a 64-bit variable results in writing
to the "wrong" 32-bit half so adjust the address accordingly. This fix
is implemented in a hackish way for two reasons:
o in order to be able to get it into 8.3 with zero impact on the little-
endian architectures where this bug has no effect and
o to avoid blowing the x86 boot2 out of the water again when compiling
it with clang, which all sane versions of this fix tested do.
This change fixes booting from UFS1 file systems on big-endian machines.

Winbond Super I/O chips.
With minor efforts it should be possible the extend the driver to support
further chips/revisions available from Winbond. In the simplest case
only new IDs need to be added, while different chipsets might require
their own function to enter extended function mode, etc.

it's value is change to be an empty string after the initial call to
parse, and cmd[]'s value can be changed (thus losing a prior setting for
kname) due to user input at the boot prompt. While here, ensure that that
initial boot config file text is nul-terminated, that ops is initialized
to zero, and that kname is always initialized to a valid string.

get rid of testing explicitly for clang (using ${CC:T:Mclang}) in
individual Makefiles.
Instead, use the following extra macros, for use with clang:
- NO_WERROR.clang (disables -Werror)
- NO_WCAST_ALIGN.clang (disables -Wcast-align)
- NO_WFORMAT.clang (disables -Wformat and friends)
- CLANG_NO_IAS (disables integrated assembler)
- CLANG_OPT_SMALL (adds flags for extra small size optimizations)
As a side effect, this enables setting CC/CXX/CPP in src.conf instead of
make.conf! For clang, use the following:
CC=clang
CXX=clang++
CPP=clang-cpp

- Use dots to provide a line to visually connect the menu
selections with their values
- Replace Enabled/Disabled with off/On

- Remove confusing "Boot" from selections that don't boot.
- With loader_color=1 in /boot/loader.conf, use reverse video to
highlight enabled options

from the interactive loader(8) prompt and beastie_disable="YES" is set
in loader.conf(5). In this case menu.rc is not evaluated and consequently
menu-unset does not have a body yet. This results in the ficl warning
"menu-unset not found" when try-menu-unset invokes menu-unset.
Check for beastie_disable="YES" explicitly, so that the try-menu-unset
word will not attempt to invoke menu-unset because the menu will have
never been configured. [1]
Use the sfind primitive as a last resort as an additional safer approach
conjuring a foreign word safely. [2]

'comconsole_pcidev'. The former allows to set the base address of the
serial console i/o port. The later takes the string of the format
'bus:device:function:[bar]' as a value and uses the serial port attached
as PCI device at the specified location for console.
Both variants pass 'hw.uart.console' variable to the uart driver to
properly hand-over the kernel console.
Change allows to use ISA serial ports other than COM1 for the
loader/kernel console without loader recompilation. Also, you can use
PCI-attached port as the console, e.g. Intel AMT serial pseudo-port on
some motherboards based on Q67 chipset.

The index() and rindex() functions were marked LEGACY in the 2001
revision of POSIX and were subsequently removed from the 2008 revision.
The strchr() and strrchr() functions are part of the C standard.
This makes the source code a lot more consistent, as most of these C
files also call into other str*() routines. In fact, about a dozen
already perform strchr() calls.
As I looked through the C library, I noticed the FreeBSD MIPS port has a
hand-written version of index(). This is nice, if it weren't for the
fact that most applications call strchr() instead.
Also, on the other architectures index() and strchr() are identical,
meaning we have two identical pieces of code in the C library and
statically linked applications.
Solve this by naming the actual file strchr.[cS] and let it use
__strong_reference()/STRONG_ALIAS() to provide the index() routine. Do
the same for rindex()/strrchr().
This seems to make the C libraries and static binaries slightly smaller,
but this reduction in size seems negligible.
before invoking the kernel.
Quoting submitter:
The issue is with the new boot loader menu. It adds many loader variables
including ones that contain ANSI color escapes.
Obviously, these ANSI codes don't play well with serial consoles when
kenv(1) is executed without arguments (reports vary as to what happens,
but it's never pretty).
The net-effect is that kenv(1) no longer reports menu-related variables.
In essence, kenv(1) output should now appear the same as on RELENG_8
(which lacks the new boot loader and didn't use any such variables).
Thus, restoring serial console glory.
