unset on unload), similarily to what i386/machdep.c does #ifdef
COMPAT_SVR4. This makes the svr4 LKM actually work on i386.
XXX kind of ugly, but doing this more generic way would be overkill
restore %fs/%gs appropriately.
Fixes kern/14275 - compat svr4 works on i386 again :)
Thanks to MOCHIDA Shuji for initial investigation on the issue, that helped
to find the bug a lot.

_KERNEL or _STANDALONE and <inttypes.h> otherwise, and use standard
inttype types.

using `uname -s`-`uname -r`-`uname -p || uname -m`. This can be overridden
in mk.conf or the environment, and is used by host tools to ensure that
build hosts do not clobber each other.
* Now that there's an objdir in src/tools, make a default TOOLDIR by creating
"tools.${HOST_OSTYPE}" in the objdir (if it exists) of src/tools. This
means that TOOLDIR is no longer required to be set in a build, though it
still may be set manually if desired.
* Set MKTOOLS to "yes" by default, since the default TOOLDIR is now located
in a known mutable location. This may still be set manually if desired.
defined, as <bsd.own.mk> always sets it; also, compare only against "yes"
(not "no") for a yes/no check, as there are two negative states ("no" and
"never").
* Don't return if wait()ing for the child is interrupted.
* Fix a race condition for the parent's SIG{INT,QUIT} disposition.
* While we're here, convert from using signal(3) to sigaction(2).
* Replace chdir_verify_path() with Main_SetObjdir(), which can be called
externally, and can take a "const char *". (There's a lot of non-const
"char *" passing around in var.c of what should be const strings....)
* Rewrite the initial "find my .OBJDIR" code to make use of the new
function. This still functions as it had in the past, but the comment
above this block was changed to reflect reality: if MAKEOBJDIRPREFIX
or MAKEOBJDIR are set in the environment, then *only that value* is
tried; make does not fall back to obj.MACHINE, obj, and /usr/obj/`pwd`
as it would without these env vars set.
* Add a new special target, .OBJDIR:, which when parsed will cause make to
change to a new object directory and reset .OBJDIR, and PWD in the
environment. This will allow some makefiles (mainly, src/tools)
to override the default objdir semantics in order to add custom logic.
quoting, so the commands were thought to be one big word with embedded
whitespace)
* New options:
-O obj Set root of an obj tree; sets MAKEOBJDIR to an appropriate
substitution pattern.
-o Sets MKOBJDIRS=no (otherwise sets MKOBJDIRS=yes)
-u Sets UPDATE
just don't build the tools if USETOOLS!=yes. This permits objdirs to
be created even when USETOOLS=no.
* Clean up use of "-m" by specifying it to .MAKEFLAGS: if needed.
(This splits out the "default system include paths" into its own Lst
variable, and uses it only if sysIncPath is empty. This allows sysIncPath
to be filled in by the Makefile itself.)
the system's byte-order:
- host to {big,little}-endian {16,32}
- {big,little}-endian {16,32} to host
These are not intended to be used in libsa directly, but are rather
intended to be used by host tools which may use libsa routines (such
as loadfile()) which need to use explicit byte-ordering.
* Don't require DESTDIR when -b is set.
* Add -n option, which prints the commands that would be run by build.sh,
but doesn't run them (much like make's -n option).
* Auto-resolve relative paths for -D, -R, and -T (but not for the
corresponding environment variables).
* Explicitly declare defaults of all shell variables used where feasible,
rather than sprinkling ${varname-value} expansions.
* Prefix shell true/false variables with "do_" to indicate their use as
actual values in shell expressions (like "$do_buildsystem && echo foo").

executable mappings. Stop overloading VTEXT for this purpose (VTEXT
also has another meaning).
- Rename vn_marktext() to vn_markexec(), and use it when executable
mappings of a vnode are established.
- In places where we want to set VTEXT, set it in v_flag directly, rather
than making a function call to do this (it no longer makes sense to
use a function call, since we no longer overload VTEXT with VEXECMAP's
meaning).
VEXECMAP suggested by Chuq Silvers.
