that uses each configuration parameter.
This will stop kernel objects build with different options (that come from
config files) being linked together or loaded as a LKM.
Currently some options that have an effect on the kernel DDI/KI are passed
directly as parameters to cc.
An aim (for anyone adequately bored) would be to reduce the number of these
constants that appear in each .o file. .o files with the same constants
should be sharable between kernels (even between XEN and i386).
configuration file (although it is meant to be used mostly with
std.${ARCH}), and prints out a configuration file that includes it and
select every single option and parameter, and define an instance for every
single possible attachment. IOW, selects everything, into a would-be
"LINT" config.
The resulting config really isn't meant to be runnable, but should be
somewhat buildable on most archs. It still needs adjustments because some
options are peculiar (e.g., ACPI_DSDT_FILE wants an existing file as its
value), so it's not yet possible to do "config -L; config; build" in an
automated way.
- Move documentation for "package", because as I learned tonight, it's not
allowed before setmachine. You get to discover scary new stuff about
config(1) each time you look at it.
It caused config(1) to crash on the following assert() if the list was used.
This bug shows up after the recent change in files.c which fixed a memory leak.

call - which makes the code completely impossibly to follow, call fflush()
and ferror() just prior to calling fclose().
This has the advantage of actually detecting the any write errors, since
the output is block bufferred and will typically not happen during fprintf()
but only during the fclose() - where it is difficult to report.
I also singlilarly refuse to add (void) casts to every printf call in the
system - since it almost never makes any sense to look at the return value
(unless you want to know how many bytes were actually writtem).
If a default is specified then the option is always defined in the
corresponding .h file.
Particularly useful for parameters where the default action isn't the
same a defining the value zero, given that the current use of #if defined(opt)
is open to problems wehere the relevant .h file isn't actually included, so
requiring an option to always have a value makes sense.
Also included (but commented out) is code that adds a global symbol to
the object file to stop objects compiled with different values for the
same option being linked together - I'm not quite happy with it yet!
does is cause confusion when I try to add default values for defparam.
Also if malloc()/free() aren't efficient enough for us, we ought to fix
them rather than having local free list - so kill the local free lists.
obsolete defflag <option> [, <option> [, ...]]
obsolete defparam <option> [, <option> [, ...]]
The two statements actually do the same thing (there could be only one),
but it makes things less cryptic that way. The optional ": deps" part of
a 'defflag' or 'defparam' still has to be dropped when it gets obsoleted.
When the user has 'options OBSOLETE_OPTION' in his configuration file, it
is ignored (that is, opt_*.h files are generated as if it wasn't there),
and the user gets a warning about it.
Bump version to 20060525.
When someone first uses that syntax in the tree, a "version 20060525"
statement should be added before its occurrence, preferably at the top
of sys/conf/files.
