mycroft e8f7fd90c1 Actually, punt the `library' keyword; it does the same thing as `object',
and we really only need one of them.

mycroft 7d58ce9471 Add `object' and `library' keywords to pull in precompiled .o and .a files.
Syntax is like the `file' keyword; e.g.:
object	arch/i386/i386/mumble.o		[mumble] [needs-flag]
Largely from Michael Richardson in PR 3833, with some changes by me.

thorpej 9fec93804a Changes to config(8) to support dump configuration in the wake of the
new swap system.  The dump specification syntax is now more flexible,
and supports constructs like the following:

config netbsd root on ? type ? dumps on ?
	- wildcarded root, fstype, and dump device

config netbsd root on ? type ffs dumps on sd0b
	- wildcarded root, ffs root fs, always dump on sd0b

config netbsd root on de0 type nfs dumps on wd0b
	- mount an nfs root using de0, and write kernel crash dumps
	  to wd0b

Also, garbage-collect some now unused code, now that swap configuration
is no longer handled by config(8).

thorpej 267e8357fc Implement an unfortunate, and temporary, kludge to address the problem
reported in PR #3668 from maximum entropy <entropy@tanstaafl.bernstein.com>.

The problem: The unit number is not being conveyed to the configuration
crosscheck with root is a network interface; the device number is set
to NODEV, which sets up the (correct) defaults for swap/dump devices.
We can't change NODEV to a unit number, as the PR's patch suggests, as
this breaks the swap/dump defaults.  Rewriting that code is not really
justified, since it's soon to be obsoleted.

The kludge: add an "nv_ifunit" member to struct nvlist, which convey's
a network interface's unit number to the crosscheck routine.  It's not
pretty, but it's not terribly invasive, and can be garbage-collected
easily when the swap/dump goo is obsoleted.

1997-02-03 21:18:21 +00:00
thorpej e14a0d029f Add support for generating "option headers". These allow options to
be included in object dependencies.  config(8) is told to generate
a header for a particular option with the new "defopt" keyword, used
in the files.* system description files.  Options that are placed in
header files are not given -D... cpp flags.

This approach allows options to be turned into headers incrementally,
rather than all at once, and allows for non-header options, as well.

thorpej 07c71aa7f7 Implement new grammar and semantics for specifying file systems
and the root device:

- New "file-system" keyword is used to configure file systems into
  the kernel.
- New way of specifying root device, which allows root file system
  type to always be specified.  Examples:

	config gennetbsd swap generic
	config sdnetbsd root on sd0a swap on sd0b
	config nfsnetbsd root on nfs

  are replaced by:

	config gennetbsd root on ? type ?
	config sdnetbsd root on sd0a type ffs swap on sd0b
	config nfsnetbsd root on ? type nfs
	config lenetbsd root on le0 type nfs

  Note that specific network interfaces may now be specified as
  the root device.
- swapgeneric.c is no longer used; generate a swap*.c file for each
  "config" line in the kernel configuration file.

gwr 7fa1418031 Fix the bug I introduced in the last commit, which broke line contuation

gwr a0b75afc0b * Eliminate all shift/reduce conflicts in the grammar. This
requires that some ordering requirements are checked by the
  back-end C code instead of the parser (dirspecs, maxpart).

* Be more careful to require newline tokens in the grammer where
  they are expected, and deal with blank lines, etc.  This allows
  elimination of a trailing context on newline in the scanner.

* Let the parser set values for "needs-count" and "needs-flag"
  instead of making those special cases in the scanner.

* Get rid of '= ' preceeding actions (obsolete yacc syntax)

* Make the scanner not insert an extra newline after includes.
  (It was just an accidental side-effect of the ENDFILE stuff.)

cgd 2dd7a7984c Fix PR 2218. As noted (both in mail from me included in the PR, and
in XXX-marked comments in the recent attachment changes), this was a
long-standing bug in config.

The problem: If a device is attached to a device via an attribute exported
by that device (i.e. foo* at bar0, where 'bar' exports an attribute that
'foo' attaches to), but the device attached to is not present in the
kernel configuration file, AND another device which exports an attribute
that 'foo' attaches to _is_ present (e.g. a device baz0, if one could
specify 'foo0 at baz0'), then: the configuration file will (incorrectly)
be accepted by config, and the resulting ioconf.c will include a bogus
cfdata entry for the device (in the example, 'foo*').  This typically
causes the resulting kernel to crash during autoconfiguration.

The solution: Be much more careful about keeping track of where a device
was attached, and, in particular, if a device was attached to another device,
_always_ keep track of what device it was attached to.  Then, when
cross-checking, if the attached-to device isn't present, give up and do not
check attributes.  Also, document the process much more thoroughly.

cgd 95f205f10c fix bogon in device attachment name checking. the same rules should be
used for checking device attachment names as are used for device name
checking, because device names can be used as attachment names.  (Actually,
less strict rules could be used, but there's little point in that.)  This
was not a mistake of design, this was just a mistake; i misunderstood
the devbase name checking code.

1996-03-17 05:19:33 +00:00
cgd dfbb6d0884 fix a bug where definitions to be placed in headers wouldn't be
right/consistent.  If you had something like:

file	file.c		foo bar baz needs-flag

and any one of foo, bar, or baz caused it to be brought into the compile,
in the header you'd end up with:

#define NFOO	1
#define NBAR	1
#define NBAZ	1

even if only one of them were selected.  Other headers might have had a
different (inconsistent) set of definitions, depending on whether any of
their components were included, and any files necessary for the unspecified
options would not actually be present in the Makefile files list.  The
correct behaviour for the example above if only 'foo' is selected by
the config file is:

#define NFOO	1
#define NBAR	0
#define NBAZ	0

which is what config now does.  This bug has been present for a while.
(I don't know for sure that it was present in 4.4-Lite2, but from looking
at the Lite2 config sources, it appears to be there.)

lists to not have a newline properly emitted.  (It was emitting a

line position was 7 was right after the initial variable assignment
string (e.g. "OBJS=\t") was printed.)
