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 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.)

mycroft 8441b8f88d Remove interrupt vector handling. This is done dynamically by all ports now. 1996-08-31 21:15:05 +00:00
mycroft ab6ebadde6 Add `source' and `build' directives, and corresponding options, per discussion
on tech-kern.  (See man page.)  Implementation by Greg Hudson.
Also, remove special case for i386 in vector handling, although this code isn't
actually used any more.

cgd 3ac7667c57 add BSDI-style expression support to optional file specifiers. Code mostly
taken from the parts of BSDI's 'config' which are freely-distributable
(under the LBL/UC Regents license), and adjusted to fit into our version.

cgd 9c70ac56a8 fix another just-discovered long-standing bug: foo0 at bar* is not legal
syntax.  (devices which specify 'at' can't be starred.  they can be
wildcarded, with ?, but not starred.)

thorpej cb6211e540 New device attachment scheme:
- split softc size and match/attach out from cfdriver into
	  a new struct cfattach.

	- new "attach" directive for files.*.  May specify the name of
	  the cfattach structure, so that devices may be easily attached
	  to parents with different autoconfiguration semantics.
