ghudson e312e1563e Don't canonicalize relative paths to the source tree any more; libkern
and libcompat can handle them as long as they begin with '.'.  If a
relative path doesn't begin with '.', add a "./" before it.

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 cb40dc44d0 two devices instances which are otherwise the same but do not attach
via the same attributes are _not_ the same, and should not be treated
as aliases of each other.

cgd 315f091f18 fix (apparently long-standing) bug which prevented devices from attaching
to interface attributes on a device other than the interface attribute that
the device was named the same as, if that one was there.

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 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 9c4f9d2daa spaces vs. tabs, spaces/tabs at EOL bogons. 1996-03-17 06:29:19 +00:00
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.

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.)

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.)

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.

cgd 7d351bb3f4 fix thinkos in emitobjs() and emitfiles() that would cause empty files
lists to not have a newline properly emitted.  (It was emitting a
newline only if the line position was != 7.  However, the only time the
line position was 7 was right after the initial variable assignment
string (e.g. "OBJS=\t") was printed.)

is different than the "machinename" internal variable, read

create a ${machinearch} sylink (or directory) pointing to the machinearch
include files (or containing them).
