* Small steps towards ANSI VALUES type specifier:
** removed checks for VALUES-TYPE-{KEYP,KEYWORDS};
** &OPTIONAL type in VALUES does not automatically allow NIL;
** object type <type> in a values context \approx (VALUES &OPTIONAL
<type> &REST T); DEFKNOWN uses the old meaning;

* added type checking for single value and MV-BIND receivers;
* THE coerces the asserted type to VALUES;
* fixed order of CAST LTN-annotating;

* in VALUES types &OPTIONAL arguments are merged into &REST;
* (VALUES &REST T) => *;
* ENABLE-INTERRUPT accepts/returns C handler addresses as
FIXNUMs as suggested by CSR;
* added IR2 type checking.

This is an EXPERIMENTAL branch. Mayor change is reimplementation of
type assertions with CAST nodes, which should provide a way to fix
several classical bugs in the type checking system.

This version is a first try on the idea. It may be buggy, slow and
produce inefficient code.

Some easy fixes:
... SYMBOL-FUNCTION returns a function in our implementation
(Robert E. Brown sbcl-devel 2003-02-06)
... READ-DELIMITED-LIST returns a list
(Tony Martinez sbcl-devel 2003-02-09)
... make src/cold/chill.lisp loadable from anywhere
(Rudi Schlatte sbcl-devel 2003-02-09)
Also frob NEWS: put exciting things such as incompatible changes
and new contrib at the top of the section.

Yet another incremental extension to the type system algorithms.
In the presence of types such as (MEMBER 1 "foo" (X)), we
cannot hash VALUES-SPECIFIER-TYPE on EQUAL, because two
such types can contain the same or different (under EQL)
"foo" or (X), and yet be the same under EQUALity. So
... define a new function EQUAL-BUT-NO-CAR-RECURSION, which is
almost but not quite what it sounds (it tests strings
bit-vectors and lists by EQL, not EQUAL);
... use it as the new test function for the
The presence of numeric types in NOT types can be problematic,
as Paul Dietz' test of (OR BIGNUM FIXNUM) showed. So
... work a lot harder in the NOT type translator, to bring
numeric types out: we treat (NOT (INTEGER a b)) as
(OR (NOT INTEGER) (INTEGER * a) (INTEGER b *)), with the
obvious generalizations.
Now (AND INTEGER (NOT FIXNUM)) parses as
which is right, but no longer an intersection type, so
... move BIGNUM unparsing from INTERSECTION-TYPE to UNION-TYPE.
Even with all this, we don't get (OR INTEGER RATIO) right, so
... teach the type system some more set theory, with new
HAIRY-TYPE and INTERSECTION union methods.
(and all the people rejoiced!)

Update asdf to newer upstream version (:serial t)

module-provide-asdf now refuses to try providing a module
unless it can find a system file, so doesn't usurp the whole
PROVIDE/REQUIRE mechanism for non-asdf modules.

make-target-contrib.sh should set SBCL_HOME to the source
tree, so that inter-module dependencies are searched for in
the right place

Actually add the ACL repl to the repository this time

Changes to PROVIDE/REQUIRE to make them (a) conform to ANSI,
(b) any use...
... cease nonstandardly downcasing elements in *MODULES*
... add a list of *MODULE-PROVIDER-FUNCTIONS* which the user
can hang functions off to make REQUIRE do whatever he
wants it to do.
... its default member knows how to load files in

First pass at a contrib infrastructure...
... change install.sh to do new and exciting things, and as a
side benefit, able to install other than into /usr/local
... amend INSTALL instructions to match

Two contrib modules...
... asdf here is a direct copy of the one in cclan, but
despite being portable and therefore not really
qualifying, will be v. useful for loading the others
... bsd-sockets (db-sockets by any other name) is a fairly
low-level interface to the BSD socket API: high-level
interfaces (e.g. ACL-compatible, or CLOCC PORT) could be
built on top of it without getting dirty with ALIEN

... make the intersection of negation types with non-hairy types
smarter, by considering the type relationship of the
negation (e.g. (AND BASE-CHAR (NOT BASE-CHAR)) and

then the whole type must be NIL too.
