Support full Common Lisp multiple values in C.
lisp/ChangeLog
2009-08-11 Aidan Kehoe <kehoea@parhasard.net>
* bytecomp.el :
Update this file to support full C-level multiple values. This
involves:
-- Four new bytecodes, and special compiler functions to compile
multiple-value-call, multiple-value-list-internal, values,
values-list, and, since it now needs to pass back multiple values
and is a special form, throw.
-- There's a new compiler variable, byte-compile-checks-on-load,
which is a list of forms that are evaluated at the very start of a
file, with an error thrown if any of them give nil.
-- The header is now inserted *after* compilation, giving a chance
for the compilation process to influence what those checks
are. There is still a check done before compilation for non-ASCII
characters, to try to turn off dynamic docstrings if appopriate,
in `byte-compile-maybe-reset-coding'.
Space is reserved for checks; comments describing the version of
the byte compiler generating the file are inserted if space
remains for them.
* bytecomp.el (byte-compile-version):
Update this, we're a newer version of the byte compiler.
* byte-optimize.el (byte-optimize-funcall):
Correct a comment.
* bytecomp.el (byte-compile-lapcode):
Discard the arg with byte-multiple-value-call.
* bytecomp.el (byte-compile-checks-and-comments-space):
New variable, describe how many octets to reserve for checks at
the start of byte-compiled files.
* cl-compat.el:
Remove the fake multiple-value implementation. Have the functions
that use it use the real multiple-value implementation instead.
* cl-macs.el (cl-block-wrapper, cl-block-throw):
Revise the byte-compile properties of these symbols to work now
we've made throw into a special form; keep the byte-compile
properties as anonymous lambdas, since we don't have docstrings
for them.
* cl-macs.el (multiple-value-bind, multiple-value-setq)
(multiple-value-list, nth-value):
Update these functions to work with the C support for multiple
values.
* cl-macs.el (values):
Modify the setf handler for this to call
#'multiple-value-list-internal appropriately.
* cl-macs.el (cl-setf-do-store):
If the store form is a cons, treat it specially as wrapping the
store value.
* cl.el (cl-block-wrapper):
Make this an alias of #'and, not #'identity, since it needs to
pass back multiple values.
* cl.el (multiple-value-apply):
We no longer support this, mark it obsolete.
* lisp-mode.el (eval-interactive-verbose):
Remove a useless space in the docstring.
* lisp-mode.el (eval-interactive):
Update this function and its docstring. It now passes back a list,
basically wrapping any eval calls with multiple-value-list. This
allows multiple values to be printed by default in *scratch*.
* lisp-mode.el (prin1-list-as-multiple-values):
New function, printing a list as multiple values in the manner of
Bruno Haible's clisp, separating each entry with " ;\n".
* lisp-mode.el (eval-last-sexp):
Call #'prin1-list-as-multiple-values on the return value of
#'eval-interactive.
* lisp-mode.el (eval-defun):
Call #'prin1-list-as-multiple-values on the return value of
#'eval-interactive.
* mouse.el (mouse-eval-sexp):
Deal with lists corresponding to multiple values from
#'eval-interactive. Call #'cl-prettyprint, which is always
available, instead of sometimes calling #'pprint and sometimes
falling back to prin1.
* obsolete.el (obsolete-throw):
New function, called from eval.c when #'funcall encounters an
attempt to call #'throw (now a special form) as a function. Only
needed for compatibility with 21.4 byte-code.
man/ChangeLog addition:
2009-08-11 Aidan Kehoe <kehoea@parhasard.net>
* cl.texi (Organization):
Remove references to the obsolete multiple-value emulating code.
src/ChangeLog addition:
2009-08-11 Aidan Kehoe <kehoea@parhasard.net>
* bytecode.c (enum Opcode /* Byte codes */):

(TOP): Modify this macro to ignore multiple values.
(TOP_LVALUE): New macro.

anything.
(Bbind_multiple_value_limits, Bmultiple_value_call,
Bmultiple_value_list_internal, Bthrow): Implement the new
bytecodes.
(Bgotoifnilelsepop, Bgotoifnonnilelsepop, BRgotoifnilelsepop,
BRgotoifnonnilelsepop):
Discard any multiple values.

* macros.c (pop_kbd_macro_event):

special form.
* eval.c:
Make Qthrow, Qobsolete_throw available as symbols.
Provide multiple_value_current_limit, multiple-values-limit (the
latter as specified by Common Lisp.
* eval.c (For):
Ignore multiple values when comparing with Qnil, but pass any
multiple values back for the last arg.
* eval.c (Fand):
Ditto.
* eval.c (Fif):
Ignore multiple values when examining the result of the
condition.
* eval.c (Fcond):
Ignore multiple values when comparing what the clauses give, but
pass them back if a clause gave non-nil.
* eval.c (Fprog2):
Never pass back multiple values.
* eval.c (FletX, Flet):
Ignore multiple when evaluating what exactly symbols should be
bound to.
* eval.c (Fwhile):
Ignore multiple values when evaluating the test.
* eval.c (Fsetq, Fdefvar, Fdefconst):
Ignore multiple values.
* eval.c (Fthrow):
Declare this as a special form; ignore multiple values for TAG,
preserve them for VALUE.
* eval.c (throw_or_bomb_out):
Make this available to other files, now Fthrow is a special form.
* eval.c (Feval):
Ignore multiple values when calling a compiled function, a
non-special-form subr, or a lambda expression.
* eval.c (Ffuncall):
If we attempt to call #'throw (now a special form) as a function,
don't error, call #'obsolete-throw instead.
* eval.c (make_multiple_value, multiple_value_aset)
(multiple_value_aref, print_multiple_value, mark_multiple_value)
(size_multiple_value):
Implement the multiple_value type. Add a long comment describing
our implementation.
