Fix various small issues with the multiple-value implementation.
lisp/ChangeLog addition:
2009-08-31 Aidan Kehoe <kehoea@parhasard.net>
* byte-optimize.el (byte-optimize-form-code-walker):
Be careful about discarding multiple values when optimising
#'prog1 calls.
(byte-optimize-or):
Preserve any trailing nil, as this is a supported way to
explicitly discard multiple values.
(byte-optimize-cond-1):
Discard multiple values with a singleton followed by no more
clauses.
* bytecomp.el (progn):
(prog1):
(prog2):
Be careful about discarding multiple values in the byte-hunk
handler of these three forms.
* bytecomp.el (byte-compile-prog1, byte-compile-prog2):
Don't call #'values explicitly, use `(or ,(pop form) nil) instead,
since that compiles to bytecode, not a funcall.
* bytecomp.el (byte-compile-values):
With one non-const argument, byte-compile to `(or ,(second form)
nil), not an explicit #'values call.
* bytecomp.el (byte-compile-insert-header):
Be nicer in the error message to emacs versions that don't
understand our bytecode.
src/ChangeLog addition:
2009-08-31 Aidan Kehoe <kehoea@parhasard.net>
* eval.c (For, Fand):
Don't declare val as REGISTER in these functions, for some reason
it breaks the non-DEBUG union build. These functions are only
called from interpreted code, the performance implication doesn't
matter. Thank you Robert Delius Royar!
* eval.c (Fmultiple_value_list_internal):
Error on too many arguments.
tests/ChangeLog addition:
2009-08-31 Aidan Kehoe <kehoea@parhasard.net>
* automated/lisp-tests.el (Assert-rounding):
Remove an overly-verbose failure message here.
Correct a couple of tests which were buggy in themselves. Add
three new tests, checking the behaviour of #'or and #'and when
passed zero arguments, and a Known-Bug-Expect-Failure call
involving letf and values. (The bug predates the C-level
multiple-value implementation.)
