Add compiler macros and compilation sanity-checks for functions with keywords.
2010-10-25 Aidan Kehoe <kehoea@parhasard.net>
Add compiler macros and compilation sanity-checking for various
functions that take keywords.
* byte-optimize.el (side-effect-free-fns): #'symbol-value is
side-effect free and not error free.
* bytecomp.el (byte-compile-normal-call): Check keyword argument
lists for sanity; store information about the positions where
keyword arguments start using the new byte-compile-keyword-start
property.
* cl-macs.el (cl-const-expr-val): Take a new optional argument,
cl-not-constant, defaulting to nil, in this function; return it if
the expression is not constant.
(cl-non-fixnum-number-p): Make this into a separate function, we
want to pass it to #'every.
(eql): Use it.
(define-star-compiler-macros): Use the same code to generate the
member*, assoc* and rassoc* compiler macros; special-case some
code in #'add-to-list in subr.el.
(remove, remq): Add compiler macros for these two functions, in
preparation for #'remove being in C.
(define-foo-if-compiler-macros): Transform (remove-if-not ...) calls to
(remove ... :if-not) at compile time, which will be a real win
once the latter is in C.
(define-substitute-if-compiler-macros)
(define-subst-if-compiler-macros): Similarly for these functions.
(delete-duplicates): Change this compiler macro to use
#'plists-equal; if we don't have information about the type of
SEQUENCE at compile time, don't bother attempting to inline the
call, the function will be in C soon enough.
(equalp): Remove an old commented-out compiler macro for this, if
we want to see it it's in version control.
(subst-char-in-string): Transform this to a call to nsubstitute or
nsubstitute, if that is appropriate.
* cl.el (ldiff): Don't call setf here, this makes for a load-time
dependency problem in cl-macs.el

22 Commentary: |
1231 | 23 |
24 Compile this file. Run it in the background giving it a command line | |
25 argument PORT which is a positive integer 1024 < PORT < 32768 (avoid the | |
26 numbers assigned in /etc/services). | |
27 | |
28 Then start up a fresh (you're going to crash) XEmacs. Execute the following | |
29 | |
30 (defun lose (port) | |
31 (interactive "nUrk: ") | |
32 (require 'comint) | |
33 (while t | |
34 (condition-case e | |
35 (let* ((name "*lose*") | |
36 (b (get-buffer-create name))) | |
37 (switch-to-buffer b) | |
38 (comint-mode) | |
39 (comint-exec b name (cons "127.0.0.1" port) nil '()) | |
40 (process-send-string (get-buffer-process b) "\377\373\001") | |
41 (process-send-string (get-buffer-process b) "\377\373\001")) | |
42 (error (message "URK: %s" e)) (sit-for 1)))) | |
43 | |
44 Then M-x lose RET PORT RET and you lose big (in XEmacs 21.1, anyway). | |
45 Note: the error messages are proper functioning. What should eventually | |
46 happen after a number of SIGPIPEs is that you get a SIGSEGV and life is | |
47 bad and XEmacs is dead. | |
