annotate lisp/bytecomp.el @ 4995:8431b52e43b1
Move the various map* functions to C; add #'map-into.
src/ChangeLog addition:
2010-01-31 Aidan Kehoe <kehoea@parhasard.net>
Move #'mapcar*, #'mapcan, #'mapc, #'map, #'mapl, #'mapcon to C;
extend #'mapvector, #'mapconcat, #'mapcar to support more
SEQUENCES; have them all error with circular lists.
* fns.c (Fsubseq): Call CHECK_SEQUENCE here; Flength can return
from the debugger if it errors with a non-sequence, leading to a
crash in Fsubseq if sequence really is *not* a sequence.
(mapcarX): Rename mapcar1 to mapcarX; rework it comprehensively to
take an optional lisp output argument, and a varying number of
sequences.
Special-case a single list argument, as we used to, saving its
elements in the stack space for the results before calling
FUNCTION, so FUNCTION can corrupt the list all it
wants. dead_wrong_type_argument() in the other cases if we
encounter a non-cons where we expected a cons.
(Fmapconcat):
Accept further SEQUENCES after separator here. Special-case
the idiom (mapconcat 'identity SEQUENCE), don't even funcall.
(FmapcarX): Rename this from Fmapcar. Accept optional SEQUENCES.
(Fmapvector): Accept optional SEQUENCES.
(Fmapcan, Fmapc, Fmap): Move these here from cl-extra.el.
(Fmap_into): New function, as specified by Common Lisp.
(maplist): New function, the guts of the implementation of
Fmaplist and Fmapl.
(Fmaplist, Fmapl, Fmapcon): Move these from cl-extra.el.
(syms_of_fns):
Add a few needed symbols here, for the type tests
used by #'map. Add the new subrs, with aliases for #'mapc-internal
and #'mapcar.
* general-slots.h: Declare Qcoerce here, now it's used in both
indent.c and fns.c
* indent.c (syms_of_indent): Qcoerce is gone from here.
* lisp.h: Add ARRAYP(), SEQUENCEP(), and the corresponding CHECK_*
macros. Declare Fbit_vector, Fstring, FmapcarX, now other files
need to use them.
* data.c (Farrayp, Fsequencep): Use ARRAYP and SEQUENCEP, just
added to lisp.h
* buffer.c (Fbuffer_list): Now Fmapcar has been renamed FmapcarX
and takes MANY arguments, update this function to reflect that.
lisp/ChangeLog addition:
2010-01-31 Aidan Kehoe <kehoea@parhasard.net>
* cl.el (mapcar*): Delete; this is now in fns.c.
Use #'mapc, not #'mapc-internal in a couple of places.
* cl-macs.el (mapc, mapcar*, map): Delete these compiler macros
now the corresponding functions are in fns.c; there's no run-time
advantage to the macros.
* cl-extra.el (coerce): Extend the possible conversions here a
little; it's not remotely comprehensive yet, though it does allow
running slightly more Common Lisp code than previously.
(cl-mapcar-many): Delete.
(map, maplist, mapc, mapl, mapcan, mapcon): Move these to fns.c.
* bytecomp.el (byte-compile-maybe-mapc):
Use #'mapc itself, not #'mapc-internal, now the former is in C.
(mapcar*): Use #'byte-compile-maybe-mapc as this function's
byte-compile method, now a #'mapc that can take more than one
sequence is in C.
* obsolete.el (cl-mapc): Move this compatibility alias to this file.
* update-elc.el (do-autoload-commands): Use #'mapc, not
#'mapc-internal here.

32 ;;; Synched up with: FSF 19.30. | |
33 | |
34 ;;; Commentary: | |
35 | |
36 ;; The Emacs Lisp byte compiler. This crunches lisp source into a | |
442 | 37 ;; sort of p-code (`bytecode') which takes up less space and can be |
38 ;; interpreted faster. First, the source code forms are converted to | |
39 ;; an intermediate form, `lapcode' [`LAP' == `Lisp Assembly Program'] | |
40 ;; which is much easier to manipulate than bytecode. Then the lapcode | |
41 ;; is converted to bytecode, which can be considered to be actual | |
42 ;; machine language. Optimizations can occur at either the source | |
43 ;; level or the lapcode level. | |
44 | |
45 ;; The user entry points are byte-compile-file, | |
428 | 46 ;; byte-recompile-directory and byte-compile-buffer. |
47 | |
48 ;;; Code: | |
49 | |
50 ;;; ======================================================================== | |
51 ;;; Entry points: | |
52 ;;; byte-recompile-directory, byte-compile-file, | |
53 ;;; batch-byte-compile, batch-byte-recompile-directory, | |
54 ;;; byte-compile, compile-defun, | |
55 ;;; display-call-tree | |
56 ;;; RMS says: | |
57 ;;; (byte-compile-buffer and byte-compile-and-load-file were turned off | |
58 ;;; because they are not terribly useful and get in the way of completion.) | |
59 ;;; But I'm leaving them. --ben | |
60 | |
61 ;;; This version of the byte compiler has the following improvements: | |
62 ;;; + optimization of compiled code: | |
63 ;;; - removal of unreachable code; | |
64 ;;; - removal of calls to side-effectless functions whose return-value | |
65 ;;; is unused; | |
66 ;;; - compile-time evaluation of safe constant forms, such as (consp nil) | |
67 ;;; and (ash 1 6); | |
68 ;;; - open-coding of literal lambdas; | |
69 ;;; - peephole optimization of emitted code; | |
70 ;;; - trivial functions are left uncompiled for speed. | |
71 ;;; + support for inline functions; | |
72 ;;; + compile-time evaluation of arbitrary expressions; | |
73 ;;; + compile-time warning messages for: | |
74 ;;; - functions being redefined with incompatible arglists; | |
75 ;;; - functions being redefined as macros, or vice-versa; | |
76 ;;; - functions or macros defined multiple times in the same file; | |
77 ;;; - functions being called with the incorrect number of arguments; | |
78 ;;; - functions being called which are not defined globally, in the | |
79 ;;; file, or as autoloads; | |
80 ;;; - assignment and reference of undeclared free variables; | |
81 ;;; - various syntax errors; | |
82 ;;; + correct compilation of nested defuns, defmacros, defvars and defsubsts; | |
83 ;;; + correct compilation of top-level uses of macros; | |
84 ;;; + the ability to generate a histogram of functions called. | |
85 | |
86 ;;; User customization variables: | |
87 ;;; | |
88 ;;; byte-compile-verbose Whether to report the function currently being | |
89 ;;; compiled in the minibuffer; | |
90 ;;; byte-optimize Whether to do optimizations; this may be | |
91 ;;; t, nil, 'source, or 'byte; | |
92 ;;; byte-optimize-log Whether to report (in excruciating detail) | |
93 ;;; exactly which optimizations have been made. | |
94 ;;; This may be t, nil, 'source, or 'byte; | |
95 ;;; byte-compile-error-on-warn Whether to stop compilation when a warning is | |
96 ;;; produced; | |
97 ;;; byte-compile-delete-errors Whether the optimizer may delete calls or | |
98 ;;; variable references that are side-effect-free | |
99 ;;; except that they may return an error. | |
100 ;;; byte-compile-generate-call-tree Whether to generate a histogram of | |
101 ;;; function calls. This can be useful for | |
102 ;;; finding unused functions, as well as simple | |
103 ;;; performance metering. | |

444 | 130 ;;; see also the function `byte-compile-dest-file'. |
428 | 131 ;;; byte-compile-overwrite-file If nil, delete old .elc files before saving. |
132 ;;; | |
133 ;;; Most of the above parameters can also be set on a file-by-file basis; see | |
134 ;;; the documentation of the `byte-compiler-options' macro. | |
135 | |
136 ;;; New Features: | |
137 ;;; | |
138 ;;; o The form `defsubst' is just like `defun', except that the function | |
139 ;;; generated will be open-coded in compiled code which uses it. This | |
140 ;;; means that no function call will be generated, it will simply be | |
141 ;;; spliced in. Lisp functions calls are very slow, so this can be a | |
142 ;;; big win. | |
143 ;;; | |
144 ;;; You can generally accomplish the same thing with `defmacro', but in | |
145 ;;; that case, the defined procedure can't be used as an argument to | |
146 ;;; mapcar, etc. | |
147 ;;; | |
148 ;;; o You can make a given function be inline even if it has already been | |
149 ;;; defined with `defun' by using the `proclaim-inline' form like so: | |
150 ;;; (proclaim-inline my-function) | |
151 ;;; This is, in fact, exactly what `defsubst' does. To make a function no | |
152 ;;; longer be inline, you must use `proclaim-notinline'. Beware that if | |
153 ;;; you define a function with `defsubst' and later redefine it with | |
444 | 154 ;;; `defun', it will still be open-coded until you use `proclaim-notinline'. |
428 | 155 ;;; |
156 ;;; o You can also open-code one particular call to a function without | |
157 ;;; open-coding all calls. Use the 'inline' form to do this, like so: | |
158 ;;; | |
159 ;;; (inline (foo 1 2 3)) ;; `foo' will be open-coded | |
160 ;;; or... | |
161 ;;; (inline ;; `foo' and `baz' will be | |
162 ;;; (foo 1 2 3 (bar 5)) ;; open-coded, but `bar' will not. | |
163 ;;; (baz 0)) | |
164 ;;; | |
165 ;;; o It is possible to open-code a function in the same file it is defined | |
166 ;;; in without having to load that file before compiling it. the | |
167 ;;; byte-compiler has been modified to remember function definitions in | |
168 ;;; the compilation environment in the same way that it remembers macro | |
169 ;;; definitions. | |
170 ;;; | |
171 ;;; o Forms like ((lambda ...) ...) are open-coded. | |
172 ;;; | |
444 | 173 ;;; o The form `eval-when-compile' is like `progn', except that the body |
428 | 174 ;;; is evaluated at compile-time. When it appears at top-level, this |
175 ;;; is analogous to the Common Lisp idiom (eval-when (compile) ...). | |
176 ;;; When it does not appear at top-level, it is similar to the | |
177 ;;; Common Lisp #. reader macro (but not in interpreted code). | |
178 ;;; | |
444 | 179 ;;; o The form `eval-and-compile' is similar to `eval-when-compile', |
180 ;;; but the whole form is evalled both at compile-time and at run-time. | |
428 | 181 ;;; |
182 ;;; o The command M-x byte-compile-and-load-file does what you'd think. | |
183 ;;; | |
444 | 184 ;;; o The command `compile-defun' is analogous to `eval-defun'. |
428 | 185 ;;; |
444 | 186 ;;; o If you run `byte-compile-file' on a filename which is visited in a |
428 | 187 ;;; buffer, and that buffer is modified, you are asked whether you want |
188 ;;; to save the buffer before compiling. | |
189 ;;; | |
190 ;;; o You can add this to /etc/magic to make file(1) recognize the files | |
191 ;;; generated by this compiler: | |
192 ;;; | |
613 | 193 ;;; 0 string ;ELC XEmacs Lisp compiled file, |
428 | 194 ;;; >4 byte x version %d |
195 ;;; | |
196 ;;; TO DO: | |
197 ;;; | |
198 ;;; o Should implement declarations and proclamations, notably special, | |
199 ;;; unspecial, and ignore. Do this in such a way as to not break cl.el. | |
200 ;;; o The bound-but-not-used warnings are not issued for variables whose | |
201 ;;; bindings were established in the arglist, due to the lack of an | |
202 ;;; ignore declaration. Once ignore exists, this should be turned on. | |
203 ;;; o Warn about functions and variables defined but not used? | |
204 ;;; Maybe add some kind of `export' declaration for this? | |
205 ;;; (With interactive functions being automatically exported?) | |
206 ;;; o Any reference to a variable, even one which is a no-op, will cause | |
207 ;;; the warning not to be given. Possibly we could use the for-effect | |
208 ;;; flag to determine when this reference is useless; possibly more | |
209 ;;; complex flow analysis would be necessary. | |
210 ;;; o If the optimizer deletes a variable reference, we might be left with | |
211 ;;; a bound-but-not-referenced warning. Generally this is ok, but not if | |
212 ;;; it's a synergistic result of macroexpansion. Need some way to note | |
213 ;;; that a varref is being optimized away? Of course it would be nice to | |
214 ;;; optimize away the binding too, someday, but it's unsafe today. | |
215 ;;; o (See byte-optimize.el for the optimization TODO list.) | |

790 ;;; | |

803 ;;; First, the source code is macroexpanded and optimized in various ways. | |
804 ;;; Then the resultant code is compiled into lapcode. Another set of | |
805 ;;; optimizations are then run over the lapcode. Then the variables and | |
806 ;;; constants referenced by the lapcode are collected and placed in the | |
807 ;;; constants-vector. (This happens now so that variables referenced by dead | |
808 ;;; code don't consume space.) And finally, the lapcode is transformed into | |
809 ;;; compacted byte-code. | |
810 ;;; | |
811 ;;; A distinction is made between variables and constants because the variable- | |
812 ;;; referencing instructions are more sensitive to the variables being near the | |

992 ;; This was a first attempt to add line numbers to the | |
993 ;; byte-compilation output. Unfortunately, it doesn't work | |
994 ;; perfectly: it reports the line number at the end of the form | |
995 ;; (which may be an entire function), rather than the line number | |
996 ;; of the actual problem. Doing this right is hard because we | |
997 ;; currently use the built-in Lisp parser to parse the entire form | |
998 ;; at once. What we basically need is a whole separate parser | |
999 ;; that annotates its output with line numbers. For example, we | |
1000 ;; might modify the parser in lread.c so that, with the right | |
1001 ;; option set, it replaces every Lisp object contained in the | |
1002 ;; structure it returns with a cons of that object and the line | |
1003 ;; number it was found on (determined by counting newlines, | |
1004 ;; starting from some arbitrary point). You then have two | |
1005 ;; options: (a) Modify the byte compiler so that everything that | |
1006 ;; compiles a form deals with the new annotated form rather than | |
1007 ;; the old one, or (b) The byte compiler saves this structure | |
1008 ;; while converting it into a normal structure that's given to the | |
1009 ;; various form handlers, which need no (or less) modification. | |
1010 ;; In the former case, finding the line number is trivial because | |
1011 ;; it's in the form. In the latter case, finding the line number | |
1012 ;; depends on having a unique Lisp object that can be looked up in | |
1013 ;; the annotated structure -- i.e. a list, vector, or string. | |
1014 ;; You'd have to look at the various places where errors are spit | |
1015 ;; out (not very many, really), and make sure that such a unique | |
1016 ;; object is available. Then you do a depth-first search through | |
1017 ;; the annotated structure to find the object. | |
1018 ;; | |
1019 ;; An alternative way of doing (b) that's probably much more | |
1020 ;; efficient (and easier to implement) is simply to have the | |
1021 ;; parser in lread.c annotate every unique object using a separate | |
1022 ;; hash table. This also eliminates the need for a search to find | |
1023 ;; the line number. In order to be fine-grained enough to get at | |
1024 ;; every symbol in a form -- e.g. if we want to pinpoint a | |
1025 ;; particular undefined variable in a function call -- we need to | |
1026 ;; annotate every cons, not just each list. We still have | |
1027 ;; (probably unimportant) problems with vectors, since all we have | |
1028 ;; is the start of the vector. If we cared about this, we could | |
1029 ;; store in the hash table a list of the line numbers for each | |
1030 ;; item in the vector, not just its start. | |
