| 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. | |
| 104 ;;; byte-compile-warnings List of warnings to issue, or t. May contain | |

| 127 ;;; generate .elc files which can be loaded into | |
| 128 ;;; generic emacs 19. | |
| 129 ;;; emacs-lisp-file-regexp Regexp for the extension of source-files; | |
| 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.) | |

| 992 ;; This was a first attempt to add line numbers to the | |

| 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 | |
