1 changes in sbcl-0.6.0 relative to sbcl-0.5.0:
3 * tidied up "make.sh" script
4 * tidied up system directory structure
5 * better "clean.sh" behavior
6 * added doc/FOR-CMUCL-DEVELOPERS
7 * many many small tweaks to output format, e.g. removing possibly-confusing
8 trailing #\. character in DESCRIBE-INSTANCE
9 * (EQUALP #\A 'A) no longer signals an error.
10 * new hashing code, including EQUALP hashing
11 * tidied up Lisp initialization and toplevel
12 * initialization files (e.g. /etc/sbclrc and $HOME/.sbclrc)
13 * command line argument processing
14 * added POSIX-GETENV function to deal with Unix-ish environment variables
15 * more-Unixy handling of *STANDARD-INPUT* and other Lisp streams, e.g.
16 terminating SBCL on EOF
17 * non-verbose GC by default
18 * There is no more "sbcl" shell script; the sbcl file is now the C
19 runtime executable (just like CMU CL).
20 * removed some unused fops, e.g. FOP-UNIFORM-VECTOR, FOP-CHARACTER, and
22 * tweaked debug-info.lisp and debug-int.lisp to make the debugger store
23 symbol and package information as Lisp native symbol and package objects
24 instead of strings naming symbols and strings naming packages. This way,
25 whenever packages are renamed (as in warm init), debug information is
26 transformed along with everything else.
27 * tweaked the optimization policy declarations which control the building
28 of SBCL itself. Now, among other things, the system no longer saves
29 source location debugging information. (This helps two problems at once
30 by reducing SBCL size and by keeping SBCL from trying to look for its
31 sources -- which may not exist -- when reporting errors.)
32 * added src/cold/chill.lisp, to let SBCL read its own cold sources for
33 debugging and testing purposes
34 * cleaned up printing, making the printer call PRINT-OBJECT for
35 instances, and using PRINT-UNREADABLE-OBJECT for most PRINT-OBJECT
36 methods, giving nearly-ANSI behavior
37 * converted almost all special variables to use *FOO* naming convention
38 * deleted PARSE-TIME functionality, since it can be done portably
39 * moved some files out of cold init into warm init
40 * deleted DEFUN UNDEFINED-VALUE, replaced (UNDEFINED-VALUE) forms
42 * regularized formatting of source files
43 * added an install.sh script
44 * fixed ridiculous memory usage of cross-compiler by making
45 compiler/alloc.lisp not try to do pooling unless it can hook
46 itself into the GC of the cross-compilation host. Now the system
47 builds nicely on my old laptop.
48 * added :SB-ALLOC in target-features.lisp-expr
49 * deleted mention of :ANSI-DOC from target-features.lisp-expr (since it
51 * re-did condition handling and note reporting in the compiler. Notes
52 are no longer handled by signalling conditions. Style warnings
53 and warnings are handled more correctly and reported in such a way
54 that it's easy to find one or the other in your output (so that you
55 can e.g. figure out which of many problems caused COMPILE-FILE to
57 * changed the severity of several compiler warnings from full WARNING
58 to STYLE-WARNING in order to conform with the ANSI spec; also changed
59 compiler note reporting so that it doesn't use the condition system
60 at all (and hence affects neither FAILURE-P nor WARNINGS-P in the
62 * made PROCLAIM and DECLAIM conform to ANSI. PROCLAIM is now an ordinary
63 function. As a consequence, START-BLOCK and END-BLOCK declarations are
64 no longer supported, since their implementation was deeply intertwingled
65 with the magical, non-ANSI treatment that PROCLAIM received in CMU CL.
66 * removed bogus "support" for compiler macros named (SETF FOO), and
67 removed the compiler macro for SETF INFO (but only after making a fool
68 of myself on the cmucl-imp mailing list by posting a bogus patch for
69 DEFINE-COMPILER-MACRO..)
70 * Compiled files containing forms which have side effects on the Lisp
71 reader (such as DEFPACKAGE forms) are now handled more correctly.
72 (Compiler queuing of top level lambdas has been suppressed by setting
73 *TOP-LEVEL-LAMBDA-MAX* to 0. )
74 * deleted various currently-unused source files, e.g. gengc.lisp. They
75 may be added back at some point e.g. when porting to other architectures,
76 but until they are it's distracting to distribute them and to try to
78 * deleted "UNCROSS couldn't recurse through.." style warnings, since
79 there were so many of them they're just distractions, and UNCROSS is
80 known to be able to handle the current sources
81 * moved PROFILE functionality into TRACE, so that it will be clear
82 how the wrapping and unwrapping of functions when you profile them
83 interacts with the wrapping and unwrapping of functions when you
84 trace them. (Actually, the functionality isn't there yet, but at least
85 the interface specification is there. Hopefully, the functionality will
86 arrive with some future maintenance release.)
87 * removed host-oops.lisp
88 * changed signature of QUIT function to allow UNIX-CODE argument
89 * fixed READ-SEQUENCE bug
90 * tweaked verbose GC output so that it looks more like the progress
91 output that ANSI specifies for functions like LOAD
92 * set up the system on sourceforge.com, with home pages, mailing lists, etc.
93 * added <http://sbcl.sourceforge.com> to the banner information printed by
96 changes in sbcl-0.6.1 relative to sbcl-0.6.0:
98 * changed build optimization from (SAFETY 1) to (SAFETY 3) as a short-term
99 fix for various type-unsafety bugs, e.g. failures with (LENGTH 123) and
100 (MAKE-LIST -1). In the longer term, it ought to become true
101 that declarations are assertions even at SAFETY 1. For now, it's not
102 quite true even at SAFETY 3, but it's at least more nearly true..
103 (Note that this change seems to increases the size of the system by
104 O(5%) and to decrease the speed of the compiler by 20% or more.)
105 * changed ALIEN printing to be much more abbreviated, as a short-term fix
106 for the problem of printing dozens of lines of distracting information
107 about low-level system machinery as part of the top stack frame
108 on entry to the debugger when an undefined function was called.
109 * tweaked the debugger's use of WITH-STANDARD-IO-SYNTAX so that *PACKAGE*
110 is not reset to COMMON-LISP-USER.
111 * Compilation of stuff related to dyncount.lisp has been made conditional
112 on the :SB-DYNCOUNT target feature, so that the ordinary core system is
113 smaller. The various dyncount-related symbols have been moved into
114 a new "SB-DYNCOUNT" package.
115 * tty-inspect.lisp has been renamed to inspect.lisp.
116 * unix-glibc2.lisp has been renamed to unix.lisp, and the :GLIBC2
117 feature has gone away. (When we eventually port to other flavors of
118 libc and/or Unix, we'll try to make the differences between flavors
119 invisible at the user level.)
120 * Various other *FEATURES* tags, and/or their associated conditionals,
121 have been removed if obsolescent, or given better documentation, or
122 sometimes given more-mnemonic names.
124 changes in sbcl-0.6.2 relative to sbcl-0.6.1:
126 * (Note that the way that the PCL macroexpansions were rewritten
127 to accommodate the change in DEFGENERIC below breaks binary
128 compatibility. That is, fasl files compiled under sbcl-0.6.1 may
129 not run under sbcl-0.6.2. Once we get out of alpha releases,
130 i.e. hit release 1.0.0, we'll probably try to maintain binary
131 compatibility between maintenance releases, e.g. between sbcl-1.4.3
132 and sbcl-1.4.4. Until then, however, it might be fairly common
133 for maintenance releases to break binary compatibility.)
134 * A bug in the calculation of WARNINGS-P and FAILURE-P in COMPILE-FILE
136 * The reporting of unhandled signals has been changed to print some
137 explanatory text as well as the report form. (Previously only
138 the report form was printed.)
139 * The macroexpansion for DEFGENERIC now DECLAIMs the function that
140 it defines, so that the compiler no longer issues undefined function
141 warnings for compiled-but-not-yet-loaded generic functions.
142 * The CLTL-style "LISP" and "USER" nicknames for the "COMMON-LISP"
143 and "COMMON-LISP-USER" packages have been removed. Now only the "CL"
144 and "CL-USER" standard nicknames from the "11.1.2 Standardized Packages"
145 section of the ANSI spec are supported.
146 * The "" nickname for the "KEYWORD" package has been removed.
147 The reader still handles symbol tokens which begin with a package marker
148 as keywords, but it doesn't expose its mechanism for doing so in the
149 (PACKAGE-NICKNAMES (FIND-PACKAGE "KEYWORD")) list.
150 * The system now issues STYLE-WARNINGs for contradictory TYPE
151 proclamations. (Warnings for contradictory FTYPE proclamations would
152 be nice too, but those can't be done usefully unless the type system
153 is made smarter about FUNCTION types.)
154 * The names of source files "*host-*.lisp" and "*target-*.lisp" have been
155 systematized, so that "*target-*.lisp is supposed to exist only on the
156 target and imply that there's a related file which exists on the
157 host, and *host-*.lisp is supposed to exist only on the host and imply
158 that there's a related file which exists on the target. This involves a
159 lot of renaming. Hopefully the acute confusion caused by the renaming
160 will be justified by the reduction in chronic confusion..
161 ** runtime-type.lisp -> early-target-type.lisp
162 ** target-type.lisp -> late-target-type.lisp
163 ** early-host-format.lisp -> early-format.lisp
164 ** late-host-format.lisp -> late-format.lisp
165 ** host-error.lisp -> misc-error.lisp
166 ** early-error.lisp -> early-target-error.lisp
167 ** late-error.lisp -> late-target-error.lisp
168 ** host-defboot.lisp -> early-defboot.lisp
169 ** code/misc.lisp -> code/target-misc.lisp
170 ** code/host-misc.lisp -> code/misc.lisp
171 ** code/numbers.lisp -> code/target-numbers.lisp
172 ** code/early-numbers.lisp -> numbers.lisp
173 ** early-host-type.lisp -> early-type.lisp
174 ** late-host-type.lisp -> late-type.lisp
175 ** host-typep.lisp -> typep.lisp
176 ** load.lisp -> target-load.lisp
177 ** host-load.lisp -> load.lisp
178 ** host-disassem.lisp -> disassem.lisp
179 ** host-insts.lisp -> insts.lisp
180 ** byte-comp.lisp -> target-byte-comp.lisp
181 ** host-byte-comp.lisp -> byte-comp.lisp
182 ** host-signal.lisp -> signal.lisp
183 ** host-defstruct.lisp -> defstruct.lisp
184 ** late-target-type.lisp -> deftypes-for-target.lisp
185 Furthermore, several other previously target-only files foo.lisp (e.g.
186 hash-table.lisp and random.lisp) have been split into a target-and-host
187 foo.lisp file and a target-only target-foo.lisp file, with their key type
188 definitions in the target-and-host part, so that the cross-compiler will
189 know more about target types.
190 * DEFSTRUCT BACKEND, and the BACKEND-valued *BACKEND* variable, have
191 gone away. In their place are various *BACKEND-FOO* variables
192 corresponding to the slots of the old structure.
193 * A bug which caused the SB-COLD bootstrap-time package to be propagated
194 into the target SBCL has been fixed.
195 * The chill.lisp system for loading cold code into a running SBCL
197 * Support for the CMU CL "scavenger hook" extension has been removed.
198 (It was undocumented and unused in the CMU CL sources that SBCL was
199 derived from, and stale in sbcl-0.6.1.)
200 * Various errors in the cross-compiler type system were detected
201 by running the cross-compiler with *TYPE-SYSTEM-INITIALIZED*
202 (enabling various consistency checks). Many of them were fixed,
203 but some hard problems remain, so the compiler is back to
204 running without *TYPE-SYSTEM-INITIALIZED* for now.
205 * As part of the cross-compiler type system cleanup, I implemented
206 DEF!TYPE and got rid of early-ugly-duplicates.lisp.
207 * I have started adding UNCROSS calls throughout the type system
208 and the INFO database. (Thus perhaps eventually the blanket UNCROSS
209 on cross-compiler input files will be able to go away, and various
211 * CONSTANTP now returns true for quoted forms (as explicitly required
214 changes in sbcl-0.6.3 relative to sbcl-0.6.2:
216 * The system still can't cross-compile itself with
217 *TYPE-SYSTEM-INITIALIZED* (and all the consistency checks that
218 entails), but at least it can compile more of itself that way
219 than it used to be able to, and various buglets which were uncovered
220 by trying to cross-compile itself that way have now been fixed.
221 * This release breaks binary compatibility again. This time
222 at least I've incremented the FASL file format version to 2, so that the
223 problem can be detected reliably instead of just causing weird errors.
224 * various new style warnings:
225 ** using DEFUN, DEFMETHOD, or DEFGENERIC to overwrite an old definition
226 ** using the deprecated EVAL/LOAD/COMPILE situation names in EVAL-WHEN
227 ** using the lexical binding of a variable named in the *FOO* style
228 * DESCRIBE has been substantially rewritten. It now calls DESCRIBE-OBJECT
229 as specified by ANSI.
230 * *RANDOM-STATE* is no longer automatically initialized from
231 (GET-UNIVERSAL-TIME), but instead from a constant seed. Thus, the
232 default behavior of the system is to repeat its behavior every time
233 it's run. If you'd like to change this behavior, you can always
234 explicitly set the seed from (GET-UNIVERSAL-TIME); whereas under the
235 old convention there was no comparably easy way to get the system to
236 repeat its behavior every time it was run.
237 * Support for the pre-CLTL2 interpretation of FUNCTION declarations as
238 FTYPE declarations has been removed, in favor of their ANSI
239 interpretation as TYPE FUNCTION declarations. (See p. 228 of CLTL2.)
240 * The quantifiers SOME, EVERY, NOTANY, and NOTEVERY no longer cons when
241 the types of their sequence arguments can be determined at compile time.
242 This is done through a new open code expansion for MAP which eliminates
243 consing for (MAP NIL ..), and reduces consing otherwise, when sequence
244 argument types can be determined at compile time.
245 * The optimizer now transforms COERCE into an identity operation when it
246 can prove that the coerced object is already of the correct type. (This
247 can be a win for machine generated code, including the output of other
248 optimization transforms, such as the MAP transform above.)
249 * Credit information has been moved from source file headers into CREDITS.
250 * Source file headers have been made more standard.
251 * The CASE macro now compiles without complaining even when it has
254 changes in sbcl-0.6.4 relative to sbcl-0.6.3:
256 * There is now a partial SBCL user manual (with some new text and some
257 text cribbed from the CMU CL manual).
258 * The beginnings of a profiler have been added (starting with the
259 CMU CL profiler and simplifying and cleaning up). Eventually the
260 main interface should be through the TRACE macro, but for now,
261 it's still accessed through vaguely CMU-CL-style functions and macros
262 exported from the package SB-PROFILE.
263 * Some problems left over from porting CMU CL to the new
264 cross-compilation bootstrap process have been cleaned up:
265 ** DISASSEMBLE now works. (There was a problem in using DEFMACRO
266 instead of SB!XC:DEFMACRO, compounded by an oversight on my
267 part when getting rid of the compiler *BACKEND* stuff.)
268 ** The value of *NULL-TYPE* was screwed up, because it was
269 being initialized before the type system knew the final
270 definition of the 'NULL type. This screwed up several key
271 optimizations in the compiler, causing inefficiency in all sorts
272 of places. (I found it because I wanted to understand why
273 GET-INTERNAL-RUN-TIME was consing.)
274 * fixed a bug in DEFGENERIC which was causing it to overwrite preexisting
275 PROCLAIM FTYPE information. Unfortunately this broke binary
276 compatibility again, since now the forms output by DEFGENERIC
277 to refer to functions which didn't exist in 0.6.3.
278 * added declarations so that SB-PCL::USE-CACHING-DFUN-P
279 can use the new (as of 0.6.3) transform for SOME into MAP into
281 * changed (MOD 1000000) type declarations for Linux timeval.tv_usec slot
282 values to (INTEGER 0 1000000), so that the time code will no longer
283 occasionally get blown up by Linux returning 1000000 microseconds
284 * PRINT-UNREADABLE-OBJECT has been tweaked to make the spacing of
285 its output conform to the ANSI spec. (Alas, this makes its output
286 uglier in the :TYPE T :IDENTITY NIL case, but them's the breaks.)
287 * A full call to MAP NIL with a single sequence argument no longer conses.
288 * fixes to problems pointed out by Martin Atzmueller:
289 * The manual page no longer talks about multiprocessing as though
290 it were currently supported.
291 * The ILISP support patches have been removed from the distribution,
292 because as of version 5.10.1, ILISP now supports SBCL without us
293 having to maintain patches.
294 * added a modified version of Raymond Toy's recent CMU CL patch for
295 EQUALP comparison of HASH-TABLE
297 changes in sbcl-0.6.5 relative to sbcl-0.6.4:
299 * Raymond Wiker's patches to port the system to FreeBSD have been merged.
300 * The build process now looks for GNU make under the default name "gmake",
301 instead of "make" as it used to. If GNU make is not available as "gmake"
302 on your system, you can change this default behavior by setting the
303 GNUMAKE environment variable.
304 * Replace #+SB-DOC with #!+SB-DOC in seq.lisp so that the system
305 can build without error under CMU CL.
307 changes in sbcl-0.6.6 relative to sbcl-0.6.5:
309 * DESCRIBE no longer tries to call itself recursively to describe
310 bound/fbound values, so that it no longer fails on symbols which are
311 bound to themselves (like keywords, T, and NIL).
312 * DESCRIBE now works on generic functions.
313 * The printer now prints less-screwed-up representations of closures
314 (not naively trying to bogusly use the %FUNCTION-NAME accessor on them).
315 * A private symbol is used instead of the :EMPTY keyword previously
316 used to mark empty slots in hash tables. Thus
317 (DEFVAR *HT* (MAKE-HASH-TABLE))
318 (SETF (GETHASH :EMPTY *HT*) :EMPTY)
319 (MAPHASH (LAMBDA (K V) (FORMAT T "~&~S ~S~%" K V)))
320 now does what ANSI says that it should. (You can still get
321 similar noncompliant behavior if bang on the hash table
322 implementation with all the symbols you get back from
323 DO-ALL-SYMBOLS, but at least that's a little harder to do.)
324 This breaks binary compatibility, since tests for equality to
325 :EMPTY are wired into things like the macroexpansion of
326 WITH-HASH-TABLE-ITERATOR in FASL files produced by earlier
328 * There's now a minimal placeholder implementation for CL:STEP,
330 * An obscure bug in the interaction of the normal compiler, the byte
331 compiler, inlining, and structure predicates has been patched
332 by setting the flags for the DEFTRANSFORM of %INSTANCE-TYPEP as
333 :WHEN :BOTH (as per Raymond Toy's suggestion on the cmucl-imp@cons.org
335 * Missing ordinary arguments in a macro call are now detected even
336 when the macro lambda list contains &KEY or &REST.
337 * The debugger no longer complains about encountering the top of the
338 stack when you type "FRAME 0" to explicitly instruct it to go to
339 the top of the stack. And it now prints the frame you request even
340 if it's the current frame (instead of saying "You are here.").
341 * As specified by ANSI, the system now always prints keywords
342 as #\: followed by SYMBOL-NAME, even when *PACKAGE* is the
344 * The default initial SIZE of HASH-TABLEs is now smaller.
345 * Type information from CLOS class dispatch is now propagated
346 into DEFMETHOD bodies, so that e.g.
347 (DEFMETHOD FOO ((X SINGLE-FLOAT))
349 is now basically equivalent to
350 (DEFMETHOD FOO ((X SINGLE-FLOAT))
351 (DECLARE (TYPE SINGLE-FLOAT X))
353 and the compiler can compile (+ X 123.0) as a SINGLE-FLOAT-only
354 operation, without having to do run-time type dispatch.
355 * The macroexpansion of DEFMETHOD has been tweaked so that it has
356 reasonable behavior when arguments are declared IGNORE or IGNORABLE.
357 * Since I don't seem to be making big file reorganizations very often
358 any more (and since my archive of sbcl-x.y.zv.tar.bz2 snapshots
359 is overflowing my ability to conveniently back them up), I've finally
360 checked the system into CVS. (The CVS repository is on my home system,
361 not at SourceForge -- putting it on SourceForge might come later.)
362 * SB-EXT:*GC-NOTIFY-STREAM* has been added, to control where the
363 high-level GC-NOTIFY-FOO functions send their output. (There's
364 still very little control of where low-level verbose GC functions
365 send their output.) The SB-EXT:*GC-VERBOSE* variable now controls
366 less than it used to -- the GC-NOTIFY-FOO functions are now under
367 the control of *GC-NOTIFY-STREAM*, not *GC-VERBOSE*.
368 * The system now stores the version string (LISP-IMPLEMENTATION-VERSION)
369 in only one place in the source code, and propagates it automatically
370 everywhere that it's needed. Thus e.g. when I bump the version from
371 0.6.6 to 0.6.7, I'll only need to modify the sources in one place.
372 * The C source files now include boilerplate legalese and documentation
373 at the head of each file (just as the Lisp source files already did).
374 * At Dan Barlow's suggestion, the hyperlink from the SBCL website
375 to his page will be replaced with a link to his new CLiki service.
377 changes in sbcl-0.6.7 relative to sbcl-0.6.6:
379 * The system has been ported to OpenBSD.
380 * The system now compiles with a simple "sh make.sh" on the systems
381 that it's supported on. I.e., now you no longer need to tweak
382 text in the target-features.lisp-expr and symlinks in src/runtime/
383 by hand, the make.sh takes care of it for you.
384 * The system is no longer so grossly inefficient when compiling code
385 involving vectors implemented as general (not simple) vectors (VECTOR T),
386 so code which dares to use VECTOR-PUSH-EXTEND and FILL-POINTER, or
387 which dares to use the various sequence functions on non-simple
388 vectors, takes less of a performance hit.
389 * There is now a primitive type predicate VECTOR-T-P
390 to test for the (VECTOR T) type, so that e.g.
391 (DEFUN FOO (V) (DECLARE (TYPE (VECTOR T) V)) (AREF V 3))
392 can now be compiled with some semblance of efficiency. (The old code
393 turned the type declaration into a full call to %TYPEP at runtime!)
394 * AREF on (VECTOR T) is still not fast, since it's still compiled
395 as a full call to SB-KERNEL:DATA-VECTOR-REF, but at least the
396 ETYPECASE used in DATA-VECTOR-REF is now compiled reasonably
397 efficiently. (The old version made full calls to SUBTYPEP at runtime!)
398 * (MAKE-ARRAY 12 :FILL-POINTER T) is now executed less inefficiently,
399 without making full calls to SUBTYPEP at runtime.
400 (Some analogous efficiency issues for non-simple vectors specialized to
401 element types other than T, or for non-simple multidimensional arrays,
402 have not been addressed. They could almost certainly be handled the
403 same way if anyone is motivated to do so.)
404 * The changes in array handling break binary compatibility, so
405 *BACKEND-FASL-FILE-VERSION* has been bumped to 4.
406 * (TYPEP (MAKE-ARRAY 12 :FILL-POINTER 4) 'VECTOR) now returns (VALUES T)
407 instead of (VALUES T T).
408 * By following the instructions that Dan Barlow posted to sbcl-devel
409 on 2 July 2000, I was able to enable primitive dynamic object
410 file loading code for Linux. The full-blown CMU CL LOAD-FOREIGN
411 functionality is not implemented (since it calls ld to resolve
412 library references automatically, requiring RUN-PROGRAM for its
413 implementation), but a simpler SB-EXT:LOAD-1-FOREIGN (which doesn't
414 try to resolve library references) is now supported.
415 * The system now flushes the standard output streams when it terminates,
416 unless QUIT is used with the RECKLESSLY-P option set. It also flushes
417 them at several other probably-convenient times, e.g. in each pass of
418 the toplevel read-eval-print loop, and after evaluating a form given
419 as an "--eval" command-line option. (These changes were motivated by a
420 discussion of stream flushing issues on cmucl-imp in August 2000.)
421 * The source transform for TYPEP of array types no longer assumes
422 that an array whose element type is a not-yet-defined type
423 is implemented as an array of T, but instead punts, so that the
424 type will be interpreted at runtime.
425 * There is now some support for cross-compiling in make.sh: each of
426 the phases of make.sh has its own script. (This should be transparent
427 to people doing ordinary, non-cross-compile builds.)
428 * Since my laptop doesn't have hundreds of megabytes of memory like
429 my desktop machine, I became more motivated to do some items on
430 my to-do list in order to reduce the size of the system a little:
431 ** Arrange for various needed-only-at-cold-init things to be
432 uninterned after cold init. To support this, those things have
433 been renamed from FOO and *FOO* to !FOO and *!FOO* (i.e., all
434 symbols with such names are now uninterned after cold init).
435 ** Bind SB!C::*TOP-LEVEL-LAMBDA-MAX* to a nonzero value when building
436 fasl files for cold load.
437 ** Remove the old compiler structure pooling code (which used to
438 be conditional on the target feature :SB-ALLOC) completely.
439 ** Redo the representation of some data in cold init to be more compact.
440 (I also looked into supporting byte compiled code at bootstrap time,
441 which would probably reduce the size of the system a lot, but that
442 looked too complicated, so I punted for now.)
443 * The maximum signal nesting depth in the src/runtime/ support code has
444 been reduced from 4096 to 256. (I don't know any reason for the very
445 large old value. If the new smaller value turns out to break something,
446 I'll probably just bump it back up.)
447 * PPRINT-LOGICAL-BLOCK is now pickier about the types of its arguments,
449 * Many, many bugs reported by Peter Van Eynde have been added to
450 the BUGS list; some have even been fixed.
451 * While enabling dynamic object file loading, I tried to make the
452 code easier to understand, renaming various functions and variables
453 with less ambiguous names, and changing some function calling
454 conventions to be Lispier (e.g. returning NIL instead of 0 for failure).
455 * While trying to figure out how to do the OpenBSD port, I tried to
456 clean up some of the code in src/runtime/. In particular, I dropped
457 support for non-POSIX signal handling, added various comments,
458 tweaked the code to reduce the number of compilation warnings, and
459 renamed some files to increase consistency.
460 * To support the new automatic configuration functionality in make.sh,
461 the source file target-features.lisp-expr has been replaced with the
462 source file base-target-features.lisp-expr and the machine-generated
463 file local-target-features.lisp-expr.
464 * fixed a stupid quoting error in make.sh so that using CMU CL
465 "lisp -batch" as cross-compilation host works again
467 changes in sbcl-0.6.8 relative to sbcl-0.6.7:
469 * The system is now under CVS at SourceForge (instead of the
470 CVS repository on my home machine).
471 * The new signal handling code has been tweaked to treat register
472 contents as (UNSIGNED-BYTE 32), as the old CMU CL code did,
473 instead of (SIGNED-BYTE 32), as the C header files have it. (Code
474 downstream, e.g. in debug-int.lisp, has implicit dependencies
475 on the unsignedness of integer representation of machine words,
476 and that caused the system to bomb out with infinite regress
477 when trying to recover from type errors involving signed values,
478 e.g. (BUTLAST '(1 2 3) -1).)
479 * (BUTLAST NIL) and (NBUTLAST NIL) now return NIL as they should.
480 (This was one of the bugs Peter Van Eynde reported back in July.)
481 * The system now uses code inspired by Colin Walters' O(N)
482 implementation of MAP (from the cmucl-imp@cons.org mailing
483 list, 2 September 2000) when it can't use a DEFTRANSFORM to
484 inline the MAP operation, and there is more than one
485 sequence argument to the MAP call (so that it can't just
486 do ETYPECASE once and for all based on the type of the
487 single sequence argument). (The old non-inline implementation
488 of the general M-argument sequence-of-length-N case required
489 O(M*N*N) time when any of the sequence arguments were LISTs.)
490 * The QUIT :UNIX-CODE keyword argument has been renamed to
491 QUIT :UNIX-STATUS. (The old name still works, but is deprecated.)
492 * Raymond Wiker's patches to port RUN-PROGRAM from CMU CL to SBCL
494 * Raymond Wiker's patches to port dynamic loading from Linux to
495 FreeBSD have been added.
496 * The BUGS file is now more nearly up to date, thanks in large part
497 to Martin Atzmueller's review of it.
498 * The debugger now flushes standard output streams before it begins
499 its output ("debugger invoked" and so forth).
500 * The core version number and fasl file version number have both
501 been incremented, because of incompatible changes in the layout
503 * FINISH-OUTPUT is now called more consistently on QUIT. (It
504 used to not be called for a saved Lisp image.)
505 * Martin Atzmueller's version of a patch to fix a compiler crash,
506 as posted on sbcl-devel 13 September 2000, has been installed.
507 * Instead of installing Martin Atzmueller's patch for the
508 compiler transform for SUBSEQ, I deleted the compiler transform,
509 and transforms for some similar consing operations.
510 * A bug in signal handling which kept TRACE from working on OpenBSD
512 * added enough DEFTRANSFORMs to allow (SXHASH 'FOO) to be optimized
513 away by constant folding
514 * The system now defines its address space constants in one place
515 (in the Lisp sources), and propagates them automatically elsewhere
516 (through GENESIS and the sbcl.h file). Therefore, patching the
517 address map is less unnecessarily tedious and error-prone. The
518 Lisp names of address space constants have also been systematized.
519 * CVS tags like dollar-Header-dollar have been removed from
520 the sources, because they have never saved me trouble and
521 they've been source of trouble working with patches and other
522 diff-related operations.
523 * fixed the PROG1-vs.-PROGN bug in HANDLER-BIND (reported by
524 ole.rohne@cern.ch on cmucl-help@cons.org 2000-10-25)
526 changes in sbcl-0.6.9 relative to sbcl-0.6.8:
528 * DESCRIBE now works on CONDITION objects.
529 * The debugger now handles errors which arise when trying to print
530 *DEBUG-CONDITION*, so that it's less likely to fall into infinite
532 * The build system now uses an additional file, customize-target-features.lisp,
533 to allow local modifications to the target *FEATURES* list. (The point of
534 this is that now I can set up a custom configuration, e.g. with :SB-SHOW
535 debugging features enabled, without having to worry about propagating it
536 into everyone's system when I do a "cvs update".) When no
537 customize-target-features.lisp file exists, the target *FEATURES* list
538 should be constructed the same way as before.
539 * fixed bugs in DEFCONSTANT ANSI-compatibility:
540 ** DEFCONSTANT now tests reassignments using EQL, not EQUAL, in order to
541 warn about behavior which is undefined under the ANSI spec. Note: This
542 is specified by ANSI, but it's not very popular with programmers.
543 If it causes you problems, take a look at the new SB-INT:DEFCONSTANT-EQX
544 macro in the SBCL sources for an example of a workaround which you
545 might use to make portable ANSI-standard code which does what you want.
546 ** DEFCONSTANT's implementation is now based on EVAL-WHEN instead of on
547 pre-ANSI IR1 translation magic, so it does the ANSI-specified thing
548 when it's used as a non-toplevel form. (This is required in order
549 to implement the DEFCONSTANT-EQX macro.)
550 ** (DEFCONSTANT X 1) (DEFVAR X) (SETF X 2) no longer "works".
551 ** Unfortunately, non-toplevel DEFCONSTANT forms can still do some
552 funny things, due to bugs in the implementation of EVAL-WHEN
553 (bug #IR1-3). This probably won't be fixed until 0.7.x. (Fortunately,
554 non-toplevel DEFCONSTANTs are uncommon.)
555 * The core file version number and fasl file version number have been
556 incremented, because the old noncompliant DEFCONSTANT behavior involved
557 calling functions which no longer exist, and because I also took the
558 opportunity to chop an unsupported slot out of the DEBUG-SOURCE structure.
559 * fixed bug 1 (error handling before read-eval-print loop starts), and
560 redid debugger restarts and related debugger commands somewhat while
562 ** The QUIT debugger command is gone, since it did something
563 rather different than the SB-EXT:QUIT command, and since it never
564 worked properly outside the main toplevel read/eval/print loop.
565 Invoking the new TOPLEVEL restart provides the same functionality.
566 ** The GO debugger command is also gone, since you can just invoke
567 the CONTINUE restart directly instead.
568 ** The TOP debugger command is also gone, since it's redundant with the
569 FRAME 0 command, and since it interfered with abbreviations for the
571 * The system now recovers better from non-PACKAGE values of the *PACKAGE*
573 * The system now understands compound CONS types (e.g. (CONS FIXNUM T))
574 as required by ANSI. (thanks to Douglas Crosher's CMU CL patches, with
575 some porting work by Martin Atzmueller)
576 * Martin Atzmueller reviewed the CMU CL mailing lists and came back
577 with a boatload of patches which he ported to SBCL. Now that those
579 ** The system tries to make sure that its low-priority messages
580 are prefixed by semicolons, to help people who like to use
581 syntax highlighting in their ILISP buffer. (This patch
582 was originally due to Raymond Toy.)
583 ** The system now optimizes INTEGER-LENGTH better, thanks to more
584 patches originally written by Raymond Toy.
585 ** The compiler understands coercion between single-value and
586 multiple-VALUES type expressions better, getting rid of some very
587 weird behavior, thanks to patches originally by Robert MacLachlan
589 ** The system understands ANSI-style non-KEYWORD &KEY arguments in
590 lambda lists, thanks to a patch originally by Pierre Mai.
591 ** The system no longer bogusly warns about "abbreviated type
593 ** The compiler gets less confused by inlining and RETURN-FROM,
594 thanks to some patches originally by Tim Moore.
595 ** The system no longer hangs when dumping circular lists to fasl
596 files, thanks to a patch originally from Douglas Crosher.
597 * Martin Atzmueller also fixed ROOM, so that it no longer fails with an
598 undefined function error.
599 * gave up on fixing bug 3 (forbidden-by-ANSI warning for type mismatch
600 in structure slot initforms) for now, documented workaround instead:-|
601 * fixed bug 4 (no WARNING for DECLAIM FTYPE of slot accessor function)
602 * fixed bug 5: added stubs for various Gray stream functions called
603 in the not-a-CL:STREAM case, so that even when Gray streams aren't
604 installed, at least appropriate type errors are generated
605 * fixed bug 8: better reporting of various PROGRAM-ERRORs
606 * fixed bug 9: IGNORE and IGNORABLE now work reasonably and more
607 consistently in DEFMETHOD forms.
608 * removed bug 21 from BUGS, since Martin Atzmueller points out that
609 it doesn't seem to affect SBCL after all
610 * The C runtime system now builds with better optimization and many
611 fewer warnings, thanks to lots of cleanups by Martin Atzmueller.
613 changes in sbcl-0.6.10 relative to sbcl-0.6.9:
615 * A patch from Martin Atzmueller seems to have solved the SIGINT
616 problem, and as far as we know, signal-handling now works cleanly.
617 (If you find any new bugs, please report them!)
618 * The system no longer defaults Lisp source file names to types
619 ".l", ".cl", or ".lsp", but only to ".lisp".
620 * The compiler no longer uses special default file extensions for
621 byte-compiled code. (The ANSI definition of COMPILE-FILE-PATHNAME
622 seems to expect a single default extension for all compiled code,
623 and there's no compelling reason to try to stretch the standard
624 to allow two different extensions.) Instead, byte-compiled files
625 default to the same extension as native-compiled files.
626 * Fasl file format version numbers have increased again, because
627 a rearrangement of internal implementation packages made some
628 dumped symbols in old fasl files unreadable in new cores.
629 * DECLARE/DECLAIM/PROCLAIM logic is more nearly ANSI in general, with
630 many fewer weird special cases.
631 * Bug #17 (differing COMPILE-FILE behavior between logical and
632 physical pathnames) has been fixed, and some related misbehavior too,
633 thanks to a patch from Martin Atzmueller.
634 * Bug #30 (reader problems) is gone, thanks to a CMU CL patch
635 by Tim Moore, ported to SBCL by Martin Atzmueller.
636 * Martin Atzmueller fixed several filesystem-related problems,
637 including bug #36, in part by porting CMU CL patches, which were
638 written in part by Paul Werkowski.
639 * More compiler warnings in src/runtime/ are gone, thanks to
640 more patches from Martin Atzmueller.
641 * Martin Atzmueller pointed out that bug 37 was fixed by his patches
644 changes in sbcl-0.6.11 relative to sbcl-0.6.10:
645 * Martin Atzmueller pointed out that bugs #9 and #25 are gone in
647 * bug 34 fixed by Martin Atzmueller: dumping/loading instances works
649 * fixed bug 40: TYPEP, SUBTYPEP, UPGRADED-ARRAY-ELEMENT-TYPE,
650 and UPGRADED-COMPLEX-PART-TYPE now work better with of compound
651 types built from undefined types, e.g. '(VECTOR SOME-UNDEF-TYPE).
652 * DESCRIBE now works on structure objects again.
653 * Most function call argument type mismatches are now handled as
654 STYLE-WARNINGs instead of full WARNINGs, since the compiler doesn't
655 know whether the function will be redefined before the call is
656 executed. (The compiler could flag local calls with full WARNINGs,
657 as per the ANSI spec "3.2.2.3 Semantic Constraints", but right now
658 it doesn't keep track of enough information to know whether calls
659 are local in this sense.)
660 * Compiler output is now more verbose, with messages truncated
661 later than before. (There should be some supported way for users
662 to override the default verbosity, but I haven't decided how to
663 provide it yet, so this behavior is still controlled by the internal
664 SB-C::*COMPILER-ERROR-PRINT-FOO* variables in
665 src/compiler/ir1util.lisp.)
666 * Fasl file format version numbers have increased again, because
667 support for the Gray streams extension changes the layout of the
668 system's STREAM objects.
669 * The Gray subclassable streams extension now works, thanks to a
670 patch from Martin Atzmueller.
671 * The full LOAD-FOREIGN extension (not just the primitive
672 LOAD-FOREIGN-1) now works, thanks to a patch from Martin Atzmueller.
673 * The default behavior of RUN-PROGRAM has changed. Now, unlike CMU CL
674 but like most other programs, it defaults to copying the Unix
675 environment from the original process instead of starting the
676 new process in an empty environment.
677 * Extensions which manipulate the Unix environment now support
678 an :ENVIRONMENT keyword option which doesn't smash case or
679 do other bad things. The CMU-CL-style :ENV option is retained
680 for porting convenience.
681 * LOAD-FOREIGN (and LOAD-1-FOREIGN) now support logical pathnames,
682 as per Daniel Barlow's suggestion and Martin Atzmueller's patch
684 changes in sbcl-0.6.12 relative to sbcl-0.6.11:
685 * incompatible change: The old SB-EXT:OPTIMIZE-INTERFACE declaration
686 is no longer recognized. I apologize for this, because it was
687 listed in SB-EXT as a supported extension, but I found that
688 its existing behavior was poorly specified, as well as incorrectly
689 specified, and it looked like too much of a mess to straighten it
690 out. I have enough on my hands trying to get ANSI stuff to work..
691 * many patches ported from CMU CL by Martin Atzmueller, with
692 half a dozen bug fixes in pretty-printing and the debugger, and
693 half a dozen others elsewhere
694 * fixed bug 13: Floating point infinities are now supported again.
695 They might still be a little bit flaky, but thanks to bug reports
696 from Nathan Froyd and CMU CL patches from Raymond Toy they're not
697 as flaky as they were.
698 * The --noprogrammer command line option is now supported. (Its
699 behavior is slightly different in detail from what the old man
700 page claimed it would do, but it's still appropriate under the
701 same circumstances that the man page talks about.)
702 * The :SB-PROPAGATE-FLOAT-TYPE and :SB-PROPAGATE-FUN-TYPE features
703 are now supported, and enabled by default. Thus, the compiler can
704 handle many floating point and complex operations much less
705 inefficiently. (Thus e.g. you can implement a complex FFT
707 * The compiler now detects type mismatches between DECLAIM FTYPE
708 and DEFUN better, and implements CHECK-TYPE more correctly, and
709 SBCL builds under CMU CL again despite its non-ANSI EVAL-WHEN,
710 thanks to patches from Martin Atzmueller.
711 * various fixes to make the cross-compiler more portable to
712 ANSI-conforming-but-different cross-compilation hosts (notably
713 Lispworks for Windows, following bug reports from Arthur Lemmens)
714 * A bug in READ-SEQUENCE for CONCATENATED-STREAM, and a gross
715 ANSI noncompliance in DEFMACRO &KEY argument parsing, have been
716 fixed thanks to Pierre Mai's CMU CL patches.
717 * fixes to keep the system from overflowing internal counters when
718 it tries to use i/o buffers larger than 16M bytes
719 * fixed bug 45a: Various internal functions required to support
720 complex special functions have been merged from CMU CL sources.
721 (When I was first setting up SBCL, I misunderstood a compile-time
722 conditional #-OLD-SPECFUN, and so accidentally deleted them.)
723 * improved support for type intersection and union, fixing bug 12
724 (e.g., now (SUBTYPEP 'KEYWORD 'SYMBOL)=>T,T) and some other
725 more obscure bugs as well
726 * some steps toward byte-compiling non-performance-critical
727 parts of the system, courtesy of patches from Martin Atzmueller
728 * Christophe Rhodes has made some debian packages of sbcl at
729 <http://www-jcsu.jesus.cam.ac.uk/ftp/pub/debian/lisp>.
730 From his sbcl-devel e-mail of 2001-04-08 they're not completely
731 stable, but are nonetheless usable. When he's ready, I'd be happy
732 to add them to the SourceForge "File Releases" section. (And if
733 anyone wants to do RPMs or *BSD packages, they'd be welcome too.)
734 * new fasl file format version number (because of changes in
735 internal representation of (OR ..) types to accommodate the new
736 support for (AND ..) types, among other things)
738 changes in sbcl-0.6.13 relative to sbcl-0.6.12:
739 * a port to the Compaq/DEC Alpha CPU, thanks to Dan Barlow
740 * Martin Atzmueller ported Tim Moore's marvellous CMU CL DISASSEMBLE
741 patch, so that DISASSEMBLE output is much nicer.
742 * The code in the SB-PROFILE package now seems reasonably stable.
743 I still haven't decided what the final interface should look like
744 (I'd like PROFILE to interact cleanly with TRACE, since both
745 facilities use function encapsulation) but if you have a need
746 for profiling now, you can probably use it successfully with
747 the current CMU-CL-style interface.
748 * Pathnames and *DEFAULT-DIRECTORY-DEFAULTS* are much more
749 ANSI-compliant, thanks to various fixes and tests from Dan Barlow.
750 Also, at Dan Barlow's suggestion, TRUENAME on a dangling symbolic
751 link now returns the dangling link itself, and for similar
752 reasons, TRUENAME on a cyclic symbolic link returns the cyclic
753 link itself. (In these cases the old code signalled an error and
754 looped endlessly, respectively.) Thus, DIRECTORY now works even
755 in the presence of dangling and cyclic symbolic links.
756 * Compiler trace output (the :TRACE-FILE option to COMPILE-FILE)
757 is now a supported extension again, since the consensus on
758 sbcl-devel was that it can be useful for ordinary development
759 work, not just for debugging SBCL itself.
760 * The default for SB-EXT:*DERIVE-FUNCTION-TYPES* has changed to
761 NIL, i.e. ANSI behavior, i.e. the compiler now recognizes
762 that currently-defined functions might be redefined later with
763 different return types.
764 * Hash tables can be printed readably, as inspired by CMU CL code
765 of Eric Marsden and SBCL code of Martin Atzmueller.
766 * better error handling in CLOS method combination, thanks to
767 Martin Atzmueller porting Pierre Mai's CMU CL patches
768 * more overflow fixes for >16Mbyte I/O buffers
769 * A bug in READ has been fixed, so that now a single Ctrl-D
770 character suffices to cause end-of-file on character streams.
771 In particular, now you only need one Ctrl-D at the command
772 line (not two) to exit SBCL.
773 * fixed bug 26: ARRAY-DISPLACEMENT now returns (VALUES NIL 0) for
775 * fixed bug 107 (reported as a CMU CL bug by Erik Naggum on
776 comp.lang.lisp 2001-06-11): (WRITE #*101 :RADIX T :BASE 36) now
777 does the right thing.
778 * The implementation of some type tests, especially for CONDITION
779 types, is now tidier and maybe faster, due to CMU CL code
780 originally by Douglas Crosher, ported by Martin Atzmueller.
781 * Some math functions have been fixed, and there are new
782 optimizers for deriving the types of COERCE and ARRAY-ELEMENT-TYPE,
783 thanks to Raymond Toy's work on CMU CL, ported by Martin Atzmueller.
784 * (There are also some new optimizers in contrib/*-extras.lisp. Those
785 aren't built into sbcl-0.6.13, but are a sneak preview of what's
786 likely to be built into sbcl-0.7.0.)
787 * A bug in COPY-READTABLE was fixed. (Joao Cachopo's patch to CMU
788 CL, ported to SBCL by Martin Atzmueller)
789 * DESCRIBE now gives more information in some cases. (Pierre Mai's
790 patch to CMU CL, ported to SBCL by Martin Atzmueller)
791 * Martin Atzmueller and Bill Newman fixed some bugs in INSPECT.
792 * There's a new slam.sh hack to shorten the edit/compile/debug
793 cycle for low-level changes to SBCL itself, and a new
794 :SB-AFTER-XC-CORE target feature to control the generation of
795 the after-xc.core file needed by slam.sh.
796 * minor incompatible change: The ENTRY-POINTS &KEY argument to
797 COMPILE-FILE is no longer supported, so that now every function
798 gets an entry point, so that block compilation looks a little
799 more like the plain vanilla ANSI section 3.2.2.3 scheme.
800 * minor incompatible change: SB-EXT:GET-BYTES-CONSED now
801 returns the number of bytes consed since the system started,
802 rather than the number consed since the first time the function
803 was called. (The new definition parallels ANSI functions like
804 CL:GET-INTERNAL-RUN-TIME.)
805 * minor incompatible change: The old CMU-CL-style DIRECTORY options,
806 i.e. :ALL, :FOLLOW-LINKS, and :CHECK-FOR-SUBDIRS, are no longer
807 supported. Now DIRECTORY always does the abstract Common-Lisp-y
808 thing, i.e. :ALL T :FOLLOW-LINKS T :CHECK-FOR-SUBDIRS T.
809 * Fasl file version numbers are now independent of the target CPU,
810 since historically most system changes which required version
811 number changes have affected all CPUs equally. Similarly,
812 the byte fasl file version is now equal to the ordinary
815 changes in sbcl-0.7.0 relative to sbcl-0.6.13:
816 * There are new compiler optimizations for various functions: FIND,
817 POSITION, FIND-IF, POSITION-IF, FILL, COERCE, TRUNCATE, FLOOR, and
818 CEILING. Mostly these should be transparent, but there's one
819 potentially-annoying problem (bug 117): when the compiler inline
820 expands the FIND/POSITION family of functions and does type
821 analysis on the result, it can find control paths which have
822 type mismatches, and when it can't prove that they're not taken,
823 it will issue WARNINGs about the type mismatches. It's not clear
824 how to make the compiler smart enough to fix this in general, but
825 a workaround is given in the entry for 117 in the BUGS file.
826 * The doc/cmucl/ directory, containing old CMU CL documentation,
827 is no longer part of the base system. The files which used to
828 be in the doc/cmucl/ directory are now available as
829 <ftp://sbcl.sourceforge.net/pub/sbcl/cmucl-docs.tar.bz2>.
830 * The default value of *BYTES-CONSED-BETWEEN-GCS* has been
831 doubled, to 4 million. (If your application spends a lot of time
832 GCing and you have a lot of RAM, you might want to experiment with
833 increasing it even more.)
834 ?? The system's handling of top-level forms and EVAL-WHEN is now
835 more ANSI-compliant, fixing bugs
838 It's also done by much newer code, so there might be some new bugs,
839 but hopefully if so they'll be less fundamental and more fixable.
840 * PPRINT-LOGICAL-BLOCK now copies the *PRINT-LINES* value on entry
841 and uses that copy, rather than the current dynamic value, when
842 it's trying to decide whether to truncate output . Thus e.g.
843 (let ((*print-lines* 50))
844 (pprint-logical-block (stream nil)
846 (let ((*print-lines* 8))
847 (print (aref possiblybigthings i) stream)))))
848 should truncate the logical block only at 50 lines, instead of
849 often truncating it at 8 lines.
850 * :SB-CONSTRAIN-FLOAT-TYPE, :SB-PROPAGATE-FLOAT-TYPE, and
851 :SB-PROPAGATE-FUN-TYPE are no longer considered to be optional
852 features. Instead, the code that they used to control is always
853 built into the system.
854 ?? lots of tidying up internally: renaming things so that names are
855 more systematic and consistent, converting C macros to inline
856 functions, systematizing indentation
857 * The fasl file version number changed again, for any number of
860 planned incompatible changes in 0.7.x:
861 * The debugger prompt sequence now goes "5]", "5[2]", "5[3]", etc.
862 as you get deeper into recursive calls to the debugger command loop,
863 instead of the old "5]", "5]]", "5]]]" sequence. (I was motivated
864 to do this when squabbles between ILISP and SBCL left me
865 very deeply nested in the debugger.)
866 * The fasl file extension may change, perhaps to ".fasl".
867 * The default output representation for unprintable ASCII characters
868 which, unlike e.g. #\Newline, don't have names defined in the
869 ANSI Common Lisp standard, may change to their ASCII symbolic
870 names: #\Nul, #\Soh, #\Stx, etc.
871 * INTERNAL-TIME-UNITS-PER-SECOND might increase, e.g. to 1000.
872 * FASL file extensions change to ".fasl", instead of the various
873 CPU-dependent values (".x86f", ".axpf", etc.) inherited from CMU CL.
874 * MAYBE-INLINE will probably go away at some point, maybe 0.7.x,
875 maybe later, in favor of the ANSI-recommended idiom for making
876 a function optionally inline.
877 * When the profiling interface settles down, maybe in 0.7.x, maybe
878 later, it might impact TRACE. They both encapsulate functions, and
879 it's not clear yet how e.g. UNPROFILE will interact with TRACE
880 and UNTRACE. (This shouldn't matter, though, unless you are
881 using profiling. If you never profile anything, TRACE should
882 continue to behave as before.)
883 * The BYTE-COMPILE &KEY argument for COMPILE-FILE is deprecated,
884 since this behavior can be controlled by (DECLAIM (OPTIMIZE (SPEED 0))).
