CMUCL 21e

The CMUCL project is pleased to announce the release of CMUCL 21e. This is a major release which contains numerous enhancements and bug fixes from the 21d release.

CMUCL is a free, high performance implementation of the Common Lisp programming language which runs on most major Unix platforms. It mainly conforms to the ANSI Common Lisp standard. CMUCL provides a sophisticated native code compiler; a powerful foreign function interface; an implementation of CLOS, the Common Lisp Object System, which includes multi-methods and a meta-object protocol; a source-level debugger and code profiler; and an Emacs-like editor implemented in Common Lisp. CMUCL is maintained by a team of volunteers collaborating over the Internet, and is mostly in the public domain.

New in this release:

• Known issues:

• Feature enhancements

• Changes

  • Update to ASDF 3.3.6
  • The default external format is :utf-8 instead of :iso8859-1.

• ANSI compliance fixes:

• Bug fixes:

  • #97 Fixes stepping through the source forms in the debugger. This has been broken for quite some time, but it works now.

• Gitlab tickets:

  • #68 gcc8.1.1 can't build lisp. Change optimization from -O2 to -O1.
  • #72 CMU user manual now part of cmucl-site.
  • #73 Update clx from upstream clx.
  • #77 Added tests for sqrt for exceptional values.
  • #79 Autoload ASDF when calling REQUIRE the first time. User's no longer have to explicitly load ASDF anymore.
  • #80 Use ASDF to load contribs. cmu-contribs still exists but does nothing. The contrib names are the same, except it's best to use a keyword instead of a string. So, :contrib-demos instead of "contrib-demos".
  • #81 Added contribs from Eric Marsden.
  • #82 Replace bc with expr in GNUMakefile.
  • #86 Building with gcc 8 and later works when using -O2 optimization.
  • #90 Some static symbols have been removed. This probably makes the fasl files incompatible with older versions.
  • #91 Loop destructuring no longer incorrectly signals an error.
  • #95 Disassembler syntax of x86 je and movzx is incorrect.
  • #97 Define and use ud2 instruction instead of int3. Fixes single-stepping.
  • #98 fstpd is not an Intel instruction; disassemble as fstp dword ptr [addr].
  • #100 ldb prints out Unicode base-chars correctly instead of just the low 8 bits.
  • #103 RANDOM-MT19937-UPDATE assembly routine still exists.
  • #104 Single-stepping broken (fixed via #97).
  • #107 Replace u_int8_t with uint8_t.
  • #108 Update ASDF.
  • #112 CLX can't connect to X server via inet sockets.
  • #113 REQUIRE on contribs can pull in the wrong things via ASDF.
  • #120 SOFTWARE-VERSION is implemented in C.
  • #121 Wrong column index in FILL-POINTER-OUTPUT-STREAM
  • #122 gcc 11 can't build cmucl
  • #124 directory with :wild-inferiors doesn't descend subdirectories
  • #125 Linux unix-stat returning incorrect values
  • #127 Linux unix-getpwuid segfaults when given non-existent uid.
  • #128 QUIT accepts an exit code.
  • #130 Move file-author to C.
  • #132 Ansi test RENAME-FILE.1 no longer fails.
  • #134 Handle the case of (expt complex complex-rational).
  • #136 ensure-directories-exist should return the given pathspec.
  • #139 *default-external-format* defaults to :utf-8; add alias for :locale external format.
  • #140 External format for streams that are not file-stream's.
  • #141 Disallow locales that are pathnames to a localedef file.
  • #142 (random 0) signals incorrect error.
  • #143 LISTEN doesn't signal error when given more than one arg
  • #147 stream-line-column method missing for fundamental-character-output-stream.
  • #149 Call setlocale(3C) on startup.
  • #150 Add aliases for external format cp949 and euckr.
  • #151 Change *default-external-format* to :utf-8.
  • #152 Add new external format, :locale as an alias to the codeset from LANG and friends.
  • #!53 Terminals default to an encoding of :locale.
  • #155 Wrap help strings neatly.
  • #157 (directory "foo/**/") only returns directories now.
  • #158 Darwin uses utf-8, but we don't support all the rules for pathnames.
  • #162 *filename-encoding* defaults to :null to mean no encoding.
  • #163 Add command-line option -version and --version to get lisp version.
  • #165 Avoid inserting NIL into simple LOOP from FORMAT.
  • #166 Fix incorrect type declaration for exponent from integer-decode-float.
  • #167 Low bound for decode-float-exponent type was off by one.
  • #168 Don't use negated forms for jmp instructions when possible.
  • #169 Add pprinter for define-vop and sc-case.
  • #172 Declare pathname-match-p as returning nil or pathname.
  • #173 Add pprinter for define-assembly-routine.
  • #176 SHORT-SITE-NAME and LONG-SITE-NAME return NIL.
  • #177 Add pprinter for deftransform and defoptimizer.
  • #192 Print radix marker in disassemblies and adjust note column to be larger for x86.
  • #193 Treat NIL and :UNSPECIFIC as equivalent when comparing pathnames with equal.

• Other changes:

• Improvements to the PCL implementation of CLOS:

• Changes to building procedure:

This release is not binary compatible with code compiled using CMUCL 21d; you will need to recompile FASL files.
