      o Add new condition REFERENCE-CONDITION which is used to include · 04f6e86b
      rtoy authored
        reference information for other conditions.  This condition prints
        out a short message saying to look somewhere appropriate.
      o Use REFERENCE-CONDITION for the CONSTANT-MODIFIED condition.
      
      (Based on SBCL's REFERENCE-CONDITION.)
      
      This needs work to add more references.

      Add support for sysinfo on Solaris. · 3b086fb1
      rtoy authored
      code/unix.lisp:
      o Add UNIX-SYSINFO and appropriate constants.
      
      code/exports.lisp:
      o Export UNIX-SYSINFO and corresponding constants.
      
      code/sparc-svr4-vm.lisp:
      o Use UNIX-SYSINFO to provide better values for MACHINE-TYPE and
        MACHINE-VERSION. Instead of the generic "Ultrasparc", we can return
        things like "sun4u" and "SUNW,Sun-Blade-1500".
      
      Use bootfiles/19c/boot-2005-12-2.lisp to bootstrap this change.  Only
      needed for sparc.

      Alignment of objects inside of structures is weird on Mac OS X. The · 00284c2f
      rtoy authored
      first slot gets the natural alignment, but all subsequent slots get
      4-byte alignment, even if the object is a double or long long.
      
      o Add EMBEDDED-ALIGNMENT to compute this alignment of embedded
        objects.
      o Modify PARSE-ALIEN-RECORD-FIELDS to cause the appropriate alignment
        of slots in a struct.

      Fix bug in peek-char for Gray streams. Reported by Walter Pelissero, · 698807d6
      rtoy authored
      cmucl-imp, 2005-11-10, with fix.
      
      o Apply Walter's fix, because it was missing the fifth arg to
        GENERALIZED-PEEKING-MECHANISM.
      o Change GENERALIZED-PEEKING-MACHINISM to use keyword args instead of
        optional args, to prevent this kind of bug.

      Add an extension to allow printing pathnames using the syntax · 527266cd
      rtoy authored
      #P(<make-pathname args).  So most pathnames can be printed readably,
      even if they have weird components.  But we don't handle search-lists
      and patterns very well because we don't have readable syntax for
      those.
      
      code/sharpm.lisp:
      o Make the #P reader accept lists and apply make-pathname on them to
        create the pathname
      
      code/pathname.lisp:
      o If a pathname has no namestring, then try to print out the pathname
        object using #P(foo) syntax, if possible.  If not possible, just
        print out the pathname unreadably, as we used to.
      o Put some conditional newlines when printing out unprintable
        pathnames so it wraps a bit better.  (Needs work.)

      Fix ansi-test logical-pathname.error.2 which was failing because · 98ab1c48
      rtoy authored
      LOGICAL-PATHNAME-NAMESTRING-P wasn't defined anywhere.
      
      o Add LOGICAL-PATHNAME-NAMESTRING-P and adjust LOGICAL-PATHNAME to use
        it.
      
      o Print out identity when printing logical-hosts.  (This unrelated
        change makes it easier to see that the user's BOGUS logical host
        isn't the same as the BOGUS logical host used in
        *LOGICAL-PATHNAME-DEFAULTS*.

      Fix some issues with two-arg log function. (log 17 10f0), (log 17f0 · 0f17dd30
      rtoy authored
      10), and (log 17 10) returned different single-float results.  I think
      this is allowed by ANSI CL, but I think it's unfortunate.
      
      Therefore, try to apply float contagion to the arguments before
      computing the log function.  Also, if both args are single-floats or
      rationals, we coerce them to double-floats before computing the
      result.  This makes (log 17 10) = (log 17.0 10).
      
      There are other cases still to be considered.

      Port SBCL'S support for detecting when destructive functions (such as · 31ddb605
      rtoy authored
      nreverse) modify constant args and for warning when the result of
      destructive functions is not used.
      
      Detecting modification of constant args is done by adding a new IR1
      transformation that checks that a function is not destructively
      modifying constants or literals.
      
      A new IR1 attribute, important-result, is used to determine if the
      result of a function should be used instead of discarded.  (Note:
      this means some functions are not detected.  This should probably be
      implemented as another transform so the compiler can detect those cases.)
      
      code/error.lisp:
      o Add new condition CONSTANT-MODIFIED.
      
      compiler/fndb.lisp:
      o Note destructive functions that should not modify constant args
      o Note destructive functions whose results should be used.
      
      compiler/ir1opt.lisp:
      o Add new function CHECK-IMPORTANT-RESULT to check if the result is
        used.
      o Update IR1-OPTIMIZE-COMBINATION to check if a function destructively
        modifies constant args or if the result of a destructive function is
        not used.
      
      compiler/knownfun.lisp:
      o Add new IR1 attribute, IMPORTANT-RESULT, to indicate that the result
        of a function should be used.
      o Add new FUNCTION-INFO slot, DESTROYED-CONSTANT-ARGS.  This holds a
        function for computing the constant or literal arguments which are
        destructively modified by the function.
      o Add support functions for DESTROYED-CONSTANT-ARGS functions.

      parse-unix-namestring: · c0715083
      rtoy authored
      o Don't allow a namestring to be parsed as a search-list if a logical
        host with the same host name already exists.  Allowing this causes
        confusing in printing such pathnames because, when read, the logical
        host takes precedence.
      
      unparse-unix-file:
      o Preserve version :NEWEST when printing out logical pathnames.  This
        makes #p"host:foo.bar.newest" readable.

      For all intents and purposes, pathnames with :version nil and :version · f629b245
      rtoy authored
      :newest are equivalent in CMUCL.
      
      src/pathname.lisp:
      o Make EQUAL compare pathnames such that version nil and :newest are
        equal.
      
      src/hash-new.lisp:
      o Adjust sxhash to treat :version nil and :newest the same.  (Version
        :newest is hashed as if it were nil.)
