Update to SBCL 1.3.21

New in version 1.3.21

 - minor incompatible change: the CLOBBER-IT restart for defstruct
   redefintion has been removed after a 15 year deprecation cycle.
   Use the new name, RECKLESSLY-CONTINUE. Note also that this restart
   is hidden if deemed unsafe due to altered placement of untagged slots
   in the structure.
 - enhancement: the assignment of -DSBCL_PREFIX= in src/runtime/GNUmakefile
   can be removed as a local patch, which results in an sbcl executable
   that finds its core file relative to itself by looking in "../lib/sbcl".
 - enhancement: backends using the generational GC are able to relocate
   dynamic space anywhere the operating system places it. This feature
   can be disabled by removing :relocatable-heap from the build configuration.
   Not supported on Windows.
 - enhancement: DEFMETHOD no longer signals IMPLICIT-GENERIC-FUNCTION-WARNING.
 - enhancement: better type conflict detection for high order functions,
   e.g. (find x "123" :test #'=)
 - enhancement: the tabular output of ROOM is aligned dynamically,
   preventing misaligned tables for larger sizes or counts.
 - enhancement: ROOM reports on immobile space if applicable.
 - optimization: optimized external-format routines.
 - bug fix: SB-INTROSPECT:ALLOCATION-INFORMATION returns :IMMOBILE
   instead of :FOREIGN for objects in immobile space.
 - bug fix: dotted lists in special forms and function call forms signal
   an appropriate error
 - bug fix: EQUALP hash tables with pathname keys now ignore internal slots.
   (#1712944, reported by Jason Miller)

New in version 1.3.20

 - minor incompatible change: DEF{GENERIC,METHOD} no longer accept
   some illegal lambda lists such as (defgeneric bar (foo &key foo))
   or (defgeneric baz (t)) that were accepted before.
 - optimization: a valueless &AUX binding in a BOA constructor does not
   force all slots reads in safe code to perform a full type check.
 - optimization: ATOMIC-PUSH and ATOMIC-POP generate better code
 - bug fix: the low-level debugger would erroneously print - or not print
   as the case may be - "(bad-address)" for some objects depending whether
   the --dynamic-space-size argument was used at Lisp startup
 - bug fix: a DEFCONSTANT with a non non-eql-comparable object as the value
   could cause miscompilation if that constant appeared as the default
   expression for an &OPTIONAL binding
 - bug fix: generic function lambda lists are now checked for repeated
   and otherwise illegal entries. (#1704114)
 - bug fix: setting gencgc_verbose = 1 could cause deadlock in fprintf()
   depending on the platform's stdio implementation. The relevant code
   has been changed to use snprintf() and write() instead.

New in version 1.3.19

 - enhancement: specialized arrays can be printed readably without using
   *read-eval*
 - enhancement: SB-DEBUG:PRINT-BACKTRACE truncates huge string arguments.
   The full string remains available for inspection via (SB-DEBUG:ARG).
 - bug fix: backtracing from several threads at once could fail
 - bug fix: floating-point infinities could not be used as keys in EQUALP
   hash tables. (#1696274)
 - bug fix: random sb-fasteval failures. (#1642708)
 - bug fix: align the stack in callback wrappers to defend against C compiler
   over-aggressive use of SIMD. (#1697528)
 - bug fix: don't try to find the class when reporting that a class does not
   exist for a primitive type. (#1697226)

Update to SBCL 1.3.18

changes in sbcl-1.3.18 relative to sbcl-1.3.17:
  * minor incompatible change: existing values of CFLAGS, ASFLAGS,
    CPPFLAGS, and LINKFLAGS will be incorporated into C compiler
    invocations when building from source.
  * minor incompatible change: the result of WRITE-TO-STRING may be
    a BASE-STRING if all characters written are of type BASE-CHAR.
  * minor incompatible change: the broadcast stream with no output
    streams is a singleton object. That object satisfies OPEN-STREAM-P
    regardless of how many times CLOSE is invoked on it.
  * enhancement: x86[-64] backends contain an experimental feature
    which aids in demonstrating reachability of any object starting
    from a tenured object or a thread stack by producing a proof
    as a sequence of pointers to follow.
    The file "tests/traceroot.test.sh" contains an example usage.
  * enhancement: if the alien symbol "gc_coalesce_string_literals" is
    set to 1 prior to SAVE-LISP-AND-DIE, then similar string constants
    loaded from different fasl files may be collapsed to one object.
    If the variable is set to 2, then additionally strings which are
    STRING= in code resulting from COMPILE can be coalesced.
    For instance, two functions returning the literal string "HI"
    might return EQ strings after collapsing, which may be undesired
    in a particular use. The flag pertains to gencgc only.
  * enhancement: SXHASH values on pathnames are better distributed
  * bug fix: MAKE-PATHNAME removes empty strings as components of a
    directory, as is permitted: "Whenever a pathname is constructed
    the components may be canonicalized if appropriate."
  * optimization: various printer and FORMAT performance enhancements.
  * bug fix: GET-FOREGROUND no longer fails in case all other interactive
    threads exit (lp#1682671, reported by Syll)
  * bug fix: RELEASE-FOREGROUND always removes the current thread from the
    list of interactive threads. (lp#1682867, reported by Syll)

Log message:
Update to SBCL 1.3.17

changes in sbcl-1.3.17 relative to sbcl-1.3.16:
  * enhancement: memory overhead from the garbage collector's metadata
    is reduced on 64-bit architectures; no change for 32-bit.
  * enhancement: further garbage collector speedups affecting
    pinned objects on conservative backends, and simple-vectors.
  * enhancement: on Linux a custom handler for SIGSEGV can be called
    for page faults outside of dynamic space by changing the C symbol
    "sbcl_fallback_sigsegv_handler".
  * bug fix: sb-cover does not lose source positions for AND/OR/COND.
  * bug fix: random disassembler failures. (lp#1527931)
  * The bundled sb-md5 contrib has been updated to release 2.0.4
    which is licensed under Creative Commons CC0 per author's statement
    https://github.com/pmai/md5/commit/fd134e71b71a10ab78905833a7cb9d4d6817c589

Update to SBCL 1.3.16

changes in sbcl-1.3.16 relative to sbcl-1.3.15:
  * optimization: various small tweaks give around 5% faster garbage
    collection
  * bug fix: better detection of when an impossible code path does
    not need a warning.  (lp#1668619)
  * bug fix: stronger attempts to disable position-independent
    executable building.  (lp#1668986, patch from Mark Wright)
  * bug fix: OPEN :IF-EXISTS NIL signalled a condition on Windows.
    (lp#1674437, reported by Jan Idzikowski)

changes in sbcl-1.3.15 relative to sbcl-1.3.14:
  * minor incompatible change: the reader will when feasible create
    new symbols using a BASE-STRING for the print name.  Additionally,
    string literals can favor the base-string type if desired, though
    the default is to always return UTF-32 strings for compatibility.
    A preference for base-string does not disable reading Unicode.
    The choice is controlled via (SETF READTABLE-BASE-CHAR-PREFERENCE).
    If Unicode was disabled at build time, this setting does nothing.
  * enhancement: SBCL generates more debug information by default.
  * enhancement: type errors provide context information, such as which
    variable is being bound, which slot of which structure is being set.
  * enhancement: if #+immobile-symbols is in build-time *FEATURES* (not
    enabled by default), then symbols will never be moved in memory
    except by SAVE-LISP-AND-DIE. Immobility has helpful implications for
    code generation as well as interaction with foreign routines.
    This feature can only be enabled if #+immobile-space is enabled.
  * enhancement: undefined function errors can be restarted on x86-64, to
    either retry calling the function again or call a user supplied function.
  * enhancement: sb-ext:restrict-compiler-policy accepts an upper bound in
    addition to a lower bound.
  * enhancement: #+immobile-code improves the speed of function calling.
    Some delay may be noticed when redefining an existing function
    from a saved core file however.
  * defaults change: sb-ext:*disassemble-annotate* default to NIL, due to its
    poor reliability.
  * new feature: SB-LINKABLE-RUNTIME, allowing linking with extra object
    files to help with delivery of executables.  (Thanks to Francois-Rene
    Rideau)
  * bug fix: data race in GENTEMP fixed - it can no longer return the
    same interned symbol to multiple threads if called concurrently
  * bug fix: interrupting LOADing of FASLs does not leave functions without
    source locations. (lp#540276)
  * bug fix: DYNAMIC-EXTENT-declared results of NOTINLINE local functions were
    treated as if they were actually stack allocated (lp#1659964)
  * bug fix: correctly handle the case of a non-local exit within a function
    terminating the extent of dynamic-extent, dynamic-bound variables in the
    presence of multiple-values (lp#1655011)
  * bug fix: handling of SB-SYS:WITH-PINNED-OBJECTS in the interpreters (both
    sb-eval and sb-fasteval) now actually pins objects on gencgc.
  * bug fix: AVX registers are preserved during exceptions on x86-64 macOS.
  * bug fix: (directory "SOMETHING/*/**/MORE") is no longer equivalent to
    (directory "SOMETHING/**/MORE")
  * bug fix: better console IO on Windows (lp#1660906)

changes in sbcl-1.3.14 relative to sbcl-1.3.13:
  * minor incompatible change: the SB-PCL walker no longer recognizes
    macros expanding into a DECLARE expression. This is not a language change,
    since ANSI forbids such usage (X3J13 issue DECLARE-MACROS:FLUSH).
  * enhancement: for several macros such as MULTIPLE-VALUE-{BIND,SETQ}, COND,
    DO{,*,LIST}, {RESTART,HANDLER}-{BIND,CASE}, *CASE, conditions signaled
    during macroexpansion point to the form that caused the problem more
    accurately.
  * enhancement: the "--noinform" command-line option inhibits output from
    save-lisp-and-die in addition to removing the startup banner.
  * bug fix: PROCESS-KILL failed to return errno if the system call failed
  * optimization: slightly more comprehensive treatment of the keyword
    arguments to MAKE-ARRAY in compiler transformations.

changes in sbcl-1.3.13 relative to sbcl-1.3.12:
  * enhancement: SET triggers package locks on undefined variables.
    (lp#1645152)
  * enhancement: new Windows specific option to run-program, :escape-arguments
    (lp#1503496)
  * enhancement: recompiling a MAKE-INSTANCE form with an initarg :INITARG
    CONSTANT where CONSTANT names a constant variable picks up the new value
    of CONSTANT in case it has been redefined. (lp#1644944)
  * optimization: faster TYPEP on undefined at compile-time types and upcoming
    class definitions. (lp#1082967)
  * optimization: memory consumption of each STANDARD-OBJECT instance is
    reduced by 2 words if the compact-instance-header feature is enabled.
  * optimization: CONDITION instances are quicker to allocate.
  * optimization: unoptimized calls to FILL on specialized vectors are now
    just as fast as T vectors.
  * bug fix: get-timezone returns corret DST on 64-bit Windows. (lp#1641058)
  * bug fix: cross reference information in fasls is no longer incompatible
    between different cores (lp#1648186)

Update to SBCL 1.3.12

New in version 1.3.12

 * enhancement: on x86-64, compiled functions loaded from fasl
   files can not be moved, but can be freed, by GC.
   Additionally, COMPILE will produce immobile code
   if SB-C::*COMPILE-TO-MEMORY-SPACE* is set to :IMMOBILE.
   (Caution: the flag is experimental and subject to change.)
   The benefits are better physical separation of code from
   data, and potentially easier examination of live images by
   external tools.
 * enhancement: the docstring for SAVE-LISP-AND-DIE has been
   amended to say that the :ROOT-STRUCTURES parameter is not
   meaningless on gencgc, depending on the platform.
 * bug fix: calling a named function (e.g. a DEFUN) concurrently
   with redefining that same function could lead to execution of
   random bytes.
 * bug fix: yes-or-no-p accepts formatter functions (#1639490)
 * bug fix: better handling of exceptions on macOS.

New in version 1.3.11

 * minor incompatible change: SB-EXT:*INTEXP-MAXIMUM-EXPONENT*
   is removed.
 * enhancement: TRACE ... :REPORT {TRACE,NIL} now work as
   advertised in the documentation string (based on patch by
   Patrick Stein)
 * enhancement: support unboxed signed-word structure slots on
   x86, x86-64 and ARM64. (#377616)
 * optimization: faster logical bit-array operations on
   multidimensional arrays.
 * optimization: better GC performance in the presence of many
   threads. (patch by Ilya Perminov, #1339924)
 * optimization: multiple-value-call is optimized with multiple
   argument forms, not just one. (#753803)
 * bug fix: MAKE-ALIEN-STRING returns the number of allocated
   bytes as a second value as advertised (reported by Johann
   'Myrkraverk' Oskarsson)
 * bug fix: when TO-READTABLE is supplied to COPY-READTABLE, it
   will contain only the macros in FROM-READTABLE and no others.
   (#1631506)
 * enhancement: gencgc has been modified for x86-64 on Linux and
   macOS to a support mark-and-sweep as well as the traditional
   copying strategy. It is conceivable that some applications
   might be adversely affected. Please see ':immobile-space' in
   'base-target-features.lisp-expr' for further details, and
   possible reasons to disable this feature.
 * enhancement: x86-64 supports shrinking the fixed overhead in
   a structure from 2 words to 1 word, reducing memory
   consumption in applications which create many small
   structures.

Log message:
Update to SBCL 1.3.10.

New in version 1.3.10

 * enhancement: more compact low-level error signaling code
 * enhancement: more compact encoding of cross-reference information
 * optimization: faster out of line fixnum-float comparisons.
 * optimization: filling a known simple-vector with a constant value is about
   as fast in unoptimized code as in code compiled with (SPEED 3), and the
   x86-64 implementation is able to use SSE instructions.
 * bug fix: correctly handle the case of a non-local exit within a function
   terminating the extent of dynamic-extent functions and variables in the
   presence of multiple-values (#1563127)
 * bug fix: restore builds on the latest OSX with the latest Xcode (#1470996)

New in version 1.3.9

New in version 1.3.8

 * minor incompatible change: the system now understands that the CONDITION
   type is disjoint with many other system types.
 * minor incompatible change: argument types in condition report functions are
   now declared (in combination with the above change, this can result in
   early detection of erroneous code).
 * enhancement: simple arrays of any rank can be stack-allocated on platforms
   supporting stack allocation of vectors.

     + ECASE/ETYPECASE;
     + ARRAY-DIMENSIONS;
     + ARRAY-TOTAL-SIZE;
     + REMOVE, REMOVE-DUPLICATES, DELETE and DELETE-DUPLICATES on lists.

New in version 1.3.6

 * bug fix: do not insert conditional newlines in print-unreadable-object
   (#1398290). This reverses a change made in #488979 which reversed a fix
   advertised in release 0.8.14 to pass the GCL ANSI Test Suite.
 * bug fix: constant negative rotations of 32-bit quantities are compiled
   correctly on x86-64 and arm. (#1586614, reported by Guillaume Le Vaillant)
