Update to SBCL 1.0.38

changes in sbcl-1.0.38 relative to sbcl-1.0.37:

  * incompatible change: Thread names are now restricted to SIMPLE-STRINGs
    like for any other thread-related datastructure, MUTEX, etc. (lp#547095)
  * deprecation: the SB-QUEUE contrib was merged into the SB-CONCURRENCY
    contrib module. New code should depend on SB-CONCURRENCY, not SB-QUEUE.
  * deprecation: SB-THEAD:GET-MUTEX was deprecated in favor of
    SB-THREAD:GRAB-MUTEX.
  * new contributed module: SB-CONCURRENCY is a new contrib; it's supposed to
    contain additional data structures and tools for concurrent programming;
    at the moment it contains a lock-free queue, and a lock-free mailbox
    implementation.
  * new feature: added SB-THREAD:GRAB-MUTEX; it's like the now deprecated
    GET-MUTEX but takes &key rather than &optional parameters.  Also added
    :TIMEOUT argument to GRAB-MUTEX on non-sb-lutex platforms like Linux and
    BSD.
  * new feature: added SB-THREAD:TRY-SEMAPHORE, a non-blocking variant of
    SB-THREAD:WAIT-ON-SEMAPHORE.
  * new feature: SB-EXT:ATOMIC-DECF has been added as a companion to
    SB-EXT:ATOMIC-INCF.
  * new feature: a CANCEL-DEADLINE is associated with DEADLINE-TIMEOUT
    conditions to defer the deadline for forever.
  * enhancement: *STANDARD-OUTPUT*, *STANDARD-INPUT*, and *ERROR-OUTPUT* are
    now bivalent.
  * enhancement: errors from NO-APPLICABLE-METHOD and
    NO-PRIMARY-METHOD now have a RETRY restart available to retry the
    generic function call.
  * enhancement: SB-BSD-SOCKET improvements
    ** sockets and socket streams now have a more informative printed
       representation based on the corresponding SOCKET-NAME and
       SOCKET-PEERNAME.
    ** SOCKET-MAKE-STREAM once more supports the :AUTO-CLOSE option.
       (lp#540413)
    ** SOCKET-CLOSE now accepts :ABORT argument, which is passed on to
       CL:CLOSE when appropriate, and no longer disassociates the stream
       from the socket if close failed. (lp#543951)
  * improvements to the instrumenting profiler
    ** new feature: report per-function GC overhead. (thanks to John Fremlin)
    ** optimization: counters no longer use locks for the overflow mode.
    ** bug fix: whenever a profiling counter wrapped into overflow mode, it
       incurred an off-by-one miscount.
  * enhancement: improved MAKE-HASH-TABLE documentation (lp#543473)
  * enhancement: improved DEFMETHOD pretty-printing.
  * enhancement: perform range reduction when arguments are too large for
    x87's transcendentals (instead of returning 0). (lp#327192)
  * enhancement: eliminate some spurious TYPE-WARNINGs. Should help with
    some of CL-PPCRE's macros. (lp#570079)
  * enhancement: our machine code is slightly less hostile to valgrind on
    x86-64.
  * enhancement: up-to-date versions of NetBSD-current are supported.  (Thanks
    to Robert Swindells and Aleksej Saushev)
  * bug fix: correct restart text for the continuable error in MAKE-PACKAGE.
  * bug fix: a rare case of startup-time page table corruption.
  * bug fix: a semaphore with multiple waiters and some of them unwinding due
    to timeouts could be left in an inconsistent state.
  * bug fix: fix typo in "Reporting Bugs" section of the manual (lp#520366)
  * bug fix: misoptimization of multiplication by one in
    (SB-C::FLOAT-ACCURACY 0) policies.
  * bug fix: miscounts in SB-PROFILE.
  * bug fix: Fix lost wakeup bug between SB-THREAD:CONDITION-WAIT and
    CONDITION-NOTIFY on Linux. See threads "lost wakeup in condition-wait /
    condition-notify" (Feb 2010) and "Condition-Wait, Deadline handler, waking
    up itself" (March 2010) for further details.
  * bug fix: allow forward FIND and POSITION on lists to elide checking :END
    against length of the list if the element is found before the specified
    END is reached. (thanks to Alec Berryman, lp#554385)
  * bug fix: errors signalled during package graph modification no longer
    block FIND-SYMBOL and FIND-PACKAGE in other threads. (lp#511072)
  * bug fix: SB-POSIX build was broken when SBCL was compiled without the
    :SB-DOC feature. (lp#552564)
  * bug fix: SB-INTROSPECT build issues on GENGC/PPC. (lp#490490)
  * bug fix: more robust runtime executable path detection. (lp#375549)
  * bug fix: GCD always returns positive values. (lp#413680)
  * bug fix: Converting division to multiplication by reciprocal handles
    denormals.
  * bug fix: We were too eager in eliding range reduction tests on x87.
    The maximal magnitude is 2^63, not 2^64.
  * bug fix: Transforms for TRUNCATE don't die when the result is completely
    ignored anymore.
  * bug fix: Maybe restore buildability on Alpha.
  * bug fix: READ-BYTE isn't inline anymore, fixing weird streams failures.
    (lp#569404)
  * bug fix: RANDOM-STATE can be printed readably again.
  * bug fix: Unreadable objects were sometimes printed like #<\nFoo>.
  * bug fix: Using EQL with non-constant values of constant type (e.g. EQL
    types) could result in type mismatches during compilation.


changes in sbcl-1.0.37 relative to sbcl-1.0.36:

  * enhancement: Backtrace from THROW to uncaught tag on x86oids now shows
    stack frame thrown from.
  * enhancement: WITH-COMPILATION-UNIT :POLICY allows restricting changes to
    compiler optimization qualities inside dynamic extent of its body.
  * enhancement: LOAD-LOGICAL-PATHNAME-TRANSLATIONS can be used to load
    translations from SYS:SITE;<HOST>.TRANSLATIONS.NEWEST (thanks to Michael
    Weber)
  * optimization: SLOT-VALUE and (SETF SLOT-VALUE) take advantage of
    constraint propgation, allowing better compilation eg. when used to
    access structures with WITH-SLOTS. (lp#520366)
  * optimization: the compiler is now more aware of the type of the underlying
    storage vector for multidimensional simple arrays resulting in better code
    for accessing such arrays.
  * optimization: passing NIL as the environment argument to TYPEP no longer
    inhibits optimizing it. (lp#309788)
  * optimization: more efficient register usage when handling single-float
    arguments on x86-64. (thanks to Lutz Euler)
  * optimization: ADJUST-ARRAY and STABLE-SORT on vectors no longer use
    pre-allocated temporary vectors. (lp#496249)
  * bug fix: Fix compiler error involving MAKE-ARRAY and IF forms
    in :INITIAL-CONTENTS. (lp#523612)
  * bug fix: FUNCTION-LAMBDA-EXPRESSION lost declarations from interpreted
    functions. (lp#524707)
  * bug fix: bogus style warnings from certain (SETF SLOT-VALUE) and
    WITH-SLOTS usages during compilation.
  * bug fix: SB-C::CLASS-INFO now prints correctly. (lp#514762)
  * enhancement: Can now build with ud2 instead of int3 as trap instruction on
    all x86oid platforms with :UD2-BREAKPOINTS target feature.
  * bug fix: Breakpoints now work when using ud2 instead of int3 as trap
    instruction (tested on x86oid linux with ud2-breakpoints).
  * bug fix: slam.sh now works on win32.
  * bug fix: better differences of numeric types. (lp#309124)
  * bug fix: arrays declared intersection and union types can have their
    upgraded element type derived. (lp#316078)

    threads started during profiling. (lp#472499)
  * bug fix: SB-INTROSPECT test failure when building without SB-EVAL feature.
    (lp#535658)
  * bug fix: SB-CLTL2:DECLARATION-INFORMATION did not take
    SB-EXT:RESTRICT-COMPILER-POLICY into account. (lp#313337)
  * bug fix: Comma inside a backquoted array or structure resulted in nonsense
    values instead of signaling an error. (lp#309093)
  * bug fix: Spurious unused variable warning in a DEFSTRUCT edge case.
    (lp#528807)
  * bug fix: More consistent warnings and notes for ignored DYNAMIC-EXTENT
    declarations (lp#497321)
  * bug fix: FIND and POSITION on lists did not check sequence bounds properly
    and failed to detect circular lists (lp#452008)
  * bug fix: leakage from ~/.asdf-install into the ASDf-INSTALL contrib build
    (lp#538974)
  * bug fix: LOOP OF-TYPE VECTOR compile-time error. (lp#540186)
  * bug fix: SIGNAL SB-SYS:INTERACTIVE-INTERRUPT before entering the debugger
    due to it, so that handlers can run.
  * bug fix: reparsing undefined types if they have become defined since
    parsing. (lp#309128)

    &REST and &KEY in lambda-list caused miscompilation (lp#458354)
  * bug fix: WHO-CALLS information for source-transformed and compiler-macro
    expanded calls (lp#542174)
