    1.0.30.54: Fix a cross-compiler leak in specialized %unary-truncate

    csrhodes authored
    Don't use host values of most-fooative fixnum.  (Also expand on the
    comment about using an exclusive test for floats within the fixnum
    range)

    The alignment restrictions on movaps for moving a pair of single floats
    are too strict; use movq instead.  (From Paul Khuong)

    1.0.30.51: fix for COERCE compilation regression

    csrhodes authored
    Code of the form
      (defun foo (x)
        (declare (type simple-vector x))
        (coerce x '(vector (unsigned-byte 8))))
    should not cause a full WARNING, but with the new COERCE transforms,
    expanded into one of those IFs where one branch is dead, but the
    compiler couldn't prove it.
    
    Define a whole heap of new backend type predicates for all specialized
    vectors, generalizing VECTOR-T-P.  (Some specialized vectors are
    implemented using widetags, and so are excluded from these new
    definitions).

    1.0.30.49: delete-file behaviour reversal

    csrhodes authored
    In the 1.0.29.x series, DELETE-FILE started deleting the truename of the
    given pathname designator (rather than the pathname itself), meaning
    that symlinks could no longer be deleted.  Revert back to the historical
    behaviour.  (Noted on sbcl-devel by Luis Oliveira 2009-08-18.)
    
    Although the behaviour hasn't changed recently, there's a similar issue
    in RENAME-FILE, but that operator has such bizarre behaviour anyway it
    might be worth just letting sleeping pathname functions lie.

    1.0.30.48: utf-8 simple-array-nil correctness

    csrhodes authored
    If an empty range of a simple-array-nil is requested for conversion, we
    should return an empty octet sequence, not blow up.

    x86 sap fixes

    csrhodes authored
    The sap-ref-with-offset stuff was wrong in that the displacement was
    multiplied by a notional element size, rather than being uniformly
    treated as a number of bytes.  Mostly this codepath wasn't exposed at
    all (other than with sap-ref-8, which worked by "accident"), but
    attempts to implement UTF-16, which requires (sap-ref-16 sap (+ offset
    2)), showed up the problem.

    1.0.30.46: SB-INTROSPECT test adjustment

    1.0.30.45: various pretty-printing improvements

    nikodemus authored
     Patch by Tobias Rittweiler:
    
     * Add a PPRINT-DECLARE which a) makes sure that (DECLARE (FUNCTION
       F)) is not printed as (DECLARE #'F), and b) places each declaration
       specifier on its own line. Also used for DECLAIM.
    
     * Better pprint SETQ forms which assign to multiple variables. At the
       moment it's printed like
    
        (SETQ FOO
                (FROB-FOO 0 1 2 3 4 5 6 7 8 9)
              QUUX
                (FROB-QUUX 9 8 7 6 5 4 3 2 1 0))
    
       With the patch it's indented like
    
        (SETQ FOO (FROB-FOO 0 1 2 3 4 5 6 7 8 9)
              QUUX (FROB-QUUX 9 8 7 6 5 4 3 2 1 0))
    
       It uses the former indentation style if the value (e.g. the
       "(FROB-FOO ...)") does not fit on a single line.
    
       This also affects PSETQ, SETF, PSETF.
    
     * Add pprint entry for SB-INT:DX-FLET because there are CL macros
       which expand to that.
    
     * Fix typo in *LOOP-SEPARATING-CLAUSES*; I mistakenly put WHERE
       instead of WITH in it.
    
     * Fix PPRINT-IF to make sure that the predicate is always printed
       right after the IF. The current definition may occassionally print
       an IF form like
    
       (IF
        (PREDICATE)
        (THEN)
        (ELSE))
    
     * Some small refactoring work:
    
       - Use PPRINT-LINEAR, and PPRINT-FILL instead of equivalent, but
         hairy FORMAT calls.
    
       - Add PPRINT-SPREAD-FUN-CALL which is the common subtrate of
         pretty-printing simple LOOP forms, and DECLARE forms.

    1.0.30.44: DECODE-FLOAT and INTEGER-DECODE-FOAT are not flushable

    nikodemus authored
     ...as they should signal an error for non-floats in safe code,
     and hence UNSAFELY-FLUSHABLE.
    
     Ditto for FLOAT-SIGN, FLOAT-RADIX, FLOAT-DIGITS, and FLOAT-PRECISION,
     though for some reason Python seemed unwilling to delete these calls
     despite them being marked as flushable as well.

    1.0.30.40: faster SLOT-VALUE on structures

    nikodemus authored
     * Replace the SLOT-VALUE and SET-SLOT-VALUE compiler macros
       with deftransforms once PCL has been built, and if the type
       is known to be a structure and the slot name maps cleanly
       to an accessor we can use it.

    1.0.30.39: SB-INTROSPECT:ALLOCATION-INFORMATION test adjustment

    nikodemus authored
     * Ignore the :LARGE property on PPC, where is seems to bounce
       back and forth. Reported by Bruce O'Neel.
    
       (This is not a real fix, of course: the question of _why_
       PPC sometimes has (or thinks it has) #'CONS on a large
       object page remains.)

    1.0.30.38: faster TRUNCATE on floats

    nikodemus authored
     * Specialized %UNARY-TRUNCATE/SINGLE-FLOAT and
       %UNARY-TRUNCATE/DOUBLE-FLOAT.
    
     * Explicit coercions to appropriate float types in the TRUNCATE
       transforms. This gets rid of generic arithmetic in the general case
       (Python is reluctant to insert explicit integer-tofloat coercions
       for integers of unknown range due to precision issues.)
    
     * Since COERCE (and %SINGLE-FLOAT and %DOUBLE-FLOAT) are not
       flushable, take core not to generate leftover code in the TRUNCATE
       transform when the result lvar has a single-value type.
    
     * Rename %UNARY-TRUNCATE float VOPs, so that transforming to a
       specialized floating point version doesn't make use unable to
       implement it directly as a VOP when the range of the float is
       sufficiently constrained.

    1.0.30.35: turn SB-INTROSPECT into an ASDF system

     * I at least am starting to find myself having to insert
    
          (EVAL-WHEN (...) (REQUIRE :SB-INTROSPECT))
    
       in too many places. This may be a sign that things aught to be in
       SB-EXT instead, but ASDFication seems like a logical next step.
    
       ...arguably all contribs but ASDF itself should be ASDF systems.

    1.0.30.33: failed aver in %ALLOCATE-CLOSURES IR2 conversion

    nikodemus authored
     Patch by Larry D'Anna. He explains:
    
       This snippit
          (labels ((K (&optional x) #'k)))
       fails with failed AVER: (XEP-P XEP), in %ALLOCATE-CLOSURES-IR2-CONVERT-OPTIMIZER
    
       The problem is that it's trying to allocate a closure for the XEP
       for K, but K has been deleted because nothing references K except
       itself. %ALLOCATE-CLOSURES-IR2-CONVERT-OPTIMIZER already skips any
       leafs that lacks a XEP. This patch makes it also skip leafs who's
       XEPs have been deleted.

    1.0.30.26: fix failing AVER in CONVERT-MV-CALL

    nikodemus authored
     See https://bugs.launchpad.net/sbcl/+bug/392203
    
     Patch by Larry D'Anna.
    
     His comments:
    
       Ever since Spice Lisp, convert-mv-call had returned without doing
       anything if (functional-entry-fun fun) is not null, ie if fun
       possesses a XEP. 0.8.5.5 replaces this criterion with "if the last
       optional entry has references", and signals an error if the last
       optional entry has no references and the XEP exists.
    
       I can't know exactly what Alexy was thinking when he put the aver
       in, but I can guess: If the XEP exists it should contain a
       reference to the last entry point, so if the last entry point has
       no refs and a XEP exists something went wrong. However, if the
       number of required + optional arguments is 0, then XEP doesn't need
       the "last" entry point, it can always use the "more" entry point
       instead, which is exactly what seems to have happened in this case.
    
       This patch combines the two conditions. convert-mv-call will return
       without action if *either* a XEP exists, *or* the last optional
       entry has references."

    1.0.30.23: adjust OpenBSD address spaces on x86

    nikodemus authored
     * Patch by Josh Elsasser. He says:
    
       "The current address space locations for x86 OpenBSD are adequate,
       but could still be better chosen. The only real problem with the
       current addresses is that the default dynamic space size is larger
       than the default data size resource limit, which means that sbcl
       will not run without some tweaking. Attached is a patch to lower
       the dynamic space size, as well as move all spaces to locations
       which I suspect may prove more future-proof against OpenBSD
       changes. The patch also greatly expands the OpenBSD comment. I
       apologize for the verbosity, but the address space layout on
       OpenBSD/i386 is quite complex and I wanted to record the details
       before I forgot (again)."
    
       Committing untested, as I don't have an OpenBSD system available.
