    	Whoops.  NEWS asserts that LOAD copes with :external-format
    	arguments.  Better make sure that the compiler is aware of that
    	too.

    Alexey Dejneka authored
            * Fix MISC.535: CONSTANT-LVAR-P looks through CASTs.
            * Workaround lack of recursion recognition in XC for
              PRINCIPAL-LVAR-USE.

    jsnell authored
            Increment +fasl-file-version+. It just wouldn't feel like a real
            SBCL release without invalidating the fasls.
    
            * Some FFI-related fasls became incompatible at about 0.8.19.26.
              Probable cause: "lazy alien resolution improvements".

            * Fix MISC.527: DEFTRANSFORM for BIT-AND and similar for
              vectors use (ARRAY-DIMENSION v 0) instead if LENGTH to get
              the full vector size.

    0.8.19.33: fix inspection of specialized arrays

    nikodemus authored
               Patch by Simon Alexander on sbcl-devel 2005-02-19.
    
               Note to self: it seems that we don't currently have
               _any_ tests for the inspector. Make it not so, someday
               soon for preference.

    	x86-64 floating point improvements:
            * Optimization: fewer moves on floating point add/sub/mul/div.
              Only use a temporary xmm register if absolutely needed.
    	* Optimization: When restoring xmm15 to zero after a c-call,
              use xorpd instead of a temporary register and movq.
            * Replace broken x87 FLOATING-POINT-MODES and SET-FLOATING-POINT-MODES
              with SSE code that uses the mxcsr control register.
            * Fix movd / movq from a xmm register to a gp register.
            * Add new instructions: ldmxcsr, stmxcsr

    0.8.19.30: less COMPILE-FILE verbosity

    nikodemus authored
               First stab at fixing bug #7. To get output approximately as
               verbose as the old behaviour use :TOP-LEVEL-FORMS as the
               value of the :PRINT option to COMPILE-FILE.
    
               Note: Giving users control over the way things are printed
               via *COMPILER-PRINT-VARIABLE-ALIST* is OTOH a good thing,
               but it also seems to be used for ratheer diverse things,
               and people could reasonably want to customize them
               separately. Gah.
    
               Also list x86/FreeBSD4 as "expected to pass tests" in
               make.sh output, as that seems to be the case.

    0.8.19.26: fix bignum printing:

    nikodemus authored
                * algorithm by Harald Hanche-Olsen.
                * good: less memory-intensive, faster for smallish
                   bignums.
                * bad: more CPU-intensive for large eg. 2^1000000)
                   bignums, around order of 2^10000000 becoming essentially
                   unprintable.
    
               lazy alien resolution improvement:
                * resolve undefined functions to the address of
                   undefined_alien_function instead of the guard
                   page to work around the bus error on ppc/darwin.
                * also buys us discrimination between undefined alien
                   variables and functions (on all platforms).
    
               note ppc/darwin problems revealed by tests/ in BUGS, and disable
               those tests:
                * floating-point overflow not signalled
                * type-error from sb-profile:report
                * bit-and with huge bit-vectors fails with a lost
                   gc-invariant (maybe a general cheney-gc problem?)
    
                => All tests now pass on ppc/darwin, note this in the message
                   at the end of make.sh, marking x86/Linux and ppc/Darwin
                   as platforms where all tests are supposed to pass.

            Fix ansi-test failures related to pretty-printing backquoted forms
            when *PRINT-CIRCLE* is true. Print the ",@" and ",." tokens with
            WRITE-STRING instead of PRINC to prevent circularity detection
            from applying to them.

    jsnell authored
            Optimize float/fixnum comparisons, primarily for the benefit
            of McCLIM. If the fixnum's value is in a range where it's
            guaranteed to have an exact float representation, coerce it to
            a float and do a float comparison. Otherwise fall back to the
            old behaviour of rationalizing the float.
