            * Changed implementation on ALLOCATE-VECTOR on X86:
            ... two VOPs: A-V-ON-HEAP and A-V-ON-STACK;
            ... choice between them is made with LTN-ANALYZEr;
            ... A-V-ON-STACK always fills vector with zeroes (fixes bug
                reported by Brian Downing).

  1. Fixes for OS X 10.4 "Tiger"

    Brian Mastenbrook authored
      * Binaries built on OS X 10.4 will not run on OS X 10.2.8 "Jaguar"
      * Add a . at the end of a gethostbyname test in sb-bsd-sockets to both work around a resolver bug on Tiger and robustify the test
      * Thanks to Gary Byers for the alternate sigreturn bug fix
      * Bump the upcoming version number in NEWS to 0.9.0 (woohoo!)

    Alexey Dejneka authored
            * As suggested by CSR, when (> SAFETY 0) allocate vector on
              stack only when it provably fits in one page.
            * Properly order *POLICY-DEPENDENT-QUALITIES*: later qualities
              may refer earlier.

  3. @nikodemus "oops" -- that wasn't an optimization!

    nikodemus authored
     * don't transform EQL to EQ if either argument is known to
        be a fixnum, as we have backend magic to deal with that. The
        effect of the previous "improvement" was rather horrible
        for bignums. Still apply the transform if the fixnumness is
        in question.

    	Fix bug in scoping of free special declarations. CLHS 3.3.4:
            "The scope of free declarations specifically does not include
            initialization forms for bindings established by the form
            containing the declarations."
            * Add a :BINDING-FORM-P parameter to PROCESS-DECLS. If true,
              return a list of the VARs created by PROCESS-SPECIAL-DECL
              for free bindings instead of adding them into the lexenv
            * PROCESSING-DECLS optionally uses :BINDING-FORM-P and
              binds the list to a supplied variable in the PROCESSING-DECLS
            * Calls to PROCESS-DECLS / PROCESSING-DECLS related to binding
              forms use the above changes.
            * The VAR list is threaded through a bunch of IR1 lambda
              translation utility functions, all of which sooner or later
              end up calling IR1-CONVERT-AUX-BINDINGS.
            * Before IR1-CONVERT-AUX-BINDINGS converts the body, add the
              variables in the list to the lexenv.

            PPC allocate-vector fix, plus OpenMCL buildability ...
            ... write a 0 at the end of the allocated vector to ensure
                all of its pages are unprotected.  Otherwise if one is
                passed off to C (by READ-N-BYTES for example) the GC

  2. improvement for the space reservation mechanism on OS X

    Brian Mastenbrook authored
      * The C runtime is no longer relinked after running nm, which should avoid
        some cases where symbols moved when linking in the read-only space reservation
    	object. This was previously observed as segfaults in target-2 and could be worked
    	around by choosing a different C compiler.
      * Space is now reserved for each of our fixed-address spaces on OS X, currently:
          * read-only space
    	  * static space
    	  * dynamic-1 and dynamic-2 spaces
    	  * linkage table space
    	Should Apple ever decide to move the malloc heap again, none of these spaces will be picked
    	because their virtual memory ranges will have been reserved by the linker.
  3. @nikodemus tweak finalizers, thighten spec further

    nikodemus authored
     * sprinkle WITHOUT-GCING around, so that we won't enter GC while
        holding the lock on finalizer store.
     * specify that finalizers run in an unpredictable dynamic scope and
        must be fully re-entrant. Add a few examples for good measure.
     * add finalizer, weak pointer, and after gc hook documentation to the

         interrupts enabled and all threads[1] running; it is now safe to
         allocate in them as re-entry to GC is possible.
      * put a lock on the global finalizers list, as per Gabor Mellis'
         patch. Gratuitiously change the name of the selfsame global variable
         to flush out anyone diddling with it.
      * tighten the finalizer spec with a note that they may run in any
      * add a stress-test for finalizers.
