fdefn-raw-addr-slot actually hold a tagged pointer instead of the raw
address.  Not sure if this is good or not, but making it like sparc
makes ppc a little easier.

Might need a cross-compile; the 2005-12-1-ppc cross-compile script
works fine.

assembly/ppc/arith.lisp:
o Static functions are now tagged, so need to adjust address before
  branching to them.

compiler/generic/new-genesis.lisp:
o Fill fdefn-raw-addr-slot with the tagged address instead of
  converting to untagged.

compiler/ppc/call.lisp:
o fdefn-raw-addr-slot is tagged, so need to adjust it before branching
  to function.

compiler/ppc/cell.lisp:
o No need to adjust function address before storing it in the
  fdefn-raw-addr-slot.

compiler/ppc/static-fn.lisp:
o Static functions are tagged, so need to adjust address before
  branching to them.

lisp/gc.c:
o Don't need scav_fdefn, because the fdefn is a tagged object now.

lisp/ppc-assem.S:
o Make undefined_tramp and closure_tramp be tagged instead of
  untagged.

lisp/purify.c
o RAW_ADDR_OFFSET is 0 now, like sparc.

by the commit of the NetBSD support, and needed by the upcoming merge of
the OS X/Darwin port.

  - fix a signed/unsigned cast bug that was prevented the
    auto-gc-trigger from functioning correctly when using certain
    dynamic-space sizes (for platforms that don't have an internal gc
    trigger).

  - added a few #include files to avoid compiler warnings

  - changed some #ifdef semantics: DEBUG activates additional
    assertions, and PRINTNOISE activates debugging statements.

preprocessor token.

There is an incorrect gc_assert in lisp/gc.c in the function
from_space_p. The argument is not necessarily a descriptor; it may be
an untagged pointer, in which case the assertion is false. This causes
rebuild to fail on SPARC when GC assertions are enabled.

This observation is due to Daniel Barlow (and is fixed in SBCL).

objects, to avoid falsely pairing with a fixnum.

  of the dynamic space. DYNAMIC_SPACE_SIZE now defines the maximum
  size, and when defined DEFAULT_DYNAMIC_SPACE_SIZE gives the default.

o Increase the maximum dynamic space size for Linux x86 to 1.625GB,
  with the default remaining at 512MB.

o Define the default dynamic space size for FreeBSD x86 to also be 512MB,
  with a maximum of 2GB.

types. Adds storage classes to the backend for these so they can be
stored in registers or on the stack without consing; new primitive
types etc. Also adds (simple-array (complex {single,double}-float))
array types to avoid consing and speed vectors operations.  All
these changes are conditional on the :complex-float feature. More work
is needed to exploit these changes: improving the type dispatch in the
various function; maybe compiler transforms or more VOPs to handle
common functions inline.

required on the MIPS port where the NFP is a descriptor reg. Correct
fix for the sparc is to not have the NFP defined as a BOXED register,
it's defined as a non-descriptor register in compiler/sparc/vm.lisp
and the GC was scavenging it and picking up bad pointers.

(signed-byte 16), (signed-byte 30), (signed-byte 32).  These patches
include the general support and the x86 backend support; more to
follow. The important changes are conditional on the :signed-array
feature so shouldn't affect the source without this feature. This work
has been driven by Raymond Toy.

Size table fix, type_InstanceHeader should be size_boxed.

The scavenge function can be compiled to either directly dispatch to
the scavenge functions, or handle some common cases itself
(pointers/forwarding-pointers, fixnums) only calling the dispatch
functions if necessary. In the second case there was redundant pointer
and forwarding pointer checks in the pointer scavenging functions -
this redundancy has been removed. Now define DIRECT_SCAV to have
scavenge directly call the scavenge functions, else it handles some
common cases itself (which gives better performance); the appropriate
versions of the pointer scavenging functions will be compiled.
