Make ppc port look a little more like sparc by making
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.

o Static functions are now tagged, so need to adjust address before
  branching to them.

o Fill fdefn-raw-addr-slot with the tagged address instead of
  converting to untagged.

o fdefn-raw-addr-slot is tagged, so need to adjust it before branching
  to function.

o No need to adjust function address before storing it in the

o Static functions are tagged, so need to adjust address before
  branching to them.

o Don't need scav_fdefn, because the fdefn is a tagged object now.

o Make undefined_tramp and closure_tramp be tagged instead of

o RAW_ADDR_OFFSET is 0 now, like sparc.

The boxed register reg_FDEFN is r10, but r10 is one of the registers
used in the C calling convention, so it's a bad idea to have reg_FDEFN
be r10.

So, make r10 be the new unboxed register reg_NL7 and replace reg_L2
with reg_FDEFN.  (I was too lazy to renumber all registers, and I
don't think it matters where reg_FDEFN is.)

A simple cross-compile is needed.  Use boot-2005-12-1-ppc.lisp for the
cross-compile script.

o Make old FDEFN be the new unboxed register NL7.
o Rename L2 to be FDEFN, removing L2 complete.

o reg_L2 no longer exists, so don't use it.

o Make the corresponding changes here that were made in vm.lisp.

o Simple cross-compile script for this change.

Change ## to the traditional /**/ so that we can compile CMUCL on
Tiger (10.4) with gcc (4.x) or Jaguar (10.2) gcc (3.x).  Not the best
solution, but I think gcc 4 doesn't handle ## the same as gcc 3.  But
this allows using the default gcc on both platforms to compile CMUCL.

Checkin the current code for gencgc.  This is a basic port of sparc
gencgc for ppc.  This is not yet functional.  Allocation seems to
work, but GC does not.  We're just making a checkpoint now.

o Update allocation macro to support gencgc.  Need a temp-tn as a
  scratch register for inline allocation.

o Update for new allocation macro for gencgc.

o Define *scavenge-read-only-space*

o Update to use new allocation macro for gencgc.

o Add necessary static symbols to support gencgc.

o Update to build with gencgc as needed.

o Update C code for gencgc.  Mostly for checking if pointer is in the
  dynamic space.
o Many debugging printf's enabled.

o Adjust sparc version appropriately for ppc.
o Enable many gencgc self-checks.

o Update PAGE_SIZE for ppc, which is 4K.

o Add necessary code to handle the allocation traps for gencgc.
  Basically ported sparc version for ppc.

o The way pseudo-atomic is done has been changed, so make the assembly
  code match.  PA is now more like sparc where the LSB is the
  PA-interrupted bit.
o do_pending_interrupt may need work.

o Make the READ_ONLY_SPACE_SIZE right.

o Enable debugging printfs
o Adjust purify for gencgc, basically copying sparc version.

o Lots of printf's so we can see what's happening on ppc since gdb is
  majorly broken there.

o Actually implement the function-end breakpoint template.  Basically
  copied the sparc version, with appropriate mods.

o Add TWLLEI_R0 macro to create the appropriate trap instructions that
  we need, and use as appropriate.
o arch_install_breakpoint was actually broken and installed a twllgei
  instruction instead of twllei.
o arch_do_displaced_inst was also broken.  It didn't install the
  after-break-point trap after the breakpoint trap.  And it also
  didn't continue running the code and returned instead.  That's
o The trap_AfterBreakpoint case in sigill_handler was inserting the
  wrong instruction back.  (Probably too much copying of the sparc

Initial support for linkage-tables on PPC/Darwin.  This is a
relatively straightforward port of the sparc version of
linkage-tables.  Some refinements are probably still needed, as well
as some testing.

Use boot-2005-02-ppc-linkage.lisp to bootstrap this change from the
2005-02 snapshot.

* code/ppc-vm.lisp
    functions for linkage-table.

* compiler/generic/new-genesis.lisp
  o Basically do the same as the sparc port for linkage-tables.
  o need to extern-alien-name on the cold linkages since they C names
    depend on the backend conventions.

  o Load "undefined_tramp" appropriately for linkage-tables.

* compiler/ppc/c-call.lisp
    FOREIGN-SYMBOL-DATA-ADDRESS) for linkage-tables so we can access

* compiler/ppc/cell.lisp
  o Load "closure_tramp" appropriately for linkage-tables
  o Load "undefined_tramp" appropriately for linkage-tables

* compiler/ppc/parms.lisp
  o Put the foreign linkage space start at the end of the static space
    to make it easier to bootstrap.  (We need already mapped memory.)
    We can move this later.
  o Add new static-symbol *linkage-table-data*
  o While were at it, add SPARE-9 and SPARE-0 static symbols so we
    have 10 spares.

* lisp/Config.ppc_darwin
  o Add -DLINKAGE_TABLE to CFLAGS/ASFLAGS if we have linkage-table

* lisp/Darwin-os.c
  o Add os_dlsym to support linkage-tables.  (This nees a little
    refactoring because we just copied the #defines for dlopen modes.)

* lisp/os-common.c
  o The checking of the linkage tables that is done for sparc almost
    works for ppc, but not quite.  Implement one for ppc.

* lisp/ppc-arch.c
  o Add PPC version of arch_make_jump_entry, arch_make_linkage_entry,

* lisp/ppc-assem.S
  o Add lazy_resolve_linkage to support linkage-tables.  This needs
    some more work.
  o Add undefined_foreign_symbol_trap.  This probably needs work, and
    definitely needs testing.

* lisp/ppc-validate.h
  o Define the start of the linkage space and size.

(defun foo () (zot)) when compiled and run gave a silly message about
#C(0d0 0d0) failing a typecase.  Then doing a backtrace gave another
error about some negative number not being a positive fixnum.

The former error is caused by a bad definition of undefined_tramp.
The latter error is caused by the debugger not being able to compute
the offset correctly.

First merge of the C side of the OS X/Darwin port.  Besides adding Darwin
versions of all the required things, this commit separates the
interrupt handler proper (now interrupt_handle_now_handler) from the
actual work-horse (interrupt_handle_now), which is now only ever called
from the two interrupt handlers, interrupt_handle_now_handler and
maybe_now_maybe_later.  This follows similar changes in SBCL, and is in
fact needed in order to properly use sigreturn in signal handlers, as
required to work around a problem with the G5.
