* Get rid of the RCS Header stuff.  They're meaningless in git.
 * Add public domain comment to some of the files if the only comment
   was the RCS header.

sunos-os.h:
o Update HANDLER_ARGS to match definition used in sigaction.
o Define os_context_t

lisp.c:
solaris-os.c:
sparc-arch.c:
o Use os_context_t as needed.

Make the size of all spaces configurable from the command line.

code/commandline.lisp:
o Define the switches so lisp doesn't complain.

general-info/lisp.1:
o Document new switches.

general-info/release-20c.txt:
o Update

lisp/Darwin-os.c
lisp/FreeBSD-os.c
lisp/Linux-os.c
lisp/NetBSD-os.c
lisp/backtrace.c
lisp/cgc.c
lisp/gencgc.c

lisp/ppc-validate.h
lisp/purify.c
lisp/solaris-os.c
lisp/sparc-arch.c
lisp/sparc-validate.h
lisp/x86-validate.h:
lisp/validate.c
o Basically rename CONTROL_STACK_SIZE, BINDING_STACK_SIZE,
  READ_ONLY_SPACE_SIZE, and STATIC_SPACE_SIZE to control_stack_size,
  binding_stack_size, read_only_space_size, and static_space_size,
  respectively.

lisp/coreparse.c
o Check the space size in the core file against the allocated size.
  If the allocated space is too small, print an error message and
  exit.

lisp/globals.c
o Define new variables for the allocated size of spaces.

lisp/globals.h
o Declare the new variables for the size of the spaces.

lisp/lisp.c
o Set the default values of the spaces.
o Parse the new command-line flags and set the space sizes.

lisp/sunos-os.c:
o Added os_init0 (that we forgot last time).

lisp/x86-assem.S:
o Change $CONTROL_STACK_END to GNAME(control_stack_end) to get the
  correct end of the stack.

sse2-packed-2008-11-12).

void keyword to specify empty parameter lists.

.indent.pro.

with gencgc because the interrupt handler eventually calls Lisp code
that might cons.

because it calls handle_breakpoint which eventually calls into Lisp.
Gencgc allocation needs SIGILL enabled.

and resolve_linkage_tramp in sparc-assem.S.

the handler, which seems to be a bad idea since interrupt_handle_now
has comments about alloc_sap while interrupts are disabled.

Not 100% sure this is all right, but everything still appears to work.

* gencgc.h:  Add declaration for alloc.

* solaris-os.c:
  o Include interrupt.h
  o Clean up some printf warnings, apply appropriate casts for
    converting address to longs and vice versa.

* sparc-arch.c:
  o Include gencgc.h, breakpoint.h, interr.h to declare some functions
    for us.
  o Instructions are ints, not longs.  (64-bitness cleanup.)
  o handle_breakpoint and handle_function_end_breakpoint were not
    called with the right second arg.

* sunos-os.h:
  o Declare flush_icache and save_context.

CMUCL doesn't use the taddcctv/tsubcctv instructions anymore.

current-region-free-pointer.

Cross compile may be needed, but I'm not sure.  I only used
cross-compiling to do this change.

sparc/macros.lisp:
o Update the allocation macro appropriately for alloc-tn holding the
  current-region-free-pointer.

lisp/gencgc.c:
o Define macros for setting and getting *current-region-free-oointer*
  and *current-region-end-addr* so sparc can use alloc-tn.
  *current-region-free-pointer* isn't used anymore, but is still a
  static symbol.  It's been replaced by alloc-tn.
o On sparc, set_alloc_pointer doesn't need to do anything anymore.
o Don't need to call update_dynamic_space_free_pointer anymore.
o The assertion that *current-region-free-pointer* is a fixnum is no
  longer valid on sparc because that is alloc-tn which contains the
  pseudo-atomic bits.

lisp/sparc-arch.c:
o The allocation trap instruction is now preceeded by a SUB
  instruction.  Handle that correctly.  Keep support for the OR
  instruction for now, but should be removed.
o Set alloc-tn from current_dynamic_space_free_pointer.

overflow checking.  Enable with :heap-overflow-check.  We reserve some
number of pages on the heap.  When the heap reaches the reserved
pages, an overflow warning is signalled.  The reserved pages are set
0.  This allows some additional allocation to happen during debugging,
if necessary.  If another overflow happens, we throw to top-level.

Sparc only right now.

	* lisp/sparc-assem.S (_do_dynamic_space_overflow_error): New
	function to handle a heap overflow error.
	(_do_dynamic_space_overflow_warning): New function to handle heap
	overflow warning.

	* lisp/sparc-arch.c (sigill_handler): Handle the two new traps
	caused by heap overflows.

	* lisp/interrupt.c (interrupt_handle_space_overflow): New function
	to handle interrupt caused by heap space overflows.

	* lisp/gencgc.c (handle_heap_overflow): New function to handle
	heap overflows.
	(gc_alloc_new_region): Use handle_heap_overflow.
	(gc_alloc_large): Use handle_heap_overflow

	* compiler/sparc/parms.lisp (static-symbols): Add new static
	symbols for heap overflow checking:
	dynamic-space-overflow-error-hit and
	dynamic-space-overflow-warning-hit.

	* compiler/generic/new-genesis.lisp (finish-symbols): Initialize
	the new dynamic-space-overflow-error-hit and
	dynamic-space-overflow-warning-hit static symbols.

	* code/lispinit.lisp (:heap-overflow-check): Add
	heap-overflow-check to *runtime-features*, if necessary.
	("reserved_heap_pages"): Access to alien variable for heap
	overflow.
	(*reserved-heap-pages*): Default number of heap pages to reserve
	for heap overflow.
	(%top-level): Set reserved-heap-pages to the default.

	* code/interr.lisp (dynamic-space-overflow-warning-hit): Add
	function to handle heap overflow warnings.
	(dynamic-space-overflow-error-hit): Add function to handle heap
	overflow error.

	* code/error.lisp (heap-overflow): Add new condition type for heap
	overflow

sigill_handler was enabling them, and this messes up allocation if a
signal should happen during allocation.  (Thanks to Dan Barlow for
help hints.)

pseudo_atomic_InterruptedValue instead of the bare 7's, 4's, and 3's
and 1's in the code.

o Export ALLOCATION-TRAP so genesis will put a #define for
  trap_Allocation in internals.h

lisp/sparc-arch.c:
o Use trap_Allocation instead of a hard-wired 31.

o Make new-genesis save target-foreign-linkage-table-size to
  internals.h.

be more careful about identifying exactly the form used for the
pseudo-atomic trap.

o Clean up the code a little, and delete the unused stuff about Sparc
  V9 not liking the trap instructions (that we don't generate
  anymore).

o Add routines to handle the new pseudo-atomic trap noise instead of using
  taddcctv.  The old code is left in just in case I forgot some uses somehow.
o Don't try to fix up broken trap instructions anymore.  We shouldn't be
  generating them at all now anyway.

  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.
