* 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.

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/os-common.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.

having to be in low memory.  This is done be replacing the absolute
branch instructions with equivalents that can branch anywhere.  This
adds a few extra instructions everywhere.  Oh well.

We also move the READ-ONLY space to a different location so we don't
need the linker hacks and the darwinadjuster hacks.

A basic cross-compile is necessary.  Use boot-2006-11-1-cross-ppc.lisp
for this.

assembly/ppc/assem-rtns.lisp:
compiler/ppc/call.lisp:
o Replace BA instruction with BCTR.

assembly/ppc/support.lisp:
o Replace BLA instruction with BCTRL.
o Replace BA instruction with BCTR.

compiler/ppc/parms.lisp:
lisp/ppc-validate.h:
o Move the read-only space to #x04000000 instead of #x01000000.  (This
  address appears to be free.)

lisp/Config.ppc_darwin:
o Comment out the linker flags for the CMUCLRO space.
o Don't run the darwin-lispadjuster program.  (We still build
  darwin-lispadjuster for now, but that should be removed eventually.)

.indent.pro.

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
  o Add appropriate FOREIGN-SYMBOL-ADDRESS-AUX and FIND-FOREIGN-SYMBOL
    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.

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

* compiler/ppc/c-call.lisp
  o Define new vops (FOREIGN-SYMBOL-CODE-ADDRESS,
    FOREIGN-SYMBOL-DATA-ADDRESS) for linkage-tables so we can access
    correctly.

* 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 Correct TARGET-FOREIGN-LINKAGE-ENTRY-SIZE.
  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
    support.

* 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,
    arch_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.

lisp.c into the correct <foo>-os.h files.

10.3 was putting some malloc'ed areas in the old (bigger) static
space, which causes cmucl not to run.  Moving the space to 0x10000000
makes it no longer overlap.  I don't understand the reason for this.
OS X 10.2 doesn't have this problem.

Use boot-2004-10-1-ppc.lisp to cross-compile this change.

binding-stack to 128 MB each.  Increase the heap to a maximum of 512
MB, but leave the default heap at 128 MB.  The control-stack and
binding-stack were moved down just below the heap.

No bootstrap or cross-compiled required.

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.
