* 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.

sources.  No real attempt has been made to make it work, but the
cross-compile does create a kernel.core, and the C code compiles (on
openSuSE 10.3).  The resulting kernel.core does not yet work.

Use cross-x86-amd64.lisp as the cross-compile script.  This is
intended to be cross-compiled using the 20a release for Linux, and
only supports x87.  The sse2 support has not be ported yet.

tools/cross-scripts/cross-x86-amd64.lisp:
o Update cross-compile with some missing constants, and frob new
  symbols.

tools/clean-target.sh:
o Remove amd64f files too.

code/pred.lisp:
o Define predicates for double-doubles for bootstrapping to work
  around recursive known function problems with these predicates.

code/sap.lisp:
o Define int-sap with (unsigned-byte 64) type declaration.  (May not
  be needed?)

code/unix-glibc2.lisp:
o Build fails defining map_failed to (int-sap -1).  Just hard-wire to
  0 for now so we can build.

compiler/float-tran.lisp:
o Add missing conditional for %complex-double-double-float.

compiler/amd64/float.lisp:
o Merge double-double support for amd64.  Not really tested yet.

compiler/amd64/parms.lisp:
o Update to match x86 build.  In particular, get the space address
  correct and update the static symbols.

compiler/amd64/type-vops.lisp:
o DYLAN-FUNCTION-HEADER-TYPE no longer exists.

compiler/amd64/vm.lisp:
o Add double-double storage classes and register definitions.

lisp/Config.amd64:
o Bring in line with Config.x86 and friends.

lisp/Linux-os.c:
o Bring amd64 code up-to-date with x86/linux code.

lisp/Linux-os.h
o Need to include sys/ucontext.h to get ucontext defined.  (Why?)
o Also define __USE_GNU so we get the register offsets in the ucontext
  defined.  (Why?)

lisp/amd64-arch.c:
o Change struct sigcontext to os_context_t.
o Use SC_PC instead of context->sc_pc.
o Merge some changes in from x86 version, like SC_EFLAGS.  May need
  more work.

lisp/amd64-assem.s:
o Use rbx instead of ebx for jmp.

lisp/amd64-lispregs.h:
o Define SC_REG, SC_PC, SC_SP using the new x86 style.

lisp/backtrace.c:
o Remove inline assembly for now until I figure out what the amd64
  version should be.

lisp/gencgc.c:
o Conditionalize out weak hash table support for now.

lisp/gencgc.h:
o Set PAGE_SIZE for amd64.  (Is 4096 right?)

lisp/globals.h:
o Export current_dynamic_space_free_pointer and
  current_auto_gc_trigger like for x86.

Use bootstrap-2009-01-1.lisp to bootstrap this change.

code/float-trap.lisp:
o FLOATING-POINT-MODES for :X87 needs to massage the results into the
  expected format (SSE2 MXCSR order).
o Update for changed VOP names too.

compiler/x86/float.lisp:
o Rename the floating-point-modes and set-floating-point-modes VOPS to
  x87-floating-point-modes and set-x87-floating-point-modes.  Change
  the translations accordingly too.

compiler/x86/parms.lisp:
o The float property bytes have been updated to match the SSE2 MXCSR
  register for both SSE2 and X87 builds because the code assumes SSE2
  format.

lisp/Linux-os.c:
o Don't OR in the SSE2 modes if we're not running an SSE2 build.
  Doing this can erroneously mask out exceptions because the Lisp code
  didn't set up the sse2 modes.  (This happens if you select the x87
  core on a chip that supports sse2.)

lisp/globals.h:
o Declare fpu_mode.

lisp/lisp.c:
o Set fpu_mode to be the mode determined from the core file.  Needed
  in Linux-os.c to process the SSE2 modes correctly with an x87 core
  on a sse2-capable chip.

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

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.

  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.

*internal-gc-trigger* for the RT, and allocators explicitly test against
it.

to the sigtrap handler so that lisp can still get at the other fpe's.
Added all the necessary magic to get auto-gcing to work.

frames and preserve the frame pointer.  Backtrace now gives a complete
backtrace, not just from the last sigcontext.
