   was the RCS header.

dirname being undefined.

lisp/elf.c:
lisp/mach-o.c:
o Remove obj_cleanup function.

lisp/save.c:
o Don't call obj_cleanup anymore (because it doesn't exist.)

toosl/linker-x86.sh:
o Remove CORRO.o CORSTA.o CORDYN.o on exit.

images.

lisp/elf.c:
o Change write_elf_object, elf_cleanup, and elf_run_linker to
  write_space_object, obj_cleanup, and obj_run_linker.

lisp/elf.h:
o Update so that this can used for both elf and mach-o.  Not great,
  but I don't want to rename this file.

lisp/mach-o.c:
o Include elf.h
o Remove items that are defined in elf.h.
o Change function names from elf to mach_o.

lisp/save.c:
o Update names to new ones.

executable appears to work!

bootfiles/20a/boot-2010-07-1.lisp:
o Add :executable for darwin/x86.

code/bsd-os.lisp:
o Make :elf and :mach-o runtime features too.
o Register :executable of :executable is defined.

lisp/Config.x86_darwin:
o Need mach-o.c
o Add exec-final.c

lisp/lisp.c:
o Don't include elf.h if we're on Darwin since Darwin uses Mach-O, not
  ELF.
o For Darwin, we get the initial function address from
  initial_function_addr, not from &initial_function_addr, like for
  Linux.

lisp/save.c
o Don't include libgen.h and elf.h on Darwin.

tools/linker-x86.sh:
o Update to support Darwin.

tools/make-main-dist.sh:
o Add support for executables on Darwin.

lisp/mach-o.c:
o Initial support for writing Mach-O files for the Lisp spaces.
o Initial support for reading a Mach-O executable to find and map the
  Lisp spaces.

initial_function_addr is saved to a file and compiled in when linking
the executable.  This makes building the executable more portable.
All that's need is a way for gcc to link all of lisp.a and to set the
starting address of some segments.

lisp/lisp.c:
o For Linux, use the value of initial_function_addr instead of the
  address.

tools/linker-x86.sh:
o Disable -x option, unless CMU_DEBUG_LINKER is not empty.
o Instead of using --defsym feature of GNU ld, save the initial
  function address in a file to be compiled when making the
  executable.

lisp/elf.c:
o Remove printing of the sizeof elf headers
o Print some info about the object being written and print somewhat
  neatly.

lisp/save.c:
o Rework printing info of the core objects.  Let write_elf_object do
  it.

hairy and fragile linker script.  Instead, we can use regular old gcc
to do what we need.

(Should also work for FreeBSD, but not yet implemented.)

lisp/elf.c:
o Include validate.h so we can get the starting addresses of the
  read-only, static, and dynamic spaces.
o Add special case for linux to run the linker script correctly.

lisp/elf.h:
o There's a separate linker script for Linux.

lisp/save.c:
o Temporarily don't run elf_cleanup so we can have easier
  testing/debugging.

tools/linker.sh:
o Don't need BIFLAG anymore.

tools/make-main-dist.sh:
o Install linker-x86.sh.

destructively modifies its argument.

lisp/save.c:
o Call dirname once, saving the result, and use it everywhere.

compile-time options to do this.  The running core file has to tell
us.

lisp/save.c:
o Add extra arg to save function to indicate whether the core we're
  saving supports sse2 or not.  Non-zero means sse2.
o Put the correct indication into the core file.

lisp/save.h:
o Update declaration of save.

code/save.lisp:
o Update alien definition for save
o Pass in the extra parameter for the save routine to indicate if we
  support sse2 or not.

issue and also works around the heap corruption.  These are enabled if
DEBUG_BAD_HEAP is #defined.

gencgc.c:
o Make print_ptr and verify_gc non-static so they can be used
  elsewhere.

lisp.c:
o Call verify_gc at startup (if enabled) so we can see the heap
  corruption.

save.c:
o Add debugging prints and stuff to see what's going on, if enabled.
o The workaround is to skip over the call to
  update_dynamic_space_free_pointer in save().  See the comments there
  for more info.

* os-common.c: Include interrupt.h to define

* parse.c, runprog.c, search.c:  Include some standard system headers

kind of setup it wants.  This makes a saved lisp totally independent of the
location of the C stack.
