Create a branch for the transition to the new runtime system.

merge revisions 2221:2491 from primop-branch-3

eliminated src dir

merged changes from mcz-branch (tag: dbm-20030813-mcz-merge1)

updates to pgraph and, more importantly, to NLFFI

Release 110.37 -- see HISTORY

srcname routed to mlriscgen;
more fiddling with pgraph (portable library graph) code

updates to CKIT, CM, NLFFI, and scripts (see HISTORY)

updates to environments, envrefs, interactive loop

extensive organizational changes

index-file generation in CM; small changes to c-calls API

parallel make works again

merging changes from private branch

merging changes from private branch

further improvements to link traversals and (as a result) autoloading;
See HISTORY for how to bootstrap!

merged the big housecleaning patch (see HISTORY!)

added conditional compilation in init library; BOOTFILES

merging back my devel changes (anchor environments)

merging changes from devel branch; new boot files

bring revisions from the vendor branch to the trunk

CM.sources implemented; CM.makedepend dropped

merged pending changes into main trunk; see HISTORY; new binfiles!!

merging back development branch blume_devel_v110p26p1_3...
This involves changes to CM and the removal of CMStaticEnv from
the compiler.  See the HISTORY file for more information.

merging back changes from blume_devel_v110_26_2

- size info in BOOTLIST
     * no fixed upper limits for number of bootfiles or length of
       bootfile names in runtime
     * falling back to old behavior if no BOOTLIST size info found
- allocation size heuristics in .run-sml
     * tries to read cache size from /proc/cpuinfo (this is important for
        small-cache Celeron systems!)
- install.sh robustified
- CM manual updates
- paranoid mode
     * no more CMB.deliver() (i.e., all done by CMB.make())
     * can re-use existing sml.boot.* files
     * init.cmi now treated as library
     * library stamps for consistency checks
- sml.boot.<arch>-<os>/PIDMAP file
     * This file is read by the CM startup code.  This is used to minimize
       the amount of dynamic state that needs to be stowed away for the
       purpose of sharing between interactive system and user code.
- CM.Anchor.anchor instead of CM.Anchor.{set,cancel}
     * Upon request by Elsa.  Anchors now controlled by get-set-pair
       like most other CM state variables.
- Compiler.CMSA eliminated
     * No longer supported by CM anyway.
- fixed bugs in pickler that kept biting Stefan
     * past refs to past refs (was caused by the possibility that
       ad-hoc sharing is more discriminating than hash-cons sharing)
     * integer overflow on LargeInt.minInt
- ml-{lex,yacc} build scripts now use new mechanism
  for building standalone programs
- fixed several gcc -Wall warnings that were caused by missing header
  files, missing initializations, etc., in runtime (not all warnings
  eliminated, though)

CM changes: standalone builds, better CMB.make/deliver, general improvements

pickle dropper

relative osstrings; groupsOf

even ordering in master-slave protocol improved

in-degree calculation and prioritizing added

CMB.deliver (and probably CM.stabilize) now work with compile servers

getting ready for parallel...

annoying path confusion bug fixed

some small bugs squashed

new stable format + improved recompile/link (in progress, not working yet)

Elsa's bug fixed

just syncing; this version does not work

aliases eliminated

backed out of thin traversals

thin traversals implemented (whew!)

more inching towards a usable system

bootstrapping now working (it seems)

listfile generation fixed

more work towards being able to bootstrap

autoloading added

a host of changes related mostly to pathname handling

various changes in pathname handling etc.

wrapped privileges cleaned up; Overview updated

groups not stabilizable by themselves (sucked into surrounding stable library)

stablefile format enhanced; bootstrap compiler shows signs of life

bootstrap compiler half-working

value cache implemented correctly

stabilization code working but only flimsily hooked up

stabilization code completed -- still needs to be hooked up

simplified da-env

more stabilization code (still not done, though)

stabilization code mostly done

some more fiddling with the stablefile pickler

first steps towards stabilize (not finished yet)

dyn-tstamp eliminated; more fiddling with sharing (now checked statically)

recompile and exec mostly working (probably still bugs in the details)

finished recomp.sml; now only need to put the pieces together

persistent state/error handling bogosity fixed

most of recompilation/execution machinery in place

first steps towards make/recompile and stable libraries

skeleton code rewritten (should contain no more code inherited from SC)

new attempt at Skeletons (not quite satisfactory yet)

skeleton type simplified; improved conversion, etc.

full dependency analysis (hopefully) in place

stdtool as function; better depend. graphs, group export grammar fixed

GroupReg added; bad error msg behavior fixed

some cosmetic changes to error reporting

dependency analysis (hopefully) done; some simplifying changes to skeletons

more towards dependency analysis

early beginning of dep. analysis

checking for group cycles implemented (with nicely formatted error message)

implementation of Tools mechanism added

semant/members.sml should be fairly complete now

started adding dependency graph stuff
