20    More cleanup after changing the file naming scheme: This time I
21    repaired the parallel make mechanism for CMB.make which I broke earlier.

28    None of these things should affect normal SML/NJ operations
29    
30    1. Peephole improvements provided by Fermin (c--)
31    2. New annotation DEFUSE for adding extra dependence (moby)
32    3. New X86 LOCK instructions (moby)
33    4. New machine description language for reservation tables (scheduling)
34    5. Fixes to various optimization/analysis modules (branch chaining, dominator
35       trees etc.)
36    6. I've changed the CM files so that they can work with versions
37       110.0.6, 110.25 and 110.28

43    Description:
44    
45    - Removed all(?) remaining RCS Log entries from sources.
46    
47    - Fixed bug in ml-yacc and ml-lex sources (use explicit anchors for
48      anchored paths).

53    Tag: blume-20000607-no-implicit-anchors
54    Description:
55    
56    1. This update changes the default setting for
57    CM.Control.implicit_anchors from true to false.  This means that
58    implicit anchors are no longer permitted by default.  I also tried to
59    make sure that nothing else still relies on implicit anchors.
60    (This is the next step on the schedule towards a CM that does not even
61    have the notion of implicit anchors anymore.)
62    
63    2. More CM manual updates.
64    
65    3. I managed to track down and fix the pickling bug I mentioned last
66    time.  Because of the previously existing workaround, this entails no
67    immediate practical changes.

73    Description:
74    
75    !!!! NEW BOOT FILES !!!!
76    
77    * The main purpose of this update is to make library pickles lazier in
78    order to reduce the initial space penalty for autoloading a library.
79    As a result, it is now possible to have $smlnj/compiler.cm
80    pre-registered.  This should take care of the many complaints or
81    inquiries about missing structure Compiler.  This required changes to
82    CM's internal data structures and small tweaks to some algorithms.
83    
84    As a neat additional effect, it is no longer necessary (for the sake
85    of lean heap image files) to distinguish between a "minimal" CM and a
86    "full" CM.  Now, there is only one CM (i.e., the "full" version:
87    $smlnj/cm.cm aka $smlnj/cm/full.cm), and it is always available at the
88    interactive top level. ($smlnj/cm/minimal.cm is gone.)
89    
90    To make the life of compiler-hackers easier, "makeml" now also
91    pre-registers $smlnj/cmb.cm (aka $smlnj/cmb/current.cm).  In other
92    words, after you bootstrap a new sml for the first time, you will not
93    have to autoload $smlnj/cmb.cm again afterwards.  (The first time
94    around you will still have to do it, though.)
95    
96    * A second change consists of major updates to the CM manual.  There
97    are now several appendices with summary information and also a full
98    specification of the CM description file syntax.
99    
100    * In directory src/system I added the script "allcross".  This script
101    invokes sml and cross-compiles the compiler for all supported
102    architectures.  (Useful when providing a new set of boot files.)
103    
104    * There seems to be a latent bug in my "lazy pickles" mechanism.  I
105    added a small tweak to pickle-util.sml to work around this problem,
106    but it is not a proper fix yet.  I will investigate further.  (The
107    effect of the bug was an inflation of library pickle size.)
108    
109    * Version number increased to 110.28.1 (to avoid compatibility problems).
