20    
21    Forgot to add a file.  (Just a .tex-file -- part of
22    the CM manual source.)

28    Description:
29    
30    1. Modifications to the SML/NJ code generator and to the runtime system
31       so that code object name strings are directly inserted into code
32       objects at code generation time.  The only business the runtime system
33       has with this is now to read the name strings on occasions.
34       (The encoding of the name string has also changed somewhat.)
35    
36    2. CM now implements a simple "set calculus" for specifying export lists.
37       In particular, it is now possible to refer to the export lists of
38       other libraries/groups/sources and form unions as well as differences.
39       See the latest CM manual for details.
40    
41    3. An separate notion of "proxy" libraries has again be eliminated from
42       CM's model.  (Proxy libraries are now simply a special case of using
43       the export list calculus.)
44    
45    4. Some of the existing libraries now take advantage of the new set
46       calculus.
47       (Notice that not all libraries have been converted because some
48       of the existing .cm-files are supposed to be backward compatible
49       with 110.0.x.)
50    
51    5. Some cleanup in stand-alone programs.  (Don't use "exnMessage" -- use
52       "General.exnMessage"!  The former relies on a certain hook to be
53       initialized, and that often does not happen in the stand-alone case.)

59    Description:
60    
61      Implemented a complete redesign of MLRISC pseudo-ops. Now there
62      ought to never be any question of incompatabilities with
63      pseudo-op syntax expected by host assemblers.
64    
65      For now, only modules supporting GAS syntax are implemented
66      but more should follow, such as MASM, and vendor assembler
67      syntax, e.g. IBM as, Sun as, etc.

73    Description:
74    
75    1. Routed the name of the current source file to mlriscgen where it
76       should be directly emitted into the code object.  (This last part
77       is yet to be done.)
78    
79    2. Some cleanup of the pgraph code to make it match the proposal that
80       I put out the other day.  (The proposal notwithstanding, things are
81       still in flux here.)

89      Fix for a backpatching bug reported by Allen.
90    
91      Because the boundary between short and long span-dependent
92      instructions is +/- 128, there are an astounding number of
93      span-dependent instructions whose size is over estimated.
94    
95      Allen came up with the idea of letting the size of span
96      dependent instructions be non-monotonic, for a maxIter
97      number of times, after which the size must be monotonically
98      increasing.
99    
100      This table shows the number of span-dependent instructions
101      whose size was over-estimated as a function of maxIter, for the
102      file Parse/parse/ml.grm.sml:
103    
104         maxIter            # of instructions:
105            10                      687
106            20                      438
107            30                      198
108            40                        0
109    
110      In compiling the compiler, there is no significant difference in
111      compilation speed between maxIter=10 and maxIter=40. Actually,
112      my measurements showed that maxIter=40 was a tad faster than
113      maxIter=10! Also 96% of the  files in the compiler reach a fix
114      point within 13 iterations, so fixing maxIter at 40, while high,
115      is okay.

121    Description:
122    
123    CKIT:
124    * Changed the "Function" constructor of type Ast.ctype to carry optional
125      argument identifiers.
126    * Changed the return type of TypeUtil.getFunction accordingly.
127    * Type equality ignores the argument names.
128    * TypeUtil.composite tries to preserve argument names but gives up quickly
129      if there is a mismatch.
130    
131    installation script:
132    * attempts to use "curl" if available (unless "wget" is available as well)
133    
134    CM:
135    * has an experimental implementation of "portable graphs" which I will
136      soon propose as an implementation-independent library format
137    * there are also new libraries $/pgraph.cm and $/pgraph-util.cm
138    
139    NLFFI-LIB:
140    * some cleanup (all cosmetic)
141    
142    NLFFIGEN:
143    * temporarily disabled the mechanism that suppresses ML output for
144      C definitions whose identifiers start with an underscore character
145    * generate val bindings for enum constants
146    * user can request that only one style (light or heavy) is being used;
147      default is to use both (command-line arguments: -heavy and -light)
148    * fixed bug in handling of function types involving incomplete pointers
149    * generate ML entry points that take record arguments (i.e., using
150      named arguments) for C functions that have a prototype with named
151      arguments
152      (see changes to CKIT)
