19    Description:
20    
21    Removed the "Release_110_37" tag because of a serious bug.
22    This will be re-tagged once the bug is fixed.

30    Forgot to add a file.  (Just a .tex-file -- part of
31    the CM manual source.)

37    Description:
38    
39    Note: I removed the original tag "Release_110_37" from this commit
40          because we found a serious bug in all non-x86 backends.
41          - Matthias
42    
43    1. Modifications to the SML/NJ code generator and to the runtime system
44       so that code object name strings are directly inserted into code
45       objects at code generation time.  The only business the runtime system
46       has with this is now to read the name strings on occasions.
47       (The encoding of the name string has also changed somewhat.)
48    
49    2. CM now implements a simple "set calculus" for specifying export lists.
50       In particular, it is now possible to refer to the export lists of
51       other libraries/groups/sources and form unions as well as differences.
52       See the latest CM manual for details.
53    
54    3. An separate notion of "proxy" libraries has again be eliminated from
55       CM's model.  (Proxy libraries are now simply a special case of using
56       the export list calculus.)
57    
58    4. Some of the existing libraries now take advantage of the new set
59       calculus.
60       (Notice that not all libraries have been converted because some
61       of the existing .cm-files are supposed to be backward compatible
62       with 110.0.x.)
63    
64    5. Some cleanup in stand-alone programs.  (Don't use "exnMessage" -- use
65       "General.exnMessage"!  The former relies on a certain hook to be
66       initialized, and that often does not happen in the stand-alone case.)

72    Description:
73    
74      Implemented a complete redesign of MLRISC pseudo-ops. Now there
75      ought to never be any question of incompatabilities with
76      pseudo-op syntax expected by host assemblers.
77    
78      For now, only modules supporting GAS syntax are implemented
79      but more should follow, such as MASM, and vendor assembler
80      syntax, e.g. IBM as, Sun as, etc.

86    Description:
87    
88    1. Routed the name of the current source file to mlriscgen where it
89       should be directly emitted into the code object.  (This last part
90       is yet to be done.)
91    
92    2. Some cleanup of the pgraph code to make it match the proposal that
93       I put out the other day.  (The proposal notwithstanding, things are
94       still in flux here.)

101    
102      Fix for a backpatching bug reported by Allen.
103    
104      Because the boundary between short and long span-dependent
105      instructions is +/- 128, there are an astounding number of
106      span-dependent instructions whose size is over estimated.
107    
108      Allen came up with the idea of letting the size of span
109      dependent instructions be non-monotonic, for a maxIter
110      number of times, after which the size must be monotonically
111      increasing.
112    
113      This table shows the number of span-dependent instructions
114      whose size was over-estimated as a function of maxIter, for the
115      file Parse/parse/ml.grm.sml:
116    
117         maxIter            # of instructions:
118            10                      687
119            20                      438
120            30                      198
121            40                        0
122    
123      In compiling the compiler, there is no significant difference in
124      compilation speed between maxIter=10 and maxIter=40. Actually,
125      my measurements showed that maxIter=40 was a tad faster than
126      maxIter=10! Also 96% of the  files in the compiler reach a fix
127      point within 13 iterations, so fixing maxIter at 40, while high,
128      is okay.

133    Tag: blume-20011031-pgraph
134    Description:
135    
136    CKIT:
137    * Changed the "Function" constructor of type Ast.ctype to carry optional
138      argument identifiers.
139    * Changed the return type of TypeUtil.getFunction accordingly.
140    * Type equality ignores the argument names.
141    * TypeUtil.composite tries to preserve argument names but gives up quickly
142      if there is a mismatch.
143    
144    installation script:
145    * attempts to use "curl" if available (unless "wget" is available as well)
146    
147    CM:
148    * has an experimental implementation of "portable graphs" which I will
149      soon propose as an implementation-independent library format
150    * there are also new libraries $/pgraph.cm and $/pgraph-util.cm
151    
152    NLFFI-LIB:
153    * some cleanup (all cosmetic)
154    
155    NLFFIGEN:
156    * temporarily disabled the mechanism that suppresses ML output for
157      C definitions whose identifiers start with an underscore character
158    * generate val bindings for enum constants
159    * user can request that only one style (light or heavy) is being used;
160      default is to use both (command-line arguments: -heavy and -light)
161    * fixed bug in handling of function types involving incomplete pointers
162    * generate ML entry points that take record arguments (i.e., using
163      named arguments) for C functions that have a prototype with named
164      arguments
165      (see changes to CKIT)

171    Description:
172    
173       Fixed the bug described in blume-20010920-slowfp.
174    
175       The fix involves
176          1. generating FCOPYs in FSTP in ia32-svid
177          2. marking a CALL with the appropriate annotation
