19    Description:
20    
21    Assorted cleanup work:
22    
23      - got rid of intstrmap in favor of using the library's
24        hash table implementation
25      - threw out most of the pathnames stuff, as it was not used anyway
26      - simplified tokentable implementation
27      - fixed some minor spelling errors

33    Description:
34    
35    Cleaned up the absyn to reflect the invariant that HANDLE always
36    carries a FNexp as part of the type definition.  This eliminates some
37    superfluous sanity checks at runtime down the road.
38    
39    Some minor cleanup of the btrace code.

45    Description:
46    
47    Added hack to make slave mode work in the presence of the version
48    tool.  (Still, since the master does two passes over the code for
49    CMB.make, the release number gets bumped twice when slaves are
50    attached.  I don't know if this is worth fixing...)

56    Description:
57    
58    * Moved the "version" magic into its own little library under
59    src/system/smlnj/internal.  This avoids expensive reconstruction
60    of a stable src/compiler/core.cm.
61    
62    * At the same time, structure CompilerVersion is now known as structure
63    SMLNJVersion.
64    
65    * Arranged for the version tool to NOT kick in when rebuilding the system
66      (makeml -rebuild, fixpt).  Otherwise one would never reach a fixpoint.
67      Also, loading the versiontool does not work when rebuilding the system
68      because CM is not properly initialized at that time.

73    Tag: blume-20040929-autoversion
74    Description:
75    
76    Implemented some CM magic to have
77        file src/compiler/TopLevel/main/version.sml
78    generated automagically.
79    The version is taken from two files: config/version and config/release.
80    The first is expected to contain a two-part version number such as 110.49.
81    The second should contain a single number, but it may be missing.
82    
83    If the environment variable VERSIONTOOL_BUMP_RELEASE is defined at the
84    time the version tool is loaded (which is the first time you say CMB.make),
85    then the tool will increment the value stored in config/release every
86    time CMB.make is invoked.
87    
88    The binfile format is now insensitive to anything beyond the first
89    two components of a version number, so bumping the release does not render
90    binfiles incompatible.  Auto-bumping can be used to keep track of versions
91    during development without invalidating existing binfiles.
92    
93    In any case, every CMB.make updates the date information in version.sml.
94    (This is the date that is printed in the banner.)

107    Tag: blume-20040927-controls
108    Description:
109    
110    Added two pieces of functionality to the Controls interface:
111    
112    1.   val save'restore: 'a control -> unit -> unit
113    
114       grabs the current value of the control in stage 1 and restores it
115       in stage 2.
116    
117    2.   val set' : 'a control * 'a -> unit -> unit
118    
119       stores the given value into the control in stage 2 (i.e., delayed)
120       but does all error checking in stage 1.
121       (This is for string controls that need to do parse their argument --
122        something that might fail.  In some cases, notably in CM, one
123        already knows the intended argument but wants to delay the actual
124        assignment until a time when error recovery would be more difficult.)
125    
126    Changed the handling of controls in tool arguments to classes "sml" and
127    "lazysml":
128       - use Controls.save'restore as a more robust way of restoring the
129         old value (in particular: without having to re-parse the string)
130       - use controls to handle the "overload" keyword in the init group
131         (I believe this change actually fixes a long-standing obscure bug.)

136    Tag: blume-20040927-lazysml
137    Description:
138    
139    Added a new tool class called "lazysml" to CM's tool chest.  The only
140    difference to "sml" is that compilation is done with Control.lazysml
141    set to true.  A source of class "lazysml" is automatically recognized
142    by a file name suffix of ".lml".
143    
144    In addition to the above feature, the original class "sml" now also
145    supports a tool argument "lazy" which has the same effect.  As a
146    result, the following three lines are equivalent:
147    
148        foo.sml : lazysml
149        foo.sml : sml (lazy)
150        foo.sml (lazy)
151    
152    The setting goes into effect both during parsing and during
153    compilation.  The original setting is restored right after parsing and
154    after compilation, respectively.
155    
156    In addition to all the above, there is also a general mechanism to set
157    ANY of the "controls" that are available at the command line via
158    "-C..." on a per-sml-file basis.  The same rules that apply for "lazy"
159    apply as well. (In fact, "lazy" is implemented as a special case of
160    the general mechanism.)
161    
162    The .cm file syntax uses a new keyword tool argument called "with".
163    There are several ways of indicating the desired settings:
164    
165        foo.sml (with:parser.quotations=true)
166        foo.sml (with:(name:parser.quotations value:true))
167        foo.sml (with:(name:name1 value:value1 name:name2 value:value2 ...))
168        foo.sml (with:(name1=value1 name2=value2 ...))
169        foo.sml (with:(name1=value1 name:name2 value:value2 name3=value3 ...))
170    
171        etc.
172    
173    Another possible abbreviation is to leave out the =v or value:v part
174    if the name refers to a boolean control (in which case the value is
175    taken to be true).  Thus, one could get lazy sml also by saying:
176    
177        foo.sml (with:parser.lazy-keyword=true)
178        foo.sml (with:parser.lazy-keyword)
179        foo.sml (with:(name:parser.lazy-keyword value:true))
180        foo.sml (with:(name:parser.lazy-keyword))

186    Description:
187    
188    Turned message about "emiting long form of branch" off by default.
189    Added a control flag to turn it back on when desired.

198    Melissa O'Neill for providing the code!
