19    Description:
20    
21    Fixed handling of keywords in .cm files: After seeing "is" the lexer
22    treats subsequent occurrences of "group", "library", "source", "is",
23    "*", and "-" as ordinary identifiers rather than keywords.
24    
25    Most seriously, this fixes a problem with CM's "shell" tool.  The tool
26    is supposed to accept a tool argument called "source", but this did
27    not work because of the clash with the keyword.

33    Description:
34    
35    Assorted cleanup work:
36    
37      - got rid of intstrmap in favor of using the library's
38        hash table implementation
39      - threw out most of the pathnames stuff, as it was not used anyway
40      - simplified tokentable implementation
41      - fixed some minor spelling errors

47    Description:
48    
49    Cleaned up the absyn to reflect the invariant that HANDLE always
50    carries a FNexp as part of the type definition.  This eliminates some
51    superfluous sanity checks at runtime down the road.
52    
53    Some minor cleanup of the btrace code.

59    Description:
60    
61    Added hack to make slave mode work in the presence of the version
62    tool.  (Still, since the master does two passes over the code for
63    CMB.make, the release number gets bumped twice when slaves are
64    attached.  I don't know if this is worth fixing...)

70    Description:
71    
72    * Moved the "version" magic into its own little library under
73    src/system/smlnj/internal.  This avoids expensive reconstruction
74    of a stable src/compiler/core.cm.
75    
76    * At the same time, structure CompilerVersion is now known as structure
77    SMLNJVersion.
78    
79    * Arranged for the version tool to NOT kick in when rebuilding the system
80      (makeml -rebuild, fixpt).  Otherwise one would never reach a fixpoint.
81      Also, loading the versiontool does not work when rebuilding the system
82      because CM is not properly initialized at that time.

87    Tag: blume-20040929-autoversion
88    Description:
89    
90    Implemented some CM magic to have
91        file src/compiler/TopLevel/main/version.sml
92    generated automagically.
93    The version is taken from two files: config/version and config/release.
94    The first is expected to contain a two-part version number such as 110.49.
95    The second should contain a single number, but it may be missing.
96    
97    If the environment variable VERSIONTOOL_BUMP_RELEASE is defined at the
98    time the version tool is loaded (which is the first time you say CMB.make),
99    then the tool will increment the value stored in config/release every
100    time CMB.make is invoked.
101    
102    The binfile format is now insensitive to anything beyond the first
103    two components of a version number, so bumping the release does not render
104    binfiles incompatible.  Auto-bumping can be used to keep track of versions
105    during development without invalidating existing binfiles.
106    
107    In any case, every CMB.make updates the date information in version.sml.
108    (This is the date that is printed in the banner.)

116    Some cleanup of the controls code.

121    Tag: blume-20040927-controls
122    Description:
123    
124    Added two pieces of functionality to the Controls interface:
125    
126    1.   val save'restore: 'a control -> unit -> unit
127    
128       grabs the current value of the control in stage 1 and restores it
129       in stage 2.
130    
131    2.   val set' : 'a control * 'a -> unit -> unit
132    
133       stores the given value into the control in stage 2 (i.e., delayed)
134       but does all error checking in stage 1.
135       (This is for string controls that need to do parse their argument --
136        something that might fail.  In some cases, notably in CM, one
137        already knows the intended argument but wants to delay the actual
138        assignment until a time when error recovery would be more difficult.)
139    
140    Changed the handling of controls in tool arguments to classes "sml" and
141    "lazysml":
142       - use Controls.save'restore as a more robust way of restoring the
143         old value (in particular: without having to re-parse the string)
144       - use controls to handle the "overload" keyword in the init group
145         (I believe this change actually fixes a long-standing obscure bug.)
146

150    Tag: blume-20040927-lazysml
151    Description:
152    
153    Added a new tool class called "lazysml" to CM's tool chest.  The only
154    difference to "sml" is that compilation is done with Control.lazysml
155    set to true.  A source of class "lazysml" is automatically recognized
156    by a file name suffix of ".lml".
157    
158    In addition to the above feature, the original class "sml" now also
159    supports a tool argument "lazy" which has the same effect.  As a
160    result, the following three lines are equivalent:
161    
162        foo.sml : lazysml
163        foo.sml : sml (lazy)
164        foo.sml (lazy)
165    
166    The setting goes into effect both during parsing and during
167    compilation.  The original setting is restored right after parsing and
168    after compilation, respectively.
169    
170    In addition to all the above, there is also a general mechanism to set
171    ANY of the "controls" that are available at the command line via
172    "-C..." on a per-sml-file basis.  The same rules that apply for "lazy"
173    apply as well. (In fact, "lazy" is implemented as a special case of
174    the general mechanism.)
175    
176    The .cm file syntax uses a new keyword tool argument called "with".
177    There are several ways of indicating the desired settings:
178    
179        foo.sml (with:parser.quotations=true)
180        foo.sml (with:(name:parser.quotations value:true))
181        foo.sml (with:(name:name1 value:value1 name:name2 value:value2 ...))
182        foo.sml (with:(name1=value1 name2=value2 ...))
183        foo.sml (with:(name1=value1 name:name2 value:value2 name3=value3 ...))
184    
185        etc.
186    
187    Another possible abbreviation is to leave out the =v or value:v part
188    if the name refers to a boolean control (in which case the value is
189    taken to be true).  Thus, one could get lazy sml also by saying:
190    
191        foo.sml (with:parser.lazy-keyword=true)
192        foo.sml (with:parser.lazy-keyword)
193        foo.sml (with:(name:parser.lazy-keyword value:true))
194        foo.sml (with:(name:parser.lazy-keyword))

200    Description:
201    
202    Turned message about "emiting long form of branch" off by default.
203    Added a control flag to turn it back on when desired.

210    
211    Applied patch for setting rounding modes under Mac OS X.  Thanks to
212    Melissa O'Neill for providing the code!

217    Tag: blume-20040923-envvars
218    Description:
219    
220    1. Changed definition of type ControlRegistry.registry_tree to
221       include control_info (i.e., the name of the controlling environment
222       variable).
223    
224    2. Added command-line flags -e and -E to print the names of environment
225       variables that can be used to control internal settings.
226       (This uses the new API mentioned in 1.)
