19    Description:
20    
21    Some rationalization of names:
22    
23       structure BTrace -> structure TDPInstrument
24       etc.
25    
26    This is is preparation of using the original back-trace
27    instrumentation for other purposes.  "TDP" stands for
28    Trace/Debug/Profile.
29    
30    The control flag controlling whether instrumentation is on or off is now
31    registered under a different name, so instead of running sml as
32    
33     sml -Cinstrument.btrace-mode=true
34    
35    one has to say
36    
37     sml -Ctdp.instrument=true

43    Description:
44    
45    Made some minor modifications to elabcore.sml to have source regions
46    be propagated more tightly -- resulting in better (i.e., smaller)
47    regions being reported in error- and debug messages.

52    Tag: blume-20041008-cmkw
53    Description:
54    
55    Fixed handling of keywords in .cm files: After seeing "is" the lexer
56    treats subsequent occurrences of "group", "library", "source", "is",
57    "*", and "-" as ordinary identifiers rather than keywords.
58    
59    Most seriously, this fixes a problem with CM's "shell" tool.  The tool
60    is supposed to accept a tool argument called "source", but this did
61    not work because of the clash with the keyword.

67    Description:
68    
69    Assorted cleanup work:
70    
71      - got rid of intstrmap in favor of using the library's
72        hash table implementation
73      - threw out most of the pathnames stuff, as it was not used anyway
74      - simplified tokentable implementation
75      - fixed some minor spelling errors

81    Description:
82    
83    Cleaned up the absyn to reflect the invariant that HANDLE always
84    carries a FNexp as part of the type definition.  This eliminates some
85    superfluous sanity checks at runtime down the road.
86    
87    Some minor cleanup of the btrace code.

93    Description:
94    
95    Added hack to make slave mode work in the presence of the version
96    tool.  (Still, since the master does two passes over the code for
97    CMB.make, the release number gets bumped twice when slaves are
98    attached.  I don't know if this is worth fixing...)

104    Description:
105    
106    * Moved the "version" magic into its own little library under
107    src/system/smlnj/internal.  This avoids expensive reconstruction
108    of a stable src/compiler/core.cm.
109    
110    * At the same time, structure CompilerVersion is now known as structure
111    SMLNJVersion.
112    
113    * Arranged for the version tool to NOT kick in when rebuilding the system
114      (makeml -rebuild, fixpt).  Otherwise one would never reach a fixpoint.
115      Also, loading the versiontool does not work when rebuilding the system
116      because CM is not properly initialized at that time.

121    Tag: blume-20040929-autoversion
122    Description:
123    
124    Implemented some CM magic to have
125        file src/compiler/TopLevel/main/version.sml
126    generated automagically.
127    The version is taken from two files: config/version and config/release.
128    The first is expected to contain a two-part version number such as 110.49.
129    The second should contain a single number, but it may be missing.
130    
131    If the environment variable VERSIONTOOL_BUMP_RELEASE is defined at the
132    time the version tool is loaded (which is the first time you say CMB.make),
133    then the tool will increment the value stored in config/release every
134    time CMB.make is invoked.
135    
136    The binfile format is now insensitive to anything beyond the first
137    two components of a version number, so bumping the release does not render
138    binfiles incompatible.  Auto-bumping can be used to keep track of versions
139    during development without invalidating existing binfiles.
140    
141    In any case, every CMB.make updates the date information in version.sml.
142    (This is the date that is printed in the banner.)

149    
150    Some cleanup of the controls code.

155    Tag: blume-20040927-controls
156    Description:
157    
158    Added two pieces of functionality to the Controls interface:
159    
160    1.   val save'restore: 'a control -> unit -> unit
161    
162       grabs the current value of the control in stage 1 and restores it
163       in stage 2.
164    
165    2.   val set' : 'a control * 'a -> unit -> unit
166    
167       stores the given value into the control in stage 2 (i.e., delayed)
168       but does all error checking in stage 1.
169       (This is for string controls that need to do parse their argument --
170        something that might fail.  In some cases, notably in CM, one
171        already knows the intended argument but wants to delay the actual
172        assignment until a time when error recovery would be more difficult.)
173    
174    Changed the handling of controls in tool arguments to classes "sml" and
175    "lazysml":
176       - use Controls.save'restore as a more robust way of restoring the
177         old value (in particular: without having to re-parse the string)
178       - use controls to handle the "overload" keyword in the init group
179         (I believe this change actually fixes a long-standing obscure bug.)
180

184    Tag: blume-20040927-lazysml
185    Description:
186    
187    Added a new tool class called "lazysml" to CM's tool chest.  The only
188    difference to "sml" is that compilation is done with Control.lazysml
189    set to true.  A source of class "lazysml" is automatically recognized
190    by a file name suffix of ".lml".
191    
192    In addition to the above feature, the original class "sml" now also
193    supports a tool argument "lazy" which has the same effect.  As a
194    result, the following three lines are equivalent:
195    
196        foo.sml : lazysml
197        foo.sml : sml (lazy)
198        foo.sml (lazy)
199    
200    The setting goes into effect both during parsing and during
201    compilation.  The original setting is restored right after parsing and
202    after compilation, respectively.
203    
204    In addition to all the above, there is also a general mechanism to set
205    ANY of the "controls" that are available at the command line via
206    "-C..." on a per-sml-file basis.  The same rules that apply for "lazy"
207    apply as well. (In fact, "lazy" is implemented as a special case of
208    the general mechanism.)
209    
210    The .cm file syntax uses a new keyword tool argument called "with".
211    There are several ways of indicating the desired settings:
212    
213        foo.sml (with:parser.quotations=true)
214        foo.sml (with:(name:parser.quotations value:true))
215        foo.sml (with:(name:name1 value:value1 name:name2 value:value2 ...))
216        foo.sml (with:(name1=value1 name2=value2 ...))
217        foo.sml (with:(name1=value1 name:name2 value:value2 name3=value3 ...))
218    
219        etc.
220    
221    Another possible abbreviation is to leave out the =v or value:v part
222    if the name refers to a boolean control (in which case the value is
223    taken to be true).  Thus, one could get lazy sml also by saying:
224    
225        foo.sml (with:parser.lazy-keyword=true)
226        foo.sml (with:parser.lazy-keyword)
227        foo.sml (with:(name:parser.lazy-keyword value:true))
228        foo.sml (with:(name:parser.lazy-keyword))

235    
236    Turned message about "emiting long form of branch" off by default.
237    Added a control flag to turn it back on when desired.
