26    Tag: Release_110_42
27    Description:
28    
29    In good old tradition, there has been a slight hiccup so that we have
30    to patch 110.42 after the fact.   The old release tag has been replaced
31    (see below).
32    
33    The change solves a problem with two competing approaches the
34    configuration problem regarding MacOS 10.1 vs. MacOS 10.2 which got in
35    each other's way.
36    
37    This change only affects the runtime system code and the installer script.
38    (No new bootfiles.)

52    Description:
53    
54    The mltree operator DIVS must be implemented with an overflow check on
55    the PPC because the hardware indicates divide-by-zero using "overflow" as
56    well.

61    Tag: blume-20020723-smlnj-home
62    Description:
63    
64    Sml now senses the SMLNJ_HOME environment variable.  If this is set,
65    then the bin dir is assumed to be in $SMLNJ_HOME/bin and (unless
66    CM_PATHCONFIG is also set), the path configuration file is assumed
67    to be in $SMLNJ_HOME/lib/pathconfig.  This way one can easily move
68    the entire tree to some other place and everything will "just work".
69    
70    (Companion commands such as ml-build and ml-makedepend also sense this
71    variable.)

93    Description:
94    
95    Exported structure BTImp from $smlnj/viscomp/debugprof.cm so that
96    other clients can set up backtracing support.

101    Tag: blume-20020625-fpmax
102    Description:
103    
104    Fixed a bug in translation of INLMAX (and INLMIN) for the floating-point
105    case.  (The sense of the isNaN test was reversed -- which made min and
106    max always return their first argument.)

119    Tag: blume-20020610-ieeereal
120    Description:
121    
122    I back-ported my implementation of IEEEReal.fromString from the
123    idlbasis-devel branch so that we can test it.
124    
125    Another small change is that ppDec tries to give more information
126    than just "<sig>" in the case of functors.  However, this code is
127    broken in some mysterious way if the functor's body's signature
128    has not been declared by ascription but gets inferred from the
129    implementation.  This needs fixing...

136    
137    Resurrected SMLofNJ.Internals.BTrace.mode.  (It accidentally fell by
138    the wayside when I switched over to using Controls everywhere.)

156    situation that comes up when allocating huge arrays.

180    Description:
181    
182    - John tweaked runtime to be silent on heap export (except when
183      GC messages are on).
184    - I added a few more things (cross-compiling versions of CMB) to
185      config/preloads (as suggestions).

190    Tag: blume-20020520-controls
191    Description:
192    
193    - Added ControlUtil structure to control-lib.cm.
194    - Use it throughout.
195    - Used Controls facility to define MLRISC controls (as opposed to
196      registering MLRISC control ref cells with Controls after the fact)
197    - Fixed messed-up controls priorities.
198    
199    * Removed again all the stuff from config/preloads that one wouldn't
200      be able to preload at the time the initial heap image is built.
201      (Many libraries, e.g., CML, do not exist yet at this time.  The
202       only libraries that can be preloaded via config/preloads are those
203       that come bundled with the bootfiles.)

210    
211    Added a lot of commented-out suggestions for things to be included
212    in config/preloads.

218    Description:
219    
220    o Made the mdl tool stuff compile and run again.
221    o I've disabled all the stuff that depends on RTL specifications; they
222      are all badly broken anyway.

227    Tag: blume-20020517-controls
228    Description:
229    
230    0. John Reppy made several modifications to the SML/NJ library.
231       In particular, there is a shiny new controls-lib.cm.
232    
233    1. Pushed new controls interface through compiler so that everything
234       compiles again.
235    
236    2. Added FormatComb and FORMAT_COMB to the CML version of the
237       SML/NJ library (so that CML compiles again).
238    
239    3. Modified init scripts because XXX_DEFAULT environment variables
240       are no longer with us.  (Boot-time initialization is now done
241       using the same environment variables that are also used for
242       startup-time initialization of controls.)

247    Tag: george-20020515-pseudo-op-decls
248    Description:
249    
250            All pseudo-ops emitted before the first segment declaration
251    such as TEXT, DATA, and BSS directives are assumed to be global
252    declarations and are emitted first in the assembly file. This is
253    useful in a number of situations where one has pseudo-ops that are not
254    specific to any segment, and also works around the constraint that one
255    cannot have client pseudo-ops in the TEXT segment.
256    
257            Because no segment is associated with these declarations it is
258    an error to allocate any space or objects before the first segment
259    directive and an exception will be raised. However, we cannot make
260    this check for client pseudo-ops.
261    
262            These top level declarations are a field in the CFG graph_info.
263    In theory you can continue to add to this field after the CFG has been
264    built -- provided you know what you are doing;-)

269    Tag: blume-20020513-pp-etc
270    Description:
271    
272    A few minor bugfixes:
273    
274      - Stopgap measure for bug recently reported by Elsa Gunter (ppDec).
275        (Bogus printouts for redefined bindings still occur.  Compiler
276        bug should no longer occur now.  We need to redo the prettyprinter
277        from scratch.)
278    
279      - CM pathname printer now also adds escape sequences for ( and )
280    
281      - commend and docu fixes for ml-nlffi

286    Tag: blume-20020510-erg-textio
287    Description:
288    
289    Applied the following bugfix provided by Emden Gansner:
290    
291        Output is corrupted when outputSubstr is used rather than output.
292    
293        The problem occurs when a substring
294    
295            ss = (s, dataStart, dataLen)
296    
297        where dataStart > 0, fills a stream buffer with avail bytes left.
298        avail bytes of s, starting at index dataStart, are copied into the
299        buffer, the buffer is flushed, and then the remaining dataLen-avail
300        bytes of ss are copied into the beginning of the buffer. Instead of
301        starting this copy at index dataStart+avail in s, the current code
302        starts the copy at index avail.
303    
304        Fix:
305        In text-io-fn.sml, change line 695 from
306             val needsFlush = copyVec(v, avail, dataLen-avail, buf, 0)
307        to
308             val needsFlush = copyVec(v, dataStart+avail, dataLen-avail, buf, 0)
