18		Tag: Release_110_42
19		Description:
20
21		In good old tradition, there has been a slight hiccup so that we have
22		to patch 110.42 after the fact.   The old release tag has been replaced
23		(see below).
24
25		The change solves a problem with two competing approaches the
26		configuration problem regarding MacOS 10.1 vs. MacOS 10.2 which got in
27		each other's way.
28
29		This change only affects the runtime system code and the installer script.
30		(No new bootfiles.)

37

43		Tag: blume-20021010-ppc-divs
44		Description:
45
46		The mltree operator DIVS must be implemented with an overflow check on
47		the PPC because the hardware indicates divide-by-zero using "overflow" as
48		well.

53		Tag: blume-20020723-smlnj-home
54		Description:
55
56		Sml now senses the SMLNJ_HOME environment variable.  If this is set,
57		then the bin dir is assumed to be in $SMLNJ_HOME/bin and (unless
58		CM_PATHCONFIG is also set), the path configuration file is assumed
59		to be in $SMLNJ_HOME/lib/pathconfig.  This way one can easily move
60		the entire tree to some other place and everything will "just work".
61
62		(Companion commands such as ml-build and ml-makedepend also sense this
63		variable.)

68		Tag: blume-20020712-liveness
69		Description:
70
71		Exported two useful "step" functions from liveness module (MLRISC).

84		Tag: blume-20020705-btimp
85		Description:
86
87		Exported structure BTImp from $smlnj/viscomp/debugprof.cm so that
88		other clients can set up backtracing support.

93		Tag: blume-20020625-fpmax
94		Description:
95
96		Fixed a bug in translation of INLMAX (and INLMIN) for the floating-point
97		case.  (The sense of the isNaN test was reversed -- which made min and
98		max always return their first argument.)

102		Date: 2002/06/11
103		Tag: blume-20020611-unixpath
104		Description:
105
106		Back-ported OS.Path.{from,to}UnixPath from idlbasis-devel branch.

111		Tag: blume-20020610-ieeereal
112		Description:
113
114		I back-ported my implementation of IEEEReal.fromString from the
115		idlbasis-devel branch so that we can test it.
116
117		Another small change is that ppDec tries to give more information
118		than just "<sig>" in the case of functors.  However, this code is
119		broken in some mysterious way if the functor's body's signature
120		has not been declared by ascription but gets inferred from the
121		implementation.  This needs fixing...

127		Description:
128
129		Resurrected SMLofNJ.Internals.BTrace.mode.  (It accidentally fell by
130		the wayside when I switched over to using Controls everywhere.)

136		Description:
137
138		Labels are now displayed in the graphical output to make
139		the fall-through and target blocks obvious.

145		Description:
146
147		John tweaked yesterday's fix for 1131 to handle an out-of-memory
148		situation that comes up when allocating huge arrays.

155
156		New working release (110.40).  New bootfiles.
157

165
166		CM documentation update.

169		Name: Matthias Blume
170		Date: 2002/05/21 10:55:00 EDT
171		Tag: blume-20020521-misc
172		Description:
173
174		- John tweaked runtime to be silent on heap export (except when
175		GC messages are on).
176		- I added a few more things (cross-compiling versions of CMB) to
177		config/preloads (as suggestions).
178
179		----------------------------------------------------------------------
180		Name: Matthias Blume
181		Date: 2002/05/20 22:25:00 EDT
182		Tag: blume-20020520-controls
183		Description:
184
185		- Added ControlUtil structure to control-lib.cm.
186		- Use it throughout.
187		- Used Controls facility to define MLRISC controls (as opposed to
188		registering MLRISC control ref cells with Controls after the fact)
189		- Fixed messed-up controls priorities.
190
191		* Removed again all the stuff from config/preloads that one wouldn't
192		be able to preload at the time the initial heap image is built.
193		(Many libraries, e.g., CML, do not exist yet at this time.  The
194		only libraries that can be preloaded via config/preloads are those
195		that come bundled with the bootfiles.)
196

198		Name: Matthias Blume
199		Date: 2002/05/20 10:59:00 EDT
200		Tag: blume-20020520-preloads
201		Description:
202
203		Added a lot of commented-out suggestions for things to be included
204		in config/preloads.

208		Date: 2002/05/18 14:20:00 EDT
209		Tag: leunga-20020518-mdl
210		Description:
211
212		o Made the mdl tool stuff compile and run again.
213		o I've disabled all the stuff that depends on RTL specifications; they
214		are all badly broken anyway.
215

217		Name: Matthias Blume
218		Date: 2002/05/17 16:49:00 EDT
219		Tag: blume-20020517-controls
220		Description:
221
222		0. John Reppy made several modifications to the SML/NJ library.
223		In particular, there is a shiny new controls-lib.cm.
224
225		1. Pushed new controls interface through compiler so that everything
226		compiles again.
227
228		2. Added FormatComb and FORMAT_COMB to the CML version of the
229		SML/NJ library (so that CML compiles again).
230
231		3. Modified init scripts because XXX_DEFAULT environment variables
232		are no longer with us.  (Boot-time initialization is now done
233		using the same environment variables that are also used for
234		startup-time initialization of controls.)
235

238		Date: 2002/05/15 09:20:10 EDT
239		Tag: george-20020515-pseudo-op-decls
240		Description:
241
242		All pseudo-ops emitted before the first segment declaration
243		such as TEXT, DATA, and BSS directives are assumed to be global
244		declarations and are emitted first in the assembly file. This is
245		useful in a number of situations where one has pseudo-ops that are not
246		specific to any segment, and also works around the constraint that one
247		cannot have client pseudo-ops in the TEXT segment.
248
249		Because no segment is associated with these declarations it is
250		an error to allocate any space or objects before the first segment
251		directive and an exception will be raised. However, we cannot make
252		this check for client pseudo-ops.
253
254		These top level declarations are a field in the CFG graph_info.
255		In theory you can continue to add to this field after the CFG has been
256		built -- provided you know what you are doing;-)

260		Date: 2002/05/13 16:40:00 EDT
261		Tag: blume-20020513-pp-etc
262		Description:
263
264		A few minor bugfixes:
265
266		- Stopgap measure for bug recently reported by Elsa Gunter (ppDec).
267		(Bogus printouts for redefined bindings still occur.  Compiler
268		bug should no longer occur now.  We need to redo the prettyprinter
269		from scratch.)
270
271		- CM pathname printer now also adds escape sequences for ( and )
272
273		- commend and docu fixes for ml-nlffi

276		Name: Matthias Blume
277		Date: 2002/05/10 16:40:00 EDT
278		Tag: blume-20020510-erg-textio
279		Description:
280
281		Applied the following bugfix provided by Emden Gansner:
282
283		Output is corrupted when outputSubstr is used rather than output.
284
285		The problem occurs when a substring
286
287		ss = (s, dataStart, dataLen)
288
289		where dataStart > 0, fills a stream buffer with avail bytes left.
290		avail bytes of s, starting at index dataStart, are copied into the
291		buffer, the buffer is flushed, and then the remaining dataLen-avail
292		bytes of ss are copied into the beginning of the buffer. Instead of
293		starting this copy at index dataStart+avail in s, the current code
294		starts the copy at index avail.
295
296		Fix:
297		In text-io-fn.sml, change line 695 from
298		val needsFlush = copyVec(v, avail, dataLen-avail, buf, 0)
299		to
300		val needsFlush = copyVec(v, dataStart+avail, dataLen-avail, buf, 0)
