18		Tag: blume-20021010-ppc-divs
19		Description:
20
21		The mltree operator DIVS must be implemented with an overflow check on
22		the PPC because the hardware indicates divide-by-zero using "overflow" as
23		well.

28		Tag: blume-20020723-smlnj-home
29		Description:
30
31		Sml now senses the SMLNJ_HOME environment variable.  If this is set,
32		then the bin dir is assumed to be in $SMLNJ_HOME/bin and (unless
33		CM_PATHCONFIG is also set), the path configuration file is assumed
34		to be in $SMLNJ_HOME/lib/pathconfig.  This way one can easily move
35		the entire tree to some other place and everything will "just work".
36
37		(Companion commands such as ml-build and ml-makedepend also sense this
38		variable.)

43		Tag: blume-20020712-liveness
44		Description:
45
46		Exported two useful "step" functions from liveness module (MLRISC).

51		Tag: Release_110_41
52		Description:
53
54		New working release.  New bootfiles.

59		Tag: blume-20020705-btimp
60		Description:
61
62		Exported structure BTImp from $smlnj/viscomp/debugprof.cm so that
63		other clients can set up backtracing support.

67		Date: 2002/06/25 17:23:00 EDT
68		Tag: blume-20020625-fpmax
69		Description:
70
71		Fixed a bug in translation of INLMAX (and INLMIN) for the floating-point
72		case.  (The sense of the isNaN test was reversed -- which made min and
73		max always return their first argument.)

77		Date: 2002/06/11
78		Tag: blume-20020611-unixpath
79		Description:
80
81		Back-ported OS.Path.{from,to}UnixPath from idlbasis-devel branch.

85		Date: 2002/06/10 16:35:00 EDT
86		Tag: blume-20020610-ieeereal
87		Description:
88
89		I back-ported my implementation of IEEEReal.fromString from the
90		idlbasis-devel branch so that we can test it.
91
92		Another small change is that ppDec tries to give more information
93		than just "<sig>" in the case of functors.  However, this code is
94		broken in some mysterious way if the functor's body's signature
95		has not been declared by ascription but gets inferred from the
96		implementation.  This needs fixing...

101		Tag: blume-20020531-btrace-mode
102		Description:
103
104		Resurrected SMLofNJ.Internals.BTrace.mode.  (It accidentally fell by
105		the wayside when I switched over to using Controls everywhere.)

111		Description:
112
113		Labels are now displayed in the graphical output to make
114		the fall-through and target blocks obvious.

119		Tag: blume-20020522-shrink
120		Description:
121
122		John tweaked yesterday's fix for 1131 to handle an out-of-memory
123		situation that comes up when allocating huge arrays.
124

126		Name: Matthias Blume
127		Date: 2002/05/21 16:00:00 EDT

129		Description:
130
131		New working release (110.40).  New bootfiles.
132
133		[Also: John Reppy fixed GC bug 1131.]

144		Name: Matthias Blume
145		Date: 2002/05/21 10:55:00 EDT
146		Tag: blume-20020521-misc
147		Description:
148
149		- John tweaked runtime to be silent on heap export (except when
150		GC messages are on).
151		- I added a few more things (cross-compiling versions of CMB) to
152		config/preloads (as suggestions).
153

155		Name: Matthias Blume
156		Date: 2002/05/20 22:25:00 EDT
157		Tag: blume-20020520-controls
158		Description:
159
160		- Added ControlUtil structure to control-lib.cm.
161		- Use it throughout.
162		- Used Controls facility to define MLRISC controls (as opposed to
163		registering MLRISC control ref cells with Controls after the fact)
164		- Fixed messed-up controls priorities.
165
166		* Removed again all the stuff from config/preloads that one wouldn't
167		be able to preload at the time the initial heap image is built.
168		(Many libraries, e.g., CML, do not exist yet at this time.  The
169		only libraries that can be preloaded via config/preloads are those
170		that come bundled with the bootfiles.)

175		Tag: blume-20020520-preloads
176		Description:
177
178		Added a lot of commented-out suggestions for things to be included
179		in config/preloads.

184		Tag: leunga-20020518-mdl
185		Description:
186
187		o Made the mdl tool stuff compile and run again.
188		o I've disabled all the stuff that depends on RTL specifications; they
189		are all badly broken anyway.

192		Name: Matthias Blume
193		Date: 2002/05/17 16:49:00 EDT
194		Tag: blume-20020517-controls
195		Description:
196
197		0. John Reppy made several modifications to the SML/NJ library.
198		In particular, there is a shiny new controls-lib.cm.
199
200		1. Pushed new controls interface through compiler so that everything
201		compiles again.
202
203		2. Added FormatComb and FORMAT_COMB to the CML version of the
204		SML/NJ library (so that CML compiles again).
205
206		3. Modified init scripts because XXX_DEFAULT environment variables
207		are no longer with us.  (Boot-time initialization is now done
208		using the same environment variables that are also used for
209		startup-time initialization of controls.)

213		Date: 2002/05/15 09:20:10 EDT
214		Tag: george-20020515-pseudo-op-decls
215		Description:
216
217		All pseudo-ops emitted before the first segment declaration
218		such as TEXT, DATA, and BSS directives are assumed to be global
219		declarations and are emitted first in the assembly file. This is
220		useful in a number of situations where one has pseudo-ops that are not
221		specific to any segment, and also works around the constraint that one
222		cannot have client pseudo-ops in the TEXT segment.
223
224		Because no segment is associated with these declarations it is
225		an error to allocate any space or objects before the first segment
226		directive and an exception will be raised. However, we cannot make
227		this check for client pseudo-ops.
228
229		These top level declarations are a field in the CFG graph_info.
230		In theory you can continue to add to this field after the CFG has been
231		built -- provided you know what you are doing;-)

234		Name: Matthias Blume
235		Date: 2002/05/13 16:40:00 EDT
236		Tag: blume-20020513-pp-etc
237		Description:
238
239		A few minor bugfixes:
240
241		- Stopgap measure for bug recently reported by Elsa Gunter (ppDec).
242		(Bogus printouts for redefined bindings still occur.  Compiler
243		bug should no longer occur now.  We need to redo the prettyprinter
244		from scratch.)
245
246		- CM pathname printer now also adds escape sequences for ( and )
247
248		- commend and docu fixes for ml-nlffi

251		Name: Matthias Blume
252		Date: 2002/05/10 16:40:00 EDT
253		Tag: blume-20020510-erg-textio
254		Description:
255
256		Applied the following bugfix provided by Emden Gansner:
257
258		Output is corrupted when outputSubstr is used rather than output.
259
260		The problem occurs when a substring
261
262		ss = (s, dataStart, dataLen)
263
264		where dataStart > 0, fills a stream buffer with avail bytes left.
265		avail bytes of s, starting at index dataStart, are copied into the
266		buffer, the buffer is flushed, and then the remaining dataLen-avail
267		bytes of ss are copied into the beginning of the buffer. Instead of
268		starting this copy at index dataStart+avail in s, the current code
269		starts the copy at index avail.
270
271		Fix:
272		In text-io-fn.sml, change line 695 from
273		val needsFlush = copyVec(v, avail, dataLen-avail, buf, 0)
274		to
275		val needsFlush = copyVec(v, dataStart+avail, dataLen-avail, buf, 0)

278		Name: Matthias Blume
279		Date: 2002/04/12 13:55:00 EDT
280		Tag: blume-20020412-assyntax
281		Description:
282
283		1. Grabbed newer assyntax.h from the XFree86 project.
284		2. Fiddled with how to compile X86.prim.asm without warnings.
285		3. (Very) Minor cleanup in CM.
