37		Description:
38
39		- John tweaked runtime to be silent on heap export (except when
40		GC messages are on).
41		- I added a few more things (cross-compiling versions of CMB) to
42		config/preloads (as suggestions).

47		Tag: blume-20020520-controls
48		Description:
49
50		- Added ControlUtil structure to control-lib.cm.
51		- Use it throughout.
52		- Used Controls facility to define MLRISC controls (as opposed to
53		registering MLRISC control ref cells with Controls after the fact)
54		- Fixed messed-up controls priorities.
55
56		* Removed again all the stuff from config/preloads that one wouldn't
57		be able to preload at the time the initial heap image is built.
58		(Many libraries, e.g., CML, do not exist yet at this time.  The
59		only libraries that can be preloaded via config/preloads are those
60		that come bundled with the bootfiles.)

66		Description:
67
68		Added a lot of commented-out suggestions for things to be included
69		in config/preloads.

75		Description:
76
77		o Made the mdl tool stuff compile and run again.
78		o I've disabled all the stuff that depends on RTL specifications; they
79		are all badly broken anyway.

84		Tag: blume-20020517-controls
85		Description:
86
87		0. John Reppy made several modifications to the SML/NJ library.
88		In particular, there is a shiny new controls-lib.cm.
89
90		1. Pushed new controls interface through compiler so that everything
91		compiles again.
92
93		2. Added FormatComb and FORMAT_COMB to the CML version of the
94		SML/NJ library (so that CML compiles again).
95
96		3. Modified init scripts because XXX_DEFAULT environment variables
97		are no longer with us.  (Boot-time initialization is now done
98		using the same environment variables that are also used for
99		startup-time initialization of controls.)

104		Tag: george-20020515-pseudo-op-decls
105		Description:
106
107		All pseudo-ops emitted before the first segment declaration
108		such as TEXT, DATA, and BSS directives are assumed to be global
109		declarations and are emitted first in the assembly file. This is
110		useful in a number of situations where one has pseudo-ops that are not
111		specific to any segment, and also works around the constraint that one
112		cannot have client pseudo-ops in the TEXT segment.
113
114		Because no segment is associated with these declarations it is
115		an error to allocate any space or objects before the first segment
116		directive and an exception will be raised. However, we cannot make
117		this check for client pseudo-ops.
118
119		These top level declarations are a field in the CFG graph_info.
120		In theory you can continue to add to this field after the CFG has been
121		built -- provided you know what you are doing;-)

125		Date: 2002/05/13 16:40:00 EDT
126		Tag: blume-20020513-pp-etc
127		Description:
128
129		A few minor bugfixes:
130
131		- Stopgap measure for bug recently reported by Elsa Gunter (ppDec).
132		(Bogus printouts for redefined bindings still occur.  Compiler
133		bug should no longer occur now.  We need to redo the prettyprinter
134		from scratch.)
135
136		- CM pathname printer now also adds escape sequences for ( and )
137
138		- commend and docu fixes for ml-nlffi

141		Name: Matthias Blume
142		Date: 2002/05/10 16:40:00 EDT
143		Tag: blume-20020510-erg-textio
144		Description:
145
146		Applied the following bugfix provided by Emden Gansner:
147
148		Output is corrupted when outputSubstr is used rather than output.
149
150		The problem occurs when a substring
151
152		ss = (s, dataStart, dataLen)
153
154		where dataStart > 0, fills a stream buffer with avail bytes left.
155		avail bytes of s, starting at index dataStart, are copied into the
156		buffer, the buffer is flushed, and then the remaining dataLen-avail
157		bytes of ss are copied into the beginning of the buffer. Instead of
158		starting this copy at index dataStart+avail in s, the current code
159		starts the copy at index avail.
160
161		Fix:
162		In text-io-fn.sml, change line 695 from
163		val needsFlush = copyVec(v, avail, dataLen-avail, buf, 0)
164		to
165		val needsFlush = copyVec(v, dataStart+avail, dataLen-avail, buf, 0)

169		Date: 2002/04/12 13:55:00 EDT
170		Tag: blume-20020412-assyntax
171		Description:
172
173		1. Grabbed newer assyntax.h from the XFree86 project.
174		2. Fiddled with how to compile X86.prim.asm without warnings.
175		3. (Very) Minor cleanup in CM.
176
177		----------------------------------------------------------------------
178		Name: Matthias Blume
179		Date: 2002/04/01 (no joke!) 17:07:00 EST
180		Tag: blume-20020401-x86div
181		Description:
182
183		Added full support for div/mod/rem/quot on the x86, using the machine
184		instruction's two results (without clumsily recomputing the remainder)
185		directly where appropriate.
186
187		Some more extensive power-of-two support was added to the x86 instruction
188		selector (avoiding expensive divs, mods, and muls where they can be
189		replaced with cheaper shifts and masks).  However, this sort of thing
190		ought to be done earlier, e.g., within the CPS optimizer so that
191		all architectures benefit from it.
192
193		The compiler compiles to a fixed point, but changes might be somewhat
194		fragile nevertheless.  Please, report any strange things that you might
195		see wrt. div/mod/quot/rem...
