92		Tag: blume-20000831-cvsbootfiles
93		Description:

109		Tag: leunga-20000807-a-whole-bunch-of-stuff
110
111		Moby, C--, SSA, x86, machine descriptions etc.  Should only affect C--
112		and Mobdy.
113
114		1.  x86
115
116		a.  Fixes to peephole module by John and Dan.
117		b.  Assembly fix to SETcc by Allen.
118		c.  Fix to c-call by John.
119		d.  Fix to spilling by John.  (This one deals with the missing FSTPT case)
120		e.  Instruction selection optimization to SETcc as suggested by John.
121
122		For example,
123
124		MV(32, x, COND(32, CMP(32, LT, a, b), LI 1, LI 0))
125
126		should generate:
127
128		MOVL a, x
129		SUBL b, x
130		SHRL 31, x
131
132		2.  IR stuff
133
134		A bunch of new DJ-graph related algorithms added.  These
135		speed up SSA construction.
136
137		3.  SSA + Scheduling
138
139		Added code for SSA and scheduling to the repository

145		Tag: lal-20000727-linux-ppc
146		Description:
147
148		Made changes to support Linux PPC.
149		p.s. I have confirmation that the 110.29 boot files work fine.

154		Tag: blume-20000727-scripts
155		Description:
156
157		!!!! WARNING !!!!
158		You must recompile the runtime system!
159		!!!! WARNING !!!!
160
161		This is basically another round of script-enhancements:
162
163		1. sml, ml-build, and ml-makedepend accept options -D and -U to define
164		and undefine CM preprocessor symbols.
165
166		2. ml-build avoids generating a new heap image if it finds that the
167		existing one is still ok.  (The condition is that no ML file had to
168		be recompiled and all ML files are found to be older that the heap
169		file.)
170
171		To make this work smoothly, I also hacked the runtime system as
172		well as SMLofNJ.SysInfo to get access to the heap image suffix
173		(.sparc-solaris, ...) that is currently being used.
174
175		Moreover, the signature of CM.mk_standalone has changed.  See the
176		CM manual.
177
178		3. ml-makedepend accepts additional options -n, -a, and -o.  (See the
179		CM manual for details.)
180
181		4. More CM manual updates:
182		- all of the above has been documented.
183		- there is now a section describing the (CM-related) command line
184		arguments that are accepted by the "sml" command
185

187		Name: Matthias Blume
188		Date: 2000/07/25 16:20:00 JST
189		Tag: blume-20000725-makedepend
190		Description:
191
192		Added a script called ml-makedepend.  This can be used in makefiles
193		for Unix' make in a way very similar to the "makedepend" command for
194		C.
195
196		The script internally uses function CM.sources.
197
198		Synopsis:
199
200		ml-makedepend [-f makefile] cmfile targetname
201
202		The default for the makefile is "makefile" (or "Makefile" should
203		"makefile" not exist).
204
205		ml-makedepend adds a cmfile/targetname-specific section to this
206		makefile (after removing the previous version of this section).  The
207		section contains a single dependency specification with targetname on
208		the LHS (targetname is an arbitrary name), and a list of files derived
209		from the cmfile on the RHS.  Some of the files on the RHS are
210		ARCH/OPSYS-specific.  Therefore, ml-makedepend inserts references to
211		"make" variables $(ARCH) and $(OPSYS) in place of the corresponding
212		path names.  The makefile writer is responsible for making sure that
213		these variables have correct at the time "make" is invoked.
