39    More error message grief: Where there used to be no messages, there

46    Description:
47    
48    I made a version 110.29.1 with new bootfiles.
49    
50    Changes:  Modified pickler/unpickler for faster and leaner unpickling.
51              CM documentation changes and a small bugfix in CM's error reporting.

57    Description:
58    
59    Changed the type of the nodestatus, so that:
60    
61            SPILLED(~1)             is now SPILLED
62            SPILLED(m) where m>=0   is now MEMREG(m)
63            SPILLED(s) where s<~1   is now SPILL_LOC(~s)

77    Description:
78    
79    New URL for boot files (because the 110.29 files on the BL server do
80    now work correctly with my updated install scripts for yacc and lex).

94    
95      Moby, C--, SSA, x86, machine descriptions etc.  Should only affect C--
96    and Mobdy.
97    
98    1.  x86
99    
100       a.  Fixes to peephole module by John and Dan.
101       b.  Assembly fix to SETcc by Allen.
102       c.  Fix to c-call by John.
103       d.  Fix to spilling by John.  (This one deals with the missing FSTPT case)
104       e.  Instruction selection optimization to SETcc as suggested by John.
105    
106           For example,
107    
108            MV(32, x, COND(32, CMP(32, LT, a, b), LI 1, LI 0))
109    
110           should generate:
111    
112            MOVL a, x
113            SUBL b, x
114            SHRL 31, x
115    
116    2.  IR stuff
117    
118         A bunch of new DJ-graph related algorithms added.  These
119         speed up SSA construction.
120    
121    3.  SSA + Scheduling
122    
123         Added code for SSA and scheduling to the repository

131    
132     Made changes to support Linux PPC.
133     p.s. I have confirmation that the 110.29 boot files work fine.

138    Tag: blume-20000727-scripts
139    Description:
140    
141    !!!! WARNING !!!!
142    You must recompile the runtime system!
143    !!!! WARNING !!!!
144    
145    This is basically another round of script-enhancements:
146    
147    1. sml, ml-build, and ml-makedepend accept options -D and -U to define
148       and undefine CM preprocessor symbols.
149    
150    2. ml-build avoids generating a new heap image if it finds that the
151       existing one is still ok.  (The condition is that no ML file had to
152       be recompiled and all ML files are found to be older that the heap
153       file.)
154    
155       To make this work smoothly, I also hacked the runtime system as
156       well as SMLofNJ.SysInfo to get access to the heap image suffix
157       (.sparc-solaris, ...) that is currently being used.
158    
159       Moreover, the signature of CM.mk_standalone has changed.  See the
160       CM manual.
161    
162    3. ml-makedepend accepts additional options -n, -a, and -o.  (See the
163       CM manual for details.)
164    
165    4. More CM manual updates:
166        - all of the above has been documented.
167        - there is now a section describing the (CM-related) command line
168          arguments that are accepted by the "sml" command

173    Tag: blume-20000725-makedepend
174    Description:
175    
176    Added a script called ml-makedepend.  This can be used in makefiles
177    for Unix' make in a way very similar to the "makedepend" command for
178    C.
179    
180    The script internally uses function CM.sources.
181    
182    Synopsis:
183    
184        ml-makedepend [-f makefile] cmfile targetname
185    
186    The default for the makefile is "makefile" (or "Makefile" should
187    "makefile" not exist).
188    
189    ml-makedepend adds a cmfile/targetname-specific section to this
190    makefile (after removing the previous version of this section).  The
191    section contains a single dependency specification with targetname on
192    the LHS (targetname is an arbitrary name), and a list of files derived
193    from the cmfile on the RHS.  Some of the files on the RHS are
194    ARCH/OPSYS-specific.  Therefore, ml-makedepend inserts references to
195    "make" variables $(ARCH) and $(OPSYS) in place of the corresponding
196    path names.  The makefile writer is responsible for making sure that
197    these variables have correct at the time "make" is invoked.
