33    Description:
34    
35    A new noweb tool has been added.  The existing system is entirely
36    unaffected by this, but some CM users have asked for renewed noweb
37    support.  Everything is documented in the CM manual.
38    
39    New (plugin) libraries:
40    
41       noweb-tool.cm
42       nw-ext.cm

65    Tag: blume-20000430-versions
66    Description:
67    
68    1. CM version numbering added.  This is an implementation of Lal's
69       proposal for adding version numbers and version checking to .cm
70       files.  Lal said that his proposal was just that -- a proposal.
71       For the time being I went ahead and implemented it so that people
72       can comment on it.  Everything is completely backward-compatible
73       (except for the stable library format, i.e., new bootfiles!).
74    
75       As usual, see the CM manual for details.
76    
77    2. An alternative syntax for anchored paths has been implemented.
78       Dave has recently voiced the same concerns that I had when I did
79       this, so there should be some support.  My take is that eventually
80       I will let support for the current syntax (where anchors are
81       "implicit") fade out in favor of the new, explicit syntax.
82       In order to be backward-compatible, both old and new syntax are
83       currently supported.
84    
85       Again, see the CM manual for details.
86    
87    3. Parallel make is trying to be slightly smarter:  When the master
88       process finds a "bottleneck", i.e., when there is only one
89       compilation unit that can be compiled and everybody else is
90       waiting on it, then it will simply compile it directly instead
91       of clumsily telling one of the slaves to do it.
92    
93    4. Support for "unsharing" added.  This is necessary in order to be
94       able to have two different versions of the same library running
95       at the same time (e.g., for trying out a new MLRISC while still
96       having the old MLRISC linked into the current compiler, etc.)
97       See the CM manual.
98    
99    5. Simple "makedepend" functionality added for generating Makefile
100       dependency information.  (This is rather crude at the moment.
101       Expect some changes here in the future.)
102    
103    6. ".fun" added as a recognized suffix for ML files. Also documented
104       explicitly in the manual that the fallback behavior (unknown suffix
105       -> ML file) is not an official feature!
106    
107    7. Small changes to the pickler for stable libraries.
108    
109    8. Several internal changes to CM (for cleanup/improvement).
110    
111    
112    !!!! NEW BINFILES !!!!

117    Tag: blume-20000428-pathconfig
118    Description:
119    
120    1. I changed config/install.sh to remove duplicate entries from the
121       lib/pathconfig file at the end.  Moreover, the final version of
122       lib/pathconfig is sorted alphabetically.  The same (sorting) is done
123       in src/system/installml.
124    
125    2. The config/install.sh script now consistently uses relative
126       pathnames in lib/pathconfig whenever the anchor is in the lib
127       directory.  (So far this was true for the libraries that come
128       pre-compiled and bundled as part of the bootfiles but not for
129       libraries that are compiled by the script itself.)

143    Description:
144    
145    1. Alpha
146    
147        PSEUDOARITH was missing in AlphaRewrite.  This causes an endless loop
148    in C--.
149    
150    2. RA
151    
152       Added a flag "ra-dump-size" to print out the size of the flowgraph
153       and the interference graph.

167    Tag: leunga-20000420-ssa-c---stuff
168    Description:
169    
170      This update synchronizes my repository with Yale's.  Most of these
171    changes, however, do not affect SML/NJ at all (the RA is an exception).
172    
173    1. Register Allocator
174    
175       a. An improvement in the interference graph construction:
176          Given a copy
177    
178                s <- t
179    
180          no interference edge between s and t is added for this definition of s.
181    
182       b. I've added two new spill heuristic modules that Fermin and I developed
183          (in the new library RA.cm). These are unused in SML/NJ but maybe
184          useful for others (Moby?)
185    
186    2. X86
187    
188       a. Various fixes in the backend provided by Fermin [C--] and Lal.
189    
190    3. Alpha
191    
192       a. Added the BSR instruction and code generation that goes with it [C--]
193       b. Other fixes too numerous to recount provided by Fermin [C--]
194    
195    4. Regmaps
196    
197       a. The regmaps are not initialized with the identity physical bindings
198          at creation time.  This is unneeded.
199    
200    5. MLRISC Optimizations
201    
202       a. The DJ-Graph module can now compute the iterated dominance frontiers
203          intersects with liveness incrementally in linear time! Woohoo!
204          This is now used in my new SSA construction algorithm.
205    
206       b. THe branch reorganization module is now smarter about linear chains of
207          basic blocks.
208

214    Description:
215    
216    Changed install.sh script to handle archive files without version number
217    and to use "boot.<arch>-<os>" instead of "sml.boot.<arch>-<os>" for the
218    name of the boot file archive.

246    Description:
247    
248    Improved handling of branches (mostly those generated from
249    polymorphic equality), removed switchoff and changed the
250    default optimization settings (more cpsopt and less flintopt).

277    
278    This update just merges three minor cosmetic updates to CM's sources
279    to get ready for the 110.27 code freeze on Friday.  No functionality
280    has changed.

285    Tag: leunga-20000404-x86-asm
286    Description:
287    
288    1.  Fixed a problem in X86 assembly.
289    
290        Things like
291    
292           jmp %eax
293           jmp (%eax)
294    
295        should be output as
296    
297           jmp *%eax
298           jmp *(%eax)
299    
300    2.  Assembly output
301    
302          Added a new flag
303    
304              "asm-indent-copies" (default to false)
305    
306          When this flag is on, parallel copies will be indented an extra level.

311    Tag: leunga-20000404-C--Moby
312    Description:
313    
314        All of these fixes are related to C--, Moby, and my own optimization
315        stuff; so they shouldn't affect SML/NJ.
316    
317    1.  X86
318    
319        Various fixes related floating point, and extensions.
320    
321    2.  Alpha
322    
323        Some extra patterns related to loads with signed/zero extension
324        provided by Fermin.
325    
326    3.  Assembly
327    
328        When generating assemby, resolve the value of client defined constants,
329        instead of generating symbolic values.  This is controlled by the
330        new flag "asm-resolve-constants", which is default to true.
331    
332    4.  Machine Descriptions
333    
334        a. The precedence parser was slightly broken when parsing infixr symbols.
335        b. The type generalizing code had the bound variables reversed, resulting
336           in a problem during arity raising.
337        c. Various fixes in machine descriptions.

342    Tag: blume_main_v110p26p2_2
343    Description:
344    
345    I eliminated coreEnv from compInfo.  Access to the "Core" structure is
346    now done via the ordinary static environment that is context to each
347    compilation unit.
348    
349    To this end, I arranged that instead of "structure Core" as "structure
350    _Core" is bound in the pervasive environment.  Core access is done via
351    _Core (which can never be accidentially rebound because _Core is not a
352    legal surface-syntax symbol).
353    
354    The current solution is much cleaner because the core environment is
355    now simply part of the pervasive environment which is part of every
356    compilation unit's context anyway.  In particular, this eliminates all
357    special-case handling that was necessary until now in order to deal
358    with dynamic and symbolic parts of the core environment.
359    
360    Remaining hackery (to bind the "magic" symbol _Core) is localized in the
361    compilation mananger's bootstrap compiler (actually: in the "init group"
362    handling).  See the comments in src/system/smlnj/init/init.cmi for
363    more details.
364    
365    I also tried to track down all mentions of "Core" (as string argument
366    to Symbol.strSymbol) in the compiler and replaced them with a
367    reference to the new CoreSym.coreSym.  Seems cleaner since the actual
368    name appears in one place only.
369    
370    Binfile and bootfile format have not changed, but the switchover from
371    the old "init.cmi" to the new one is a bit tricky, so I supplied new
372    bootfiles anyway.

387    Tag: leunga-20000331-aliasing
388    Description:
389    
390    This update contains a rewritten (and hopefully more correct) module
391    for extracting aliasing information from CPS.
392    
393       To turn on this feature:
394    
395            Compiler.Control.CG.memDisambiguate := true
396    
397       To pretty print the region information with assembly
398    
399           Compiler.Control.MLRISC.getFlag "asm-show-region" := true;
400    
401       To control how many levels of aliasing information are printed, use:
402    
403           Compiler.Control.MLRISC.getInt "points-to-show-level" := n
404    
405       The default of n is 3.
