28    
29    Minor bugfix in config/libinstall (set anchor with path to
30    standalone tool after installing it, otherwise libraries that
31    need ml-lex or ml-yacc won't compile the first time the installer
32    runs).

58    Description:
59    
60    Rewrote large parts of config/install.sh in SML (config/libinstall.sml).
61    Modified config/install.bat to take advantage of it.  Also modified
62    config/install.sh (and called it config/new-install.sh) to take advantage
63    of it on Unix systems.  (The SML code is (supposed to be) platform-
64    independent.)
65    
66    The installer can now install everything under Win32
67    as well as under *nix as long as it compiles.
68    
69    Other changes:
70    
71      - made CML compile again under Win32
72      - made eXene compile under Win32 (by providing a fake structure UnixSock
73        and by using OS.Process.getEnv instead of Posix.ProcEnv.getenv)
74      - fixed a bug in nowhere: it assumed that type OS.Process.status is the
75        same as type int;  under Win32 it isn't
76      - fixed some slice-related problems in the win32-specific parts of CML
77      - added a functor argument "sameVol" to os-path-fn.sml in the Basis
78        (under Win32, the volume name is case-insensitive, and the
79        OS.Path code compares volume names for equality)

85    Description:
86    
87    Made Win32 version of OS.FileSys.fullPath return current directory
88    when given an empty string.  This is what the spec says, and incidentally,
89    CM depends on it.  (CM otherwise goes into an infinite loop in certain
90    cases when presented with the name of a non-existing .cm file.)

95    Tag: blume-20030905-slices-etc
96    Description:
97    
98      1. Changed interface to vectors and arrays in Basis to match
99         (draft) Basis spec.
100      2. Added signatures and implementations of slices according to
101         Basis spec.
102      3. Edited source code throughout the system to make it compile again
103         under 1. and 2.  (In some cases code had to be added to have it
104         match the new signatures.)
105      4. MLRISC should be backward-compatible: the copies of the originals
106         of files that needed to change under 3. were retained, the .cm files
107         check the compiler version number and use old versions when
108         appropriate.
109      5. Changed type of OS.FileSys.readDir and Posix.FileSys.readdir to
110         dirstream -> string option (in accordance with Basis spec).
111      6. When generating code that counts lines, ml-lex used function
112         CharVector.foldli, taking advantage of its old interface.
113         This has been replaced with the corresponding code from
114         CharVectorSlice.  (html-lex must be re-lexed!)
115      7. BitArray in smlnj-lib/Util has been extended/modified to match the
116         new MONO_ARRAY signature.  (Do we need BitArraySlice?)
117      8. Removed temporary additions (fromInternal, toInternal) from the
118         (now obsolete) IntInf in smlnj-lib/Util.
119      9. Cleaned up structure Byte.
120     10. Added localOffset, scan, and fromString to Date (according to spec).
121         Cleaned/corrected implementation of Date.
122         (Still need to check for correctness; implement better canonicalizeDate.)
123     11. Added "scan" to signature IEEE_REAL.
124     12. Some improvements to IntInf [in particular: efficiency-hack for
125         mod and rem when second operand is 2 (for parity checks).]
126     13. Changed representation of type Time.time, using a single IntInf.int
127         value counting microseconds.  This considerably simplified the
128         implementation of structure Time.  We now support negative time
129         values; scan and fromString handle signs.
130     14. Functor PrimIO now takes two additional arguments (VectorSlice and
131         ArraySlice).

136    Tag: blume-20030828-intinf
137    Description:
138    
139    This is a major update which comes with a version number bump
140    (110.42.99 -- yes, we are really close to 110.43 :-), NEW BOOTFILES,
141    and an implementation of IntInf in the Basis.
142    
143    There are a fairly large number of related changes and updates throughout
144    the system:
145    
146    Basis:
147            - Implemented IntInf.
148            - Made LargeInt a projection of IntInf (by filtering through INTEGER).
149            - Added some missing Real64 operations, most notably Real.toLargeInt.
150            - Added FixedInt as a synonym for Int32.
151    
152    compiler:
153            * Added support for a built-in intinf type.
154              - literals
155              - pattern matching
156              - conversion shortcuts (Int32.fromLarge o Int.toLarge etc.)
157              - overloading on literals and operations
158    
159            This required adding a primitive type intinf, some additional
160            primops, and implementations for several non-trivial intinf
161            operations in Core.  (The intinf type is completely abstract
162            to the compiler; all operations get delegated back to the Core.)
163    
164            * Intinf equality is handled by polyequal.  However, the compiler
165            does not print its usual warning in this case (since polyequal
166            is the right thing to do there).
167    
168            * Improved the organization of structure InlineT.
169    
170            * A word about conversion primops:
171            If conversions involving intinf do not cancel out during
172            CPS contract, then the compiler must insert calls to Core functions.
173            Since all core access must be resolved already during the FLINT
174            translate phase, it would be too late a the time of CPS contract
175            to add new Core calls.  For this reason, conversion primops
176            for intinf carry two arguments:  1. the numeric argument that
177            they are supposed to convert, and 2. the Core function that
178            can help with this conversion if necessary.  If CPS contract
179            eliminates a primop, then the associated Core function becomes
180            dead and goes away.  Intinf conversion primops that do not get
181            eliminated by CPS contract get rewritten into calls of their
182            core functions by a separate, new phase.
183    
184    interactive system:
185            - Control.Print.intinfDepth controls max length of intinf constants
186            being printed. (Analogous to Control.Print.stringDepth.)
187            - Cleanup in printutil and pputil: got rid of unused stuff and
188            duplicates; replaced some of the code with code that makes better
189            use of library functionality.
190    
191    CM:
192            Bugfix: parse-errors in init group (system/smlnj/init/init.cmi)
193            are no longer silent.
194    
195    CKIT:
196            Fixed mismatched uses of Int32 and LargeInt.  I always decided
197            in favor of LargeInt -- which is now the same as IntInf.
198            CKIT-knowledgable people should check whether this is what's
199            intended and otherwise change things back to using Int32 or
200            FixedInt.
201    
202    Throughout the code:
203            Started using IntInf.int literals and built-in operations
204            (e.g., comparison with 0) where this seems appropriate.

211    Description:
212    
213    Merging changes from the mcz-branch development branch into trunk.
214    These changes involve replacement of the emulated old prettyprinter
215    interface with direct use of the SML/NJ Lib PP library, and fixing
216    of a couple of bugs (895, 1186) relating to error messages.  A new
217    prettyprinter for ast datatypes (Elaborator/print/ppast.{sig,sml})
218    has been added.

224    Description:
225    
226    Version number bumped to 110.42.9.  NEW BOOTFILES!!!
227    
228        http://smlnj.cs.uchicago.edu/dist/working/110.42.9/
229    
230    This patch restores SML/NJ's ability to run under win32.  There are a
231    number of changes, including fixes for several bugs that had gone
232    unnoticed until now:
233    
234      - uname "CYGWIN_NT*" is recognized as win32 (This is relevant only when
235        trying to run the win32 version from within cygwin.)
236    
237      - There are a number of simple .bat scripts that substitute for their
238        corresponding Unix shell-scripts.  (See below.)
239    
240      - The internals of ml-build have been modified slightly.  The main
241        difference is that instead of calling ".link-sml" (or link-sml.bat)
242        using OS.Process.system, the ML process delegates this task back
243        to the script.  Otherwise problems arise in mixed environments such
244        as Cygwin where scripts look and work like Unix scripts, but
245        where OS.Process.system cannot run them.
246    
247      - In CM, the srcpath pickler used native pathname syntax -- which
248        is incorrect in the case of cross-compilation.  The new pickle format
249        is independent of platform-specific naming conventions.
250    
251      - Path configuration files (such as lib/pathconfig) can now choose
252        between native and standard syntax.  Placing a line of the form
253    
254            standard!
255    
256        into the file causes all subsequent paths to be interpreted using
257        CM standard pathname syntax (= Unix conventions); a line
258    
259            native!
260    
261        switches back to native style.  This was needed so that
262        path config files can be written portably, see src/system/pathconfig.
263    
264      - Runtime system:
265    
266          - win32-filesys.c:  get_file_time and set_file_time now
267            access modification time, not creation time.
268    
269          - I/O code made aware of new array representation.
270    
271          - Bug fixes in X86.prim.masm.
272    
273       - src/system/makeml made aware of win32. (For use under cygwin
274            and other Unix-environments for windows.)
275    
276       - In Basis, fixed off-by-one error in win32-io.sml (function vecF)
277         which caused BinIO.inputAll to fail consistently.
278    
279    .bat scripts:
280    
281       Windows .bat scripts assume that SMLNJ_HOME is defined.
282    
283       - sml.bat, ml-yacc.bat, ml-lex.bat:  Driver scripts for standalone
284         applications (sml, ml-yacc, ml-lex).
285       - ml-build.bat: analogous to ml-build.
286       - config\install.bat:  Analogous to config/install.sh.  This requires
287         that SMLNJ_HOME is set and that Microsoft Visual C is ready to use.
288         (nmake etc. must be on the path, and vcvars32 must have been run.)
289         Moreover, sources for ml-lex and ml-yacc need to exist under src,
290         and the bootfile hierarchy must have been unpacked under
291         sml.boot.x86-win32.
292         The script is very primitive and does a poor job at error checking.
293         It only installs the base system, ml-lex, and ml-yacc.  No other
294         libraries are being installed (i.e., you get only those that
295         are part of the compiler.)
296       - link-sml.bat:  analogous to .link-sml, but not currently used
297    
298    Unrelated bug fixes:
299    
300      - ml-nlffigen now exports structures ST_* corresponding to incomplete
301        types.
302      - Added getDevice to PP/src/pp-debug-fn.sml.  (Would not compile
303        otherwise.)

327    Description:
328    
329    Two changes:
330    
331      1. Added a flag for controlling whether non-exhaustive bindings will
332         be treated as errors (default is false).
333      2. Cleaned up the *entire* source tree so that CMB.make goes through
334         without a single non-exhaustive match- or bind warning.

339    Tag: blume-20030517-absyn
340    Description:
341    
342    1. Added cases for IF, WHILE, ANDALSO, and ORELSE to Absyn.
343    
344       This mainly affects the quality of error messages.  However, some
345       of the code is now more straightforward than before. (Treatment of
346       the above four constructs in translate.sml is much simpler than
347       the "macro-expansion" that was going on before.  Plus, the mach-
348       compiler no longer gets invoked just to be able to compile an
349       if-expression.)
350    
351    2. The ErrorMsg.Error exception is now caught and absorbed by the
352       interactive loop.

358    Description:
359    
360        Ported the runtime system to cygwin, which uses the unix
361    x86-unix bin files.  Missing/buggy features:
362    
363       o getnetbyname, getnetbyaddr: these functions seem to be missing in
364         the Cygwin library.
365       o Ctrl-C handling may be flaky.
366       o Windows system calls and Windows I/O are not supported.
367    
368       A new set of binfiles is located at:
369    
370         http://www.dorsai.org/~leunga/boot.x86-unix.tgz
371    
372       This is only needed for bootstrapping the cygwin version of smlnj.
373       Other x86 versions can use the existing binfiles.

399    
400    Fixed a serious bug in the rewrite code for FP spilling/reloading that
401    sent the RA into an infinite loop when floating point registers get
402    spilled.  (Because of this bug, e.g., nucleic stopped compiling between
403    110.37 and 110.38.)
404    There was another set of potential problems related to the handling of
405    MLRISC annotations (but those did not yet cause real problems, apparently).

414    This fixes the problem of CM getting confused by files that suddenly
415    change their identity (e.g., by getting unlinked and recreated by some
416    text editor such as vi).  There might be a better/cheaper/cleaner way
417    of doing this, but for now this will have to do.

430    Tag: Release_110_42
431    Description:
432    
433    In good old tradition, there has been a slight hiccup so that we have
434    to patch 110.42 after the fact.   The old release tag has been replaced
435    (see below).
436    
437    The change solves a problem with two competing approaches the
438    configuration problem regarding MacOS 10.1 vs. MacOS 10.2 which got in
439    each other's way.
440    
441    This change only affects the runtime system code and the installer script.
442    (No new bootfiles.)

457    
458    The mltree operator DIVS must be implemented with an overflow check on

466    Description:
467    
468    Sml now senses the SMLNJ_HOME environment variable.  If this is set,
469    then the bin dir is assumed to be in $SMLNJ_HOME/bin and (unless
470    CM_PATHCONFIG is also set), the path configuration file is assumed
471    to be in $SMLNJ_HOME/lib/pathconfig.  This way one can easily move
472    the entire tree to some other place and everything will "just work".
473    
474    (Companion commands such as ml-build and ml-makedepend also sense this
475    variable.)

634    0. John Reppy made several modifications to the SML/NJ library.
635       In particular, there is a shiny new controls-lib.cm.
636    
637    1. Pushed new controls interface through compiler so that everything
638       compiles again.
639    
640    2. Added FormatComb and FORMAT_COMB to the CML version of the
641       SML/NJ library (so that CML compiles again).
642    
643    3. Modified init scripts because XXX_DEFAULT environment variables
644       are no longer with us.  (Boot-time initialization is now done
645       using the same environment variables that are also used for
646       startup-time initialization of controls.)

652    Description:
653    
654            All pseudo-ops emitted before the first segment declaration
655    such as TEXT, DATA, and BSS directives are assumed to be global
656    declarations and are emitted first in the assembly file. This is
657    useful in a number of situations where one has pseudo-ops that are not
658    specific to any segment, and also works around the constraint that one
659    cannot have client pseudo-ops in the TEXT segment.
660    
661            Because no segment is associated with these declarations it is
662    an error to allocate any space or objects before the first segment
663    directive and an exception will be raised. However, we cannot make
664    this check for client pseudo-ops.
665    
666            These top level declarations are a field in the CFG graph_info.
667    In theory you can continue to add to this field after the CFG has been
668    built -- provided you know what you are doing;-)

691    Description:
692    
693    Applied the following bugfix provided by Emden Gansner:
694    
695        Output is corrupted when outputSubstr is used rather than output.
696    
697        The problem occurs when a substring
698    
699            ss = (s, dataStart, dataLen)
700    
701        where dataStart > 0, fills a stream buffer with avail bytes left.
702        avail bytes of s, starting at index dataStart, are copied into the
703        buffer, the buffer is flushed, and then the remaining dataLen-avail
704        bytes of ss are copied into the beginning of the buffer. Instead of
705        starting this copy at index dataStart+avail in s, the current code
706        starts the copy at index avail.
707    
708        Fix:
709        In text-io-fn.sml, change line 695 from
710             val needsFlush = copyVec(v, avail, dataLen-avail, buf, 0)
711        to
712             val needsFlush = copyVec(v, dataStart+avail, dataLen-avail, buf, 0)

728    Description:
729    
730    Added full support for div/mod/rem/quot on the x86, using the machine
731    instruction's two results (without clumsily recomputing the remainder)
732    directly where appropriate.
733    
734    Some more extensive power-of-two support was added to the x86 instruction
735    selector (avoiding expensive divs, mods, and muls where they can be
736    replaced with cheaper shifts and masks).  However, this sort of thing
737    ought to be done earlier, e.g., within the CPS optimizer so that
738    all architectures benefit from it.
739    
740    The compiler compiles to a fixed point, but changes might be somewhat
741    fragile nevertheless.  Please, report any strange things that you might
742    see wrt. div/mod/quot/rem...

752    Fast paths (quotient > 0 or remainder = 0) are not affected, though.
753    The problem was with quotient = 0, because that alone does not tell

755    remainder and divisor have the same sign...  :(

764    
765    NEW BOOTFILES!!!    Version number bumped to 110.39.3.
766    
767    Primops have changed. This means that the bin/boot-file formats have
768    changed as well.
769    
770    To make sure that there is no confusion, I made a new version.
771    
772    
773    CHANGES:
774    
775    * removed REMT from mltree (remainder should never overflow).
776    
777    * added primops to deal with divisions of all flavors to the frontend
778    
779    * handled these primops all the way through so they map to their respective
780      MLRISC support
781    
782    * used these primops in the implementation of Int, Int32, Word, Word32
783    
784    * removed INLDIV, INLMOD, and INLREM as they are no longer necessary
785    
786    * parameterized INLMIN, INLMAX, and INLABS by a numkind
787    
788    * translate.sml now deals with all flavors of INL{MIN,MAX,ABS}, including
789      floating point
790    
791    * used INL{MIN,MAX,ABS} in the implementation of Int, Int32, Word, Word32,
792      and Real (but Real.abs maps to a separate floating-point-only primop)
793    
794    
795    TODO items:
796    
797    * Hacked Alpha32 instruction selection, disabling the selection of REMx
798      instructions because the machine instruction encoder cannot handle
799      them.  (Hppa, PPC, and Sparc instruction selection did not handle
800      REM in the first place, and REM is supported by the x86 machine coder.)
801    
802    * Handle DIV and MOD with DIV_TO_NEGINF directly in the x86 instruction
803      selection phase.  (The two can be streamlined because the hardware
804      delivers both quotient and remainder at the same time anyway.)
805    
806    * Think about what to do with "valOf(Int32.minInt) div ~1" and friends.
807      (Currently the behavior is inconsistent both across architectures and
808      wrt. the draft Basis spec.)
809    
810    * Word8 should eventually be handled natively, too.
811    
812    * There seems to be one serious bug in mltree-gen.sml.  It appears, though,
813      as if there currently is no execution path that could trigger it in
814      SML/NJ.  (The assumptions underlying functions arith and promotable do not
815      hold for things like multiplication and division.)

820    Tag: blume-20020327-mlrisc-divisions
821    Description:
822    
823    Added support for all four division operations (ML's div, mod, quot,
824    and rem) to MLRISC.  In the course of doing so, I also rationalized
825    the naming (no more annoying switch-around of DIV and QUOT), by
826    parameterizing the operation by div_rounding_mode (which can be either
827    DIV_TO_ZERO or DIV_TO_NEGINF).
828    
829    The generic MLTreeGen functor takes care of compiling all four
830    operations down to only round-to-zero div.
831    
832    Missing pieces:
833    
834      * Doing something smarter than relying on MLTreeGen on architectures
835        like, e.g., the x86 where hardware division delivers both quotient and
836        remainder at the same time.  With this, the implementation of the
837        round-to-neginf operations could be further streamlined.
838    
839      * Remove inlining support for div/mod/rem from the frontend and replace it
840        with primops that get carried through to the backend.  Do this for all
841        int and word types.

847    Description:
848    
849    I improved (hopefully without breaking them) the implementation of Int.div,
850    Int.mod, and Int.rem.   For this, the code in translate.sml now takes
851    advantage of the following observations:
852    
853      Let  q = x quot y      r = x rem y
854           d = x div  y      m = x mod y
855    
856    where "quot" is the round-to-zero version of integer division that
857    hardware usually provides.  Then we have:
858    
859         r = x - q * y        where neither the * nor the - will overflow
860         d = if q >= 0 orelse x = q * y then q else q - 1
861                              where neither the * nor the - will overflow
862         m = if q >= 0 orelse r = 0 then r else r + y
863                              where the + will not overflow
864    
865    This results in substantial simplification of the generated code.
866    The following table shows the number of CFG nodes and edges generated
867    for
868            fun f (x, y) = x OPER y
869            (* with OPER \in div, mod, quot, rem *)

945      3. RAW_CCALL/RCC now takes two extra arguments:
946    
947         a. The first is whether the C call is reentrant, i.e., whether
948            ML state should be saved and restored.
949         b. The second argument is a string argument specifying the name of
950            library and the C function.

958         even though "string" is also mapped into PTR, because "bool"
959         is assigned an CPS type of BOGt, while "string" is assigned INT32t.

982    Description:
983    
984    Implemented the Ball-Larus branch prediction-heuristics, and
985    incorporated graphical viewers for control flow graphs.
986    
987    Ball-Larus Heuristics:
988    ---------------------
989    See the file compiler/CodeGen/cpscompile/cpsBranchProb.sml.
990    
991    By design it uses the Dempster-Shafer theory for combining
992    probabilities.  For example, in the function:
993    
994        fun f(n,acc) = if n = 0 then acc else f(n-1, n*acc)
995    
996    the ball-larus heuristics predicts that the n=0 is unlikely
997    (OH-heuristic), and the 'then' branch is unlikely because of the
998    RH-heuristic -- giving the 'then' branch an even lower combined
999    probability using the Dempster-Shafer theory.
1000    
1001    Finally, John Reppy's loop analysis in MLRISC, further lowers the
1002    probability of the 'then' branch because of the loop in the else
1003    branch.
1004    
1005    
1006    Graphical Viewing:
1007    ------------------
1008    I merely plugged in Allen's graphical viewers into the compiler. The
1009    additional code is not much. At the top level, saying:
1010    
1011            Control.MLRISC.getFlag "cfg-graphical-view" := true;
1012    
1013    will display the graphical view of the control flow graph just before
1014    back-patching.  daVinci must be in your path for this to work. If
1015    daVinci is not available, then the default viewer can be changed
1016    using:
1017    
1018            Control.MLRISC.getString "viewer"
1019    
1020    which can be set to "dot" or "vcg" for the corresponding viewers. Of
1021    course, these viewers must be in your path.
1022    
1023    The above will display the compilation unit at the level of clusters,
1024    many of which are small, boring, and un-interesting. Also setting:
1025    
1026            Control.MLRISC.getInt "cfg-graphical-view_size"
1027    
1028    will display clusters that are larger than the value set by the above.

1051    Tag: leunga-20020321-x86-fp-cfg
1052    Description:
1053    
1054      1. Recoded the buggy parts of x86-fp.
1055    
1056         a. All the block reordering code has been removed.
1057            We now depend on the block placement phases to do this work.
1058    
1059         b. Critical edge splitting code has been simplified and moved into the
1060            CFG modules, as where they belong.
1061    
1062         Both of these were quite buggy and complex.  The code is now much, much
1063         simpler.
1064    
1065      2. X86 backend.
1066    
1067         a. Added instructions for 64-bit support.  Instruction selection for
1068            64-bit has not been committed, however, since that
1069            requires changes to MLTREE which haven't been approved by
1070            Lal and John.
1071    
1072         b. Added support for FUCOMI and FUCOMIP when generating code for
1073            PentiumPro and above.  We only generate these instructions in
1074            the fast-fp mode.
1075    
1076         c. Added cases for JP and JNP in X86FreqProps.
1077    
1078      3. CFG
1079    
1080         CFG now has a bunch of methods for edge splitting and merging.
1081    
1082      4. Machine description.
1083    
1084         John's simplification of MLTREE_BASIS.fcond broke a few machine
1085         description things:
1086    
1087         rtl-build.{sig,sml} and hppa.mdl fixed.
1088    
1089         NOTE: the machine description stuff in the repository is still broken.
1090               Again, I can't put my fixes in because that involves
1091               changes to MLTREE.

1109    Description:
1110    
1111    Added a structure C.W and functions convert/Ptr.convert to ml-nlffi-lib.
1112    
1113    This implements a generic mechanism for changing constness qualifiers
1114    anywhere within big C types without resorting to outright "casts".
1115    (So far, functions such as C.rw/C.ro or C.Ptr.rw/C.Ptr.ro only let you
1116    modify the constness at the outermost level.)
1117    The implementation of "convert" is based on the idea of "witness"
1118    values -- values that are not used by the operation but whose types
1119    "testify" to their applicability.  On the implementation side, "convert"
1120    is simply a projection (returning its second curried argument).  With
1121    cross-module inlining, it should not result in any machine code being
1122    generated.

1144    Description:
1145    
1146    Controls:
1147    ---------
1148    
1149    1. Factored out the recently-added Controls : CONTROLS stuff and put
1150       it into its own library $/controls-lib.cm.  The source tree for
1151       this is under src/smlnj-lib/Controls.
1152    
1153    2. Changed the names of types and functions in this interface, so they
1154       make a bit more "sense":
1155    
1156          module -> registry
1157          'a registry -> 'a group
1158    
1159    3. The interface now deals in ref cells only.  The getter/setter interface
1160       is (mostly) gone.
1161    
1162    4. Added a function that lets one register an already-existing ref cell.
1163    
1164    5. Made the corresponding modifications to the rest of the code so that
1165       everything compiles again.
1166    
1167    6. Changed the implementation of Controls.MLRISC back to something closer
1168       to the original.  In particular, this module (and therefore MLRISC)
1169       does not depend on Controls.  There now is some link-time code in
1170       int-sys.sml that registers the MLRISC controls with the Controls
1171       module.
1172    
1173    CM:
1174    ---
1175    
1176      * One can now specify the lambda-split aggressiveness in init.cmi.

1196    
1197    The problem was that the code generator did not generate any fp registers
1198    in this case, and the ra didn't know that it needed to run the X86FP phase to
1199    translate the pseudo fp instruction.   This only happened with unary fp
1200    operators in certain situations.

1229    Description:
1230    
1231    Yet another version number bump (because of small changes to the
1232    binfile format).  Version number is now 110.39.2.  NEW BOOTFILES!
1233    
1234    Changes:
1235    
1236      The new pid generation scheme described a few weeks ago was overly
1237      complicated.  I implemented a new mechanism that is simpler and
1238      provides a bit more "stability":  Once CM has seen a compilation
1239      unit, it keeps its identity constant (as long as you do not delete
1240      those crucial CM/GUID/* files).  This means that when you change
1241      an interface, compile, then go back to the old interface, and
1242      compile again, you arrive at the original pid.
1243    
1244      There now also is a mechanism that instructs CM to use the plain
1245      environment hash as a module's pid (effectively making its GUID
1246      the empty string).  For this, "noguid" must be specified as an
1247      option to the .sml file in question within its .cm file.
1248      This is most useful for code that is being generated by tools such
1249      as ml-nlffigen (because during development programmers tend to
1250      erase the tool's entire output directory tree including CM's cached
1251      GUIDs).  "noguid" is somewhat dangerous (since it can be used to locally
1252      revert to the old, broken behavior of SML/NJ, but in specific cases
1253      where there is no danger of interface confusion, its use is ok
1254      (I think).
1255    
1256      ml-nlffigen by default generates "noguid" annotations.  They can be
1257      turned off by specifying -guid in its command line.

1272    Description:
1273    
1274    Tested the jump chain elimination on all architectures (except the
1275    hppa).  This is on by default right now and is profitable for the
1276    alpha and x86, however, it may not be profitable for the sparc and ppc
1277    when compiling the compiler.
1278    
1279    The gc test will typically jump to a label at the end of the cluster,
1280    where there is another jump to an external cluster containing the actual
1281    code to invoke gc. This is to allow factoring of common gc invocation
1282    sequences. That is to say, we generate:
1283    
1284            f:
1285               testgc
1286               ja   L1      % jump if above to L1
1287    
1288            L1:
1289               jmp L2
1290    
1291    
1292    After jump chain elimination the 'ja L1' instructions is converted to
1293    'ja L2'. On the sparc and ppc, many of the 'ja L2' instructions may end
1294    up being implemented in their long form (if L2 is far away) using:
1295    
1296            jbe     L3      % jump if below or equal to L3
1297            jmp     L2
1298         L3:
1299            ...
1300    
1301    
1302    For large compilation units L2  may be far away.
