19    Description:
20    
21    Some bugs in install script fixed.
22    
23    In addition to that I also made a slight change to the NLFFI API:
24    Functors generated by ml-nlffigen now take the dynamic library as a
25    straight functor argument, not as a suspended one.  (The original
26    functor code used to force the suspension right away anyway, so there
27    was nothing gained by this complication of the interface.)

33    Description:
34    
35    I finally took the plunge and added my new FFI code to the main
36    repository.  For x86-linux it is now ready for prime-time.
37    
38    There are two new subdirectories of "src":
39    
40      - ml-nlffi-lib:
41           The utility library for programs using the FFI interface.
42           Here is the implementation of $/c.cm and its associated low-level
43           partners $/c-int.cm and $/memory.cm.
44      - ml-nlffigen:
45           A stand-alone program for generating ML glue code from C source
46           code.
47    
48    Building ml-nlffigen requires $/ckit-lib.cm.
49    
50    The config/install.sh script has been updates to do the Right Thing
51    (hopefully).
52    
53    Notice that the source tree for the C-Kit will not be put under "src"
54    but directly under the installation root directory.  (This is the
55    structure that currently exists on the CVS server when you check out
56    module "sml".)  Fortunately, config/install.sh knows about this oddity.
57    
58    Bugs: No documentation yet.

64    Description:
65    
66    Fixed a bug in the accounting code in cpsopt/contract.sml.  (The
67    wrapper/unwrapper elimination did not decrement usage counts and some
68    dead variables got overlooked by the dead-up logic.)

73    Tag: george-20010508-omit-frameptr
74    Description:
75    
76    Changes to implement the omit-frame-pointer optimization to support
77    raw C calls. For now, there is only support on the Intel x86, but
78    other architectures will follow as more experience is gained with this.

84    Tag: blume-20010507-proxies
85    Description:
86    
87    I made into "proxy libraries" all libraries that qualify for such a
88    change.  (A qualifying library is a library that has another library or
89    groups as its sole member and repeats that member's export list
90    verbatim.  A proxy library avoids this repetition by omitting its export
91    list, effectively inheriting the list that its (only) member exports.
92    See the CM manual for more explanation.)
93    The main effect is that explicit export lists for these libraries
94    do not have to be kepts in sync, making maintenance a bit easier.
95    
96    I also added copyright notices to many .cm-files.
97    
98    Last but not least, I made a new set of bootfiles.

103    Tag: blume-20010504-cm-lsplit
104    Description:
105    
106    0. John merged pending changes to $/smlnj-lib.cm
107    
108    1. Allen's previous change accidentally backed out of one of Lal's
109       earlier changes.  I undid this mistake (re-introducing Lal's change).
110    
111    2. I used the new topOrder' function from graph-scc.sml (from $/smlnj-lib.cm)
112       within the compiler where applicable.  There is some code simplification
113       because of that.
114    
115    3. The "split" phase (in FLINT) is now part of the default list of phases.
116       Compiler.Control.LambdaSplitting.* can be used to globally control the
117       lambda-splitting (cross-module-inlining) engine.  In addition to that,
118       it can now also be controlled on a per-source basis: CM has been taught
119       a new tool parameter applicable to ML source files.
120    
121       - To turn lambda-splitting off completely:
122            local open Compiler.Control.LambdaSplitting in
123                val _ = set Off
124            end
125       - To make "no lambda-splitting" the global default (but allow per-source
126         overriding); this is the initial setting:
127            local open Compiler.Control.LambdaSplitting in
128                val _ = set (Default NONE)
129            end
130       - To make "lambda-splitting with aggressiveness a" the global default
131         (and allow per-source overriding):
132            local open Compiler.Control.LambdaSplitting in
133                val _ = set (Default (SOME a))
134            end
135    
136       - To turn lambda-splitting off for a given ML souce file (say: a.sml)
137         write (in the respective .cm-file):
138            a.sml (lambdasplitting:off)
139       - To turn lambda-splitting for a.sml on with minimal aggressiveness:
140            a.sml (lambdasplitting:on)
141       - To turn lambda-splitting for a.sml on with aggressiveness <a> (where
142         <a> is a decimal non-negative integer):
143            a.sml (lambdasplitting:<a>)
144       - To turn lambda-splitting for a.sml on with maximal aggressiveness:
145            a.sml (lambdasplitting:infinity)
146       - To use the global default for a.sml:
147            a.sml (lambdasplitting:default)
148         or simply
149            a.sml

155    Description:
156    
157      MLRISC features.
158    
159      1. Fix to CMPXCHG instructions.
160      2. Changed RA interface to allow annotations in callbacks.
161      3. Added a new method to the stream interface to allow annotations updates.
