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.

63    Tag: blume-20010509-cpscontract
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.

166    Tag: blume-20010501-pcedittmp
167    Description:
168    
169    Changed install.sh to use the current working directory instead of
170    /usr/tmp for a temporary file (pcedittmp).  The previous choice
171    of /usr/tmp caused trouble with MacOS X because of file premission
172    problems.

177    Tag: blume-20010420-inMLflag
178    Description:
179    
180     - added vp_limitPtrMask to vproc-state.h
181       (for use by the raw-C-calls mechanism to implement proper interrupt
182        handling)
183     - made the ML compiler aware of various data-structure offsets so it
184       can generate code for accessing the vp_inML flag and vp_limitPtrMask
185     - tweaked mlriscGen.sml to have it emit interrupt-handling code for
186       raw C-calls

192    Description:
193    
194     - Changes to port to Mac OS X; Darwin.
195    
196     - In the process I found that sqrt was broken on the PPC, because the
197       fsqrt instruction is not implemented.

202    Tag: blume-20010418-ccalls
203    Description:
204    
205     - fixed two off-by-4 errors in the x86-specific c-calls implementation
206       (this bug prevented structure arguments containing pointers from being
207        passed correctly)
208     - changed the raw-C-call code in mlriscGen.sml in such a way that
209       structure arguments are represented as a pointer to the beginning
210       of the structure (instead of having a series of synthesized arguments,
211       one for each structure member)
212    
213     - made makeml script's verbosity level configurable via environment
214       variable (MAKEML_VERBOSITY)
215    
216     - eliminated placeholder implementations for f32l, w16s, i16s, and f32s
217       in rawmem-x86.sml; we are now using the real thing

231    Description:
232    
233    1. All "raw memory access" primitives for the new FFI are implemented now
234       (at least on the x86).
235    2. Some further cleanup of CM's parallel make mechanism.
