21     - Changes to port to Mac OS X; Darwin.
22    
23     - In the process I found that sqrt was broken on the PPC, because the
24       fsqrt instruction is not implemented.

30    Description:
31    
32     - fixed two off-by-4 errors in the x86-specific c-calls implementation
33       (this bug prevented structure arguments containing pointers from being
34        passed correctly)
35     - changed the raw-C-call code in mlriscGen.sml in such a way that
36       structure arguments are represented as a pointer to the beginning
37       of the structure (instead of having a series of synthesized arguments,
38       one for each structure member)
39    
40     - made makeml script's verbosity level configurable via environment
41       variable (MAKEML_VERBOSITY)
42    
43     - eliminteded placeholder implementations for f32l, w16s, i16s, and f32s
44       in rawmem-x86.sml; we are now using the real thing

58    Description:
59    
60    1. All "raw memory access" primitives for the new FFI are implemented now
61       (at least on the x86).
62    2. Some further cleanup of CM's parallel make mechanism.

67    Tag: blume-20010319-parallel
68    Description:
69    
70    Parallel make (using compile servers) now works again.
71    
72    To this end, CM.stabilize and CMB.make have been modified to work in
73    two passes when compile servers are attached:
74       1. Compile everything, do not perform stabilization; this pass
75          uses compile servers
76       2. Stabilize everything; this pass does not use compile servers
77    If there are no compile servers, the two passes are combined into one
78    (as before).  Splitting the passes increases the inherent parallelism
79    in the dependency graph because the entire graph including all
80    libraries is available at the same time.  This, in turn, improves
81    server utilization.  The downside is that the master process will
82    have to do some extra work after compilation is done (because for
83    technical reasons it must re-read all the binfiles during stabilization).

105    Tag: leunga-20010305-cut-support
106    
107    1. New support for alternative control-flow in MLTREE.
108       Currently we support
109    
110          FLOW_TO(CALL ...., [k1,...,kn])
111    
112       This is needed for 'cuts to' in C-- and try/handle-like constructs
113       in Moby
114    
115       New assembler flag "asm-show-cutsto" to turn on control-flow debugging.
116    
117    2. Register Allocator
118    
119       Changes in interface [from Fermin, John]
120    
121    3. Alpha 8-bit SLL support [Fermin]
122    
123    4. All architectures
124    
125       A new module (ClusterExpandCopies) for expanding parallel copies.

140    Description:
141    
142    This is just a minor update to sync my devel branch with the main brach.
143    The only visible change is the addition of some README files.

151    Made a new set of bootfiles that goes with the current state of the
152    repository.

157    Tag: blume-20010112-sync
158    Description:
159    
160    I am just flushing out some minor changes that had accumulated in
161    my private branch in order to sync with the main tree.  (This is
162    mainly because I had CVS trouble when trying to merge _into_ my
163    private branch.)
164    
165    Most people should be completely unaffected by this.

170    Tag: leunga-20010111-labexp=mltree
171    Description:
172    
173    1.  Removed the type LabelExp and replace it by MLTree.
174    2.  Rewritten mltree-simplify with the pattern matcher tool.
175    3.  There were some bugs in alpha code generator which would break
176        64-bit code generation.
177    4.  Redo the tools to generate code with the
178    5.  The CM files in MLRISC (and in src/system/smlnj/MLRISC)
179        are now generated by perl scripts.
