20    This update just merges three minor cosmetic updates to CM's sources
21    to get ready for the 110.27 code freeze on Friday.  No functionality
22    has changed.

28    Description:
29    
30    1.  Fixed a problem in X86 assembly.
31    
32        Things like
33    
34           jmp %eax
35           jmp (%eax)
36    
37        should be output as
38    
39           jmp *%eax
40           jmp *(%eax)
41    
42    2.  Assembly output
43    
44          Added a new flag
45    
46              "asm-indent-copies" (default to false)
47    
48          When this flag is on, parallel copies will be indented an extra level.

53    Tag: leunga-20000404-C--Moby
54    Description:
55    
56        All of these fixes are related to C--, Moby, and my own optimization
57        stuff; so they shouldn't affect SML/NJ.
58    
59    1.  X86
60    
61        Various fixes related floating point, and extensions.
62    
63    2.  Alpha
64    
65        Some extra patterns related to loads with signed/zero extension
66        provided by Fermin.
67    
68    3.  Assembly
69    
70        When generating assemby, resolve the value of client defined constants,
71        instead of generating symbolic values.  This is controlled by the
72        new flag "asm-resolve-constants", which is default to true.
73    
74    4.  Machine Descriptions
75    
76        a. The precedence parser was slightly broken when parsing infixr symbols.
77        b. The type generalizing code had the bound variables reversed, resulting
78           in a problem during arity raising.
79        c. Various fixes in machine descriptions.

85    Description:
86    
87    I eliminated coreEnv from compInfo.  Access to the "Core" structure is
88    now done via the ordinary static environment that is context to each
89    compilation unit.
90    
91    To this end, I arranged that instead of "structure Core" as "structure
92    _Core" is bound in the pervasive environment.  Core access is done via
93    _Core (which can never be accidentially rebound because _Core is not a
94    legal surface-syntax symbol).
95    
96    The current solution is much cleaner because the core environment is
97    now simply part of the pervasive environment which is part of every
98    compilation unit's context anyway.  In particular, this eliminates all
99    special-case handling that was necessary until now in order to deal
100    with dynamic and symbolic parts of the core environment.
101    
102    Remaining hackery (to bind the "magic" symbol _Core) is localized in the
103    compilation mananger's bootstrap compiler (actually: in the "init group"
104    handling).  See the comments in src/system/smlnj/init/init.cmi for
105    more details.
106    
107    I also tried to track down all mentions of "Core" (as string argument
108    to Symbol.strSymbol) in the compiler and replaced them with a
109    reference to the new CoreSym.coreSym.  Seems cleaner since the actual
110    name appears in one place only.
111    
112    Binfile and bootfile format have not changed, but the switchover from
113    the old "init.cmi" to the new one is a bit tricky, so I supplied new
114    bootfiles anyway.

120    Description:
121    
122       1. Renamed the constructor CALL in MLTREE by popular demand.
123       2. Added a bunch of files from my repository.  These are currently
124          used by other non-SMLNJ backends.
