19    Description:
20    
21    1. Eliminated comp-lib.cm
22    2. Made pickle-lib.cm
23    3. Eliminated all uses of intset.sml (from comp-lib.cm)
24    4. Replaced all uses of intmap.{sig,sml} (from comp-lib.cm) with
25       equivalent constructs from smlnj-lib.cm (INtHashTable).
26    5. Point 4. also goes for those uses of intmap.* in MLRISC.
27       Duplicated intmap modules thrown out.
28    6. Hunted down all duplicated SCC code and replaced it with
29       equivalent stuff (GraphSCCFn from smlnj-lib.cm).
30    7. Rewrote Feedback module.
31    8. Moved sortedlist.sml into viscomp-lib.cm.  Eventually it
32       should be thrown out and equivalent modules from smlnj-lib.cm
33       should be used (IntRedBlackSet, IntListSet, ...).
34    
35    Confirmed that compiler compiles to fixpoint.

41    
42    A new x86 floating point code generator has been added.
43    By default this is turned off.  To turn this on, do:
44    
45        CM.autoload "$smlnj/compiler.cm";
46        Compiler.Control.MLRISC.getFlag "x86-fast-fp" := true;
47    
48    Changes:
49    
50    1.  Changed FTAN to FPTAN so that the assembly output is correct.
51    2.  Changed the extension callback for FTANGENT to generate:
52    
53              fptan
54              fstp  %st(0)
55        instead of
56              fptan
57              fstpl ftempmem
58    
59    3.  Numerous assembly fixes for x86.
60    
61    5.  Cleaned up the machine code output module x86/x86MC.sml and added
62        support for a whole bunch of instructions and addressing modes:
63    
64          fadd/fsub/fsubr/fmul/fdiv/fdivr  %st, %st(n)
65          faddp/fsubp/fsubrp/fmulp/fdivp/fdivrp  %st, %st(n)
66          fadd/fsub/fsubr/fmul/fdiv/fdivr  %st(n), %st
67          fiadd/fisub/fisubr/fimul/fidiv/fidivr mem
68          fxch %st(n)
69          fld %st(n)
70          fst %st(n)
71          fst mem
72          fstp %st(n)
73          fucom %st(n)
74          fucomp %st(n)
75    
76        All these are now generated when the fast fp mode is turned on.
77    
78    6.  Removed the dedicated registers %st(0), ..., %st(7) from X86CpsRegs

84    Description:
85    
86    Eliminated some code duplication:
87    
88    1. Added "where" clause to GraphSCCFn in SML/NJ Library.
89       (Otherwise the functor is useless.)
90    2. Used GraphSCCFn where SCCUtilFun was used previously.
91    3. Got rid of SCCUtilFun (in comp-lib.cm).
