21    Some hacking to make autoloading faster.  Success for CMB, no success
22    so far for CM.  There is a reduced structure CM' that autoloads faster.
23    (This is a temporary, non-documented hack to be eliminated again when
24    the general problem is solved.)

30    Description:
31    
32    1. Eliminated comp-lib.cm
33    2. Made pickle-lib.cm
34    3. Eliminated all uses of intset.sml (from comp-lib.cm)
35    4. Replaced all uses of intmap.{sig,sml} (from comp-lib.cm) with
36       equivalent constructs from smlnj-lib.cm (INtHashTable).
37    5. Point 4. also goes for those uses of intmap.* in MLRISC.
38       Duplicated intmap modules thrown out.
39    6. Hunted down all duplicated SCC code and replaced it with
40       equivalent stuff (GraphSCCFn from smlnj-lib.cm).
41    7. Rewrote Feedback module.
42    8. Moved sortedlist.sml into viscomp-lib.cm.  Eventually it
43       should be thrown out and equivalent modules from smlnj-lib.cm
44       should be used (IntRedBlackSet, IntListSet, ...).
45    
46    Confirmed that compiler compiles to fixpoint.

52    
53    A new x86 floating point code generator has been added.
54    By default this is turned off.  To turn this on, do:
55    
56        CM.autoload "$smlnj/compiler.cm";
57        Compiler.Control.MLRISC.getFlag "x86-fast-fp" := true;
58    
59    Changes:
60    
61    1.  Changed FTAN to FPTAN so that the assembly output is correct.
62    2.  Changed the extension callback for FTANGENT to generate:
63    
64              fptan
65              fstp  %st(0)
66        instead of
67              fptan
68              fstpl ftempmem
69    
70    3.  Numerous assembly fixes for x86.
71    
72    5.  Cleaned up the machine code output module x86/x86MC.sml and added
73        support for a whole bunch of instructions and addressing modes:
74    
75          fadd/fsub/fsubr/fmul/fdiv/fdivr  %st, %st(n)
76          faddp/fsubp/fsubrp/fmulp/fdivp/fdivrp  %st, %st(n)
77          fadd/fsub/fsubr/fmul/fdiv/fdivr  %st(n), %st
78          fiadd/fisub/fisubr/fimul/fidiv/fidivr mem
79          fxch %st(n)
80          fld %st(n)
81          fst %st(n)
82          fst mem
83          fstp %st(n)
84          fucom %st(n)
85          fucomp %st(n)
86    
87        All these are now generated when the fast fp mode is turned on.
88    
89    6.  Removed the dedicated registers %st(0), ..., %st(7) from X86CpsRegs
