Updated NEWS.vmgen (incomplete?) and NEWS

    1: Disabled vmgen installation for now
    2: 
    3: User-visible changes between 0.6.2 and 0.6.9 (up to 2006-05-07):
    4: 
    5: variable THREADED-CODE-POINTER-TYPE for parameterizing Inst ** (undocumented)
    6: Better support for explicit stack access (see documentation) (works with static superinsts?)
    7: support for static multi-state stack caching (undocumented)
    8: 
    9: 
   10: User-visible changes between 0.6.[01] and 0.6.2:
   11: 
   12: You now have to define a macro MAYBE_UNUSED (see manual); useful for
   13:   suppressing expected "unused variable" warnings.
   14: 
   15: User-visible changes between 0.5.9-20020901 and 0.6.0:
   16: 
   17: Support for upward-growing stacks (see "Stack growth direction" in the
   18:   manual)
   19: New macro in output: IMM_ARG.
   20: New input flag: include-skipped-insts (currently pointless).
   21: Lazy loading and eager storing of stack items in superinstructiuons;
   22:   this reduces register pressure (useful on 386), but causes compiler
   23:   warnings about unused variables.
   24: 
   25: 
   26: User-visible changes between 0.5.9-20020822 and 0.5.9-20020901:
   27: 
   28: The store optimization is now disabled by default, but can be enabled
   29: by the user.  Documentation for this optimization is also new.
   30: 
   31: 
   32: Use-visible changes between 0.5.9-20010501 and 0.5.9-20020822:
   33: 
   34: There is now a manual (in info, HTML, Postscript, or plain text format).
   35: 
   36: There is the vmgen-ex2 variant of the vmgen-ex example; the new
   37: variant uses a union type instead of lots of casting.
   38: 
   39: Both variants of the example can now be compiled with an ANSI C
   40: compiler (using switch dispatch and losing quite a bit of
   41: performance); tested with lcc.
   42: 
   43: There are several changes in the way you have to define macros (see
   44: node/section "Changes" in the manual).  I recommend keeping the
   45: gforth-0.5.9-20010501 version until you have completed the changes
   46: (note that you can have several versions of Gforth installed at the
   47: same time).
