added NEWS.vmgen

    1: User-visible changes between 0.5.9-20020901 and 0.6.0:
    2: 
    3: Support for upward-growing stacks (see "Stack growth direction" in the
    4:   manual)
    5: New macro in output: IMM_ARG.
    6: New input flag: include-skipped-insts (currently pointless).
    7: Lazy loading and eager storing of stack items in superinstructiuons;
    8:   this reduces register pressure (useful on 386), but causes compiler
    9:   warnings about unused variables.
   10: 
   11: 
   12: User-visible changes between 0.5.9-20020822 and 0.5.9-20020901:
   13: 
   14: The store optimization is now disabled by default, but can be enabled
   15: by the user.  Documentation for this optimization is also new.
   16: 
   17: 
   18: Use-visible changes between 0.5.9-20010501 and 0.5.9-20020822:
   19: 
   20: There is now a manual (in info, HTML, Postscript, or plain text format).
   21: 
   22: There is the vmgen-ex2 variant of the vmgen-ex example; the new
   23: variant uses a union type instead of lots of casting.
   24: 
   25: Both variants of the example can now be compiled with an ANSI C
   26: compiler (using switch dispatch and losing quite a bit of
   27: performance); tested with lcc.
   28: 
   29: There are several changes in the way you have to define macros (see
   30: node/section "Changes" in the manual).  I recommend keeping the
   31: gforth-0.5.9-20010501 version until you have completed the changes
   32: (note that you can have several versions of Gforth installed at the
   33: same time).
