Annotation of gforth/NEWS.vmgen, revision 1.9

1.9     ! anton       1: User-visible changes between 0.6.2 and 0.7.0:
1.6       anton       2: 
1.9     ! anton       3: Bugfixes (in particular a Gforth bug when dealing with "../" is fixed).
1.4       anton       4: 
1.9     ! anton       5: Vmgen by default behaves just as in 0.6.2.  While some advances have
        !             6:   been implemented, the result is not mature enough for general
        !             7:   consumption and is therefore disabled by default.
1.4       anton       8: 
                      9: 
1.2       anton      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: 
1.1       anton      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).
