Annotation of gforth/NEWS.vmgen, revision 1.3
1.2 anton 1: User-visible changes between 0.6.[01] and 0.6.2:
2:
3: You now have to define a macro MAYBE_UNUSED (see manual); useful for
4: suppressing expected "unused variable" warnings.
5:
1.1 anton 6: User-visible changes between 0.5.9-20020901 and 0.6.0:
7:
8: Support for upward-growing stacks (see "Stack growth direction" in the
9: manual)
10: New macro in output: IMM_ARG.
11: New input flag: include-skipped-insts (currently pointless).
12: Lazy loading and eager storing of stack items in superinstructiuons;
13: this reduces register pressure (useful on 386), but causes compiler
14: warnings about unused variables.
15:
16:
17: User-visible changes between 0.5.9-20020822 and 0.5.9-20020901:
18:
19: The store optimization is now disabled by default, but can be enabled
20: by the user. Documentation for this optimization is also new.
21:
22:
23: Use-visible changes between 0.5.9-20010501 and 0.5.9-20020822:
24:
25: There is now a manual (in info, HTML, Postscript, or plain text format).
26:
27: There is the vmgen-ex2 variant of the vmgen-ex example; the new
28: variant uses a union type instead of lots of casting.
29:
30: Both variants of the example can now be compiled with an ANSI C
31: compiler (using switch dispatch and losing quite a bit of
32: performance); tested with lcc.
33:
34: There are several changes in the way you have to define macros (see
35: node/section "Changes" in the manual). I recommend keeping the
36: gforth-0.5.9-20010501 version until you have completed the changes
37: (note that you can have several versions of Gforth installed at the
38: same time).
