Annotation of gforth/NEWS.vmgen, revision 1.4
1.4 ! anton 1: User-visible changes between 0.6.2 and 0.6.9 (up to 2006-05-07):
! 2:
! 3: variable THREADED-CODE-POINTER-TYPE for parameterizing Inst ** (undocumented)
! 4: Better support for explicit stack access (see documentation) (works with static superinsts?)
! 5: support for static multi-state stack caching (undocumented)
! 6:
! 7:
1.2 anton 8: User-visible changes between 0.6.[01] and 0.6.2:
9:
10: You now have to define a macro MAYBE_UNUSED (see manual); useful for
11: suppressing expected "unused variable" warnings.
12:
1.1 anton 13: User-visible changes between 0.5.9-20020901 and 0.6.0:
14:
15: Support for upward-growing stacks (see "Stack growth direction" in the
16: manual)
17: New macro in output: IMM_ARG.
18: New input flag: include-skipped-insts (currently pointless).
19: Lazy loading and eager storing of stack items in superinstructiuons;
20: this reduces register pressure (useful on 386), but causes compiler
21: warnings about unused variables.
22:
23:
24: User-visible changes between 0.5.9-20020822 and 0.5.9-20020901:
25:
26: The store optimization is now disabled by default, but can be enabled
27: by the user. Documentation for this optimization is also new.
28:
29:
30: Use-visible changes between 0.5.9-20010501 and 0.5.9-20020822:
31:
32: There is now a manual (in info, HTML, Postscript, or plain text format).
33:
34: There is the vmgen-ex2 variant of the vmgen-ex example; the new
35: variant uses a union type instead of lots of casting.
36:
37: Both variants of the example can now be compiled with an ANSI C
38: compiler (using switch dispatch and losing quite a bit of
39: performance); tested with lcc.
40:
41: There are several changes in the way you have to define macros (see
42: node/section "Changes" in the manual). I recommend keeping the
43: gforth-0.5.9-20010501 version until you have completed the changes
44: (note that you can have several versions of Gforth installed at the
45: same time).
