User-visible changes between 0.6.2 and 0.6.9 (up to 2006-05-07): variable THREADED-CODE-POINTER-TYPE for parameterizing Inst ** (undocumented) Better support for explicit stack access (see documentation) (works with static superinsts?) support for static multi-state stack caching (undocumented) User-visible changes between 0.6.[01] and 0.6.2: You now have to define a macro MAYBE_UNUSED (see manual); useful for suppressing expected "unused variable" warnings. User-visible changes between 0.5.9-20020901 and 0.6.0: Support for upward-growing stacks (see "Stack growth direction" in the manual) New macro in output: IMM_ARG. New input flag: include-skipped-insts (currently pointless). Lazy loading and eager storing of stack items in superinstructiuons; this reduces register pressure (useful on 386), but causes compiler warnings about unused variables. User-visible changes between 0.5.9-20020822 and 0.5.9-20020901: The store optimization is now disabled by default, but can be enabled by the user. Documentation for this optimization is also new. Use-visible changes between 0.5.9-20010501 and 0.5.9-20020822: There is now a manual (in info, HTML, Postscript, or plain text format). There is the vmgen-ex2 variant of the vmgen-ex example; the new variant uses a union type instead of lots of casting. Both variants of the example can now be compiled with an ANSI C compiler (using switch dispatch and losing quite a bit of performance); tested with lcc. There are several changes in the way you have to define macros (see node/section "Changes" in the manual). I recommend keeping the gforth-0.5.9-20010501 version until you have completed the changes (note that you can have several versions of Gforth installed at the same time). ----- Copyright (C) 2001, 2002, 2003,2006 Free Software Foundation, Inc.
