| 1 : | anton | 1.2 | 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 : | |||
| 6 : | anton | 1.1 | 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). | ||
