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