In this change I have split the
/preForthdirectory into/commonand/i386and I have also split some of the Forth sources into bit-width depedent and/or direct/indirect threaded dependent files. So in the/commondirectory we now havehi16bit.forthhi32bit.forthseedForth16bit.preseedForth32bit.preand these are prefixed to the similarly named files
hi.forthandseedForth.preto set theminintandmaxintvalues, whereas in the/i386directory we now haveseedForth-i386.preseedForthRuntimei386.seedsourceand these are suffixed to
seedForth-i386-rts.preandseedForthRuntime.seedsourcerespectively to define some critical words implement the compiler ordoes>system, allowing us to insertcallinstructions for direct threaded and so forth.And then I have added the following new directories:
/asxv5pxxcontains a local copy of the GPLv3-licensed ASxxxx assemblers, (as a submodule that references my nick4 account on github), for bootstrapping. See https://shop-pdp.net/ashtml/asxxxx.php for the original source of these files./emu_z80contains a local copy of the MIT-licensed Z80 emulator at https://github.com/superzazu/z80 (as a submodule that references my nickd4 account on github), and a wrapper that t I developed to provide preForth-compatible I/O facilities./z80contains a copy of the/i386directory with appropriate changes:fasmi386 source changed toasz80source,Makefilechanged to buildbinfiles and run via the emulator, 32-bit changed to 16-bit, indirect threaded changed to direct.You can run
./seedand./seedForth-tokenizerin the/z80directory and they work pretty much the way they do in/i386.
