Test support, beside the slot packer: reads definitions in the notation DECOMPOSITION.md uses -- words, opcodes, literals, constants, labels, branches, FOR NEXT and FOR UNEXT, in-line macros, comments -- and lays them down through the slot packer, so they no longer have to be retyped opcode by opcode in C. Tested by assembling SWAP, UM/MOD, C@ and C! both ways on two nodes and comparing memory word for word, by running what is assembled, and on every error it reports, each with its line number.

# v4/
|
|
|
|
StarForth v4: the 32-instruction F18-derived core. The design lives in
|
|
`docs/v4.0.0/JUSTIFICATION.md` (why) and `docs/v4.0.0/DECOMPOSITION.md`
|
|
(every v3 word mapped to a v4 fate).
|
|
|
|
The first deliverable is the hosted C99 golden model (`JUSTIFICATION.md` §10,
|
|
step 1). It must pass POST and hold K≡1.0 with 32- and 64-bit cells on all
|
|
three host ISAs.
|
|
|
|
Acceptance (`JUSTIFICATION.md` §16): v4 must be equivalent to v3 at any point
|
|
in time, with the same vocabularies and behaviour, on the F18-derived engine;
|
|
and every ISA, hosted and bare metal, must still reach its `ok` prompt.
|
|
`make -C v4 test` passing is a development check, not acceptance.
|
|
|
|
What exists so far is the single node: registers, circular stacks, memory, all
|
|
32 opcodes, per-opcode and per-call-target heat, and three console
|
|
registers (`CONSOLE-TX`, which captures output, and `CONSOLE-RX` and `CONSOLE-STATUS`, which hand out
|
|
input a test feeds) standing in for the console node until the mesh exists. The tests load definitions
|
|
onto a node either opcode by opcode (`v4/include/v4/asm.h`) or as text in the notation `DECOMPOSITION.md`
|
|
uses (`v4/include/v4/text.h`). `make -C v4 test` builds
|
|
and runs the tests at both cell widths; `make -C v4 sanitize` repeats them
|
|
under ASan and UBSan. There is no compiler capsule, no POST and no K
|
|
measurement yet.
