Hi Everyone, For those still following this thread, to improve the reliability of this work some changes were made to glanForth(derived from AmForth). A hybrid of C generated and assembler code using asm(...) and C data structures is no longer being used, pure assembler generated code is being used instead, due to problems relating to the riscv toolchain used by MounRiver Studio (even the most up to date toolchain had these issues - still experimental???). The best results were obtained by using the pure riscv assembly code for amForth. Also to get consistent amforth dictionary alignment on 32 bit boundaries the NEXT macro wasn't being used with the primary words, instead a macro was used for each primary word along with a branch instruction to the next code in the ITC interpreter. These results were verified not by simulation but by actual hardware (chip level) observations. The latest build for a functioning riscv amforth (almost the complete code base) was 10,043 bytes for the CH32X033 and can function interactively or can co-exist with other C or assembler routines. An experimental version of the Expert System CLIPS V7 will be used to generate and verify forth code sequences with this build. Very little of the available SRAM has been used in this build, which can be used to store significant amounts of user forth programs.
