This project has been retired. Albert van der Horst contributed a much more complete and powerful assembler to RetroForth, so we no longer see a need to write yet another one.
| Retrospect Mini-Assembler | ------------------------------------------------------------ | This isn't a full x86 assembler; it just supports some | basic instructions and such used in Retrospect. | ------------------------------------------------------------ | When possible, we use a form of: | <source> <dest> instruction | ------------------------------------------------------------ : eax 0 ; : ecx 1 ; : edx 2 ; : ebx 3 ; : esp 4 ; : ebp 5 ; : esi 6 ; : edi 7 ; | ------------------------------------------------------------ : push-r $50 + 1, ; : pop-r $58 + 1, ; : mov-ir $b8 + 1, , ; : mov-rr swap push-r pop-r ; | ------------------------------------------------------------ : label create: ; | Create a label : opcode create: literal, ['] 1, compile exit, ; : opcodes: for wsparse >number opcode next ; 2 opcodes: $c3 ret $ad lodsd | ------------------------------------------------------------ | This is a test program: label a 100 edx mov-ir edx eax mov-rr ret 200 a
This replaces the older one I was working on with a much cleaner codebase for the same level of functionality. The syntax takes a bit of getting used to, but it's nice to work with once you understand it.
