This is an assembler and VM written in Rust for the platform used in Eric Wastl (@topaz)'s lovely Synacor Challenge. The challenge describes the architecture of a fictional 16-bit mini-processor, and includes a binary containing the rest of the challenge.
Run cargo build. Binaries will drop in target/debug/.
For release mode (runs faster), run cargo build --release, which will drop binaries in target/release/.
Usage: synasm <input_source> --out <output_binary>.
Example program:
; Simplified fibonacci program
set $0 0 ; Init variables
set $1 1
out $0
out $1
loop:
add $2 $0 $1 ; Add
set $0 $1
set $1 $2 ; Shift
out $2 ; Print
jmp :loop ; Loop
The VM contains the assembler, so you can pass an asm file and it'll assemble as well as execute it. Or you can just pass the binary directly.
Usage: synvm <binary_file|--asm <asm_file>> [--input_str text] [--input_file file]
