Intel 8086 instruction decoder and emulator written as an exercise to learn Zig. Given a binary input file representing Intel 8086 instructions, will output the decoded assembly instructions. Can optionally also emulate running instructions and inspect register and flag state.
Encodings based on the information in Intel 8086 Family User's Manual.
To build:
zig build
To run:
./decoder FILENAME [execute]
The optional parameter execute will emulate running the input file.
