Functional Intel 8080 emulator written in Rust
The project is tested with a number of 8080 test binaries that I could find online.
The compare_i8080 tests run the test binaries side-by-side to mohanson/i8080 and compare the CPU state,
and fail if the CPU states do not match. These by default do not show the last instruction that caused the inconsistency due to the performance hit
this creates with the current implementation, but it can be opted in using the keep_old_state flag, and the ignored
compare_on_8080exm_print_failed_instruction already uses this.
The diag_suites test simply run the test binaries, so they can't really fail properly since there is no clear indicator besides the console output.
Run them with -- --nocapture to see console outputs to see the binary's output, and if running multiple tests, use --test-threads=1 to run
only 1 at a time so console outputs don't conflict.
Run tests in release since the larger test binaries take a very long time without optimizations!
Run all tests:
cargo test --release
Run diag binaries:
cargo test --release --test diag_suites -- --nocapture --test-threads=1
Run the largest test suite with failed instruction report (very slow):
cargo test --release -- compare_on_8080exm_print_failed_instruction --ignored
