Rekai Nyangadzayi Musuka e29c20019d fix: advance r15, even when the pipeline is reloaded from the scheduler The PC would fall behind whenever an IRQ was called because the pipeline was reloaded (+8 to PC), however that was never actually done by any code Now, the PC is always incremented when the pipeline is reloaded		2022-10-21 05:13:07 -03:00

Most recently built on Zig 0.10.0-dev.3900+ab4b26d8a

bitfields.zig from FlorenceOS is included under lib/util/bitfield.zig.

Use git submodule update --init from the project root to pull the git submodules SDL.zig, zig-clap, and known-folders

Be sure to provide SDL2 using:

SDL.zig will provide a helpful compile error if the zig compiler is unable to find SDL2.

Once you've got all the dependencies, execute zig build -Drelease-fast. The executable is located at zig-out/bin/.
