# Your compiler of choice: 'gcc' or 'clang', I dont judge.

# Whether to use the development cache for bootloader and firmware files.
# This downloads and stores any necessary UEFI firmware for testing and the limine
# bootloader in `.devel-cache`. Disable this if you want to use your own
# firmware and copy of limine.

# ---- Build System Options ----
# By default build commands are not echoed to stdout as there is a lot
# of information. Set this to 'no' if you are debugging the build system or 
# are interested in exactly what's being run.
QUIET_BUILD = yes
# Display the total count of TODOs within codebase after compile,

# slightly, and can be worth disabling on less powerful machines.

# Enable use of debugcon (port 0xE9) as a serial driver and early log output. 
# Only enable this for virtual machines.

# Whether to boot qemu with legacy bios instead of OVMF.

# ---- Motorola 680x0 Options ----
