    steps := 0
    while x != 1 {
        steps += 1
        if !(x % 2) {
            x /= 2
        }

Build

Only Linux builds are supported. Parts of the code are working on Windows, but it currently does not build with cl.exe. clang-cl might work.

The project should build with C++23-capable versions of clang and gcc, although clang is preferred. If both are installed, xmake will ask which one to use.

1. Download xmake (on Arch Linux, run sudo pacman -S xmake)
2. git clone https://github.com/lstrsrt/compiler
3. cd compiler
4. xmake

This builds in Release mode. To switch to a Debug build, run xmake config -m debug before xmake.

To run: ./build/{debug,release}/compiler [args...]. Pass --help for help.

The --exe flag and tests require nasm and gcc to be installed.
