In any case there will always be numerous limitations, but at least being able to perform the basic build check with limited options could save quite some time to many developers. Using gcc once the tcc-based "typo check" passes would already be a nice start. Getting the kernel to boot would indeed be a huge step forward! In haproxy we can only build with threading disabled and it works slowly but sufficiently for basic tests and printf- based debugging. It's convenient for bisecting certain bugs. Thanks for the video Boris, I wasn't aware of it, definitely interesting! Willy
