Re: [Tinycc-devel] tcc as compiler for tccboot

Hello Sergey, That's a good bit of sleuthing. A couple of questions immediately come to mind: - Why does gcc and pcc take 4 as their alignment? Why do we take 32? - Does this have any performance impact? - Is there a reason you are implementing this with #ifdef? Might we use a
