does not generate correct code for Windows

[szdytom]

I tired to port the compiler to Windws but there are some errors:

Generated out.s does not compile correctly on Windows.

GAS(the AT&T asm) on Windows don't work identical, it have a little difference about psedo-ops. So I wrote a cg.c for NASM.

It passes the compiling stage, but it still faces a runtime error.
It seems because of something called shadow storage on Windows:

The x64 Application Binary Interface (ABI) uses a four-register fast-call calling convention by default. Space is allocated on the call stack as a shadow store for callees to save those registers.

the x64 calling convention on Windows it very different (and hard to understand for me), do you have any idea on fixing this?

Is your nasm cg.c available @szdytom?
