    If you don't need __chkstk, you are not compiling for Windows
    and should
    not use a TinyCC that is targetting Windows. TinyCC targetting
    Linux does
    not emit calls to __chkstk.

If the official TinyCC developers were to make this one simple change, TinyCC would no longer be a no-go for me, and in fact TinyCC would then become my primary means to write Windows software.

It's quite puzzling to see this sort of request.

I agree with Austin that if the feature is so important, then consider patching it yourself. It is easier to compile tcc yourself and tweak whatever you want versus gcc. Or maybe use gcc -O0?

If you plan to write Windows software in C, I think assembly output doesn't really matter for most devs. For CPUs now cache misses are like train wrecks that limits max perf. Even how your executable is aligned when loaded may have big effects on performance. I just trust the compiler to do its thing. Install MinGW or MSYS2 and use gcc, apply whatever compiler options that are appropriate.

For modern PCs, I guess most devs still doing heavy-duty assembly are for math performance or multimedia performance. And x86_64 skills may be more important nowadays than x86 skills.

Even for embedded programming, there is usually zero need to think in assembly. Use the appropriate syntax and intrinsics and one can write C code quickly and productively without ever needing to remember CPU instruction mnemonics.

IMHO, to productively write Windows software in C, just think in C. I'm curious as to why you have this unusual need.
