remove reusing argument on stack

#39 .

only tested on linux. so this needs test on OSX and Windows.

BTW, for OSX the JIT is disabled because the ABI requires 4 or 8 words alignement

I started working on it years ago (see the STACK_ALIGN clause) but didn't complete it. Tell me if you're interested contributing to it (either as open source contribution or paid by Haxe Foundation).

Thanks!
but I can't help about OSX issue. because I'm not Apple user.

4 words(16bytes) alignment!? ...wow:open_mouth:

[ncannasse]

We could make a debug mode that check Esp % 16 before calling any C function if that works for you

Ah, feel like I can do it. but I can't promise :)

Before that, can I PullRequest few small change?

• improve Makefile: add .o .c .h dependency. rebuild require make -B for now.
  • dependency tracking, that is GNU-Make made for.
• add tests/ directory: test code here, and make test for test easily.

I start reading this. hmmm...

Sure
