RE: [Tinycc-devel] jmp_buf align problem on win64

[Christian Jullien]

I'm using headers from tcc.
Thanks for your suggestion, I'm not trying to fix my code which is already
fixed (easy) I'm trying to contribute to improve tcc by fixing the problem
itself.

I spent around 4h tonight to test different things. None work yet.
Of course, I want the fix be in tcc and/or JUM_BUF declaration not in any
user's code.

C.

are you using GNU headers? i remember that something in it #defines
__attribute__ to noop for me sometimes. somehow this code:

int main () {
  __attribute__((aligned(8))) char c0;
  __attribute__((aligned(8))) char c1;
  return 0;
}

works, and this:

#include <setjmp.h>
int main () {
  __attribute__((aligned(8))) char c0;
  __attribute__((aligned(8))) char c1;
  return 0;
}

turns "__attribute__((aligned(8)))" into nothing (as -E says).
and if i write "#undef __attribute__" after including, it works again.

dont know if this is my particular problem or so (can't check on
win-x64 for now).
