[Bug target/34584] New: alignment on .comm symbol ignored

[pinskia at gcc dot gnu dot org]

A simple testcase to check if the attribute aligned works, fails on
i386-darwin-apple:
#include <stdio.h>
#include <stdlib.h>
int array[4128] __attribute__((aligned( 2<<6)));
int main(void)
{

  __SIZE_TYPE__ a = (__SIZE_TYPE__)(&array[0]);
  printf("%d\n", (int)(__SIZE_TYPE__)a & ((2<<6) - 1));
  if((__SIZE_TYPE__)(a) &((2<<6) - 1))
   abort ();
  return 0;
}

---- CUT ----
Note I used a seperate variable for the address to work around the fact the
trunk can fold out the alignment check.
