Revision 166382:

http://gcc.gnu.org/ml/gcc-cvs/2010-11/msg00269.html

failed to bootstrap on x86. I got

../../src-trunk/gcc/config/i386/i386.c: In function
'ix86_delegitimize_address':
../../src-trunk/gcc/config/i386/i386.c:13017:8: error: 'or' of unmatched
not-equal tests is always 1 [-Werror]
cc1: all warnings being treated as errors

make[6]: *** [i386.o] Error 1
make[6]: *** Waiting for unfinished jobs....

Code in question is

      if (GET_CODE (x) != CONST 
          || GET_CODE (XEXP (x, 0)) != UNSPEC
          || XINT (XEXP (x, 0), 1) != UNSPEC_GOTPCREL
          || XINT (XEXP (x, 0), 1) != UNSPEC_PCREL
          || !MEM_P (orig_x))
        return ix86_delegitimize_tls_address (orig_x);

It doesn't make any senses to me.
