[Bug bootstrap/42369] [4.5 Regression] Revision 155217 failed to bootstrap

------- Comment #1 from hjl dot tools at gmail dot com  2009-12-14 19:01 -------
It is caused by revision 155217:

http://gcc.gnu.org/ml/gcc-cvs/2009-12/msg00361.html

The problem is

;; Single word integer modes without QImode and HImode.
(define_mode_iterator SWI48 [SI (DI "TARGET_64BIT")])

with

             case CODE_FOR_lwp_lwpvalsi3:
             case CODE_FOR_lwp_lwpvaldi3:
             case CODE_FOR_lwp_lwpinssi3:
             case CODE_FOR_lwp_lwpinsdi3:


Both CODE_FOR_lwp_lwpvaldi3 and CODE_FOR_lwp_lwpinsdi3
are  CODE_FOR_nothing for ia32.

I don't think you can use (DI "TARGET_64BIT") in define_mode_iterator.
