[Bug rtl-optimization/33846] [4.3 Regression] ICE in trunc_int_for_mode, at explow.c:55

------- Comment #4 from irar at il dot ibm dot com  2007-10-21 11:02 -------
The problem is with vector shift with scalar shift argument. 
For the code created by the vectorizer:
  vect_var_.49_103 = ~vect_var_.47_101;
  vect_var_.50_105 = vect_var_.49_103 >> 31;

(ashiftrt:V4SI (not:V4SI (reg:V4SI 100))
    (const_int 31 [0x1f]))
is created.

The failure is in
explow.c:55  gcc_assert (SCALAR_INT_MODE_P (mode)); 
since MODE is V4SImode.
