 The regression appeared with this patch:
 
 Sat Mar 30 14:08:55 CET 2002  Jan Hubicka  <jh at suse dot cz>
 
         * i386.c (aligned_operand): Be prepared for SUBREGed registers.
         (ix86_decompose_address): Use REG_P instead of GET_CODE (...) ==
 REG.
         (ix86_address_cost): Be prepared for SUBREGed registers.
         (legitimate_address_p): Accept SUBREGed registers.
 
 The hunt used -O with Wolfgang's minimized testcase on
 i686-pc-linux-gnu.  This change was checked in at the same
 time as four others that appear to be unrelated to each
 other, and I verified that this one breaks the test case.
