Subject: [Bug rtl-optimization/42246] ICE in init_seqno for 186.crafty with sel-sched
Date: Wed, 06 Jan 2010 18:48:00 -0000	[thread overview]
Message-ID: <20100106184836.27260.qmail@sourceware.org> (raw)

------- Comment #2 from janis at gcc dot gnu dot org  2010-01-06 18:48 -------
The patch at http://gcc.gnu.org/ml/gcc-patches/2009-12/msg01209.html fixes the
testcase in the submitter's description, but there is code in CPU2000 test
200.sixtrack that triggers the same ICE with the same set of options, as shown
by this minimized testcase:

      subroutine distance(x,clo)
      implicit real*8 (a-h,o-z)
      dimension x(2,6),x1(2,6),clo(6)
      do 60 i=1,2
        do 20 j=1,6
          x(i,j)=clo(j)
   20   continue
        do 40 iq=1,6
          x1(i,iq)=0.0d0
   40   continue
        do 50 j=1,6
          x(i,j)=x1(i,j)
   50   continue
   60 continue
      return
      end

This testcase gets the ICE with and without the patch cited above.
