Subject: [Bug tree-optimization/13745] [tree-ssa] expressions not converted back to array form
Date: Tue, 20 Sep 2005 17:17:00 -0000	[thread overview]
Message-ID: <20050920171645.6318.qmail@sourceware.org> (raw)
In-Reply-To: <20040119185038.13745.dann@godzilla.ics.uci.edu>


------- Additional Comments From pinskia at gcc dot gnu dot org  2005-09-20 17:16 -------
The difference now is:
<L2>:;
  sum = MEM[base: (int *) ivtmp.278] * MEM[base: (int *) ivtmp.280] + sum;
  k = k + 1;
  ivtmp.278 = ivtmp.278 + 4B;
  ivtmp.280 = ivtmp.280 + 200B;
  if (k != 50) goto <L2>; else goto <L4>;

For c_style.

And
<L2>:;
  sum = sum + C[(unsigned int) (int) ((unsigned int) k + ivtmp.1004)] * D[(unsigned int) (int) ivtmp.991];
  k = k + 1;
  ivtmp.991 = ivtmp.991 + 50;
  if (k != 50) goto <L2>; else goto <L4>;

For oop_style which means we don't do IV-opts on it for some reason.
