qinzhao at gcc dot gnu.org changed: What |Removed |Added ---------------------------------------------------------------------------- Resolution|FIXED |--- Status|RESOLVED |REOPENED --- Comment #27 from qinzhao at gcc dot gnu.org --- since the call to MEM[(int[0:D.1993] *)&fb.3] = .DEFERRED_INIT (16, 2, 1); is NOT expanded at all during RTL expansion phase, The auto variable "int fb[tw]"; is not initialized to zero with this patch, which is not what we want. So, I think that we might need to reconsider the patch for this bug. I'm reopening this bug for a further discussion.
