Eli Friedman 81169f2e1b Fix for PR2607: SCEV miscomputing the loop count for loops with an ... SGT exit condition. Essentially, the correct way to flip an inequality in 2's complement is the not operator, not the negation operator. That said, the difference only affects cases involving INT_MIN. Also, enhance the pre-test search logic to be a bit smarter about inequalities flipped with a not operator, so it can eliminate the smax from the iteration count for simple loops. llvm-svn: 54184		2008-07-30 00:04:08 +00:00
