Andrew Trick 53b28f8623 indvars: Improve LFTR by eliminating truncation when comparing against a constant. ... Patch by Michele Scandale! Adds a special handling of the case where, during the loop exit condition rewriting, the exit value is a constant of bitwidth lower than the type of the induction variable: instead of introducing a trunc operation in order to match correctly the operand types, it allows to convert the constant value to an equivalent constant, depending on the initial value of the induction variable and the trip count, in order have an equivalent comparison between the induction variable and the new constant. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@186107 91177308-0d34-0410-b5e6-96231b3b80d8		2013-07-11 17:08:59 +00:00
