Daniil Fukalov fd35b81460 [SCEV] limit recursion depth and operands number in getAddExpr ... for a quite big function with source like %add = add nsw i32 %mul, %conv %mul1 = mul nsw i32 %add, %conv %add2 = add nsw i32 %mul1, %add %mul3 = mul nsw i32 %add2, %add ; repeat couple of thousands times that can be produced by loop unroll, getAddExpr() tries to recursively construct SCEV and runs almost infinite time. Added recursion depth restriction (with new parameter to set it) Reviewers: sanjoy Subscribers: hfinkel, llvm-commits, mzolotukhin Differential Revision: https://reviews.llvm.org/D28158 llvm-svn: 294181		2017-02-06 12:38:06 +00:00
