David Majnemer 594e4a1dd3 InstSimplify: Simplify trivial pointer expressions like b + (e - b) ... consider: long long *f(long long *b, long long *e) { return b + (e - b); } we would lower this to something like: define i64* @f(i64* %b, i64* %e) { %1 = ptrtoint i64* %e to i64 %2 = ptrtoint i64* %b to i64 %3 = sub i64 %1, %2 %4 = ashr exact i64 %3, 3 %5 = getelementptr inbounds i64* %b, i64 %4 ret i64* %5 } This should fold away to just 'e'. N.B. This adds m_SpecificInt as a convenient way to match against a particular 64-bit integer when using LLVM's match interface. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@216439 91177308-0d34-0410-b5e6-96231b3b80d8		2014-08-26 05:55:16 +00:00
