Benjamin Kramer 6b96fe7e14 InstCombine: Turn umul_with_overflow into mul nuw if we can prove that it cannot overflow. ... This happens a lot in clang-compiled C++ code because it adds overflow checks to operator new[]: unsigned *foo(unsigned n) { return new unsigned[n]; } We can optimize away the overflow check on 64 bit targets because (uint64_t)n*4 cannot overflow. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@127418 91177308-0d34-0410-b5e6-96231b3b80d8		2011-03-10 18:40:14 +00:00
