Benjamin Kramer b49b964b98 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. llvm-svn: 127418		2011-03-10 18:40:14 +00:00
