...ollowing example, I have an auto generated hello world example optimized with -O3. The problem is, that the constant string is copied into a malloced mem area, then puts is called and then the memory is freed. There is also some leftover from the reference counters. These are found by the dead code eliminaton after the puts call. But before the puts call, the constant folded number is put into the memory and is never used. I was told that llvm assumes that a function also can read below the pointer, so dead code elimination does not work here. The second thing i would like to have there is to tell LLVM...
