By kripken:

The dlmalloc and optimize options are still relevant when the input is from stdin, I think. These options are things done on the LLVM assembly we are going to compile, it doesn't matter if it is from a file or from stdin.

(If it helps, I am fine with assuming that input from stdin is textual .ll and not binary .bc content)
