llvm-mc tool hangs when -mcpu=help option is provided
jyoti.allur@jyotiallur-ubuntu:~/Downloads/clang+llvm-3.2-x86_64-linux-ubuntu-12.04/bin$
llvm-mc -mcpu=help
^Z
[5]+ Stopped llvm-mc -mcpu=help
This is same behaviour in trunk as well as some old versions like
llvm 3.4 & 3.2 versions.
Also if no files are provided to these tools, it should return an error
message, instead it hangs until ctrlC is used. This problem exists for llc as
well.
