I have a set of two subtargets, each of them has a set of given features.

>From "llc" cmdline it is possible to enable/disable given feature on given
subtarget by adding: -attr=+/-<feature_name>

Is it possible to explicitly disable/enable a given feature from clang
I was trying to do it with "-mllvm -attr=feature_name", but it didn't work.
