kcc updated this revision to Diff 106573.
kcc added a comment.

Use EmitObjAction; also link and initialize the targets so
that we actually call the optimizer.

2017-06-16 Thread Kostya Serebryany via Phabricator via cfe-commits 
kcc added a comment.

ignore this for now. I've found how to make it even more interesting (by using 
llvm::InitializeAllTargets, etc), will send an update later.
