*	Enable Loop Sink pass for functions that has profile.	Dehao Chen	2016-11-09	1	-0/+5
\| \| \| \| \| \| \| \| \| \| \| \|	Summary: For functions with profile data, we are confident that loop sink will be optimal in sinking code. Reviewers: davidxl, hfinkel Subscribers: mehdi_amini, mzolotukhin, llvm-commits Differential Revision: https://reviews.llvm.org/D26155 llvm-svn: 286325
*	Add Loop Sink pass to reverse the LICM based of basic block frequency.	Dehao Chen	2016-10-27	1	-0/+328
	Summary: LICM may hoist instructions to preheader speculatively. Before code generation, we need to sink down the hoisted instructions inside to loop if it's beneficial. This pass is a reverse of LICM: looking at instructions in preheader and sinks the instruction to basic blocks inside the loop body if basic block frequency is smaller than the preheader frequency.
