Nick Lewycky	8d2e86db5a	Fix an oversight in isPotentiallyReachable where we wouldn't do any CFG-walking to find loops if the From and To instructions were in the same block. Refactor the code a little now that we need to fill to start the CFG-walking algorithm with more than one starting basic block sometimes. Special thanks to Andrew Trick for catching an error in my understanding of natural loops in code review. llvm-svn: 188236	2013-08-13 00:03:47 +00:00
Nick Lewycky	0b68245ec8	Reimplement isPotentiallyReachable to make nocapture deduction much stronger. Adds unit tests for it too. Split BasicBlockUtils into an analysis-half and a transforms-half, and put the analysis bits into a new Analysis/CFG.{h,cpp}. Promote isPotentiallyReachable into llvm::isPotentiallyReachable and move it into Analysis/CFG. llvm-svn: 187283	2013-07-27 01:24:00 +00:00

Fix an oversight in isPotentiallyReachable where we wouldn't do any CFG-walking

to find loops if the From and To instructions were in the same block.

Refactor the code a little now that we need to fill to start the CFG-walking
algorithm with more than one starting basic block sometimes.

Special thanks to Andrew Trick for catching an error in my understanding of
natural loops in code review.

Split BasicBlockUtils into an analysis-half and a transforms-half, and put the
analysis bits into a new Analysis/CFG.{h,cpp}. Promote isPotentiallyReachable
into llvm::isPotentiallyReachable and move it into Analysis/CFG.
