Subject: LoopGenerators: Expose some parts of the parallel loop generator
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=0bed1eab3937cc9c78baaef88ae85da9f3f91402;p=platform%2Fupstream%2Fllvm.git

LoopGenerators: Expose some parts of the parallel loop generator

Some of this functionality is useful beyond the generation of a normal OpenMP
loop.
