Subject: FlattenAlgo: Ensure we _really_ obtain a param space
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=5aea5653b39bb54c675a8b6729171f2069ed4238;p=platform%2Fupstream%2Fllvm.git

FlattenAlgo: Ensure we _really_ obtain a param space

This resolves "isl_space.c:1775: not a parameter space" errors I have seen
on two systems.
