[PATCH] D51313: [LV] Fix code gen for conditionally executed uniform loads

[Anna Thomas via Phabricator via llvm-commits]

anna updated this revision to Diff 163148.
anna added a comment.

addressed review comments - we make sure that the vectorization also uses the cost decision of gather/scatter
instead of scalarizing.
Also, handles the original bug of generating incorrect code for conditional uniform loads.
