Subject: When printing types for the OpenCL kernel metadata, use the PrintingPolicy.
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=92a47442f4a362fd634353316d632a1ef87ea106;p=platform%2Fupstream%2Fllvm.git

When printing types for the OpenCL kernel metadata, use the PrintingPolicy.

This allows 'half' to be printed as 'half' and not as '__fp16'.

Patch by Fraser Cormack!
