Author: tejohnson Date: Tue Apr 19 21:23:52 2016 New Revision: 266852 URL: http://llvm.org/viewvc/llvm-project?rev=266852&view=rev Log: Enable ODR uniquing of DITypes for ThinLTO backends
Summary: This is a follow-on to apply Duncan's new DIType ODR uniquing from r266549 and r266713 in more places. When invoking ThinLTO backend compiles via clang (for a distributed build), invoke enableDebugTypeODRUniquing() before parsing the module.
