Summary: This fixes an issue when files are compiled with -flto=thin at default -O0. We need to rename anonymous globals before attempting to write the module summary because all values need names for the summary. This was happening at -O1 and above, but not before the early exit when constructing the pipeline for -O0. Also add an internal -prepare-for-thinlto option to enable this to be tested via opt. Fixes PR30419. Reviewers: mehdi_amini Subscribers: probinson, llvm-commits, mehdi_amini Differential Revision: https://reviews.llvm.org/D24701 llvm-svn: 281840
