Teresa Johnson	b80783587b	[ThinLTO] Rename COMDATs for COFF when promoting/renaming COMDAT leader ... Summary: COFF requires that COMDAT name match that of the leader. When we promote and rename an internal leader in ThinLTO due to an import, ensure we subsequently rename the associated COMDAT. Similar to D31963 which did this during ThinLTO module splitting. Fixes PR40414. Reviewers: pcc, inglorion Subscribers: mehdi_amini, dexonsmith, dmajor, llvm-commits Differential Revision: https://reviews.llvm.org/D57395 llvm-svn: 352763	2019-01-31 16:00:15 +00:00
