Author: yaxunl Date: Fri Nov 9 10:52:05 2018 New Revision: 346536 URL: http://llvm.org/viewvc/llvm-project?rev=346536&view=rev Log: [HIP] Remove useless sections in linked files
clang-offload-bundler creates __CLANG_OFFLOAD_BUNDLE__* sections in the bundles, which get into the linked files. These sections are useless after linking. They waste disk space and cause confusion for clang when directly linked with other object files, therefore should be removed.
