Change the error message format for undefined symbols. Previously, undefined symbol errors are one line like this and wasn't easy to read. /ssd/clang/bin/ld.lld: error: /ssd/llvm-project/lld/ELF/Writer.cpp:207: undefined symbol 'lld::elf::EhFrameSection<llvm::object::ELFType<(llvm::support::endianness)0, true> >::addSection(lld::elf::InputSectionBase*)' This patch make it more structured like this. bin/ld.lld: error: undefined symbol: lld::elf::EhFrameSection<llvm::object::ELFType<(llvm::support::endianness)0, true> >>> Referenced by Writer.cpp:207 (/ssd/llvm-project/lld/ELF/Writer.cpp:207) >>> Writer.cpp.o in archive lib/liblldELF.a Discussion thread: http://lists.llvm.org/pipermail/llvm-dev/2017-March/111459.html Differential Revision: https://reviews.llvm.org/D31481 llvm-svn: 299097
