[Remarks] Silence gcc warning by catching unhandled values in switches Without this fix gcc (7.4) complains with ../lib/Remarks/RemarkParser.cpp: In function 'std::unique_ptr<llvm::remarks::ParserImpl> formatToParserImpl(llvm::remarks::ParserFormat, llvm::StringRef)': ../lib/Remarks/RemarkParser.cpp:29:1: error: control reaches end of non-void function [-Werror=return-type] } ^ ../lib/Remarks/RemarkParser.cpp: In function 'std::unique_ptr<llvm::remarks::ParserImpl> formatToParserImpl(llvm::remarks::ParserFormat, llvm::StringRef, const llvm::remarks::ParsedStringTable&)': ../lib/Remarks/RemarkParser.cpp:38:1: error: control reaches end of non-void function [-Werror=return-type] } ^ The Format enum currently only contains the value YAML which is indeed already handled in the switches, but gcc complains anyway. Adding a default case with an llvm_unreachable silences gcc. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@365118 91177308-0d34-0410-b5e6-96231b3b80d8 Mikael Holmen a month ago
