The fuzzer is very simple, but not quite useful at the moment: it's unable to discover "interesting" examples, as LLVMObject library is terrible at error recovery, calling "report_fatal_error()" far too often. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@238451 91177308-0d34-0410-b5e6-96231b3b80d8
