WebProtobufs provide a convenient way to serialize structured data, and LPM provides an easy way to mutate protobufs for structure-aware fuzzing. Thus, it is tempting to use libFuzzer+LPM for APIs that consume structured data other than protobufs. When fuzzing a data format Foo with LPM, these steps need to be made: Web☞ LLVM 7.0.1 LLVM中的Compiler-RT相当于GCC中的libgcc，为目标平台提供其硬件不支持的低级功能的优化实现。 Compiler-RT（RT指运行时）项目用于为硬件不支持的低级功能提供特定于目标的支持。例如，32位目标通常缺少支持64位除法的指令。Compiler-RT通过提供特定于目标并经过优化的功能来解决这个问题，该 ...
