¶llvm::Error collectPGOFuncNameStrings(
    ArrayRef<std::string> NameStrs,
    bool doCompression,
    std::string& Result)

Description

Given a vector of strings (function PGO names) \c NameStrs, the method generates a combined string \c Result that is ready to be serialized. The \c Result string is comprised of three fields: The first field is the length of the uncompressed strings, and the the second field is the length of the zlib-compressed string. Both fields are encoded in ULEB128. If \c doCompress is false, the third field is the uncompressed strings; otherwise it is the compressed string. When the string compression is off, the second field will have value zero.
