This is straightforward mapping of PR_LOG levels to their LogLevel counterparts: PR_LOG_ERROR -> LogLevel::Error PR_LOG_WARNING -> LogLevel::Warning PR_LOG_WARN -> LogLevel::Warning PR_LOG_INFO -> LogLevel::Info PR_LOG_DEBUG -> LogLevel::Debug PR_LOG_NOTICE -> LogLevel::Debug PR_LOG_VERBOSE -> LogLevel::Verbose Instances of PRLogModuleLevel were mapped to a fully qualified mozilla::LogLevel, instances of PR_LOG levels in #defines were mapped to a fully qualified mozilla::LogLevel::* level, and all other instances were mapped to us a shorter format of LogLevel::*. Bustage for usage of the non-fully qualified LogLevel were fixed by adding |using mozilla::LogLevel;| where appropriate.
