Comment at:
lldb/source/Plugins/ExpressionParser/Clang/ClangModulesDeclVendor.cpp:228
void StoringDiagnosticConsumer::SetCurrentModuleProgress(
- llvm::StringRef module_name) {
- // Ensure the ordering of:
- // 1. Completing the existing progress event.
- // 2. Beginining a new progress event.
- m_current_progress_up = nullptr;
- m_current_progress_up = std::make_unique<Progress>(
- llvm::formatv("Currently building module {0}", module_name));
+ const std::string &module_name) {
+ if (!m_current_progress_up)
