The test binary has a symbol named `_Z3foov.cold` and the test expects the backtrace to print the name of the cold part of the function like this: ``` # SPLIT: frame #1: {{.*}}`foo() (.cold) + ``` but now it gets ``` frame #1: 0x000055555555514f split-machine-functions.test.tmp`foo() + 12 ``` Added: Modified: lldb/source/Core/FormatEntity.cpp lldb/source/Plugins/Language/CPlusPlus/CPlusPlusLanguage.cpp lldb/test/Shell/Settings/TestFrameFormatFunctionBasename.test lldb/test/Shell/Settings/TestFrameFormatFunctionFormattedArguments.test lldb/test/Shell/Settings/TestFrameFormatFunctionQualifiers.test lldb/test/Shell/Settings/TestFrameFormatFunctionReturn.test lldb/test/Shell/Settings/TestFrameFormatFunctionScope.test lldb/test/Shell/Settings/TestFrameFormatFunctionTemplateArguments.test Removed: ################################################################################ diff --git a/lldb/source/Core/FormatEntity.cpp b/lldb/source/Core/FormatEntity.cpp index a2410048e5a89..6cdfcfedf8be5 100644 --- a/lldb/source/Core/FormatEntity.cpp +++ b/lldb/source/Core/FormatEntity.cpp @@ -1809,12 +1809,11 @@ bool FormatEntity::Format(const Entry &entry, Stream &s, case Entry::Type::FunctionReturnRight: case Entry::Type::FunctionReturnLeft: case Entry::Type::FunctionQualifiers: { - Language *language_plugin = nullptr; - if (sc->function) - language_plugin = Language::FindPlugin(sc->function->GetLanguage()); - else if (sc->symbol) - language_plugin = Language::FindPlugin(sc->symbol->GetLanguage()); + if (!sc->function) + return false; + Language *language_plugin = + Language::FindPlugin(sc->function->GetLanguage()); if (!language_plugin) return false; diff --git a/lldb/source/Plugins/Language/CPlusPlus/CPlusPlusLanguage.cpp b/lldb/source/Plugins/Language/CPlusPlus/CPlusPlusLanguage.cpp index ab8e9883868ce..283e867d53bb7 100644 --- a/lldb/source/Plugins/Language/CPlusPlus/CPlusPlusLanguage.cpp +++ b/lldb/source/Plugins/Language/CPlusPlus/CPlusPlusLanguage.cpp @@ -381,34 +381,6 @@ GetDemangledScope(const SymbolContext &sc) { return demangled_name.slice(info->ScopeRange.first, info->ScopeRange.second); } -static bool PrintDemangledArgumentList(Stream &s, const SymbolContext &sc) { - assert(sc.symbol); - - Mangled mangled = sc.GetPossiblyInlinedFunctionName(); - if (!mangled) - return false; - - auto demangled_name = mangled.GetDemangledName().GetStringRef(); - if (demangled_name.empty()) - return false; - - const std::optional<DemangledNameInfo> &info = mangled.GetDemangledInfo(); - if (!info) - return false; - - // Function without a basename is nonsense. - if (!info->hasBasename()) - return false; - - if (info->ArgumentsRange.second < info->ArgumentsRange.first) - return false; - - s << demangled_name.slice(info->ArgumentsRange.first, - info->ArgumentsRange.second); - - return true; -} - bool CPlusPlusLanguage::CxxMethodName::TrySimplifiedParse() { // This method tries to parse simple method definitions which are presumably // most comman in user programs.
