URL: https://github.com/llvm/llvm-project/commit/b650764b16b5c8790325775ac5f87f0b1c0beca7 DIFF: https://github.com/llvm/llvm-project/commit/b650764b16b5c8790325775ac5f87f0b1c0beca7.diff LOG: [lldb][test] Add test for completing ObjCObjectType (#95405) This is a minimal reproducer for a crash where we would try to call `DumpTypeDescription` on an incomplete type. This crash surfaced as part of an NFC refactor of some of the logic in `GetCompleteQualType`: ``` (lldb) expr -l objc -- *(id)0x1234 Stack dump: 0. Program arguments: ./bin/lldb a.out -o "b main" -o run -o "expr -l objc -- *(id)0x1234" Stack dump without symbol names (ensure you have llvm-symbolizer in your PATH or set the environment var LLVM_SYMBOLIZER_PATH to point to it): 0 lldb 0x0000000102ec768c llvm::sys::PrintStackTrace(llvm::raw_ostream&, int) + 56 1 lldb 0x0000000102ec6010 llvm::sys::RunSignalHandlers() + 112 2 lldb 0x0000000102ec7fa8 SignalHandler(int) + 292 3 libsystem_platform.dylib 0x000000018c7a8c44 _sigtramp + 56 4 LLDB 0x0000000116b2030c lldb_private::TypeSystemClang::DumpTypeDescription(void*, lldb_private::Stream&, lldb::DescriptionLevel, lldb_private::ExecutionContextScope*) + 588 5 LLDB 0x00000001166b5124 lldb_private::CompilerType::DumpTypeDescription(lldb_private::Stream*, lldb::DescriptionLevel, lldb_private::ExecutionContextScope*) const + 228 6 LLDB 0x0000000116d4f08c IRForTarget::CreateResultVariable(llvm::Function&) + 2076 ``` rdar://129633122 Added: lldb/test/Shell/Expr/Inputs/objc-cast.cpp lldb/test/Shell/Expr/TestObjCIDCast.test Modified: Removed: ################################################################################ diff --git a/lldb/test/Shell/Expr/Inputs/objc-cast.cpp b/lldb/test/Shell/Expr/Inputs/objc-cast.cpp new file mode 100644 index 0000000000000..76e8197013aab --- /dev/null +++ b/lldb/test/Shell/Expr/Inputs/objc-cast.cpp @@ -0,0 +1 @@ +int main() { return 0; } diff --git a/lldb/test/Shell/Expr/TestObjCIDCast.test b/lldb/test/Shell/Expr/TestObjCIDCast.test new file mode 100644 index 0000000000000..0611171da09e2 --- /dev/null +++ b/lldb/test/Shell/Expr/TestObjCIDCast.test @@ -0,0 +1,9 @@ +// UNSUPPORTED: system-linux, system-windows +// +// RUN: %clangxx_host %p/Inputs/objc-cast.cpp -g -o %t +// RUN: %lldb %t \ +// RUN: -o "b main" -o run -o "expression --language objc -- *(id)0x1" \ +// RUN: 2>&1 | FileCheck %s + +// CHECK: (lldb) expression --language objc -- *(id)0x1 +// CHECK: error: Couldn't apply expression side effects : Couldn't dematerialize a result variable: couldn't read its memory _______________________________________________ lldb-commits mailing list lldb-commits@lists.llvm.org https://lists.llvm.org/cgi-bin/mailman/listinfo/lldb-commits
