<!--LLVM PR SUMMARY COMMENT--> @llvm/pr-subscribers-lldb Author: Pavel Labath (labath) <details> <summary>Changes</summary> The test was failing because it was looking up the immediate value from the call instruction as a load address, whereas in fact it was a file address. This worked on darwin because (with ASLR disabled) the two addresses are generally the same. On linux, this depends on the build mode, but with the default (PIE) build type, the two are never the same. The test also fails on a mac with ASLR enabled. This path fixes the code to look up the value as a file address. --- Full diff: https://github.com/llvm/llvm-project/pull/128512.diff 2 Files Affected: - (modified) lldb/source/Target/StackFrame.cpp (+6-5) - (modified) lldb/test/API/commands/frame/diagnose/dereference-function-return/TestDiagnoseDereferenceFunctionReturn.py (+1-1) ``````````diff diff --git a/lldb/source/Target/StackFrame.cpp b/lldb/source/Target/StackFrame.cpp index 4d068638f42b6..f8061ffad1466 100644 --- a/lldb/source/Target/StackFrame.cpp +++ b/lldb/source/Target/StackFrame.cpp @@ -1670,13 +1670,14 @@ lldb::ValueObjectSP DoGuessValueAt(StackFrame &frame, ConstString reg, break; case Instruction::Operand::Type::Immediate: { SymbolContext sc; - Address load_address; - if (!frame.CalculateTarget()->ResolveLoadAddress( - operands[0].m_immediate, load_address)) { + if (!pc.GetModule()) + break; + Address address(operands[0].m_immediate, + pc.GetModule()->GetSectionList()); + if (!address.IsValid()) break; - } frame.CalculateTarget()->GetImages().ResolveSymbolContextForAddress( - load_address, eSymbolContextFunction, sc); + address, eSymbolContextFunction, sc); if (!sc.function) { break; } diff --git a/lldb/test/API/commands/frame/diagnose/dereference-function-return/TestDiagnoseDereferenceFunctionReturn.py b/lldb/test/API/commands/frame/diagnose/dereference-function-return/TestDiagnoseDereferenceFunctionReturn.py index d0f6ebefa334a..8ada9a2369602 100644 --- a/lldb/test/API/commands/frame/diagnose/dereference-function-return/TestDiagnoseDereferenceFunctionReturn.py +++ b/lldb/test/API/commands/frame/diagnose/dereference-function-return/TestDiagnoseDereferenceFunctionReturn.py @@ -10,7 +10,7 @@ class TestDiagnoseDereferenceFunctionReturn(TestBase): - @expectedFailureAll(oslist=no_match(lldbplatformutil.getDarwinOSTriples())) + @expectedFailureAll(oslist=["windows"]) @skipIf( archs=no_match(["x86_64"]) ) # <rdar://problem/33842388> frame diagnose doesn't work for armv7 or arm64 `````````` </details> https://github.com/llvm/llvm-project/pull/128512 _______________________________________________ lldb-commits mailing list lldb-commits@lists.llvm.org https://lists.llvm.org/cgi-bin/mailman/listinfo/lldb-commits
