URL: https://github.com/llvm/llvm-project/commit/d87c80bd46d9dc761b048cad48838a039cff214a DIFF: https://github.com/llvm/llvm-project/commit/d87c80bd46d9dc761b048cad48838a039cff214a.diff LOG: [lldb] Do not narrow `GetIndexOfChildWithName` return type to int (#165453) Modify the python wrapper to return uint32_t, which prevents incorrect child name-to-index mapping and avoids performing redundant operations on non-existent SBValues.
