URL: https://github.com/llvm/llvm-project/commit/18ef8d7fae9573913cb299ce0c82afa2f5279846 DIFF: https://github.com/llvm/llvm-project/commit/18ef8d7fae9573913cb299ce0c82afa2f5279846.diff LOG: [lldb] Call FixUpPointer in WritePointerToMemory (#152798) In architectures where pointers may contain metadata, such as arm64e, the metadata may need to be cleaned prior to sending this pointer to be used in expression evaluation generated code. This patch is a step towards allowing consumers of pointers to decide whether they want to keep or remove metadata, as opposed to discarding metadata at the moment pointers are created. See https://github.com/llvm/llvm-project/pull/150537. This was tested running the LLDB test suite on arm64e.
