URL: https://github.com/llvm/llvm-project/commit/6f59f302e4358b4dc869bc298c2b9c06aa716b60 DIFF: https://github.com/llvm/llvm-project/commit/6f59f302e4358b4dc869bc298c2b9c06aa716b60.diff LOG: [lldb] Fix m_hwp_regs size for ppc64le (PR54520) The size of the m_hwp_regs array should match the default value of m_max_hwp_supported. This ensures that no out-of-bounds accesses occur, even if the array is accessed prior to a call to ReadHardwareDebugInfo(). Fixes https://github.com/llvm/llvm-project/issues/54520, see also there for additional background.
