// We always generate this log message, though we only generate the panic alerts once.
//
// PC and LR are generally inaccurate in dual-core and are still misleading in single-core
// due to the gather pipe queueing data. Changing GATHER_PIPE_SIZE to 1 and
// GATHER_PIPE_EXTRA_SIZE to 16 * 32 in GPFifo.h, and using the cached interpreter CPU emulation
// engine, can result in more accurate information (though it is still a bit delayed).
// PC and LR are meaningless when using the fifoplayer, and will generally not be helpful if the
// unknown opcode is inside of a display list. Also note that the changes in GPFifo.h are not
// accurate and may introduce timing issues.
