After gdb get the commands from keyboard,does gdb put these commands into a cmd_buffer,and then gdb and compiled-in simulator access the cmd_buffer together? Does gdb and compiled-in simultor have any rules about the request and reply of commands ? _________________________________________________________________ ÓëÁª»úµÄÅóÓѽøÐн»Á÷£¬ÇëʹÓà MSN Messenger: http://messenger.msn.com/cn
