在MIPS中,应当保留登记册,以防数据损失。 (T-S-A-V-RA REGISTERS)
根据我的MIPS参考书,以下登记册是用户-saves(须由指定职能加以保存),而其他登记册是用户-saves(需要由指定职能保存的斜线):
$s0 - $s7 (registers 16-23), the saved temporaries$gp (register 28), the global pointer$sp (register 29), the stack pointer$fp (register 30), the frame pointer$rp (register 31), the return address(说明,$rp/code> is listed as not Save in . cheatmap的其他版本。)
