MIPS uses the jump-and-link instruction jal to call functions. —The jal saves the return address (the address of the next instruction) in the dedicated register $ra, before jumping to the function. —jal is the only MIPS instruction that can access the value of the program counter, so it can store the return address PC+4 in $ra. jal Fact MIPS has 32 registers, each of which is 32 bits wide – like ARM. However, there is a MIPS64 64-bit architecture that supports 64-bit registers.
▫ Or an atomic pair of instructions. 2 .11. Pa ra. The first and last registers are special: $0 is a constant 0, and cannot be changed $31 stores the return address from a procedure Shopping for the Register MIPS Helmet?

$31: ($ra)存放返回地址，MIPS有个jal(jump-and-link,跳转并 链接)指令，在跳转到某个地址时，把下一条指令的地址放到$ra中。 用于支持子程序，例如调用程序把参数放到$a0~$a3,然后jal X跳到X过程，被调过程完成后把结果放到$v0,$v1,然后使用jr $ra返回。 Data flow in MIPS MIPS uses the following conventions for function arguments and results. —Up to four function arguments can be “passed” by placing them in Register file of the MIPS CPU. The "use" of these registers are their recommended use. You have full control over these registers, but if you put a value that MIPS is not expecting, it could have unintended consequences! What to look for.
iregdef.h är en fil som ger bl.a. möjligheten att använda namn för register, dvs. zero konventionens skull så lönar det att lära sig bra mips-programmerings-etikett :-) så kommer du att märka att register 31 (ra) innehåller värdet 0x40000000.
The instruction that puts the return address into $ra is (usually) the jal instruction. Browse other questions tagged assembly computer-architecture mips or ask your own question.

They are fairly complex, so use the simple conventions described in the material on implementing functions. Function Call Steps • Place parameters in accessible location • Transfer control to function • Acquire storage for procedure variables • Perform calculations in function and so on), we can not used a fixed location (be it a register or a memory location) for saving a register. We need a dynamic structure, something that allows us to store data without overwriting previously saved data.
