Is there any simple way or macro to load 64bit address into mips64 GPR

阅读更多关于 Is there any simple way or macro to load 64bit address into mips64 GPR

问题 I want to load 64 bit address into MIPS64 General Purpose Register(GPR). I can do it by lui $at, LabelAddr[63:48] ori $at, $at, LabelAddr[47:32] sll $at, 16 ori $at, $at, LabelAddr[31:16] sll $at, 16 ori $at, $at, LabelAddr[15:0] But, Is there any other way to do it? I got some information from this But i want to know what is "constant pool" and how to create it and how to access it? 回答1: The "simple" way is to let the assembler handle it using the dla pseudoinstruction. It will expand to

How do I access each word in Assembly?

问题 Given: .data arr: .word 2,5,1,3,4 len: .word 5 sum: .word 0 How would I access each word in "arr" such as 2, 3 and 4? Eventually, what I would like to do is find a sum of all of the values in "arr", but I'm having difficulty iterating through "arr". Thank you for your time! Additional Info: I'm using eduMIPS64 回答1: First load the address of the array into a register, then you can access the items with a constant offset. (Your assembler might support constructs such as lw $t0, arr+12 as

64 bit application: layout in memory

问题 64 bit OS refers to the bit width of the general purpose registers. It's able to process 64 bits (data + operations) at a time. We know that in order for the 64 bit system to be truly useful, programmers need to write 64 bit applications. However, I wonder what the difference is between a 32 bit application and a 64 bit application? I'm not asking what configuration changes I need to make to compile a 64 bit application; instead, I'd like to know the structural differences of the two

Loading an address in MIPS64

This is probably a simple, obvious thing I'm just not seeing, but how do I load an address in a MIPS64 processor? In a MIPS32 processor the following assembler pseudo-instruction: la $at, LabelAddr Expands into: lui $at, LabelAddr[31:16] ori $at,$at, LabelAddr[15:0] Looking at the MIPS64 instruction set, I see that lui still loads a 16-bit immediate into the upper half of a 32-bit word. There doesn't appear to be any kind of expanded instruction that loads an immediate anywhere into the upper area of a 64-bit word. This seems, then, that to do the equivalent of an la pseudo-instruction I'd
