- assembly - LDUR and STUR in ARM v8 - Stack Overflow
I've had a couple of courses that touched on ARMv8 assembly, but both teachers described LDUR STUR instructions a different way and now I've become pretty lost Can
- Is there a LOAD or STORE in Legv8 that uses another register instead of . . .
Is there a load or store instruction in Legv8 that does not use a immediate offset? i do not have a value for i in the bottom question and i cant offset for data [i] when i use LDUR or STUR

- arm - How to use STR and LDR in Assembly - Stack Overflow
The ARM architecture does not support direct addressing Instead, you have to load the address into a register and then use an indexed addressing mode For example, you could do: MOV R2, #0x20000000 STR R0, [R2, #0x40] @ 0x20000000 + 0x40 = 0x20000040 STR R1, [R2, #0x44] @ 0x20000000 + 0x44 = 0x20000044 LDR R7, [R2, #0x40] We split up the address into 0x20000000 and 2 small offsets because ARM
- ARMv8: XZR use in LDUR STUR instructions assembler error
It is supposed XZR can be used in any register field of ARMv8 ISA, but when I try use in indexed addressing for load store intruction, I always obtain errors: ex2 s:3: Error: integer 64-bit register
