[gem5-users] Accessing dependent memory locations in a single instruction

[Leonard Peterson via gem5-users]

Hello,

I'm trying to implement an instruction "myinst" that accesses dependent 
memory locations (similar to pointer chasing) using the TimingCPU model 
(initiateAcc() and completeAcc()). For example:

             myinst r0,0x14000

The above line will first read 8 bytes from address 0x14000, which is 
say 0xFF000. It will then read 8 bytes from address 0xFF000 (or "qword 
ptr [0x14000]") into register r0. This requires issuing another 
initiateMemRead() call within the insturction's completeAcc() function. 
However, I haven't found another example instruction that does this.

I wonder whether this is currently supported by TimingCPU and what is 
the correct way to approach this?

Best,
Leonard
