[gem5-users] Adding pseudo instructions for ARM
Hello everyone. I'm trying to implement a prefetcher which is configurable by users. To implement it, I need a new pseudo instruction "prefetcher_setup" which will be called by benchmarks to setup some prefetcher attributes. I'm using ARM64 as my ISA. I found a tutorial which I think is implementing the functionality that I want: https://www.eecg.utoronto.ca/~elsayed9/website/blog/gem5_arm_pseudo_inst.php I think this tutorial is a bit old, some parts apply to the newest version of gem5 but other parts don't. If you can help, it would be great. Thanks a lot. ___ gem5-users mailing list -- gem5-users@gem5.org To unsubscribe send an email to gem5-users-le...@gem5.org %(web_page_url)slistinfo%(cgiext)s/%(_internal_name)s

Hi Ciro, Thank you for your reply. I actually did that and managed to get it to work but forgot to update thread. I believe what confused me is the difference in the implementation of instruction decoding between AARCH64 and X86.

Shebab, I don't think such tutorial exits. Could you try to just copy what is done for one of the other instructions? It should not be hard if you try this way. Then if you have a more precise questions, do follow up.

Hello All, I was wondering if there a document or a tutorial somewhere describing how to add pseudo instructions in the ARM architecture. I went through the process before but for X86. However, I see there are some differences especially in adding the extra instructions to the ISA. Thanks in advance.
