[Gems-users] how to squash memory access if mispredicted

["shanshuchang" <shanshuchang@xxxxxxxxx>]

Hi all,

I have a problem about how does OPAL module handles the mispredict memory access.

Considering a LD instruction that has already called RUBY when it is detected to be in wrong control flow.

Here “squash” is involved to squash the pipeline. I am wondering how is the under executing LD instruction squashed in detail, especially how the ruby request is terminated.

 

Thanks in advance!
