[gem5-dev] Change in gem5/gem5[develop]: cpu: Add a branch_prediction namespace

Daniel Carvalho (Gerrit) via gem5-dev Sun, 27 Jun 2021 19:55:18 -0700

Daniel Carvalho has uploaded this change for review. (https://gem5-review.googlesource.com/c/public/gem5/+/47303 )


Change subject: cpu: Add a branch_prediction namespace
......................................................................

cpu: Add a branch_prediction namespace

Encapsulate all branch-prediction-related files
in a branch_prediction namespace. This will allow
these files to be renamed to drop the BP suffix.

Issued-on: https://gem5.atlassian.net/browse/GEM5-982
Change-Id: I640c0caa846a3aade6fae95e9a93e4318ae9fca0
