 [lldb] Rename Logging.h to LLDBLog.h and clean up includes 2022-02-03T13:47:01+00:00 Pavel Labath pavel@labath.sk 2022-02-03T12:26:10+00:00 c34698a811b137b705738b7f8d193bc896027fb8 Most of our code was including Log.h even though that is not where the "lldb" log channel is defined (Log.h defines the generic logging infrastructure). This worked because Log.h included Logging.h, even though it should. After the recent refactor, it became impossible the two files include each other in this direction (the opposite inclusion is needed), so this patch removes the workaround that was put in place and cleans up all files to include the right thing. It also renames the file to LLDBLog to better reflect its purpose.

Support AArch64/Linux watchpoint on tagged addresses

AArch64 architecture support virtual addresses with some of the top bits ignored.
These ignored bits can host memory tags or bit masks that can serve to check for
authentication of address integrity. We need to clear away the top ignored bits
from watchpoint address to reliably hit and set watchpoints on addresses
containing tags or masks in their top bits.

This patch adds support to watch tagged addresses on AArch64/Linux.
