Bug ID: 31911
Summary: Execution history should be saved per inferior
Product: gdb
Version: HEAD
Status: NEW
Severity: enhancement
Priority: P2
Component: record
Assignee: unassigned at sourceware dot org
Reporter: blarsen at redhat dot com
Target Milestone: ---
The record subsystem was added to gdb before we could handle multiple inferior.
As such, it was enough to have a global variable that stored things like the
the execution history, the amount of instruction saved and so on (see list of
global variables in gdb/record-full.c).
All this information should be saved on a per-inferior basis. One way to do it
is putting it inside the "class inferior" in gdb/inferior.h; either saving them
directly, or using gdb's registry system (though I'm not sure I like this
second option). Another possibility would be saving the history in the record
target, if information saved in the target is not duplicated across inferiors.
This will improve our ability to record one or many inferiors at once.
