Hello all,
Background:
Intel CPUs that support MPX have a limited number of bound registers. For any
program that has more objects than fit into these registers, the bounds must be
kept elsewhere. For this purpose, Bounds Tables (BT) are stored in application
memory: for each pointer there is a bound table entry with lower bound, upper
bound, check pointer value.
It would be convenient for the user to be able to access the BT and possibly
also manipulate it, through commands like: 'set/show mpx-bounds <pointer_name>
<lower-bound-value> <upper-bound-value>'.
Is there a way to add customized commands for vendor features, such as this one?
I have seen that CommandObjectCommands has a class to add commands interpreted
by command interpreter scripts and an interface for command aliases, so I
wonder if it would make sense to add something else for vendor commands. For
example, I could create a new class CommandObjectVendor that allows vendors to
create their own specific commands. In my case, for the MPX bound table, the
commands could be:
intel show mpx-bounds <pointer_name> <lower-bound-value>
<upper-bound-value>
intel set mpx-bounds <pointer_name> <lower-bound-value>
<upper-bound-value>
Thanks in advance for your help,
- V.
