Subject[PATCH v3 0/4] Remove dependency of check subcmd upon orc
Date
Hi,

Matt Helsley's change[1] provided a base framework to opt-in/out
objtool subcommands at compile time. This makes it easier for
architectures to port objtool, one subcommand at a time.

Orc generation relies on the check operation implementation. However,
the way this is done causes the check implementation to depend on the
implementation of orc generation functions to call if orc generation is
requested. This means that in order to implement check subcmd, orc
subcmd also need to be implemented.

These patches aim at removing that dependency, having orc subcmd
being built on top of the check subcmd.


Changes since v2 [2]:
- Rebased on recent tip/objtool/core

Cheers,

Julien
