[Lldb-commits] [PATCH] D61004: FuncUnwinders: Factor out address validity check

[Pavel Labath via Phabricator via lldb-commits]

Some (but not all) of the unwind plan creation functions were checking
the validity of their address range before they attempted to create the
unwind plan.

Since a FuncUnwinders object cannot do anything reasonable with an
invalid address range, in this patch I remove the checks in from the
creation functions, and instead make it's validity a class invariant.
This makes it the responsibility of whoever's creating the FuncUnwinders
to ensure it does that with a valid address range, which is easy to
achieve as there is only one place we are doing that.
