Sure, will update. Just to double-check a couple points:
# I'll actually want to pass `&addr_range` at all three callsites, rather
than passing `nullptr` at two of them, correct? (at the callsite on 154 to
preserve the `addr_range` previously defined on 175, and at the callsite on
431to preserve the `addr_range` previously defined on 470)
# I see you removed the `resolve_scope & resolved_scope` check. Am I correct
that that was intentional and it's redundant with the checks in
`GetAddressRange` that require `function` or `symbol` to be non-null, or is
there something more subtle going on here?
Thanks.
