[Lldb-commits] [PATCH] D71372: [lldb] Add additional validation on return address in 'thread step-out'

[Greg Clayton via Phabricator via lldb-commits]

clayborg added a comment.

I believe it is ok for permissions to succeed as long as they don't return invalid permissions. For any address outside any mapped ranges, we should have zero as the permissions. Looking up address mappings for zero will return

[0x00000000 - 0x100000000) ---

no permisssions are represented as "---". Then you can take the end address and look it up, and continue. So as long as we aren't getting bogus values back, we are good.
