- Subject: [PATCH v2 5/8] infcall: move assertions in 'call_function_by_hand_dummy' to an earlier spot
- References: <1561368588-21858-1-git-send-email-tankut.baris.aktemur@intel.com>
This is a refactoring that performs type assertions on the callee
function at the beginning of 'call_function_by_hand_dummy' rather
than at a later point.
