Subject: [PATCH v4 12/13] selftests/sgx: Remove redundant enclave base address save/restore
Date: Fri, 25 Aug 2023 15:32:51 +0200 [thread overview]
Message-ID: <20230825133252.9056-13-jo.vanbulck@cs.kuleuven.be> (raw)
In-Reply-To: <20230825133252.9056-1-jo.vanbulck@cs.kuleuven.be>
Remove redundant push/pop pair that stores and restores the enclave base
address in the test enclave, as it is never used after the pop and can
anyway be easily retrieved via the __encl_base symbol.
