Subject: [PATCH v7 12/13] selftests/sgx: Discard unsupported ELF sections
Date: Thu,  5 Oct 2023 17:38:53 +0200	[thread overview]
Message-ID: <20231005153854.25566-13-jo.vanbulck@cs.kuleuven.be> (raw)
In-Reply-To: <20231005153854.25566-1-jo.vanbulck@cs.kuleuven.be>

Building the test enclave with -static-pie may produce a dynamic symbol
table, but this is not supported for enclaves and any relocations need to
happen manually (e.g., as for "encl_op_array"). Thus, opportunistically
discard ".dyn*" and ".gnu.hash" which the enclave loader cannot handle.
