Subject: [PATCH v7 09/13] selftests/sgx: Fix linker script asserts
Date: Thu,  5 Oct 2023 17:38:50 +0200	[thread overview]
Message-ID: <20231005153854.25566-10-jo.vanbulck@cs.kuleuven.be> (raw)
In-Reply-To: <20231005153854.25566-1-jo.vanbulck@cs.kuleuven.be>

DEFINED only considers symbols, not section names. Hence, replace the
check for .got.plt with the _GLOBAL_OFFSET_TABLE_ symbol and remove other
(non-essential) asserts.
