Subject: [PATCH v3 4/9] selftests/sgx: Fix linker script asserts
Date: Sat, 19 Aug 2023 11:43:27 +0200	[thread overview]
Message-ID: <20230819094332.8535-5-jo.vanbulck@cs.kuleuven.be> (raw)
In-Reply-To: <20230819094332.8535-1-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.
