Subject: [PATCH v1 09/14] DCE/DSE: inhibit .size directive for SHF_GROUP
Date: Sat,  4 Nov 2023 00:01:55 +0800	[thread overview]
Message-ID: <7807078d4612beaa3f450df9f3f3cf70b2bccb4a.1699025537.git.tanyuan@tinylab.org> (raw)
In-Reply-To: <cover.1699025537.git.tanyuan@tinylab.org>

.size directive fails in some functions with SHF_GROUP, this is not
really required for normal building, inhibit it to silence the compiling
failures with SHF_GROUP.
