Subject: [PATCH v4 8/9] loongarch: avoid orphan input sections
Date: Sat, 27 Aug 2022 10:38:49 +0200 [thread overview]
Message-ID: <20220827083850.2702465-9-ardb@kernel.org> (raw)
In-Reply-To: <20220827083850.2702465-1-ardb@kernel.org>
Ensure that all input sections are listed explicitly in the linker
script, and issue a warning otherwise. This ensures that the binary
image matches the PE/COFF and other image metadata exactly, which is
important for things like code signing.
