Subject: [PATCH v3 2/7] common: elf: fix warning on 32 bits architectures
Date: Tue, 28 Apr 2020 09:50:55 +0200 [thread overview]
Message-ID: <20200428075100.17565-3-cleger@kalray.eu> (raw)
In-Reply-To: <20200428075100.17565-1-cleger@kalray.eu>
When pointers are 32 bits wide and we cast a potentially 64 bits
value in it, the compiler will yield an error. Cast that value first
into a phys_addr_t to match the architecture pointer size and then
in a void *.
