Subject: [PATCH v2 6/6] linux-user: Add support for MIPS Loongson 2F/3E
Date: Tue, 1 Dec 2020 14:35:25 +0100 [thread overview]
Message-ID: <20201201133525.2866838-7-f4bug@amsat.org> (raw)
In-Reply-To: <20201201133525.2866838-1-f4bug@amsat.org>
Userland ELF binaries using Longsoon SIMD instructions have the
HWCAP_LOONGSON_MMI bit set [1].
Binaries compiled for Longsoon 3E [2] have the HWCAP_LOONGSON_EXT
bit set for the LQ / SQ instructions.
[1] commit 8e2d5831e4b ("target/mips: Legalize Loongson insn flags")
[2] commit af868995e1b ("target/mips: Add Loongson-3 CPU definition")
Reviewed-by: Richard Henderson <richard.henderson@linaro.org>
