Subject: [PATCH v3 6/6] linux-user: Add support for MIPS Loongson 2F/3E
Date: Tue,  1 Dec 2020 20:28:07 +0100	[thread overview]
Message-ID: <20201201192807.1094919-7-f4bug@amsat.org> (raw)
In-Reply-To: <20201201192807.1094919-1-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>
