linux-user: Add support for MIPS Loongson 2F/3A
Userland ELF binaries using Loongson SIMD instructions have the HWCAP_LOONGSON_MMI bit set [1]. Binaries compiled for Loongson 3A [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> Signed-off-by: Philippe Mathieu-Daudé <f4bug@amsat.org> Message-Id: <20201214003215.344522-7-f4bug@amsat.org> Signed-off-by: Laurent Vivier <laurent@vivier.eu>
