[Qemu-devel] [PATCH v2 7/7] target/mips: Eliminate unreachable case for MSA instructions fill

[Mateja Marjanovic]

From: Mateja Marjanovic <mateja.marjano...@rt-rk.com>

The fill instruction doesn't support doublewords for
MIPS32 [2] (page 178), but MIPS64 supports doubleword [1] (page 179).

[1] MIPS Architecture for Programmers
    Volume IV-j: The MIPS64 SIMD
    Architecture Module
[2] MIPS Architecture for Programmers
    Volume IV-j: The MIPS32 SIMD
    Architecture Module
